The verdict in three sentences
A decentralised financial system (SFD) with 10,000 to 60,000 members in Bamako can no longer run its portfolio on ageing software and Excel rework for BCEAO returns. A custom core system costs 20,000,000 to 60,000,000 FCFA (30,500 to 91,500 EUR) in 2026, with a 4 to 8 month rollout, covering loans, savings, BCEAO reporting, mobile money and a full audit trail. The gain shows mainly in portfolio at risk and in regulatory reporting time, which drops from several days to a few hours.
2026 budget by institution size
Cost depends on membership, branch count and channels (counter, field agents, mobile money).
| Institution profile | Scope | Indicative budget | Timeline |
|---|---|---|---|
| 10,000 to 20,000 members, 3 to 5 branches | Members, savings, loans, accounting | 20,000,000 to 30,000,000 FCFA | 4 to 5 months |
| 20,000 to 40,000 members, 5 to 10 branches | + automated BCEAO reporting, mobile money | 30,000,000 to 45,000,000 FCFA | 5 to 6 months |
| 40,000 to 60,000 members, 10+ branches | + offline field agent app, CEO dashboard | 45,000,000 to 60,000,000 FCFA | 6 to 8 months |
| Data migration from legacy software | Members, outstanding loans, 5-year history | 2,500,000 to 6,000,000 FCFA | 4 to 8 weeks |
| Annual maintenance and hosting | Regulatory updates, backups, support | 3,000,000 to 9,000,000 FCFA per year | Ongoing |
Regulatory updates (new returns, prudential ratios) are included in maintenance: check this point in any contract.
Custom build, international package or regional solution
Institutions in the WAEMU zone often hesitate between an international package, a regional solution and a dedicated build.
| Criterion | International package | Regional solution | Custom build |
|---|---|---|---|
| Entry cost | 40,000,000 to 120,000,000 FCFA | 15,000,000 to 35,000,000 FCFA | 20,000,000 to 60,000,000 FCFA |
| Annual licence | 8,000,000 to 25,000,000 FCFA | 3,000,000 to 8,000,000 FCFA | None, 15% maintenance |
| BCEAO returns and prudential ratios | Costly configuration | Usually included | Native, mapped to your chart of accounts |
| Orange Money and Moov Money integration | Specific development | Variable | Planned from the specification |
| Specific products (group lending, tontines, warehouse receipts) | Often rigid | Partial | Designed to fit |
| Support in Bamako | Remote, in English | Regional | Local, in French |
Security and control: what the banking commission expects
An SFD's software is a control tool as much as a management tool. These requirements must be written explicitly into the specification.
| Requirement | What to plan for | Indicative share of budget |
|---|---|---|
| Audit trail | Tamper-proof log of every operation, user and timestamp | 5 to 8% |
| Segregation of duties | Entry, approval and disbursement by separate profiles | 3 to 5% |
| Daily closing | Cash count per branch, flagged discrepancies | 4 to 6% |
| Backups | Encrypted daily copy, separate recovery site | 3 to 5% |
| BCEAO reporting | Periodic returns, ratios, credit registry | 10 to 15% |
| Anti-money laundering | Alert thresholds, member identification, reports | 4 to 7% |

He commissions a custom system for 38,000,000 FCFA (about 58,000 EUR), plus 5,700,000 FCFA of annual maintenance. Thanks to due-date alerts, SMS reminders and mobile money repayments, portfolio at risk falls to 4.5% within 12 months: 135,000,000 FCFA of outstanding loans cleaned up. Assuming a final loss of 30% on at-risk loans, the provision avoided is around 40,000,000 FCFA, more than the investment in the first year. Reporting drops to 1 day a month.

Between 20,000,000 and 60,000,000 FCFA (30,500 to 91,500 EUR) in 2026 depending on institution size and modules. Plan 15% of that amount per year for maintenance and regulatory updates.
