The verdict in three sentences
A customs brokerage in Amsterdam handling 600 files a month to Germany and Belgium typically leaks 2 to 4% of revenue in disbursements that are never re-invoiced: forgotten terminal storage, demurrage discovered too late, inspection fees paid without a matching charge line. Custom customs brokerage software with container tracking, automatic disbursement control, invoicing and a gateway to Dutch customs systems costs between EUR 70,000 and 150,000 as a 2026 ballpark. For a firm this size, it usually pays for itself in under a year on recovered margin alone.
Where a broker's disbursements disappear
A typical import file through Rotterdam or Schiphol combines a dozen costs advanced on behalf of the client. Each one is a leak when tracking runs on spreadsheets, email and the forwarder's portal.
| Disbursement | Indicative amount per file (2026) | Risk of not re-invoicing |
|---|---|---|
| Terminal storage after free time | EUR 80 to 600 | High, depends on actual release day |
| Container demurrage and detention | EUR 80 to 180 per day | High, billed weeks later |
| Terminal handling and port dues | EUR 150 to 350 | Medium |
| Customs inspection and scanning | EUR 120 to 400 | Medium |
| Import duties and VAT advanced | Variable, often thousands | Medium, cash-flow critical |
| Document fees and certificates | EUR 25 to 90 | Low |
| Late filing penalties | Variable | High |
Across 600 files, missing EUR 60 on one file in three already costs EUR 12,000 a month. The cause is rarely sloppy declarants: the cost information simply reaches the office after the invoice has gone.
Software modules and budget
| Module | Function | 2026 indicative budget |
|---|---|---|
| Files and workflow | Opening, bill of lading, declaration, release, delivery | EUR 15,000 to 30,000 |
| Container tracking | Arrival dates, free time, alerts before demurrage | EUR 10,000 to 20,000 |
| Disbursements | Mobile capture with receipt photo, file matching, pre-invoice check | EUR 10,000 to 20,000 |
| Invoicing and collections | Compliant invoices, client deposits, duty pre-funding | EUR 8,000 to 15,000 |
| Customs gateway | Import of declaration data and statuses from Dutch customs systems | EUR 15,000 to 35,000 |
| Client portal | Real-time tracking for importers in Germany and Belgium | EUR 6,000 to 15,000 |
| Migration, testing, training | Open files imported, declarant training | EUR 6,000 to 15,000 |
The most profitable rule is simple: no invoice can be issued until the file's disbursements are closed. The software compares recorded costs with the items expected for that flow and blocks the invoice if storage or inspection is missing.
Then plan EUR 1,200 to 3,000 a month as a 2026 ballpark for hosting, backups and maintenance, depending on the support level required.
Before and after: the metrics that move
| Metric | Spreadsheets and email | Brokerage software |
|---|---|---|
| Disbursements not re-invoiced | 2 to 4% of revenue | Under 0.5% of revenue |
| Delay from release to invoice | 7 to 20 days | 24 to 48 hours |
| Avoidable demurrage | 10 to 20 containers a month | 2 to 5 containers a month |
| Time to find a file | 10 to 30 minutes | Under a minute |
| "Where is my container?" calls | 40 to 80 a day | Cut by 3 with the portal |
| Average client payment delay | 45 to 60 days | 30 to 40 days |
Fast invoicing matters as much as recovering disbursements: an invoice sent the day after release is paid sooner, and the duties pre-funded for the client come back earlier.

Joost runs a customs brokerage in Amsterdam: 600 files a month, EUR 6 million in annual revenue, unbilled disbursements estimated at 3%, so EUR 180,000 a year. He chooses software at EUR 110,000 with maintenance at EUR 2,000 a month (EUR 24,000 a year).
Checking disbursements before invoicing recovers 80% of the leakage: EUR 144,000. Free-time alerts avoid 2 days of demurrage on 15 containers a month at EUR 120 a day: EUR 3,600 a month, so EUR 43,200 a year. Net annual gain: 144,000 + 43,200 - 24,000 = EUR 163,200. Payback in about 8 months.
FAQ
Can the software connect to Dutch customs systems?
It can exchange declaration data and statuses through certified software providers or the interfaces available to your licensed brokerage. Plan EUR 15,000 to 35,000 for this gateway, with 3 to 4 weeks of testing.
How long does the project take?
Between 4 and 6 months as a ballpark: 3 weeks of scoping with your declarants, 3 to 4 months of modular development, 1 month of acceptance on live files.
How are costs paid at the terminal captured?
From a mobile app: the driver or clerk photographs the receipt, picks the file and the amount in under a minute. A disbursement without proof stays flagged on the finance dashboard.
Can clients in Germany and Belgium track their files?
Yes, through a secure client portal showing steps, documents and invoices. This module costs EUR 6,000 to 15,000 and sharply reduces tracking calls.
Is the data GDPR compliant?
Hosting stays in the EU with daily backups, encryption and access logs. Each client contract includes a data processing annex, prepared in 1 to 2 weeks.
