Customs Window

Customs Window provides customs declarations and compliance services for imports and exports across multiple jurisdictions. Its listed coverage includes Irish AIS and AES, UK CDS, Netherlands DECO and DMS, Swedish e-commerce imports, and EU ICS2 across all member states. Declarations can be uploaded in bulk through Excel, CSV, or API data, with EU TARIC rules applied automatically. The company's AI tools are described as auditing declarations and guiding users through steps. Reports support financial, operational, and regulatory analysis, including finding errors ahead of customs audits. Listed integrations include Shopify, marketplaces, platforms, and ERP systems; APIs handle transfers, notifications, uploads, and declaration actions from a customer's platform. The mobile app provides declaration updates, automatic PBN creation, and import/export rule checks for drivers and warehouse staff. A digital payment facility collects customs duties and taxes, and the site says it supports BTC export/import processes. Pricing is on request for a monthly subscription with unlimited users. Intended customers include enterprises, e-commerce businesses, customs agents, SMEs, and logistics facilitators.

DutyDeclared

DutyDeclared is a cloud-based platform for preparing, validating, managing and submitting UK customs import declarations to HMRC through the CDS API. It extracts structured information from invoices, packing lists, export declarations and transport documents to populate declaration fields. Its Quick Editor lets users review uncertainties and edit HS codes or VAT, with totals syncing automatically. Validation checks fields against current trade regulations and flags risks related to UK/EU compliance, origin, value and documents.

Users can submit declarations to HMRC CDS, receive status notifications, track submissions, maintain audit trails and make amendments. AI assists with document extraction and HS commodity code classification, but users must review and verify its suggestions. The platform integrates with HMRC CDS through the official API using OAuth 2.0 and offers API access for third-party integrations. The free tier advertises 10 entries each month. Starter costs £250 a month and offers a 14-day trial; Professional costs £850 a month. Enterprise pricing is custom. The platform is aimed at importers, exporters, customs brokers, freight forwarders and trade teams.
