The verdict in three sentences
A custom multi-warehouse WMS (inbound/outbound, cycle counting, barcodes, reorder thresholds) runs between 8M and 25M FCFA (12,000-38,000 EUR) depending on the number of warehouses and scanning hardware. Barcode scanning cuts picking errors by roughly 60 % and lifts stock accuracy to 98 % or more. As soon as you run 2 or more warehouses with transfers, spreadsheets hit their limit and the WMS pays back in 12 to 20 months.
Scope and budget of a multi-warehouse WMS
Budget depends on the number of warehouses, SKU volume and hardware. Here are the blocks and their 2026 order of magnitude.
| Module | Scope | Indicative cost (FCFA) | Cost (EUR) |
|---|---|---|---|
| Inbound / outbound | Receiving, shipping, slips | 2M - 4M | 3,000 - 6,100 |
| Barcode & scanning | Scanners, labels, mobile | 2M - 5M | 3,000 - 7,600 |
| Cycle counting | Cyclical counts, variances | 1.5M - 4M | 2,300 - 6,100 |
| Inter-warehouse transfers | Transfer orders, in-transit | 2M - 5M | 3,000 - 7,600 |
| Thresholds & reorder alerts | Min/max, purchase suggestions | 1.5M - 4M | 2,300 - 6,100 |
| Multi-warehouse reporting | Valuation, turnover, dashboard | 2M - 5M | 3,000 - 7,600 |
A 2-3 warehouse WMS with scanning lands around 12M-18M FCFA; a 4+ warehouse rollout with transfers and advanced reporting climbs toward 20M-25M FCFA.
The measured logistics impact
Stock errors cost through stockouts, overstock and customer disputes. Order of magnitude observed at a 3-warehouse distributor.
| Metric | Before | After WMS | Effect |
|---|---|---|---|
| Stock accuracy | 84 % | 98 % | +14 pts |
| Picking errors | 5.2 % | 2.1 % | -60 % |
| Inventory count time | 3 days | 4 h | -85 % |
| Avoidable stockouts | 11 %/month | 3 %/month | -8 pts |
| Tied-up overstock | 22 % | 13 % | -9 pts |
| Inter-warehouse transfer time | 2 days | 6 h | -75 % |

Mini case study
Omar, logistics director at a spare-parts distributor in Toronto (3 warehouses, 14,000 SKUs). He invests 16M FCFA (24,000 EUR) in a custom WMS with mobile scanning, cycle counting and inter-warehouse transfers. Stock accuracy rises from 84 to 98 %. On tied-up stock of 320M FCFA, cutting overstock by 9 points frees nearly 29M FCFA of cash; adding lower stockouts and disputes, the project pays back in under 14 months.
FAQ
Do we need special hardware? Handheld scanners or plain Android smartphones with the scan app are enough (30,000-120,000 FCFA each). Barcode labels print on site. The WMS works without heavy investment.
How do we handle warehouses with poor connectivity? Offline mode records movements locally and syncs once the network returns. It is essential for peripheral warehouses.
Does cycle counting replace the annual count? It makes it reliable and lighter: by counting a subset each day, you catch variances continuously. Many firms reduce the annual count to a simple verification.
Can we connect accounting or the ERP? Yes, via API or export: stock valuation, movements and purchases sync. Budget 2M-5M FCFA depending on the target system.
How long to deploy? 2 to 4 months: start with a pilot warehouse, tune the scan process, then replicate. Each additional warehouse is added in 2-3 weeks.
