The verdict in three sentences
A small shop bleeds margin on three fronts: stockouts (lost sales), shrinkage (1-5% of sales gone) and dead stock (cash trapped on shelves). An inventory app with reorder points, barcodes and a fast/slow-mover report makes those losses visible and pays for itself. In Dar es Salaam, expect 500,000 to 1,800,000 FCFA, with an essential low-data offline mode.
Barcode or manual entry: the real trade-off
Manual entry is free but slow and error-prone. Barcodes speed checkout, keep stock accurate and make the evening Z-report reliable. For a high-volume shop it quickly pays off; for a tiny store, quick-add without scanning can be enough to start.
| Criterion | Manual entry | Barcode |
|---|---|---|
| Checkout speed | Slow | Fast |
| Stock accuracy | Medium | High |
| Price errors | Frequent | Rare |
| Shrinkage detection | Hard | Clear |
| Hardware cost | 0 | Scanner ~30,000-60,000 FCFA |
| Best for | Tiny volume | Medium to high volume |
What the app makes visible and recoverable
| Leak | Without app | With app | Estimated 2026 gain |
|---|---|---|---|
| Shrinkage | 1-5% of sales | Inventory + alerts | -1 to -3 points |
| Stockouts | Lost sales | Auto reorder points | -30 to -50% stockouts |
| Dead stock | Cash trapped | Mover report | Cash freed |
| Supplier price | From memory | Price history | Better negotiation |
| Customer credit (tab) | Notebook | Credit ledger | Traced receivables |
| Cash close | Approximate | Daily Z-report | Variances caught |

Neema runs a multi-product shop in Dar es Salaam: 6,000,000 FCFA revenue/month. A 3% shrinkage means 180,000 FCFA/month lost; stockouts cost her another dozen missed sales. With the app (barcode, reorder points, Z-report), she brings shrinkage to 1.5% and halves stockouts: about 150,000 FCFA/month recovered. On a 1,000,000 FCFA build, payback lands near 7 months.
FAQ
How much is an inventory app in 2026? From 500,000 FCFA for the essentials (products, alerts, Z-report) to 1,800,000 FCFA with multi-branch, barcodes, customer credit and supplier history.
Do I need a barcode scanner? No, quick-add without scanning is enough to start; a scanner (30,000-60,000 FCFA) makes sense as volume grows and clearly speeds checkout.
Does the app work offline? Yes, low-data offline mode stores sales and stock movements locally then syncs, suited to frequent network outages.
Can it handle credit customers (tabs)? Yes, a customer-credit ledger tracks each tab and its repayment, cutting forgotten receivables.
Is mobile money integrated at checkout? Yes, mobile-money collection at checkout is supported, with a daily Z-report to reconcile cash and electronic payments.
