Customs software is a digital platform that connects your business directly to HMRC’s Customs Declaration Service and other UK and EU government customs systems, allowing you to prepare, validate and submit import, export, transit and safety declarations electronically. It replaces manual, paper-based declaration processes with an automated workflow that is faster, more accurate and always aligned with current HMRC rules.
Businesses evaluating a customs compliance software solution should look for a platform that covers not just declaration submission, but the full compliance lifecycle โ from document intake and data validation through to clearance confirmation and HMRC audit trail storage.
Every UK business that imports or exports goods internationally requires a formal customs declaration for each shipment. Since the UK left the European Union in January 2021, this includes all goods moving between Great Britain and EU member states, a change that increased the volume of UK customs declarations from approximately 55 million to over 300 million per year. Customs software makes this volume manageable for businesses of every size, from sole traders importing a handful of shipments per month to customs brokers filing thousands of declarations weekly.
Quick definition: Customs software automates the filing of customs declarations to government systems including HMRC CDS, NCTS Phase 5, ENS Safety and Security, and EU ICS2. It handles the full declaration lifecycle from document reading and data extraction through to submission, clearance confirmation and audit trail storage.
Aย report by the National Audit Officeย shows the need for CDS; it concludes,
โHMRC has developed a new customs system, which was part of HMRCโs previous programme. However, given the customs problems faced by UK imports and exports, it should have been done earlier.โ
Welcome to the age of technology, where software solutions have gained heights and made our lives easier. Customs software is one such relief where trading on borders becomes convenient, the documentation web is simplified, and services are accurately authentic. The best part is that it is speedy & reliable.
CDS software streamlines the customs clearance process, ensuring ease of operation and accuracy.
These terms are often used interchangeably, but they describe slightly different functions. Customs declaration software refers specifically to the tools that prepare and submit the formal customs declaration document to HMRC or EU customs systems. Customs clearance software refers more broadly to the complete workflow: receiving the cargo notification, managing documentation, submitting the declaration, tracking the clearance decision and releasing the goods for delivery.
In practice, the best modern platforms do both. A good customs software platform takes you from receiving a commercial invoice through to the goods being released at the border, declaration and clearance in one integrated workflow. When you see vendors describe their product as ‘customs clearance software’, they typically mean this end-to-end workflow rather than just the submission step.
If you have been using UK customs software for more than three years, you will have heard about the transition from CHIEF to CDS. This is the most significant change to UK customs infrastructure since the computerisation of customs declarations in the 1990s. Understanding it is essential for choosing the right customs software today.
CHIEF (Customs Handling of Import and Export Freight) was HMRC’s customs processing system from 1994 until 2023. It served UK businesses reliably for nearly 30 years but was built on technology and data formats that could not handle the volume of declarations required after Brexit or the modern integration requirements of UK supply chains.
HMRC developed CDS (Customs Declaration Service) as CHIEF’s modern replacement. CDS is built on REST API web services, uses EU Union Customs Code aligned data elements, supports 10-digit commodity codes and provides real-time integration with HMRC’s compliance and risk assessment systems. The transition was completed in 2023.
| Change Area | What Changed When Moving from CHIEF to CDS |
| Procedure codes | CHIEF used a 3-part procedure code. CDS uses a 7-digit procedure code (also written as a 4-digit plus 3-digit combination). Every declaration process code had to be remapped for CDS. |
| Commodity codes | CHIEF accepted 8-digit commodity codes. CDS requires 10-digit codes from the UK Global Trade Tariff. Businesses had to update all their commodity code libraries. |
| Technical interface | CHIEF used EDIFACT messaging. CDS uses modern HTTPS REST API. Software vendors had to rebuild their HMRC connectivity from the ground up. |
| Postponed VAT Accounting | PVA was introduced after Brexit and required new CDS data elements. CHIEF never fully supported PVA natively. CDS handles PVA declaration and monthly statement generation. |
| Declaration data fields | CDS has more data elements than CHIEF and aligns with the EU Union Customs Code structure. Some fields that were optional in CHIEF became mandatory in CDS. |
| Deadline for transition | CHIEF for exports closed 30 March 2023. CHIEF for imports closed 30 November 2023. From 1 December 2023, all UK customs declarations have been CDS-only. |
Any customs software you consider today must be fully CDS-compatible. This means it connects to HMRC CDS via the approved API, supports all current CDS data elements and procedure codes, generates valid MRNs, and is listed on the HMRC software developer documentation as a tested and approved integration. If a vendor cannot confirm CDS compatibility with evidence, do not use their software.
