What Our Clients Say

Carmen Wallays Supply Chain Director - Agristo

"Automating customs operations created efficiency in administration and continuity in logistics, for example allowing us to load 24/7. This likely has given us a competitive advantage."

Sophie Lavis UKI Customs Team Lead - Flora Food Group

"With CAS, the average turnaround time for a declaration, from the SAP trigger to the export and even import of goods, is about 22 minutes – this is 65 times faster! CAS is not only a huge time-saver. Over the years, using CAS, our costs have dropped massively. By replacing the use of customs brokers with the CAS system, we realise 46% cost savings every year."

Christof Van Roey Credit Manager - Reynaers Aluminium

"Since everything is triggered automatically from our ERP system, creating a declaration takes only one minute. Next, to release the declaration in CAS takes about another minute, and that is it. While working with brokers in the past, completing the end-to-end customs declaration process would take a very long time. The efficiency of CAS has changed our processes for the better."

Claire Hoflack Executive Team Member - Ecofrost

"Declaration times have been cut by more than 50%, dropping from around 30 minutes per shipment to as little as 10 minutes. In some cases, declarations are completed in under five minutes."

Alexandre Dumont de Chassart Director of Operations Europe - Yakima Chief

"Automating our customs declarations has helped us expedite import, export, and transit between the EU and UK as well as incoming shipments from the US to our warehouse in Belgium."

Richard Towens Compliance and Project Accountant - Smart Garden Products

"Being able to do our own declarations instead of outsourcing them brings clear cost benefits, but another big advantage is the control we now have. CAS houses everything in one system, combining declarations and customs warehousing, so the flows run seamlessly. We rarely see issues, and when we do, it’s clear where to resolve them."

Olenex

"CAS took over the manual work, often the more repetitive and tedious tasks, it freed up time to focus on other aspects of customs operations, such as compliance and reporting. Thanks to the automation in CAS, we have shifted from a reactive to a proactive approach in managing customs processes."

Transform your supply chain by optimising and automating your customs operations with trade compliance software.
