The verdict in three sentences
A building materials merchant with 4 depots losing 6% of its stock a year to inventory shrinkage is already paying for custom software without knowing it. A well-built merchant software in Yaoundé costs between 12 and 28 million FCFA (about 18,300 to 42,700 EUR), goes live in 3 months and pays back in 12 to 20 months through recovered stock and controlled receivables. The module that earns the most is the per-customer credit limit, followed by traceable inter-depot transfers.
What building materials merchant software must do in 2026
Cement, rebar and tiles share three traits: heavy volumes, thin margins (8 to 15% on cement, 18 to 30% on tiles) and a high share of credit sales to construction contractors. A spreadsheet or generic POS tracks neither depot transfers, nor customer balances, nor partial deliveries on a 400-bag order.
| Module | Key function | Share of budget | 2026 range (FCFA) |
|---|---|---|---|
| Multi-depot stock | Receipts, issues, traced transfers, cycle counts | 25% | 3,000,000 to 7,000,000 |
| Customer credit | Balances, per-customer limit, automatic block, reminders | 20% | 2,400,000 to 5,600,000 |
| Connected tills | Counter sales, receipts, till closing per depot | 15% | 1,800,000 to 4,200,000 |
| Mobile payment | Orange Money and MTN MoMo, automatic reconciliation | 10% | 1,200,000 to 2,800,000 |
| Delivery notes | Partial deliveries, trucks, drivers, proof of receipt | 12% | 1,450,000 to 3,350,000 |
| Dashboards | Margin by family, turnover, stock-out alerts | 10% | 1,200,000 to 2,800,000 |
| Training and data migration | Items, customers, opening balances | 8% | 950,000 to 2,250,000 |
These amounts are a 2026 order of magnitude for a Cameroonian SME with 4 to 6 outlets. The low end covers a standard scope, the high end covers complex pricing rules (site price, reseller price, volume discounts) and a mobile app for field sales reps.
Before and after: where the money goes
The first gain is inventory shrinkage. On an average stock of 180 million FCFA, a 6% gap means 10.8 million FCFA lost each year: unreported breakage, bags leaving without a slip, transfer errors. The second is customer credit: without a blocking limit, bad debts drift quickly.
| Indicator | Before (spreadsheet + notebooks) | After software (12 months) |
|---|---|---|
| Annual inventory shrinkage | 6% | 1.5% to 2% |
| Value lost on 180M FCFA of stock | 10,800,000 FCFA | 2,700,000 to 3,600,000 FCFA |
| Bad debts / credit sales | 7% | 2.5% to 3% |
| Average collection period | 68 days | 40 to 45 days |
| Till closing time per depot | 1 h 30 | 20 min |
| Stock-outs on key items (cement, 10 mm rebar) | 9 per month | 2 to 3 per month |
| Orange Money and MoMo reconciliation | Manual, 2 days a month | Automatic |
Mobile payment also improves security: less cash in the till, fewer trips to the bank, and every Orange Money or MTN MoMo transaction is tied to its sales slip. Merchant fees run around 1 to 2% depending on the contract negotiated with the operator.
Typical 3-month plan
Month one is scoping: item catalogue (one tile in 4 sizes and 3 grades), pricing rules and the credit approval flow. Month two delivers stock, tills and credit on a pilot depot. Month three rolls out the other three depots, connects mobile payment and trains cashiers. Plan an offline mode: a network outage in Mvan or Nkolbisson must never block a sale, data syncs when the connection returns.
Mini case study
Paul, manager of a 4-depot merchant in Yaoundé (cement, rebar, tiles), turns over 1.2 billion FCFA, 40% of it on credit. He picks software at 19 million FCFA plus 2.4 million FCFA a year for maintenance and hosting.

- Shrinkage cut from 6% to 2% on 180M FCFA: 7.2M FCFA saved per year.
- Bad debts cut from 7% to 3% on 480M FCFA of credit sales: 19.2M FCFA of losses avoided.
- Total first-year gain: 26.4M FCFA, minus 2.4M FCFA maintenance, so 24M FCFA net.
The project pays back in just under 10 months, on a conservative estimate.
FAQ
How much does building materials merchant software cost in Yaoundé in 2026?
Budget 12 to 28 million FCFA for custom development covering multi-depot stock, customer credit and tills. Maintenance and hosting add 150,000 to 300,000 FCFA per month.
Does the software work without internet?
Yes, if offline mode is planned from scoping. Tills keep selling and sync sales within 2 minutes once the network is back.
How is the credit limit enforced?
Each customer has a maximum balance, for example 5 million FCFA for a regular contractor. Beyond it, the sale is blocked and only the manager's approval on his phone unlocks it.
Can we accept Orange Money and MTN MoMo?
Yes, both operators are integrated with automatic payment reconciliation. Merchant fees usually sit between 1 and 2% depending on volume.
How long to go live across 4 depots?
About 3 months: 1 month scoping, 1 month pilot on one depot, 1 month rollout and training. A full opening stock count is essential.