iCustoms was built for CDS from the outset, not migrated from CHIEF. This matters practically: CDS-native software does not carry the legacy data models and procedure code workarounds that CHIEF-era platforms had to retrofit. Every data field, validation rule and HMRC API call in iCustoms was designed for CDS.
As a purpose-built CDS customs document software UK businesses can rely on, iCustoms eliminates the compatibility gaps that migrated platforms carry. For importers and exporters looking to deploy automated customs filing software across their full shipment volumes, a CDS-native build means faster implementation, fewer edge-case errors, and no debt from legacy procedure code workarounds.
iCustoms simplifies the automated processes and ensures error-free customs declarations.
Road hauliers have specific customs software requirements that go beyond what a standard importer or exporter needs. If you operate vehicles on RoRo routes between Great Britain and the EU, your customs software must integrate with GVMS and support S&S GB declarations. These are not optional extras, they are mandatory for operating legally at UK RoRo ports.
Want to learn how you can manage Customs Effortlessly? Start Now!
GVMS (Goods Vehicle Movement Service) is HMRC’s system for managing road freight vehicle movements on RoRo routes between Great Britain and the EU, and for transit movements through Great Britain. Before a vehicle can board a RoRo ferry, the haulier must submit all the relevant customs declarations (or customs procedure references) into GVMS and generate a Goods Movement Reference (GMR). The port checks the GMR before allowing the vehicle to board.
If your customs software does not support GVMS, your vehicles cannot move goods through RoRo routes without using a third party to generate the GMR. iCustoms integrates GVMS GMR generation into the declaration workflow so hauliers can submit their CDS declarations and generate the GMR from the same platform.
Safety and Security Great Britain (S&S GB) declarations are required for goods arriving in Great Britain from outside the UK by road freight. Hauliers must file an Entry Summary Declaration (ENS) with safety and security data before the vehicle arrives at the UK port. The advance notification window for road freight from EU ports is typically 2 hours before arrival. Missing this window can result in the vehicle being refused entry to the port until the ENS is filed and accepted.
iCustoms supports S&S GB ENS filing through the iZap batch filing tool. For hauliers with multiple vehicles arriving daily, iZap allows batch submission of S&S GB declarations with automatic timing management so that submissions are made within the correct advance notification window.
At most UK ports, customs declarations for road freight must be pre-lodged, submitted and accepted by HMRC before the vehicle arrives at the port, not at the port gate. This requires customs software that can submit CDS declarations with the correct pre-arrival timing and link the resulting MRN to the GVMS GMR for the specific vehicle movement.
At inventory-linked ports including Dover, Folkestone and Eurotunnel, declarations must also be linked to the inventory records held by the port’s community system. Customs software that does not support inventory linking cannot complete the release process at these ports. Goods arriving without an inventory-linked declaration cannot be released.
Customs broker software, also called customs brokerage software or customs agent software, is a specialist category of customs declaration platform designed for the multi-client, high-volume filing environment of professional customs brokers and agents. It differs from single-importer software in scale, complexity, and workflow: a broker may file hundreds of declarations per day for dozens of different clients, each with their own EORI, duty deferment account, commodity code library, and HMRC audit trail requirements.
