The verdict in three sentences
A multi-tenant SaaS platform — many clients served by one application, with strict data isolation — is built for FCFA 12 to 35 million (about USD 20,000 to 58,000) in 2026, over 5 to 9 months. Operations require FCFA 200,000 to 700,000/month of hosting and FCFA 500,000 to 1.5 million/month of maintenance. The economic key: bill by subscription with local payments (mobile money) to turn this fixed cost into recurring revenue.
What development costs
Multi-tenant is not a classic website: you must handle data isolation, subscription billing, roles and an architecture that scales without a rebuild.
| Item | 2026 estimate (FCFA) |
|---|---|
| Scoping + architecture | 1,500,000 - 4,000,000 |
| Multi-tenant core + isolation | 4,000,000 - 10,000,000 |
| Subscription billing + payments | 2,500,000 - 7,000,000 |
| Back-office + roles + analytics | 3,000,000 - 9,000,000 |
| Testing + go-live | 1,000,000 - 5,000,000 |
| Total development | 12,000,000 - 35,000,000 |
The 5 to 9 month timeline depends mainly on module count and required isolation level (shared database with logical partitioning vs a dedicated database per client).
Operations and revenue model
Once live, the platform generates recurring costs that client subscriptions must cover.
| Recurring item | 2026 estimate (FCFA/month) |
|---|---|
| Cloud hosting | 200,000 - 700,000 |
| Maintenance (fixes + evolutions) | 500,000 - 1,500,000 |
| Payments (mobile money fees) | 1 - 2% of volume |
| Support + monitoring | 300,000 - 800,000 |
Typical model: 40 clients at FCFA 30,000/month = FCFA 1,200,000 MRR, i.e. FCFA 14.4M/year. With FCFA 900,000/month of costs (hosting + maintenance + support), monthly margin is FCFA 300,000 and rises with each new client, since the marginal cost of an extra tenant is low.
Mini case study
Sarah, founder of a management platform for pharmacies in Nairobi, has a multi-tenant SaaS built for FCFA 22,000,000 with mobile-money billing. She targets 60 pharmacies at FCFA 35,000/month, i.e. MRR of FCFA 2,100,000 and ARR of FCFA 25.2M. Her operating costs (hosting 400,000 + maintenance 900,000 + support 400,000) reach FCFA 1,700,000/month, leaving FCFA 400,000 monthly margin at 60 clients. She amortises the initial build in about 14 months of net MRR, then each new pharmacy adds nearly FCFA 30,000 of margin.

FAQ
Why does multi-tenant cost more than a classic website?
Because you must guarantee data isolation between clients, robust subscription billing and a scalable architecture. This core often represents 30 to 40% of the development budget.
Which data-isolation level to choose?
Two options: shared database with logical partitioning (cheaper, simpler) or a dedicated database per client (costlier, required in health or finance). The choice affects 15 to 25% of cost.
Can we integrate mobile money for subscriptions?
Yes, and it is recommended in the region. Budget 1 to 2% commission on volume and a recurring-billing module.
What monthly budget to run the platform?
Between FCFA 1,000,000 and 3,000,000/month all-in (hosting, maintenance, support), depending on client count and service level.
How long to launch?
Budget 5 to 9 months to MVP production. A first release with billing and 2-3 key modules can ship in 4 months.
