The verdict in three sentences
An Excel sheet works up to 15-20 units; beyond that, the time lost on reminders and receipts exceeds the cost of a dedicated app. A custom rental app (mobile money collection, automatic PDF receipts, scheduled reminders) saves several days a month and cuts arrears by 3 to 8 points. For a portfolio of 40 to 200 units, payback is measured in a few months.
Excel vs dedicated app
| Criterion | Excel / paper | Rental management app |
|---|---|---|
| Rent collection | Manual, cash | Automated Wave / Orange Money |
| Receipt | Manual entry | PDF generated and sent auto |
| Arrears reminder | By hand, forgotten | Automatic SMS/WhatsApp |
| Arrears tracking | Difficult | Real-time dashboard |
| Owner reporting | None | Automatic monthly statement |
| Error risk | High | Low |
| Monthly time (80 units) | 3 to 5 days | Under 1 day |
Cost, content and ROI by portfolio size
| Portfolio size | App cost (order of magnitude) | Time saved/month | Arrears avoided/year (est.) |
|---|---|---|---|
| 20 units | 1,500,000 FCFA | 1 to 2 days | 600,000 FCFA |
| 50 units | 2,500,000 FCFA | 2 to 3 days | 1,800,000 FCFA |
| 100 units | 3,200,000 FCFA | 4 to 5 days | 4,000,000 FCFA |
| 200 units | 4,000,000 FCFA | 8 to 10 days | 9,000,000 FCFA |
Arrears-avoided estimates assume an average rent of 150,000 FCFA and roughly a 4-point reduction in the arrears rate thanks to automatic reminders. Monthly maintenance: 50,000 to 150,000 FCFA.
Key app features
The app centralises properties, tenants, leases and rent. Each month it sends a Wave/Orange Money payment link to the tenant, generates the PDF receipt on receipt, and auto-chases late payments at D+3 and D+7. The owner gets a monthly statement with collections, arrears and occupancy rate. The manager tracks everything from one dashboard.

Mini case study
Moussa manages 100 units in Dakar and Mbour, average rent 150,000 FCFA, so 15,000,000 FCFA collectable/month. His arrears rate was 9 %, i.e. 1,350,000 FCFA/month stuck. After the app, automatic reminders bring it to 5 %, freeing 600,000 FCFA/month, or 7,200,000 FCFA/year. The app at 3,200,000 FCFA + maintenance (1,200,000 FCFA/year) is paid back in under 8 months, not counting the 4-5 workdays recovered each month.
FAQ
Does the tenant need to install an app? No. They get a simple payment link by SMS or WhatsApp and pay via Wave or Orange Money in seconds, with no account or install.
Are the receipts compliant? Yes, the PDF receipt carries the legal details (landlord, tenant, period, amount, payment date) and a unique number. It is archived and can be resent at any time.
What happens on a missed payment? The app flags the unit as late, triggers automatic reminders at D+3 and D+7, and alerts the manager. The owner sees the arrears in their monthly statement in real time.
Can it handle multiple owners? Yes. A management firm can separate accounts per owner, with distinct statements and payouts, ideal for an agency managing on behalf of third parties.
