The verdict in three sentences
The unanticipated stockout costs more than overstock: a missing SKU is a lost sale and a customer who walks to the competitor. An inventory app with automatic alert thresholds drops stockouts by 35 % and adds about 5 margin points by cutting emergency purchases. In Lagos in 2026, budget around 1,800,000 FCFA for a multi-store app handling 3,000 SKUs, delivered in 7 weeks.
Why stockouts cost more than overstock
Overstock ties up cash, but a stockout destroys revenue and trust. Without a tool, an owner learns of a stockout when a customer points it out: too late. The app flips the logic with a per-SKU alert threshold that fires a notification before zero, plus mobile barcode scanning that replaces error-prone paper counts.
| Item | Without app | With app (2026) |
|---|---|---|
| Stockout rate | 18 % of SKUs | 12 % (-35 %) |
| Count time (3,000 SKUs) | 2 days on paper | 4 hours by scan |
| Counting errors | 6 to 9 % | under 1 % |
| Stock valuation | monthly, estimated | real time |
| Emergency buys (extra cost) | frequent | rare |
| Net margin | baseline | +5 points |
What the app covers and what it costs
Budget depends on SKU count, multi-store scope and scanning hardware. Here is a 2026 order of magnitude for the market.
| Tier | Scope | Indicative cost |
|---|---|---|
| Essential | 1 store, 800 SKUs, alerts | 900,000 FCFA |
| Standard | 3,000 SKUs, barcode scan, valuation | 1,800,000 FCFA |
| Multi-store | 3 outlets, transfers, reporting | 2,600,000 FCFA |
| Scanner hardware (per station) | Bluetooth scanner | 120,000 FCFA |
| Monthly maintenance | hosting + support | 70,000 FCFA/mo |
| Team training | 2 on-site sessions | included |
Mini case study
Fatoumata runs a hardware store in Lagos with 3,000 SKUs and 2 outlets. Before the app, stockouts hit 18 % of SKUs; on monthly revenue of 40,000,000 FCFA she estimated losing 6 % of sales, about 2,400,000 FCFA/month. With alert thresholds, stockouts fall to 12 % and recover about 800,000 FCFA of sales per month. The app cost 1,800,000 FCFA: it is paid back in a little over two months, not counting the 5 margin points saved on avoided emergency buys.