Choosing the right customs broker software is one of the most significant technology decisions a customs brokerage firm makes. The software needs to support not just the declaration mechanics but the entire brokerage workflow: client onboarding, document collection, declaration preparation, submission, clearance tracking, duty reporting, and HMRC audit compliance.
For brokers handling high document volumes across multiple clients, customs broker document processing software with AI-powered data extraction is particularly critical โ it eliminates the bottleneck of manually keying commercial invoice and packing list data into declaration fields for every shipment. The best customs filing software for brokers combines this document intelligence with bulk filing, multi-client EORI management, and full HMRC audit trail storage in a single platform.
Customs brokers file declarations on behalf of importers and exporters who do not have the in-house resource or expertise to file their own. The broker acts as either a direct representative (in the client’s name) or an indirect representative (in their own name, accepting joint liability). Broker-grade customs software must handle the scale and complexity of multi-client filing that individual importer software is not designed for. The table below sets out what to look for.
| Broker Requirement | What to Look for in Customs Software |
|---|---|
| Multi-client account management | Software must allow brokers to maintain separate client profiles, EORI numbers, duty accounts and declaration histories for each client. Mixing client data is a compliance failure that can result in HMRC sanctions. |
| Bulk and batch filing | Brokers file dozens to hundreds of declarations per day. Software must support batch CSV upload, declaration templates per client or commodity type, and automated submission queuing. Automated data extraction trade documents capability โ reading invoices and packing lists to pre-fill declarations โ is equally essential for brokers managing high daily volumes. |
| Indirect and direct representation modes | The software must be able to switch between direct representation (declaration in client’s name) and indirect representation (declaration in broker’s name) per declaration, as HMRC rules differ between the two modes. |
| HMRC audit trail | Revenue and HMRC can audit declarations going back four years. Broker software must store every declaration, all supporting documents, and all HMRC correspondence in a searchable, exportable format that satisfies HMRC’s record-keeping requirements. |
| Client reporting and billing | Brokers need to report declaration activity, duty amounts and filing charges to each client separately. Software with built-in reporting reduces the administrative burden of client account management. |
Not every UK business that needs customs software is a large importer or logistics company. Many small businesses found themselves needing customs software for the first time after Brexit, when goods they had been buying from EU suppliers suddenly required formal declarations. For these businesses, the pricing model of customs software matters as much as the feature set.
| Pricing Model | Suitable For |
|---|---|
| Multi-client account management | Best for small importers and exporters with irregular shipment volumes. You pay per declaration submitted, with no monthly minimum. Predictable cost that scales with your import/export activity. |
| Monthly subscription (tiered by volume) | Best for businesses with regular, predictable declaration volumes. Monthly fee covers a certain number of declarations with overage pricing above the cap. |
| Annual enterprise contract (CDS-ERP Integration) | Best for large brokers, freight forwarders or manufacturers with high volumes. Fixed annual fee for unlimited or very high volume declarations, typically includes CDS software ERP integration and dedicated support. |
| Agent-assisted (outsourced) | Not self-service software you provide documents and a customs agent files on your behalf. Higher per-declaration cost than self-service but no training or software management required. Less suitable if you want in-house control. |
For small businesses filing their first customs declarations, iCustoms offers a guided declaration wizard (iWiz) that walks you through the declaration fields step by step, validates your commodity code, calculates the duty and submits directly to HMRC CDS. No customs expertise required to get started. Contact the iCustoms team for current pricing based on your expected monthly declaration volumes.
