The verdict in three sentences
Market inventory software handles a single warehouse well, but struggles once you run multiple warehouses with transfers, reservations and differentiated pricing. A custom tool (35,000 to 100,000 EUR) gives a unified real-time stock view and reorders calculated on actual demand. The biggest gain isn't on screen: it's the working-capital release through less overstock and fewer stockouts.
Off-the-shelf or custom for multi-warehouse distribution
Generalist ERPs manage stock but handle fine multi-warehouse poorly (cross-reservation, automatic transfers, per-site thresholds). Custom models your exact network.
| Criterion | Standard ERP module | Custom inventory software |
|---|---|---|
| Cost | Included / 10,000-30,000 EUR | 35,000-100,000 EUR |
| Unified multi-warehouse view | Partial | Full real-time |
| Inter-warehouse transfers | Manual | Automated / suggested |
| Reorder thresholds | Global | Per site and seasonality |
| Demand forecasting | Basic | History-based model |
| Pricing / customers | Standard | Multi-tariff, contracts |
| Stockout alerts | Limited | Anticipated, configurable |
A generalist ERP is cheaper to buy but leaves reorder calculation to Excel, where over-investment hides.
Where working capital is won
Stock is immobilized cash. Cutting overstock without creating stockouts is distribution's central equation.
| Lever | Estimated 2026 effect | Financial impact |
|---|---|---|
| Overstock reduction | -12 to -25 % of value | Working capital freed |
| Lower stockout rate | from 5-8 % to 1-2 % | +2 to +4 % revenue |
| Optimized transfers | -30 % emergency buys | Margin preserved |
| Demand forecasting | +15 % reorder accuracy | Less shrinkage |
| Stock turnover | +0.5 to +1.5 turns/year | Cash flow |
*2026 orders of magnitude, depending on sector and product seasonality.*

Mini case study
Karim runs an electrical-supply distributor in Bordeaux: 4 warehouses, 1.8 M EUR permanent stock, stockout rate at 6 %. His custom software at 68,000 EUR unifies the stock view and computes per-warehouse reorders. In 8 months, stock drops 18 % without hurting availability, freeing 324,000 EUR of working capital. At a 6 % financing cost, that's 19,400 EUR annual carrying savings, and lower stockouts add several revenue points. The project pays back in under 18 months on the cash effect alone.
FAQ
Why not just use the ERP's stock module? Because it handles recording but rarely multi-warehouse optimization. Fine reorder calculation, suggested transfers and per-site thresholds are what actually free up working capital.
How does it cut overstock without creating stockouts? It uses consumption history, seasonality and supplier lead times to recommend right-sized quantities per warehouse, with anticipated rather than reactive alerts.
Can we manage per-customer and per-contract pricing? Yes. Custom models your multi-tariff grids, negotiated discounts and framework contracts, which standard modules handle poorly beyond a few levels.
What is the implementation timeline? Plan 3 to 5 months: scoping inter-warehouse flows, migrating history, development, then a warehouse-by-warehouse switch to limit risk.
What concrete ROI to expect? The main lever is working capital: 12 to 25 % less overstock on a 1-2 M EUR stock means 150,000 to 500,000 EUR freed, far above the project cost.
