The verdict in three sentences
A custom WMS in Amsterdam runs between 55,000 and 130,000 EUR in 2026, depending on the number of locations and integrations. The main gain is inventory accuracy lifted to 99.5% and higher picking productivity through barcode terminals. The timeline is 6 to 9 months, ERP integration included.
The WMS budget breakdown
A WMS drives receiving, put-away, location management, order picking, stock counts and shipping. Here is the typical module split in 2026.
| Module | 2026 range (EUR) | Indicative timeline |
|---|---|---|
| Core WMS (receiving, stock, shipping) | 35,000 - 70,000 | 3 - 5 months |
| Fine location management | 10,000 | 4 - 6 weeks |
| Barcode / scan terminals | 8,000 | 3 - 5 weeks |
| ERP integration | 12,000 | 5 - 7 weeks |
| Picking path optimization | 9,000 | 4 - 6 weeks |
| Cycle counting | 6,000 | 3 - 4 weeks |
| Logistics dashboards | 5,000 | 2 - 3 weeks |
A single-site warehouse starts around 60,000 - 70,000 EUR (core, locations, scan). A multi-flow site with ERP and picking optimization reaches 120,000 - 130,000 EUR.
What inventory accuracy changes
Moving from 95% to 99.5% accuracy removes hours of searching, phantom stockouts and wrong shipments. Here is the typical 2026 impact on an SME warehouse.
| Indicator | Before WMS | After WMS |
|---|---|---|
| Inventory accuracy | 94 - 96% | 99.5% |
| Lines picked / hour | 40 - 55 | 65 - 85 |
| Picking errors | 1.5 - 2.5% | < 0.4% |
| Annual stock-count time | 3 - 5 days | 1 - 2 days |
| Damage / loss rate | 1.2% | < 0.5% |
Mini case study
Mark, logistics director of a distribution SME in Amsterdam, runs a warehouse picking 1,400 lines/day with 6 pickers. Moving from 48 to 72 lines/hour with the WMS and scanning, each picker handles the equivalent of 1.5 shifts of useful time. At a loaded cost of 2,600 EUR/month per picker, the company absorbs growth without hiring 2 people, saving 62,400 EUR/year. The WMS investment of 68,000 EUR pays back in a little over a year, before counting fewer shipping errors.

What is the minimum budget for a WMS in Amsterdam in 2026?
Around 55,000 to 70,000 EUR for a single-site warehouse with core, location management and barcode scanning. That scope delivers the fastest accuracy gain.
Do we need specific barcode terminals?
Rugged Android terminals are often enough; the 8,000 EUR software budget covers the scan app, not the hardware. Budget 300 to 700 EUR per terminal depending on ruggedness.
Does the WMS integrate with my existing ERP?
Yes, via a 12,000 EUR integration covering items, stock and orders. It is the item to secure first to avoid double entry.
How long until 99.5% accuracy?
Usually 2 to 3 months after go-live, the time to clean up locations and train teams. It is a 2026 estimate depending on the initial stock condition.
Can we manage several warehouses?
Yes, the core supports multi-site; each extra site mainly adds configuration and integration, not a full rebuild.
