What we do

We specialise in customs, excise, and international trade software solutions and services. With our team of experts, we develop, commercialise, and operate CAS, a global trade management solution for enterprises that want to centralise and automate their customs and trade compliance processes. CAS enables enterprises to run a global digital customs competence centre that reduces administrative and duty costs while keeping up with the ever-changing complexities of customs and trade regulations. In tandem with our expert advisory services, CAS helps organisations go beyond compliance to make customs and trade a strategic component of their growth.


Our story

During a white night, inspired by Blown to Bits: How the New Economics of Information Transforms Strategy, I dreamt about transforming customs services into a combination of expertise, legal content, and technology.

From that day onwards, I started to seek allies, and in 2004 I founded C4T. We began as a consultancy, however the goal was to move beyond providing guidance to developing a technology solution that could tackle the complexities of customs head on. I set out to assemble a unique team of customs experts and best-of-breed technology engineers to create CAS, a one-of-a-kind software solution that automates customs and trade compliance. Our team of experts and developers have been working together ever since to forge digital tools that apply customs and legal expertise to automate compliance. We have created a team with a great "can do" attitude and drive to get the job done, providing clients with continual updates and feature enhancements.

Today, CAS is composed of several modules to be used in combination or as a stand-alone solution and can be fully integrated with SAP or other ERP/WMS systems. Our core Declarations functionality supports zero-touch filing in the UK, Belgium, the Netherlands, France, Switzerland, and Ireland with more countries to follow. To date we have introduced our Special Procedures module that manages Inward Processing (IPR), Customs Warehousing, End-Use and Outward Processing (OPR); our visibility and analytics module, Insights; and our Configuration Model including Decision Tables, with our Origin Management model in full development.

With CAS, our clients experience faster time to market, reduce customs duty and administration costs, and gain strategic visibility into their customs operations. We are committed to shifting the role of customs organisations from cost centre to strategic player and continue to define the future of customs. Our story is far from finished.
