The verdict in three sentences
For a microfinance institution in Nairobi with 28,000 members and 9 branches, a PAR30 above 5% and regulatory returns prepared by hand cost far more than the software that would fix them. A vendor core banking system costs USD 70,000 to 160,000 (40,000,000 to 90,000,000 FCFA), a custom lending and collections module plugged into the existing system USD 27,000 to 53,000 (15,000,000 to 30,000,000 FCFA), delivered in 6 months. The priority is rarely to replace the accounting core: first equip loan origination, repayment tracking and mobile money repayments (M-Pesa in Kenya, Orange Money or Wave in West Africa).
The cost of a high PAR30
Take a loan book of USD 10.7 million (6,000,000,000 FCFA) across 9,000 active loans, with a current PAR30 of 9%.
| Indicator (2026 ballpark) | Current situation | Target |
|---|---|---|
| Loan book | USD 10.7 million | USD 10.7 million |
| PAR30 | 9%, or USD 963,000 | 5%, or USD 535,000 |
| Annual loss rate on the book | 2.5%, or USD 268,000 | 1.2%, or USD 128,000 |
| Repayments collected at branches | 85% | 45% (rest via mobile money) |
| Time to produce regulatory returns | 6 days a month | 1 day |
| Average loan processing time | 10 days | 3 days |
| Loan officers per 1,000 loans | 4.5 | 3 |
Lower losses alone, about USD 140,000 a year, pay for the custom module in under 5 months.

Mini case study
Mr Otieno, CEO of a 28,000-member microfinance institution in Nairobi, runs a USD 10.7 million loan book with a PAR30 of 9%. He invests USD 43,000 in a custom module, plus USD 6,200 a year of maintenance. SMS reminders before due dates and M-Pesa repayments bring PAR30 down to 6% in year one, and the loss rate from 2.5% to 1.6%, saving USD 96,000. Add 5 days of reporting freed each month, and the module pays back in about 6 months.

FAQ
How much does microfinance software cost in 2026?
A vendor core banking system costs USD 70,000 to 160,000 for a mid-sized institution. A custom lending and collections module costs USD 27,000 to 53,000 (15,000,000 to 30,000,000 FCFA).
Does the software produce regulatory returns?
Yes, periodic returns and prudential ratios are generated from lending and savings data. Production drops from about 6 days to 1 day a month.
Can members repay by mobile money?
Yes, each instalment can be paid by M-Pesa, Orange Money or Wave, and the payment is automatically allocated to the right loan. Merchant fees sit around 1% depending on the contract.
What PAR30 should a microfinance institution target?
Regulators and investors treat a PAR30 above 3 to 5% as a warning sign. A 5% target in year one, then 3%, is realistic with daily arrears monitoring.
Why a 6-month timeline?
The module touches members' financial data: thorough testing, a pilot branch and training across 9 branches take 6 to 8 weeks on their own.
