The verdict in three sentences
For a Kigali property agency managing 450 units for landlords living in Belgium, Canada or the United States, the spreadsheet no longer holds: late statements, forgotten receipts, landlord calls at midnight Kigali time. At Kolonell, custom rental management software ranges from 4M to 7M FCFA (6,100 to 10,670 EUR) and is delivered in 10 to 14 weeks. With automatic SMS reminders and MTN MoMo, Airtel Money and bank collections reconciled automatically, agencies commonly see 15 to 25% fewer arrears (2026 ballpark).
Where the agency loses time and money
A diaspora landlord judges the agency on two things: regular payouts and a clear monthly statement. Both tasks are still mostly manual.
| Task | Current method | 2026 hidden cost |
|---|---|---|
| Rent collection | Cash, MTN MoMo, Airtel Money, bank transfer | 2 to 3 days of reconciliation per month |
| Receipts | Word or receipt book, sent on WhatsApp | 450 documents a month, frequent gaps |
| Reminders | Property manager phone calls | 30 to 40 calls per week |
| Landlord statement | Excel then PDF | 1 to 2 days, calculation errors |
| Diaspora payouts | Manual international transfer | 5 to 10 day delays |
| Maintenance tracking | Photos on WhatsApp | No expense traceability |
| Arrears rate | Noticed at month end | 10 to 15% of rents late |
With an average rent of 400,000 RWF, 450 units represent 180 million RWF collected per month. A 12% arrears rate ties up 21.6 million RWF, and every delay pushes back the landlord payout.
Modules and budget
Custom software makes sense here because international tools handle neither mobile money nor local practice (2 to 3 month deposits, rent paid quarterly in advance, split payments).
| Module | Function | Budget share |
|---|---|---|
| Units, leases and tenants | Term, deposit, due dates, reviews | 15% |
| Multi-channel collection | MTN MoMo, Airtel Money, bank transfer, cash at the desk | 20% |
| Automatic receipts | PDF generated on payment, sent by SMS or WhatsApp | 10% |
| SMS reminders | D+3, D+7, D+15, escalation to manager | 10% |
| Landlord statements and payouts | Rent, fees, repairs, balance in RWF and EUR or USD | 20% |
| Online landlord area | Statements, photos, repair invoices | 15% |
| Agency dashboard | Arrears, vacancy, monthly fees | 10% |
The low end (4M FCFA) covers units, collections, receipts, reminders and PDF statements. The high end (7M FCFA) adds the online landlord area, repair tracking and batched payouts. Standard maintenance is 75,000 FCFA per month. Tenant data falls under Rwanda's Law No. 058/2021 on personal data protection: register with the national authority and restrict access by role.
Typical 10 to 14 week timeline
Weeks 1 and 2: scoping, migration of the existing spreadsheet and receipt templates. Weeks 3 to 9: development by module, collections and receipts first. Weeks 10 and 11: import of the 450 units and test on a real rent month. Weeks 12 to 14: landlord area launch and manager training. Go live at the start of a month, right after a statement, to compare figures over a full cycle.

Jean-Paul, managing director of a property agency in Kigali (illustrative scenario), manages 450 units, collects 180 million RWF a month and charges 8% management fees. Arrears stand at 12%. If automatic reminders cut them by 20%, an extra 4.32 million RWF is collected each month, or 345,600 RWF in additional fees. He also saves 4 days of admin work, valued at 400,000 RWF. Monthly gain: about 745,600 RWF (roughly 470 EUR). For software at 5.5M FCFA (8,390 EUR) plus 75,000 FCFA maintenance, payback arrives around 24 months, before counting new mandates from landlords reassured by an online statement.
FAQ
Can tenants pay with MTN MoMo and Airtel Money?
Yes, each payment is matched to its lease automatically through a unique reference. Merchant fees, around 1 to 2%, stay below the cost of handling cash.
What do SMS reminders cost?
Allow 15 to 25 RWF per SMS. For 450 units and up to 3 reminders, the budget stays under 35,000 RWF a month.
Can a landlord in Brussels see the statement in euros?
Yes, the statement shows the balance in RWF and its EUR or USD equivalent at the rate of the day. The PDF is available on the 5th of each month.
Can we migrate our Excel data?
Yes, importing units, leases and balances is planned at scoping. For 450 units, migration takes 3 to 5 days including checks.
Why not use an international SaaS?
International tools cost 3 to 8 USD per unit per month, so 1,350 to 3,600 USD a month for 450 units, without mobile money. Custom software pays for itself in 2 to 3 years and remains your property.
