The verdict in three sentences
In Amsterdam in 2026, a SaaS WMS costs EUR 40-150 per user per month while a custom build runs between EUR 70,000 and 180,000. Custom becomes worthwhile once your processes (wave picking, cross-docking, multi-depot) fall outside market standards. Budget 5 to 9 months, 99% stock accuracy and -30% picking errors.
What drives a WMS price
A WMS controls locations, movements and order picking in real time. Price mainly depends on the number of flows to model, mobility (terminals, scanning) and the depth of integration with ERP and TMS.
| Criterion | SaaS WMS | Custom WMS |
|---|---|---|
| Entry ticket | EUR 40-150/user/month | EUR 70,000-180,000 |
| Go-live | 6-12 weeks | 5-9 months |
| Picking strategies | Predefined | Your real waves |
| Multi-depot | Vendor-dependent | Unlimited |
| 3-year cost (15 users) | ~EUR 90,000-120,000 | EUR 90,000-210,000 |
| Scanning & terminals | Add-on | Natively integrated |
| Code ownership | No | Yes |
WMS modules and 2026 budgets
The core (receiving, locations, picking, shipping) is a must. Barcode scanning and ERP integration are the two investments that unlock the most value.
| Module | 2026 range (EUR) | Main gain |
|---|---|---|
| WMS core (receiving, picking, shipping) | 40,000-80,000 | Stock accuracy |
| Barcode / RF scanning | +10,000-25,000 | -30% errors |
| ERP integration | +8,000-22,000 | No double entry |
| Multi-depot management | +12,000-30,000 | Global view |
| Slotting optimisation | +8,000-20,000 | Picking productivity |
| Shipment portal & tracking | +6,000-18,000 | Traceability |