The following checklist covers the criteria that matter most for UK businesses evaluating customs software in 2026. Use it to assess any platform you are considering, including iCustoms.
| Criterion | What to Verify |
|---|---|
| CDS compatibility | Is the software listed on HMRC’s software developer pages? Can it file import and export declarations to CDS with valid MRN return? |
| NCTS Phase 5 support | Does it support NCTS Phase 5 transit declarations for goods moving under Common Transit Convention? |
| ENS / S&S GB support | Does it file Safety and Security Great Britain declarations and ENS for goods arriving from the EU? |
| ICS2 support | Does it file ICS2 Entry Summary Declarations for UK exporters shipping goods into EU member states? |
| GVMS integration | For road hauliers: does it generate GVMS Goods Movement References and link them to CDS declarations? |
| AI document processing | Does it read commercial invoices, packing lists and transport documents and auto-populate declaration fields? |
| Commodity code classification | Does it include an AI-powered or rule-based classification tool for finding the correct 10-digit UK GTT commodity code? |
| Postponed VAT Accounting | Does it correctly handle PVA elections on import declarations and generate the data needed for monthly PVA statements? |
| ERP and TMS integration | Does it offer API connectivity to your SAP, Oracle, Dynamics or other business systems? |
| Pricing and volume model | Is pricing per declaration, monthly, or annual? Is there a free trial or guided evaluation period? |
| HMRC compliance updates | Does the provider automatically update the software when HMRC changes tariff codes, procedure codes or CDS technical requirements? |
| Audit trail and reporting | Does it store all declarations and HMRC correspondence in a format that satisfies HMRC’s four-year lookback audit requirement? |
| Multi-client support (brokers) | For customs brokers: does it support separate client profiles, indirect representation mode, and bulk filing? |
| UK-based support | Is technical and compliance support available during UK business hours from a team with direct HMRC CDS knowledge? |
| Approval and certification | Is the platform on the HMRC developer register? Does it hold any additional accreditations relevant to your sector? |
The best HMRC filing software for UK businesses is not the one with the most features. It is the one that fits your declaration volume, your team’s technical capability, and your specific customs regime requirements. That said, all high-quality HMRC filing software must meet a baseline of capability to be considered a serious option in 2026.
At minimum, the best HMRC filing software must: connect directly to HMRC CDS via an approved API and be listed on HMRC’s software developer documentation; support both import and export declarations on CDS; validate data against current HMRC tariff rules before submission; generate a valid MRN on acceptance; and store all declarations and HMRC responses in a format that satisfies HMRC’s four-year audit lookback. Software that does not meet all five of these criteria is not a complete HMRC filing solution.
Beyond the baseline, the best HMRC filing software for most UK businesses in 2026 will also include AI document processing to reduce manual data entry, cloud SaaS delivery for accessibility and automatic regulatory updates, and support for the full declaration portfolio: CDS imports and exports, NCTS Phase 5 transit, S&S GB safety and security, ICS2 for EU-bound shipments, and GVMS for road hauliers. iCustoms meets all of these criteria and is listed on HMRC’s approved software developer register.
iCustoms is a UK and Ireland customs software platform built for CDS from the ground up, not migrated from a legacy system. It handles the complete customs workflow for importers, exporters, customs brokers and freight forwarders using a combination of AI document processing and direct government system connectivity.
| iCustoms Capability | What It Delivers |
|---|---|
| HMRC CDS declarations (iWiz / iAIS / iAES) | Direct submission of import and export declarations to HMRC CDS. MRN returned in real time. No separate HMRC portal login required. |
| AI document processing (IDP) | Reads commercial invoices, packing lists, CMRs and airway bills. Auto-populates declaration fields with customs document processing 99% accuracy. Teams that save time on customs documentation across dozens of daily shipments will find this the highest-impact feature in the platform โ cutting declaration prep from 15 minutes to under 3 minutes per consignment. |
| AI commodity code classification (iClassification) | AI-driven classification to 10-digit UK GTT code (and EU CN code). Reduces misclassification risk and pre-entry admin time. |
| Batch ENS filing (iZap) | Batch Safety and Security GB ENS declarations and ICS2 ENS for EU-bound shipments. Advance timing management built in. |
| NCTS Phase 5 transit (iNCTS) | Full NCTS Phase 5 transit declaration management for T1 and T2 movements under the Common Transit Convention. |
| Duty calculation (iCalculator) | Calculates duty, import VAT (including PVA), excise and other charges. API available for integration with procurement and ERP systems. |
| Compliance validation | Checks every declaration against current HMRC tariff rules, procedure codes and prohibited goods lists before submission. |
| Audit trail | Every declaration, document and HMRC response stored and searchable. Satisfies HMRC’s four-year audit lookback requirement. |
| GVMS integration | For hauliers: GMR generation linked to CDS declarations for RoRo port pre-notification. |
| ERP / TMS integration | API connectivity to SAP, Oracle, Microsoft Dynamics and other business systems. Eliminates duplicate data entry. |
For exporters managing high volumes of outbound shipments, iCustoms also functions as an export manifest automation tool โ reading export documentation, grouping shipment data by departure schedule, and pre-populating batch export declarations for submission to HMRC CDS in a single workflow.
