The verdict in three sentences
A custom WMS (Warehouse Management System) in Toronto costs between 35,000 and 100,000 EUR HT in 2026 depending on floor area, number of SKUs and the level of scan automation. It pays off once your warehouse passes 2,000 SKUs and picking errors generate returns and customer disputes. The ROI comes from picking errors cut by three, accelerated inventory and better space utilization.
What a WMS structures
A WMS replaces paper picking and forklift-operator memory with a logic of locations and scanning. Every product has an address, every move is traced, every pick is guided.
| Function | Without WMS | With WMS |
|---|---|---|
| Product locations | Memory, paper | Precise addressing |
| Order picking | Manual picking | Optimized path + scan |
| Picking error rate | 2 to 4% | 0.3 to 0.8% |
| Inventory | Full 2-3 day shutdown | Cycle counting |
| Receiving | Delayed entry | Scan-time check |
| Lot/expiry traceability | Fragile | Complete |

Mini case study
Thomas, supply chain manager of a materials wholesaler in Toronto. His warehouse picks 1,500 order lines per day with a 3% error rate, i.e. 45 daily errors. Each error costs an average of 32 EUR (return, re-shipment, goodwill gesture), or 1,440 EUR/day.
A WMS with mobile scanning brings the error rate down to 0.6%, i.e. 9 errors/day (288 EUR). The saving reaches 1,152 EUR/day, about 253,000 EUR/year over 220 working days. Adding cycle counting that removes 3 days of annual shutdown, the payback on a 70,000 EUR HT investment lands in under 4 months.

Is a WMS worth it for a medium warehouse?
Yes from 2,000 to 3,000 SKUs or as soon as picking errors become recurring. Below that, a simple stock module in your ERP may suffice. The threshold is judged on the real cost of errors, not on floor area.
Do we need specific hardware?
Scanning terminals (handheld scanners or Android PDAs) at 300-600 EUR each, plus location labels. The software runs on this standard hardware, with no heavy investment in conveyors needed.
How long does warehouse rollout take?
Development takes 4 to 7 months, but physical rollout (addressing, labelling, training) adds 2 to 4 weeks. Starting on a pilot zone limits the risk.
Does the WMS connect to our ERP?
Yes, ERP integration (incoming orders, stock, invoicing) runs 12,000 to 25,000 EUR HT depending on the ERP. It is key to avoid double entry and keep stock reliable in real time.
Can it manage expiry dates and lots?
Yes, lot and expiry traceability (FEFO) is a standard module, essential in food and perishable materials. Budget 8,000 to 15,000 EUR HT for full traceability.
