The verdict in three sentences
An Amsterdam microfinance lender serving 12,000 small business clients with a 30-day portfolio at risk between 6 and 9 % is losing money, and an ageing core lending system is often part of the cause: rigid schedules, manual collections and monthly regulatory and investor reports assembled by hand. Replacing the whole system is expensive and takes 12 to 18 months, while a custom loan module connected to the existing core can tackle the problem in 4 months. Dutch agencies quote 100,000 to 300,000 EUR for such a build; Kolonell prices it at 7,000,000 to 15,000,000 FCFA (10,670 to 22,870 EUR), depending on loan products and integrations.
The real cost of an 8 % PAR30 for a microlender
With an average outstanding loan of 15,000 EUR, 12,000 borrowers represent about 180 million EUR of portfolio. At 8 % PAR30, that is 14.4 million EUR overdue, weighing on provisions, funding covenants and relations with guarantors such as the EIF.
| Indicator | Common situation in 2026 | Target with loan module | Impact |
|---|---|---|---|
| PAR30 | 6 to 9 % | 3 to 5 % | covenant headroom |
| Time to detect a late payment | 7 to 15 days | D+1 | immediate follow-up |
| Collections contacts per officer per day | 10 to 15 calls | 30 automated messages + 15 targeted calls | 3x coverage |
| Share of repayments by direct debit or iDEAL | 50 to 70 % | 85 to 95 % | fewer missed payments |
| Monthly regulatory and investor reporting time | 4 to 6 days | under 1 day | higher reliability |
| Loan files processed per officer per week | 8 to 12 | 15 to 20 | portfolio growth |
These figures are 2026 estimates for mid-sized European microlenders, to be checked against your own data.
Replace the core or add a module: the options with numbers
| Option | Upfront cost | Annual cost | Timeline | Main risk |
|---|---|---|---|---|
| Status quo with collection spreadsheets | 0 EUR | staff time and losses | none | PAR stays high |
| New lending core (market estimate) | 300,000 to 1,000,000 EUR | 15 to 20 % of licence | 12 to 18 months | heavy migration |
| Vendor collections module (market estimate) | 60,000 to 150,000 EUR | 15,000 to 30,000 EUR | 4 to 6 months | partial integration |
| Custom build, Dutch agency (market estimate) | 100,000 to 300,000 EUR | 15,000 to 40,000 EUR | 6 to 9 months | budget overrun |
| Custom loan module, Kolonell (complex app) | 7,000,000 to 15,000,000 FCFA (10,670 to 22,870 EUR) | maintenance 120,000 FCFA/month, about 2,200 EUR/yr | 14 to 18 weeks | quality of existing data |
The custom module reads core data (clients, loans, payments) through an API or scheduled export and adds what is missing: flexible schedules, simple scoring, collections workflows, payment links and dashboards.
What a useful loan module includes
- Flexible schedules: weekly, monthly or seasonal, with grace periods.
- Graduated collections: messages at D-3, D+1 and D+7, then a call task for the officer, then a field visit.
- Digital repayments: SEPA direct debit and iDEAL payment links, matched automatically to the instalment.
- Regulatory and investor reporting: monthly reports pre-filled, PAR by branch, officer and product, covenant ratios.
- Loan officer app: works offline at client sites and syncs when the connection returns.
Mini case study
Illustrative example: Femke, head of operations at a microlender in Amsterdam, 12,000 clients, 180 million EUR outstanding, PAR30 at 8 %. If the module lowers PAR30 by 2 points, 3.6 million EUR return to the performing portfolio. Assuming a quarter of PAR ends as a loss, that is 900,000 EUR of losses avoided per year.

Module cost: 15,000,000 FCFA (22,870 EUR) plus about 2,200 EUR of annual maintenance, around 25,000 EUR in year one. Even if only a tenth of the expected gain materialises, payback comes within the first quarter, not counting the time saved on monthly reporting, estimated at 50 person-days a year.
FAQ
Do we need to replace our core system to lower PAR30?
Not necessarily: most slippage comes from late follow-up and ill-fitting schedules, which a connected module can fix. A full replacement costs 300,000 to 1,000,000 EUR and 12 to 18 months, against 10,670 to 22,870 EUR and about 4 months for a Kolonell module.
Does the module produce regulatory reports?
It can pre-fill monthly reports and compute ratios from core data. Final sign-off stays with your finance team, but preparation time drops from 4 to 6 days to under one day.
Can borrowers repay by iDEAL and direct debit?
Yes, integrating a Dutch payment service provider for iDEAL links and SEPA direct debit takes 3 to 5 weeks. Each payment is matched automatically to the borrower's instalment.
Does the officer app work without a connection?
Yes, it stores visits, collections and photos offline and syncs as soon as a connection is available. A standard tablet around 300 EUR is enough.
Is our data protected?
The module encrypts data in transit and at rest, logs every access and is built for GDPR compliance, with hosting in the EU. Access is role-based with two-factor authentication.
