The verdict in three sentences
A custom WMS costs between EUR 70,000 and EUR 180,000 in Amsterdam in 2026, versus SaaS licences of EUR 8,000 to 40,000/year rarely fitted to your flows. The return comes from two key figures: +30 % picking productivity and -50 % errors thanks to barcode/RFID scanning and fine location management. For a warehouse of 5,000 to 20,000 SKUs, the investment pays back in 14 to 20 months.
What a custom WMS costs in Amsterdam
Cost depends on the number of modules, the scanning level (barcode or RFID) and ERP integrations. 2026 orders of magnitude.
| Module | Indicative cost (EUR) | Mobile scan | Productivity gain |
|---|---|---|---|
| Stock + locations core | 18,000 - 38,000 | Yes | Reliable base |
| Receiving + control | 10,000 - 22,000 | Barcode | -50 % receiving errors |
| Picking (optimised) | 20,000 - 45,000 | RF terminal | +30 % productivity |
| Shipping + packing | 9,000 - 20,000 | Barcode | Parcel traceability |
| Cycle counting | 7,000 - 16,000 | RF terminal | Real-time stock |
| ERP/accounting integration | 12,000 - 28,000 | - | Automated flows |
Full project delivered in batches over 7 to 12 months, with optimised picking often the highest-ROI module.

Nadia, logistics manager at a distributor in Amsterdam, runs a 12,000-SKU warehouse with 22 pickers. Her picking error rate hits 2.4 %, generating returns and credit notes. She invests EUR 128,000 in a custom WMS (locations, scanned receiving, optimised picking, ERP integration).
Outcome over 14 months: picking productivity climbs 30 %, equivalent to 6 pickers of capacity gained (~EUR 180,000/year valued); errors drop from 2.4 % to 1.2 %, cutting returns and credits by roughly EUR 45,000/year. The WMS amortises in under 12 months on the productivity gain alone.
FAQ
What is the minimum budget for a first WMS? Budget EUR 40,000 to 55,000 for a stock + locations + scanned receiving core, then add optimised picking and integrations.
Barcode or RFID? Barcode covers 90 % of needs at lower cost; RFID (hardware + software surcharge) is justified on high volumes or strict unit-level traceability.
What real productivity gain? Optimised picking (paths, waves, batching) typically delivers +30 % picking productivity and -50 % errors.
Can you connect our ERP? Yes: SAP, Sage, Exact or an in-house ERP integrate natively, with synchronised stock, receiving and shipping.
How long to implement? A first usable batch in 3-4 months; full project in 7 to 12 months depending on modules and number of sites.
