The verdict in three sentences
For a customs broker in Rotterdam or Amsterdam handling 600 files a month, the real cost is not the software but unplanned demurrage and detention and disbursements forgotten at invoicing. Custom brokerage software costs between EUR 27,000 and 61,000 in 2026 (about 18 to 40 million FCFA), with a 6-month phased delivery. The project pays off as soon as you lose more than EUR 2,300 a month on container penalties, unbilled disbursements and re-keying between your declaration system and Excel.
What each option costs in 2026
Dutch brokers have three routes: stay on Excel and email, buy an off-the-shelf brokerage suite and bend your processes to it, or build a tool wired into your own workflows, your declaration software and port community data such as Portbase. The figures below are 2026 orders of magnitude for a team of 25 to 40 declarants and tracking agents (excluding VAT).
| Option | Upfront cost | Annual recurring cost | Time to go live | Fit with your procedures |
|---|---|---|---|---|
| Excel + email + folders | EUR 0 | EUR 0 (but lost hours) | Immediate | Low, no alerts |
| Off-the-shelf brokerage suite (licences) | EUR 9,000 to 18,000 | EUR 12,000 to 23,000 | 3 to 5 months | Medium, limited configuration |
| Custom software, core scope | EUR 27,000 to 38,000 | EUR 3,800 to 6,100 | 4 to 5 months | Strong |
| Full custom software (client portal, APIs) | EUR 43,000 to 61,000 | EUR 6,100 to 9,900 | 6 months | Complete |
| Hybrid: suite + custom modules | EUR 18,000 to 30,000 | EUR 14,000 to 21,000 | 4 to 6 months | Good, double maintenance |
| Ongoing evolutive maintenance only | EUR 0 | EUR 460 to 920 per month | Continuous | Per contract |
The off-the-shelf suite looks cheaper at first, but per-user licences and configuration fees push the three-year cost up. Custom software flips the curve: a heavier upfront investment, then low recurring costs and full ownership of the code.
The modules that drive return on investment
Useful brokerage software does more than store files. It must track every container from arrival notice to empty return, and trigger the right alerts before free time expires.
| Module | Key function | Indicative 2026 budget | Measurable gain |
|---|---|---|---|
| File and document management | Bills of lading, invoices, certificates of origin, declarations centralised | EUR 5,300 to 9,100 | 40% less time spent searching |
| Container tracking | Vessel, terminal, release, empty return status | EUR 4,600 to 10,700 | Real-time visibility |
| Demurrage alerts | Free-day countdown, alerts at D-3 and D-1 | EUR 3,000 to 6,100 | Up to EUR 115 per container per day avoided |
| Disbursement invoicing | Duties, taxes, handling fees re-billed automatically | EUR 4,600 to 9,900 | 2 to 4% of disbursements recovered |
| Declaration system interface | Import of statuses and references, less re-keying | EUR 3,800 to 9,100 | 1 to 2 hours per declarant per day |
| Client portal and WhatsApp or email notifications | Online tracking for importers | EUR 3,000 to 8,400 | 50% fewer inbound calls |
| Management dashboards | Margin per file, average lead times, receivables | EUR 2,300 to 5,300 | Weekly steering |
The demurrage alert module is often the first to pay for itself. Beyond the free period granted by the carrier or terminal, penalties climb in tiers and reach around EUR 115 per day for a 40-foot container in some contracts. Across 600 files a month, a handful of delays is enough to wipe out the month's margin.
Typical 6-month plan
Delivery happens in batches so your team uses the tool from month three. Month 1: scoping, mapping procedures and declaration flows. Months 2 and 3: files, documents and container tracking. Month 4: alerts and disbursement invoicing. Month 5: client portal and dashboards. Month 6: historical data migration, training and stabilisation. Each batch is tested on live files before rollout.

Sarah, operations director at a customs broker in Rotterdam, handles 600 files a month. She estimates that 4% of containers exceed their free time by 3 days on average, so 24 containers a month. At EUR 90 per day on average, the bill reaches 24 x 3 x 90 = EUR 6,480 a month, half of which cannot be passed on to clients. On top of that, about EUR 1,370 of disbursements slip through each month. With custom software at EUR 40,000 that cuts overruns by 70% and recovers 80% of disbursements, the monthly gain is around 2,270 + 1,100 = EUR 3,370. Payback arrives in roughly 12 months, before counting the re-keying hours saved.
FAQ
Can the software connect directly to the customs declaration system?
It depends on the APIs exposed by your declaration software and on Portbase access. Most projects start with structured import of references and statuses, which already removes 1 to 2 hours of re-keying per declarant per day.
How soon will we see the first gains?
Container tracking and demurrage alerts ship around month three or four. The first containers saved from penalties show up within weeks of use, at EUR 90 to 115 per day avoided.
Who owns the code?
In a Kolonell custom project, the source code and data belong to you. You can hand maintenance to another provider, and recurring costs stay limited to hosting and maintenance, EUR 3,800 to 9,900 a year.
Does it work on mobile at the terminal?
Yes, the web app is built mobile-first with lightweight screens for agents on the quay. Data entered offline syncs as soon as the network returns.
Can we start with a smaller scope?
Yes. A first batch covering files, containers and alerts costs around EUR 27,000 and ships in 4 months. Disbursement invoicing and the client portal are added later without a rebuild.