Cloud customs filing software is a SaaS (Software as a Service) platform that allows UK businesses to file import, export, transit and safety and security declarations to HMRC and EU government systems through a web browser, without installing any software locally. All processing, data storage, HMRC API connections, and regulatory updates happen in the cloud, managed by the software provider.
Until recently, many customs software platforms were desktop-installed applications that required on-premise servers, IT maintenance, and manual software updates each time HMRC or the European Commission changed tariff codes or procedure requirements. Cloud SaaS customs platforms have replaced this model for most UK businesses because they remove the IT overhead and ensure that every user is always working on the current, compliant version of the software.
Access from any device, any location: a cloud SaaS customs platform works in a standard web browser. Your team can file declarations from the office, a warehouse, a port facility, or while working remotely. There is no dependency on a specific PC or server.
Automatic regulatory updates: HMRC updates commodity codes, procedure codes, and CDS technical requirements regularly. Cloud customs software providers push these updates to all users automatically. With desktop software, businesses had to download and install updates manually, creating a gap during which declarations might be filed against outdated tariff data.
Multi-user collaboration with role controls: cloud platforms allow multiple team members to work on declarations simultaneously, with role-based access so that junior staff can prepare declarations while senior staff review and submit. This reduces the single-point-of-failure risk that desktop systems create.
Scalability without infrastructure cost: cloud customs SaaS platforms scale with your declaration volume. You add users and increase filing capacity by upgrading your subscription, not by purchasing server hardware or additional software licences.
iCustoms is a cloud-native SaaS customs platform. It does not have a desktop version. All services, including CDS import and export declarations, NCTS transit, S&S GB safety and security, ICS2, GVMS integration, and AI document processing, are delivered through a secure web interface. There is no software to install, no server to maintain, and no manual update process.
For UK exporters, the iCustoms cloud platform provides a particularly clear benefit. Export declarations often need to be filed at short notice based on loading confirmations. With iCustoms, any team member with the appropriate authorisation can log in from any device, retrieve the commercial invoice, let the IDP AI read and extract the export data, and submit the CDS export declaration within minutes. The Export Accompanying Document (EAD) is returned digitally through the platform.
iCustoms is also a SaaS customs clearance software solution, managing the complete workflow from document receipt through declaration submission to clearance confirmation in one integrated platform, without requiring separate tools for each stage of the process.
An HMRC export declaration is a formal submission to HMRC’s Customs Declaration Service (CDS) that is required for all commercial goods leaving the UK. It captures key information about the goods, the exporter, the consignee, and the transport method, and triggers HMRC’s export control checks. Once accepted, HMRC issues an Export Accompanying Document (EAD) that must travel with the goods to the UK port of exit.
Export declarations apply to goods leaving Great Britain for any destination outside the UK customs territory, including EU member states, the Channel Islands, and all other international destinations. They also apply to goods moving from Northern Ireland to non-EU destinations under certain circumstances. If you are exporting commercially, you need an export customs declaration for each shipment.
An export customs declaration on HMRC CDS requires the following key data elements:
Transport document reference: the bill of lading, airway bill, or road consignment note number.
