The verdict in three sentences
A precise requirements brief turns a fuzzy project into a controlled fixed price and cuts the change requests that blow up budgets. First frame the roles, workflows, payment integrations and offline mode that unstable West African networks make essential. Budget 2026: 3,000,000 to 8,000,000 FCFA for an MVP, 10,000,000 to 30,000,000 FCFA for a full platform, with maintenance at 15 to 20%/year.
The essential sections of the requirements brief
A business app brief covers far more than screens. Here is the minimum structure to provide before consultation.
| Section | To specify | Impact if omitted |
|---|---|---|
| Modules | Core vs optional functions | Fuzzy scope, change requests |
| Users & roles | Profiles, rights, hierarchy | Access rework mid-project |
| Workflows | Steps, approvals, notifications | Business logic redone |
| Payment API | Wave, Orange Money, split | Integration delay |
| Offline mode | Sync, local cache | Unusable in weak-network zones |
| Hosting | Location, backup | Compliance risk |
A brief covering these six sections lets the agency commit to a firm fixed price rather than open time-and-materials.
FCFA budget benchmarks 2026 by ambition
Cost depends on functional scope and number of integrations. 2026 orders of magnitude in Abidjan and Douala.
| Level | FCFA budget 2026 | Timeline | Typical content |
|---|---|---|---|
| MVP (1 core module) | 3,000,000 - 8,000,000 | 4-6 months | 1 workflow, payment, mobile |
| Standard app | 8,000,000 - 15,000,000 | 6-9 months | 3-4 modules, roles, dashboard |
| Full platform | 10,000,000 - 30,000,000 | 9-14 months | Multi-module, API, offline |
| Annual maintenance | 15-20% of project cost | Per year | Fixes, enhancements, support |
The single-core-module MVP is the recommended path: it validates real usage before investing in the full platform.

Mini case study
Mr. Kouassi, director of a distribution firm in Abidjan, wants a route-management app with Wave payments for his 25 delivery riders. Without a brief, a first vendor quoted "around 5,000,000 FCFA" then piled on change requests up to 11,000,000 FCFA. Kouassi restarts scoping: he writes a brief covering 1 core module (routes), roles (rider, supervisor), Wave API and offline mode. Result: a firm MVP fixed price at 6,500,000 FCFA, 5-month timeline, maintenance at 18%/year, i.e. 1,170,000 FCFA/year. The precise brief spares him the 6,000,000 FCFA of change requests from the first scenario and secures code ownership through a reversibility clause, crucial given local vendor turnover.
FAQ
Why does a brief enable a fixed price rather than time-and-materials? Because a written, approved scope gives the agency the visibility to commit to a firm price. Without a brief, it bills by the hour and the budget drifts with each new request.
Is offline mode really necessary? In West Africa, yes, as soon as users work in the field or in unstable-network zones. The app must run locally then sync. Omitting it makes the tool unusable on the ground.
How do you integrate Wave and Orange Money into a business app? Via their APIs and confirmation webhooks. The brief must specify use cases (collection, merchant split) and failure scenarios. It is a line item to price explicitly, not a free option.
What is a reversibility clause? The vendor's commitment to deliver source code, documentation and access at contract end, so you can switch agencies without starting over. It is critical given the high turnover of local vendors.
What maintenance budget should you plan? 2026 order of magnitude: 15 to 20% of project cost per year, i.e. 1,500,000 to 3,000,000 FCFA for a 10,000,000 FCFA app. It covers fixes, minor enhancements and support.
