The verdict in three sentences
For a customs broker in Antwerp handling 4,500 declarations a year, running files on Excel and WhatsApp leaks margin in two specific places: container demurrage and disbursements forgotten at invoicing. Custom freight and customs software costs EUR 23,000 to 46,000 (15 to 30 million FCFA in our West African projects), plus about EUR 7,600 for the customs single window interface, and ships in 5 months. International packages exist, but they are expensive per seat and rarely fit a mid-sized broker's billing logic.
What Excel and WhatsApp really cost
| Margin leak (2026 ballpark, 4,500 files/year) | Frequency | Estimated annual cost |
|---|---|---|
| Avoidable demurrage (40ft container, EUR 40 to 90/day) | 8% of files, 4 days on average | EUR 76,000 |
| Unbilled disbursements (storage, scanning, escort) | 6% of files, EUR 70 | EUR 18,500 |
| Late invoicing (collection at 75 days) | All files | EUR 137,000 tied up in working capital |
| Double data entry (Excel then customs system) | 25 minutes per file | 1,875 hours a year |
| Client calls and messages "where is my container?" | 6 per file | 27,000 exchanges a year |
| Declaration errors and penalties | 1% of files | EUR 6,000 to 12,000 |
Demurrage, paid to the shipping line or terminal, is the largest item. It is avoidable when an alert warns the team three days before free time ends.
Scope of custom freight and customs software
| Module | 2026 budget | Lead time |
|---|---|---|
| Import and export files (B/L, containers, documents, statuses) | EUR 6,100 to 10,700 | 6 weeks |
| Container tracking and free time alerts (demurrage) | EUR 3,800 to 7,600 | 4 weeks |
| Fee and disbursement invoicing, client advances | EUR 4,600 to 9,100 | 4 weeks |
| Importer portal (online tracking, documents, invoices) | EUR 4,600 to 9,900 | 4 weeks |
| Automated WhatsApp and SMS notifications | EUR 1,500 to 3,800 | 2 weeks |
| Dashboards (margin per file, lead times, clients) | EUR 2,300 to 4,600 | 2 weeks |
| Subtotal | EUR 23,000 to 46,000 | 5 months |
| Customs single window interface | +EUR 7,600 | in parallel |
Hosting, backups and maintenance: EUR 380 to 900 per month. Clients can pay by bank transfer or card straight from the portal (and via Wave or Orange Money for West African importers).
Conditions for success
The project succeeds when the head of operations and accounts team join scoping from week one. Migration of open files (often 300 to 500) must be planned before go-live. Finally, the single window interface depends on technical access tied to the broker's licence, so the request should be filed in month one.
Mini case study
Pieter, director of a customs brokerage near the port of Antwerp, records 360 files a year with demurrage, averaging 4 days at EUR 53 per day, or EUR 76,300. With free time alerts, he targets a 60% reduction, saving EUR 45,800. Add EUR 13,700 of disbursements now billed. The full project costs EUR 41,000 including the single window interface, plus EUR 8,200 annual maintenance: payback in about 9 months, before counting the cash gain from invoicing on delivery day.

FAQ
Wouldn't an international package be cheaper?
International licences run about EUR 230 to 460 per user per month, or EUR 27,000 to 55,000 a year for 10 users. They often handle local disbursements and custom billing poorly.
How quickly can we start?
Allow 5 months in total, with a first version (files, containers, alerts) usable from month three. Invoicing and the portal follow in months four and five.
Can our clients pay online?
Yes, the portal accepts card and transfer, plus Wave and Orange Money for African clients, at 1 to 2% fees depending on the method. Disbursement advances are collected before the vessel arrives.
What happens to our Excel data?
The last 2 to 3 years are migrated, usually for EUR 760 to 1,500. That lets you compare client margins immediately.
Does it work for multiple ports, such as Rotterdam or Zeebrugge?
Yes, it handles several offices and ports. Adding a site typically costs EUR 2,300 to 4,600 depending on local specifics.