Step 1: Gather your export data. Collect the commercial invoice, packing list, and any export licences or certificates of origin required for your goods or destination country.
Step 2: Classify your goods. Confirm the correct 10-digit commodity code for your goods using the UK Global Trade Tariff. Export commodity codes are the same as import commodity codes for the same goods.
Step 3: Submit the export declaration to HMRC CDS. Your customs software connects to CDS via HMRC-approved API and transmits the declaration data. HMRC conducts its risk and control checks in real time.
Step 4: Receive the Movement Reference Number (MRN) and Export Accompanying Document (EAD). HMRC returns an MRN confirming acceptance and generates the EAD. The EAD is your proof that export formalities have been completed. Keep the MRN as it may be needed for returned goods procedures if the goods are rejected and come back.
Step 5: Present the EAD at the port of exit. At UK ports with export inventory control, your EAD or its reference number must be presented to the port community system before goods can be loaded for export. Your customs software should support inventory linking at major UK export ports.
iCustoms iWiz files export declarations to HMRC CDS and returns the MRN and EAD digitally through the platform. The iCustoms IDP reads your commercial invoice and packing list, extracts the export data, and pre-populates the declaration fields. This reduces export declaration preparation time from 15 minutes or more to under 3 minutes for a standard commercial shipment.
Many UK businesses that export also import, and need a customs software platform that handles both directions with equal capability. Export import customs declaration requirements differ in several ways: exports use different procedure codes, the EAD is the output document rather than an import clearance decision, and some classifications differ between the UK import tariff and UK export tariff.
iCustoms handles both export and import declarations through the same CDS connection. An exporter who also imports can manage their full two-way declaration portfolio from one platform, with separate import and export declaration histories, shared commodity code libraries, and unified HMRC audit trail storage.
Export customs cleared means that HMRC has accepted your export customs declaration and issued an Export Accompanying Document (EAD). At this point, your goods have been formally cleared for export from the UK. The EAD confirms that export formalities are complete and that the goods may leave the UK customs territory.
At customs-controlled UK port facilities, port officials or the port community system will verify that a valid EAD or its reference exists before permitting the loading of your goods. Goods for which no accepted export declaration can be confirmed cannot be loaded for export from these facilities. This is why submitting your export declaration before the loading deadline is critical, not just a legal formality.
Once your goods are physically exported and confirmed as departed, HMRC closes the export declaration. At this stage, the EAD status moves to finalised. For VAT zero-rating on exports, the finalised EAD serves as one of the key pieces of evidence that the goods have genuinely left the UK.
If goods you have exported are returned to the UK, for example because an overseas customer has rejected the delivery or cancelled the order, you may be able to re-import them without paying UK import duty again. This is called Returned Goods Relief (RGR) and it is the UK customs mechanism that prevents double-charging of duty on goods that never permanently left UK commercial circulation.
For Returned Goods Relief to apply, the following conditions must be met: the goods must be re-imported within 3 years of the original export; the goods must be in the same state as when exported, meaning they have not been processed, altered, or repaired overseas in a way that increases their value; you must be able to provide the original export MRN as evidence of the prior export; and the goods must be re-imported by, or on behalf of, the person who originally exported them.
On the re-importation customs declaration, you use Customs Procedure Code (CPC) 61 23 000 for goods being returned in the same state under Returned Goods Relief. iCustoms iWiz handles RGR declarations, allowing you to reference the original export MRN and apply the correct CPC automatically. If import VAT was reclaimed or zero-rated on the original export, additional adjustments may be needed and it is worth confirming the VAT position with your accountant.
