The verdict in three sentences
A retail business run on a notebook or an Excel file never knows, at any given moment, what it truly has on the shelf: it suffers stock-outs on fast movers and lets capital sleep on slow movers. A real-time inventory management app turns every stock-in and stock-out into usable data, with a reorder-point alert, barcode stocktaking and instant stock valuation. Budget a 2026 order of magnitude of 600,000 to 1,200,000 FCFA and 6 to 10 weeks for a multi-store tool wired to your accounting.
Notebook / Excel versus real-time inventory app
An Excel file doesn't lie: it forgets. Every unrecorded sale, every delivery jotted on scrap paper widens the gap between theoretical and real stock. Here is what a dedicated business app changes.
| Criterion | Notebook / Excel | Real-time inventory app |
|---|---|---|
| Stock update | Manual, end of day | Automatic on every sale |
| Stock-out alert | None | Configurable reorder point |
| Physical stocktake | 1-2 days, shop closed | Barcode scan, a few hours |
| Stock valuation | Rough manual estimate | Instant (WAC or FIFO) |
| Multi-store | Separate, unconsolidated files | Consolidated real-time view |
| Data reliability | 60-70 % | 95-98 % |
What you gain, in numbers
A shop's two money leaks are invisible in a notebook: the sale lost for lack of stock, and the cash frozen on dead items. The app makes both measurable and manageable.
| Indicator | Before (notebook/Excel) | After app | Effect |
|---|---|---|---|
| Stock-out rate | 18-22 % | 13-16 % | -25 % stock-outs |
| Dead stock (> 90 days) | 30 % of stock | 25 % of stock | -15 % frozen capital |
| Stocktake duration | 1-2 days | 3-4 hours | Shop stays open |
| Inventory variance | 8-12 % | 2-3 % | Theft/error detected |
| Project cost (2026 order of magnitude) | — | 600,000 - 1,200,000 FCFA | 6-10 week lead time |
An accounting export module (SYSCOHADA) and consolidated multi-store management sit at the upper end of the budget.

Mini case study
Awa runs a cosmetics shop in Dakar, monthly revenue 4,000,000 FCFA, margin 35 %. Before the app she lost roughly 20 % of potential sales to stock-outs — 800,000 FCFA of missed revenue per month and 280,000 FCFA of vanished margin. With reorder alerts she recovers a quarter of those sales: 70,000 FCFA of margin per month, or 840,000 FCFA over the year. The app, bought for 800,000 FCFA, pays back in under 12 months — not counting the capital freed by lower dead stock.
FAQ
Do I need a physical barcode scanner? No, a smartphone is enough: the app scans barcodes through the camera. A USB scanner (25,000 - 45,000 FCFA order of magnitude) just speeds up stocktaking in larger shops.
Does the app work offline? Yes, it is built for 3G and outages: sales are stored locally then synced as soon as the network returns. No sale is lost.
Can I manage several shops? Yes, the multi-store view consolidates stock in real time and enables inter-store transfers. This feature sits in the 900,000 - 1,200,000 FCFA tier.
How long until it is operational? Count 6 to 10 weeks: 2 weeks of scoping and catalogue import, 4 to 6 weeks of development, 1 to 2 weeks of training and in-shop run-in.
