The verdict in three sentences
A hardware store managing thousands of SKUs from memory suffers 8 to 12 % of lost sales to stockouts and does not know its real margin per item. A SKU-catalogue, multi-warehouse stock, counter-sale mobile money and supplier reordering app cuts stockouts by about 25 % and reveals profitability item by item. In Dar es Salaam, the tool pays off in 4 to 7 months by capturing sales once lost.
Stockouts and the invisible margin
Without a system, the manager does not know how many screws, pipes or cement bags are really left. The result: stockouts on fast movers and dead money tied up on the rest.
| Indicator | Without app | With 2026 app |
|---|---|---|
| Stockout rate on best-sellers | 8-12 % | 3-6 % |
| Physical/theoretical inventory gap | 15-20 % | < 4 % |
| Time for a full inventory | 2-3 days | 3-4 hours |
| SKUs tracked accurately | ~200 from memory | unlimited |
| Margin known per item | no | yes, real time |
| Capital tied in overstock | high | -18 % |
Knowing the real margin per SKU lets you stop selling poorly negotiated items at a loss and push the ones that pay.
The hardware modules that pay
| Module | What it does | 2026 gain |
|---|---|---|
| SKU catalogue | Code, price, margin, location | instant search |
| Multi-warehouse stock | Tracking per store/warehouse | -25 % stockouts |
| Counter sales | Receipt, mobile money payment | traced collection |
| Supplier reordering | Threshold alerts, purchase orders | -18 % dead capital |
| Margin per item | Purchase cost vs sale price | +6 pts margin |
| Dashboard | Top sellers, slow movers | data decisions |
As a 2026 order of magnitude, a hardware store app sits between 1,100,000 and 2,400,000 FCFA, with maintenance of 45,000 to 140,000 FCFA/month.
Mini case study
Sekou runs a hardware store in Dar es Salaam selling 9,000,000 FCFA/month. He loses 10 % of sales to stockouts, i.e. 900,000 FCFA/month going to the competitor. With multi-warehouse stock and automatic reordering, his stockouts fall to 5 %, recovering 450,000 FCFA/month of sales. On top, margin visibility earns him 6 points on part of the catalogue. The 1,700,000 FCFA app pays for itself in about 4 months on avoided stockouts alone.