Authority note: Returned Goods Relief is provided under Article 203 of the UK Tariff Regulations. HMRC Customs Notice 236 “Returned goods” provides the full conditions and procedures. For goods processed or repaired overseas before return, Outward Processing Relief (OPR) may apply instead of RGR.
iCustoms is directly integrated with HMRC’s Customs Declaration Service (CDS). All declarations submitted through iCustoms are transmitted to HMRC via approved API channels. iCustoms supports CDS import and export declarations, NCTS Phase 5 transit, ENS S&S GB, ICS2 and EU AIS/AES declarations from a single platform.

Customs software is a digital platform that connects your business to HMRC's Customs Declaration Service and other government customs systems, allowing you to file import, export, transit and safety declarations electronically. It replaces manual declaration preparation with an automated workflow that validates your data against HMRC rules, generates the correct tariff and procedure codes, submits the declaration to HMRC, and returns a Movement Reference Number (MRN) confirming clearance. Modern customs software also uses AI to read shipping documents and auto-populate declarations, reducing filing time from hours to minutes.
Customs declarations are mandatory for all goods entering or leaving the UK from non-UK countries. Since Brexit, this includes all goods moving between Great Britain and the EU. Customs declarations must be submitted electronically to HMRC CDS โ there is no paper-based alternative for commercial shipments. While you are not legally required to use a specific customs software product, you must use a CDS-compatible method to file. The options are: use a CDS-approved customs software platform directly, or use a customs agent who files on your behalf using their own software. Businesses with regular import or export volumes typically find that in-house customs software is more cost-effective than agent-only filing above a threshold of around 10 to 20 declarations per month.
The Customs Declaration Service (CDS) is HMRC's current electronic system for receiving and processing UK customs declarations. It replaced the legacy CHIEF system, which closed for exports in March 2023 and for imports in November 2023. All UK customs declarations for imports, exports and supplementary filings now go through CDS. CDS uses a modern REST API interface, supports 10-digit commodity codes from the UK Global Trade Tariff, and handles Postponed VAT Accounting natively. Any customs software used for UK declarations must be CDS-compatible.
HMRC's CDS (Customs Declaration Service) replaced CHIEF (Customs Handling of Import and Export Freight). CHIEF closed for export declarations on 30 March 2023 and for import declarations on 30 November 2023. CDS uses different data formats, procedure codes and API connectivity compared to CHIEF. Businesses and their software vendors had to migrate their declaration processes to CDS before these deadlines. Customs software that was built for CHIEF required significant redevelopment to support CDS. iCustoms was built natively for CDS and did not require a CHIEF migration.
Customs software pricing varies by vendor and volume model. Self-service platforms typically charge per declaration for low-volume users (ranging from a few pounds to around ten to twenty pounds per declaration depending on complexity and features), or a monthly subscription for regular importers and exporters. Enterprise and broker-grade platforms with ERP integration and multi-client management are priced on annual contracts based on declaration volumes and user seats. For small businesses new to customs filing, per-declaration pricing with no monthly minimum is typically the most cost-effective starting point. Contact iCustoms for current pricing based on your expected monthly declaration volumes and the specific systems you need to connect to.
Yes. The best customs software platforms handle the full range of UK trade flows: import declarations to HMRC CDS for goods arriving in the UK, export declarations to HMRC CDS for goods departing the UK, transit declarations through NCTS Phase 5 for goods moving under Common Transit Convention procedures, Entry Summary Declarations (ENS) for goods arriving in the UK, Safety and Security GB declarations for road freight, and ICS2 ENS for goods being shipped to EU member states. iCustoms supports all of these from a single platform login, so you do not need separate systems for different declaration types.
Standard customs software requires a user to manually type or copy data from shipping documents (invoices, packing lists, transport documents) into the declaration fields. AI customs software uses Intelligent Document Processing (IDP) to read the shipping documents directly, extract the relevant customs data automatically, and populate the declaration fields without manual entry. The practical difference is speed (under 3 minutes per declaration with AI vs 15 to 20 minutes manually) and accuracy (AI extraction eliminates transcription errors that cause most declaration rejections). AI software also typically includes AI-powered commodity code classification, which suggests the correct HS or UK GTT code based on a description of the goods.
