The verdict in three sentences
A retail shop bleeds money on two invisible fronts: stockouts that send customers to competitors, and overstock that sleeps on the shelf and freezes cash. A POS + inventory app with threshold alerts and real-time stock movements removes these blind spots for 1,000,000 to 3,000,000 FCFA. The payback shows within the first quarter: stockouts down 30 %, overstock down 20 %, and physical counts 3x faster.
What each module costs and returns
A useful MVP does not try to cover everything. It first fixes visibility: knowing what is left, what sells fast, what sleeps. Here are the modules ranked by priority with 2026 orders of magnitude.
| Module | Priority | Cost (FCFA) | Main gain |
|---|---|---|---|
| Product catalog + variants | Core | 300,000 - 500,000 | Foundation, no more duplicates |
| Stock in / out + history | Core | 250,000 - 450,000 | Accurate real-time stock |
| Low-threshold alerts | Core | 150,000 - 300,000 | Stockouts -30 % |
| POS + sales receipt | Core | 300,000 - 600,000 | Fast checkout |
| Mobile money (Wave/OM) | High | 250,000 - 500,000 | +15-25 % checkout conversion |
| Sales reports + top products | High | 200,000 - 400,000 | Overstock -20 % |
| Multi-store | Option | 400,000 - 900,000 | Per-outlet consolidation |
| E-commerce connection | Option | 500,000 - 1,200,000 | Single stock shop + web |
The right scope for your size
A single shop with fewer than 500 SKUs does not need multi-store or e-commerce from day one. The classic trap is paying for modules never used. The rule: connect e-commerce only once physical stock is already 95 %+ reliable, otherwise you sell online products no longer on the shelf.
| Shop profile | Recommended scope | Budget (FCFA) | Timeline |
|---|---|---|---|
| Single shop < 500 SKUs | Core + mobile money | 1,000,000 - 1,500,000 | 5-6 weeks |
| Shop + advanced reports | Core + reports | 1,500,000 - 2,200,000 | 6-7 weeks |
| 2-3 outlets | + multi-store | 2,200,000 - 3,000,000 | 7-9 weeks |
| Shop + online sales | + e-commerce connection | 2,500,000 - 3,000,000+ | 8-9 weeks |
Mini case study
Fatou runs a cosmetics shop in Thies with monthly revenue of 3,500,000 FCFA and 600 SKUs. She estimates losing 12 % of sales to stockouts, or 420,000 FCFA/month, and freezing 1,800,000 FCFA in slow-moving products. She invests 1,400,000 FCFA in a POS + inventory + alerts + Wave MVP.
With stockouts cut by 30 %, she recovers about 126,000 FCFA of sales per month (30 % of 420,000). By freeing 20 % of overstock, she recovers 360,000 FCFA of cash immediately. On recovered sales alone, the app pays for itself in a little over 11 months — not counting the counting time saved, down from 2 days to half a day each month.

What does a POS + inventory MVP really cost in 2026?
For a single shop, budget 1,000,000 to 1,500,000 FCFA for core modules plus mobile money. Advanced features (multi-store, e-commerce) push the budget toward 2,000,000 - 3,000,000 FCFA.
How long until delivery?
A working MVP ships in 5 to 9 weeks depending on scope. A single shop without e-commerce is usually operational in 5 to 6 weeks, training included.
Does the app work offline?
Yes, essential in Senegal. The POS records sales locally and syncs as soon as the connection returns, avoiding any interruption during a network outage.
Can Wave and Orange Money connect to the POS?
Yes. Mobile money collection is built into the sales receipt and raises checkout conversion by 15 to 25 %, because the customer does not need exact cash.
When should you move to multi-store?
As soon as you have a second outlet with stock transfers between shops. Below that, the module adds complexity without real gain.
