The verdict in three sentences
A building-supplies store quoting by hand in a notebook loses margin on every cement or steel price rise and lets untracked customer credit slip away. A vertical app (multi-unit stock bag/ton/piece, quotes in minutes, credit-customer ledgers, MoMo/bank settlement) turns a quote from hours into minutes and protects margin on volatile prices. In Lagos as in Cotonou, it's the tool that turns quote-and-stock chaos into controlled cash flow.
The real problem: volatile prices and multiple units
A building-materials dealer's headache is selling in several units (bag, ton, piece, metre) at prices that move weekly, while extending credit. Impact of an app (2026 order of magnitude, store with FCFA 80,000,000 annual revenue).
| Indicator | Without app | With app |
|---|---|---|
| Time for one quote | 2 – 4 hours | 5 – 10 minutes |
| Stocktake accuracy | 70% | 97% |
| Margin lost (mispriced quotes) | ~2,400,000 FCFA/yr | ~400,000 FCFA/yr |
| Customer credit tracked | approximate | 100% traced |
| Bad debt / forgotten tabs | ~1,500,000 FCFA/yr | ~300,000 FCFA/yr |
Between protected margin and recovered debt, the app can secure ~FCFA 3,200,000/year — several times its cost.
Key features and costs
The app must handle multiple units and credit without needless jargon. Scope and 2026 indicative costs:
| Module | Benefit | Indicative cost |
|---|---|---|
| Multi-unit stock (bag/ton/piece) | Zero conversion errors | Included in base |
| Fast quote + convert to invoice | Quotes in minutes | Included in base |
| Cement/steel price updates | Margin protected | Included in base |
| Credit-customer ledger | Tabs traced, reminders | +250,000 FCFA |
| MoMo / bank settlement | Secured collection | +200,000 FCFA |
| Multi-warehouse | Consolidated stock | +400,000 FCFA |
The base (multi-unit stock + quotes + prices) starts at FCFA 900,000; a full solution with credit ledger and MoMo settlement reaches FCFA 1,400,000 to 1,600,000.
Mini case study
Ibrahim, who runs a hardware/BTP store in Lagos (Ojota), does FCFA 80,000,000 in revenue. His manual quotes took 3 hours and he lost ~FCFA 2,400,000/year in margin on mis-entered prices, plus ~FCFA 1,500,000 in forgotten tabs. He invests FCFA 1,500,000 in an app with multi-unit stock, fast quotes and a credit ledger. Quotes in 8 minutes, margin loss down to ~400,000 FCFA and bad debt to ~300,000 FCFA: he secures ~FCFA 3,200,000 in the first year. The tool is paid off in under six months.

FAQ
How does the app handle prices that change every week?
You update the buy and sell price of cement, steel and other materials in a single place; all future quotes use the current price, protecting margin on volatile products.
Can it sell in bags, tons and pieces at the same time?
Yes. Each SKU has its units and conversions; the quote automatically computes the right price whatever unit is chosen, with no conversion errors.
How do I track credit customers?
The per-customer ledger traces every tab, every payment and the remaining balance, with automatic reminders. Forgotten bad debt typically drops from ~1,500,000 to ~300,000 FCFA a year.
Does it accept Mobile Money?
Yes — MoMo, Wave and bank transfer. Collection is linked to the invoice and the customer ledger, making reconciliation reliable.
How much does the hardware app cost in 2026?
From FCFA 900,000 for the base (multi-unit stock, quotes, prices) to FCFA 1,600,000 with credit ledger, MoMo settlement and multi-warehouse.