Yes, the leading customs software offer API connectivity to major ERP and TMS systems. Integration means that commercial order data โ supplier information, purchase order values, product descriptions, delivery addresses โ flows directly from your ERP into the customs declaration without manual re-entry. This eliminates duplicate data entry and ensures the customs value declared to HMRC matches the value recorded in your accounting system. iCustoms provides an API that connects to SAP, Oracle, Microsoft Dynamics and other business systems. Contact the iCustoms team for specific integration documentation for your ERP platform.
GVMS (Goods Vehicle Movement Service) is HMRC's system for managing road freight vehicle movements on RoRo ferry routes between Great Britain and the EU. Before a vehicle can board a RoRo ferry, the haulier must submit all the relevant customs declaration references into GVMS and generate a Goods Movement Reference (GMR). The port checks the GMR before allowing boarding. Without a GMR, the vehicle will be turned away. Customs software with GVMS integration generates the GMR automatically once the customs declarations are submitted to CDS, linking the clearance status to the specific vehicle and sailing. Without software that handles this end-to-end, hauliers must manually switch between CDS and GVMS, increasing the risk of timing errors that delay vehicles.
Customs declaration software refers to the specific function of preparing and submitting the formal customs declaration to HMRC CDS or EU customs systems. Customs clearance software refers to the broader workflow: receiving cargo notifications, managing documentation, submitting declarations, tracking the HMRC clearance decision, and releasing goods for delivery. In practice, modern platforms do both. When a vendor describes their product as 'customs clearance software', they typically mean the end-to-end workflow rather than just the submission step. The terms are used interchangeably in the UK market. iCustoms covers the full clearance workflow from document receipt to goods released, not just the declaration submission step.
Cloud customs filing software is a SaaS platform that lets you file customs declarations to HMRC and EU government systems through a web browser without installing any software locally. All HMRC connections, data storage, and regulatory updates are managed in the cloud by the software provider. iCustoms is a cloud-native SaaS customs platform: there is no desktop version and no local installation required.
A customs SaaS (Software as a Service) platform is a subscription-based customs software product delivered entirely through the internet. You pay a monthly or per-declaration fee and access the software through a web browser. Unlike traditional on-premise customs software, a SaaS platform updates automatically when HMRC changes tariff codes or procedure requirements, and scales with your declaration volume without additional infrastructure.
An HMRC export declaration is a formal submission to HMRC's Customs Declaration Service (CDS) required for all commercial goods leaving the UK. It records the commodity code, declared value, exporter EORI, consignee, and transport details. Once accepted, HMRC issues an Export Accompanying Document (EAD) which must accompany the goods to the port of exit. Goods cannot be loaded for export at customs-controlled UK ports without a valid accepted export declaration.
Export customs cleared means HMRC has accepted your export declaration and issued an Export Accompanying Document (EAD). The EAD confirms that your goods may leave the UK customs territory. Port facilities will verify the EAD reference before allowing goods to be loaded for export. Once the goods have physically departed, HMRC finalises the export declaration, which serves as evidence for VAT zero-rating on the export.
The export goods return procedure is formally called Returned Goods Relief (RGR). It allows goods that were previously exported from the UK to be re-imported without paying import duty again, provided they return within 3 years in the same condition as exported and the original export MRN is available. On the re-importation declaration, Customs Procedure Code 61 23 000 is used. iCustoms iWiz handles RGR import declarations and references the original export automatically.
Customs broker software, also called customs brokerage software, is a multi-client customs declaration platform designed for customs agents and brokers who file declarations on behalf of multiple importers and exporters. Unlike single-importer software, broker software supports separate client profiles with individual EORI numbers, duty deferment accounts, and declaration histories. It includes bulk filing, indirect and direct representation modes, and HMRC-compliant audit trail storage per client. iCustoms supports all of these broker requirements from a single cloud SaaS platform.
