The verdict in three sentences
A grain terminal in Rotterdam cannot switch silo software during the post harvest peak, so a realistic project starts 9 to 12 months before the target go live window. The schedule for a terminal with several silo blocks, truck and barge weighbridges and transshipment flows runs 7 to 11 months: 4 to 6 weeks of discovery, 16 to 26 weeks of build and 6 to 10 weeks of weighbridge, laboratory and customs integration testing. The most common delay is not code but customs and port community system integration, which depends on third party test environments.
The schedule phase by phase
| Phase | Realistic duration (2026 estimate) | Deliverable | Gate to move on |
|---|---|---|---|
| Discovery and site walk | 4 to 6 weeks | Requirements, interface inventory | Commodity, quality and stock rules signed off |
| Design and prototypes | 3 to 4 weeks | Weighing, sampling and stock screens | Validated by operations and lab leads |
| Core build (intake, weighing, silo stock) | 12 to 18 weeks | Internal test release | Acceptance on test data passed |
| Quality sampling and lab results | 4 to 6 weeks, in parallel | Sample records linked to lots and cells | Lab workflow approved |
| Customs and port data exchange | 6 to 10 weeks, in parallel | Declarations data exported, status received | Successful runs in partner test environments |
| Weighbridge integration and field tests | 4 to 6 weeks | Automatic weight capture on all bridges | 300 test weighings without discrepancy |
| Pilot and cutover | 4 to 6 weeks | Live operation on one flow, then all | Under 0.5 % exceptions |
With parallel work, the total is 7 to 11 months. For a September peak, cutover should be done by June at the latest.
What the system covers
Truck, rail and barge intake, gross and tare weights, moisture and admixture sampling, lot allocation to silo cells, blending, drying, outbound vessel and barge loading, stock reconciliation, and data exchange with customs and port partners for transshipment cargo. EU food and feed traceability rules mean every lot must be traceable one step back and one step forward.
Budget and causes of delay
| Item | 2026 market ballpark |
|---|---|
| Discovery and design | 25,000 to 70,000 EUR |
| Core build: intake, weighing, silo stock | 120,000 to 450,000 EUR |
| Quality sampling and lab integration | 25,000 to 90,000 EUR |
| Customs and port data exchange | 40,000 to 150,000 EUR |
| Weighbridge interfaces and hardware | 20,000 to 80,000 EUR |
| Staff onboarding and pilot | 10,000 to 40,000 EUR |
| Support after go live | 4,000 to 15,000 EUR a month |
Kolonell is one nearshore option for well bounded modules (operator dashboards, sampling app, supplier portal). Kolonell's prices for custom applications are 6,100 to 10,670 EUR for medium complexity and 10,670 to 22,870 EUR and above for complex builds (4,000,000 to 15,000,000 FCFA and above), with maintenance at 53, 114 or 183 EUR a month. A full terminal system with customs integration is a larger engagement priced after discovery.
| Cause of delay | Typical slip | How to avoid it |
|---|---|---|
| Customs or port partner test environment not available | 3 to 8 weeks | Book test slots during discovery |
| Legacy weighbridge indicators without data output | 2 to 6 weeks | Inventory in week 1, order interfaces early |
| Quality and blending rules not agreed | 2 to 4 weeks | Written sign off before build |
| Master data (cells, grades, customers) inconsistent | 2 to 4 weeks | Clean up in parallel with build |
| Cutover during peak season | Season lost | Hard cutover deadline 6 weeks before peak |
| Key users unavailable for testing | 2 to 3 weeks | Block test days in the operations calendar |
Mini case study
Illustrative example, fictional terminal: Sanne, operations director of a grain terminal in Rotterdam, 4 weighbridges, 60 silo cells, 1.2 million tonnes a year. Today, weights and lab results are re keyed into two systems, taking 3 clerks full time, and stock discrepancies trigger about 6 days of reconciliation per quarter.

With a 520,000 EUR project and 9,000 EUR monthly support, she redeploys 2 clerks at 55,000 EUR each a year, saving 110,000 EUR a year, and cuts reconciliation to 1 day per quarter. Faster barge turnaround of even 2 hours on 400 calls a year adds further savings on demurrage, bringing payback to around 3 to 4 years.
FAQ
How long does grain terminal software take in Rotterdam in 2026?
Plan 7 to 11 months from discovery to full cutover, including a 4 to 6 week pilot. Starting less than 6 months before peak usually pushes go live to the next season.
What budget should we plan?
The 2026 market ballpark is 250,000 to 900,000 EUR, plus 4,000 to 15,000 EUR a month in support. Customs and port integration alone can account for 40,000 to 150,000 EUR.
Can any weighbridge be connected?
Most modern indicators offer serial or network output; older ones need an interface module or replacement. Run at least 300 test weighings per bridge before go live.
Why is customs integration the usual bottleneck?
It depends on partner test environments and certification steps outside your control. Book test slots during discovery and allow 6 to 10 weeks.
How do we protect operations during cutover?
Keep the old system read only for at least 4 weeks and define a manual fallback for weighing. Cut over one flow first, typically truck intake, then the rest.
