The verdict in three sentences
Custom internal business software for an emerging-markets operation, scoped from a London HQ, costs 9 500 to 28 000 GBP (roughly 6 000 000 to 18 000 000 FCFA) in 2026 depending on modules (stock, sales, clients, reporting). A one- or two-module MVP starts at 9 500 - 14 000 GBP (6 000 000 - 9 000 000 FCFA) and ships in 8 to 12 weeks before being extended. Expect a 20 to 35 % productivity gain, a training budget and annual maintenance around 15 % of build.
From spreadsheets to software: what changes
Shared spreadsheets hit their limits fast: duplicates, entry errors, no access rights, no reliable history. Business software structures these flows. Here is the cost per module.
| Module | What it delivers | 2026 range (GBP) |
|---|---|---|
| Stock management | In/out, threshold alerts | 3 200 - 7 000 |
| Sales & invoicing | Quotes, invoices, tax | 4 000 - 8 000 |
| Clients (light CRM) | Records, history, follow-ups | 2 800 - 6 300 |
| Reporting & dashboards | Real-time KPIs, exports | 2 400 - 5 500 |
| Rights & multi-user | Roles, traceability | 1 600 - 4 000 |
A full four-module system therefore lands around 19 000 - 28 000 GBP (12 000 000 - 18 000 000 FCFA). Starting with a two-module MVP limits risk and spreads the investment.
MVP, rollout and total cost
The right approach is to ship a useful MVP into production, then extend. Here are the tiers and their recurring costs.
| Tier | Scope | Timeline | 2026 cost (GBP) |
|---|---|---|---|
| MVP 1-2 modules | Stock + sales | 8 - 12 weeks | 9 500 - 14 000 |
| Extended software | 3-4 modules + rights | 14 - 20 weeks | 16 000 - 24 000 |
| Full software | 4 modules + advanced reporting | 20 - 26 weeks | 24 000 - 28 000 |
| Team training | Sessions + support | included/option | 800 - 2 400 |
| Annual maintenance | Fixes + evolutions | recurring | ~15 % of build/yr |
Maintenance at 15 % of build (1 400 to 4 200 GBP/yr) covers fixes, security and small evolutions. It is a cost to plan from day one and often underestimated.

Mini case study
Mr. Kouassi, manager of a building-materials distributor (28 staff) overseen from a London parent company, runs his stock on three manually synced spreadsheets. He orders a stock + sales MVP at 12 000 GBP delivered in 10 weeks, plus 1 400 GBP training. His teams spent about 6 hours/week reconciling files and regularly corrected stock errors. With an estimated 25 % productivity gain on those tasks and the end of unplanned stockouts, he saves the equivalent of ~1.3 monthly salaries each month. The software pays for itself in under 10 months, including 1 800 GBP annual maintenance.
FAQ
How much is internal business software for this market? Between 9 500 and 28 000 GBP (6 000 000-18 000 000 FCFA) in 2026 by modules. A one- or two-module MVP starts at 9 500-14 000 GBP; a full four-module system reaches 28 000 GBP.
Why not stay on spreadsheets? Spreadsheets handle neither access rights, nor reliable history, nor simultaneous multi-user work. The productivity gain of real software is estimated at 20-35 % on entry and reconciliation tasks.
Should we build everything at once? No. A two-module MVP (9 500-14 000 GBP) delivered in 8-12 weeks validates usage before extending. This spreads the investment and lowers risk.
How much is maintenance? About 15 % of build per year, i.e. 1 400 to 4 200 GBP. It covers fixes, security updates and small functional evolutions.
Is training essential? Yes, for adoption. Budget 800 to 2 400 GBP of sessions and support. Software the teams do not adopt generates no productivity gain.
