The verdict in three sentences
Untracked shrinkage eats 2 to 5 % of a shop's revenue, and stockouts push roughly 4 % of potential sales to the competitor next door. A notebook detects none of it: it doesn't count, it doesn't alert, and it never tells you which product is sleeping on your shelf. A barcode inventory app at 3,000-9,000 FCFA/month pays for itself in weeks and unlocks 15 to 25 % of capital frozen in dead stock.
Notebook vs app: what every column changes
The notebook and memory feel free. They cost you in invisible stockouts, in overstock that freezes cash, and in theft nobody notices until the yearly count.
| Criterion | Notebook / memory | Inventory app |
|---|---|---|
| Monthly cost | 0 FCFA on paper | 3,000-9,000 FCFA |
| Shrinkage tracked | No (2-5 % of sales lost) | Yes, counted vs sold |
| Physical stock-take | 3-6 hours | 20-40 minutes by scan |
| Reorder-point alert | None | Automatic per SKU |
| Stockouts | ~4 % of revenue lost | Cut by about 50 % |
| Top products identified | No | Yes, sales analytics |
| Capital in dead stock | 15-25 % | Tracked and reduced |
| Supplier reordering | Manual, forgotten | Suggested, semi-automated |
The payback math in plain terms
For a shop turning over 4,000,000 FCFA per month, every lever matters. Here is the 2026 order-of-magnitude for the gains recoverable in the first year.
| Item | Estimated loss/month | Gain with the app |
|---|---|---|
| Shrinkage (3 %) | 120,000 FCFA | 60-90,000 FCFA recovered |
| Stockouts (4 %) | 160,000 FCFA | ~80,000 FCFA regained |
| Overstock tied up | 700,000 FCFA capital | 300,000 FCFA freed |
| Stock-take time | 5 h x 4 people | down to 40 min |
| App cost | — | 6,000 FCFA/month |
A monthly gain in the order of 150,000 to 200,000 FCFA against a 6,000 FCFA cost: the return is measured in weeks, not years.

Mini case study
Ama runs a cosmetics and accessories shop in Accra, about 350 SKUs and 3,800,000 FCFA in monthly sales. Before the app she recounted stock every quarter over half a day and each time found 90,000 to 130,000 FCFA of unexplained gaps. By scanning items in and out she cut shrinkage below 1 %, roughly 100,000 FCFA recovered per month. Reorder alerts spared her six stockouts on best-sellers in one quarter. Cost: 6,000 FCFA/month. Estimated net gain in year one: over 1,500,000 FCFA.
FAQ
Do I need an expensive barcode scanner? No. An entry-level Android phone camera scans EAN barcodes. A Bluetooth scanner at 15,000-30,000 FCFA speeds up checkout in store but stays optional at the start.
What about products with no barcode, like crafts? The app generates and prints internal labels. Each unique piece gets a code, so you can track even handmade items one by one.
Does it work without internet? Yes, a good app runs offline and syncs the moment the network returns. Essential in a market where 3G is intermittent.
How long to enter everything at first? Budget 1 to 2 days for 300-500 SKUs, often spread over a week. Scanning supplier deliveries then feeds the database as you go.
Can I see my best sellers? Yes. Analytics rank SKUs by rotation and margin, telling you what to reorder and what to drop. That is often what pays back the subscription fastest.
