The verdict in three sentences
With 25,000 daily savers and 80 collectors, a microfinance institution (MFI) running on paper booklets carries permanent cash risk and a 24 to 72-hour posting delay. A mobile collection app with instant SMS receipts, synced to the core banking system, costs EUR 40,000 to 70,000 in 2026 when funded and overseen from Amsterdam, with a 4-month timeline. The fastest gain comes from lower cash discrepancies and saver trust, since every deposit gets a proof.
The hidden cost of paper booklets
Daily doorstep savings is a flagship product for West African MFIs, which many Dutch impact funds and NGOs finance: the collector visits markets and neighbourhoods every day, takes in the equivalent of EUR 0.75 to 7.50 per client and writes the deposit in two booklets. In the evening the cash goes to the branch teller and manual entry follows, sometimes the next day.
| Indicator | Paper booklets | Collection app | Change |
|---|---|---|---|
| Posting delay into the core system | 24 to 72 h | Real time or end of round | -95 % |
| Monthly cash discrepancies | 1.2 to 2 % of collections | 0.1 to 0.3 % | about -85 % |
| Teller data entry time | 3 full-time staff | 0.5 staff | 2.5 roles freed |
| Saver complaints per month | 150 to 250 | 20 to 40 | -80 % |
| Proof of deposit for the client | Handwritten booklet | Time-stamped SMS receipt | Full traceability |
| Consumables (booklets, receipts) per year | EUR 4,500 to 6,900 | EUR 900 of SMS above bundle | -EUR 3,800 |
With an average daily deposit of about EUR 2.30 per saver, 25,000 active savers represent roughly EUR 57,000 a day, close to EUR 1.37M a month over 24 working days. A 1.5 % discrepancy means about EUR 20,500 of flows to explain every month, a figure that investors and auditors notice.
Features and 2026 budget
The app must work in low-coverage areas, on entry-level Android phones, and stay simple for collectors who are not used to digital tools. Development by a team with West African field experience keeps costs below a Dutch agency rate.
| Module | Features | Indicative budget |
|---|---|---|
| Collector Android app (offline) | Round client list, amount entry, deferred sync | EUR 11,000 to 17,000 |
| SMS receipt and notifications | Instant SMS with balance, local aggregator integration | EUR 3,000 to 5,000 |
| Branch back office | Till opening, cash handover, automatic reconciliation, discrepancy control | EUR 9,000 to 15,000 |
| Core banking synchronisation | Connector to the MFI's management system (API or files) | EUR 8,000 to 15,000 |
| Management and investor dashboard | Collections per agent and area, delays, alerts, impact KPIs | EUR 4,000 to 8,000 |
| Mobile money option | Deposits by Orange Money or Moov Money straight to the account | EUR 3,000 to 5,000 |
| Total | Core to full version | EUR 40,000 to 70,000 |
On compliance, the app must meet BCEAO rules for decentralised financial systems: traceability of every operation, separation of collector, teller and controller roles, archiving, plus local data protection law and, when European funders receive saver data, GDPR principles. Also budget for devices (80 smartphones at about EUR 140, i.e. EUR 11,000) if collectors are not equipped, and SMS at roughly EUR 0.02 per message.
Mini case study
Sanne, investment manager at an Amsterdam impact fund financing an MFI in Burkina Faso (80 collectors, 25,000 daily savers), sees an average 1.4 % discrepancy on monthly collections and 3 tellers dedicated to data entry. She co-funds a version at EUR 58,000, plus EUR 11,000 of smartphones.
Calculation: the discrepancy drops to 0.25 %, a 1.15-point reduction on EUR 1.37M a month. If only a third of those discrepancies were real losses, the saving reaches about EUR 5,200 a month. Add 2.5 data-entry roles redeployed to loan recovery (about EUR 760 a month fully loaded) and EUR 3,800 of consumables a year. Total monthly gain: about EUR 6,300. The EUR 69,000 investment pays back in about 11 months, and the fund gets reliable real-time portfolio data.
