Customs4trade (C4T) has developed CAS, a customs and excise automation software solution that turns customs from a compliance burden into a competitive advantage. It helps companies manage automated customs and excise operations globally with a digital-first approach, enabling cost-effective, efficient, and compliant operations at scale. CAS automates customs declarations, special procedures, and excise management, cutting manual work and complexity so customs becomes a source of speed and control rather than friction. By digitising and streamlining customs processes end to end, CAS helps you reduce costs, accelerate your supply chain, and strengthen compliance, giving businesses an edge over competitors. Companies can cut administrative and duty costs by up to 80% and speed up lead times with declarations released in less than five minutes. CAS allows you to run accurate, consistent, and audit-ready customs operations across countries, turning compliance into a strategic advantage rather than a cost centre. CAS is built on Microsoft Azure and delivered as a SaaS solution, ensuring scalability, security, and continuous updates.
Digital-first customs automation — zero-touch declarations for EU and UK operations
View company profileEnd-to-end automation of customs and excise processes for enterprises managing high-volume, complex trade flows across multiple countries. CAS centralises declarations, special procedures (inward/outward processing, customs warehousing), and excise management (including tax warehousing and EMCS) into a single platform, replacing fragmented broker-dependent workflows with self-filing control.
CAS is one of the few platforms built to handle special procedures and excise natively, not as an afterthought bolted onto a standard declarations engine. Enterprises running bonded and tax warehouses, inward processing regimes, or excise goods movements get purpose-built automation and audit trails for these complex regimes, alongside full visibility through Insights, rather than needing separate tools or manual workarounds for the parts of customs that actually create risk and cost at scale.
Mid-to-large enterprises with high transaction volumes, multi-country operations, and exposure to special procedures or excise duty, including operators of tax and bonded warehouses, manufacturers, and distributors, who want to accelerate their supply chain, cut the cost and friction of customs and excise handling, and move from broker dependency to in-house control.
