The verdict in three sentences
A developer in Abidjan selling several programmes on instalment plans cannot run client payment schedules on Excel without piling up arrears and errors. A custom platform at 12,000,000-28,000,000 FCFA centralises programmes, sales, schedules and a buyer portal. The target gain is direct: -25 % arrears through automated tracking and reminders.
Excel vs dedicated platform: the real cost in 2026
Many Ivorian developers start on spreadsheets. The hidden cost is not the licence — it is arrears, schedule errors and admin time. 2026 orders of magnitude for a developer running 2 to 6 programmes.
| Criterion | Excel spreadsheet | Custom platform |
|---|---|---|
| Software cost | ~0 FCFA | 12,000,000-28,000,000 FCFA |
| Schedule tracking | Manual, risky | Automatic |
| Arrears rate | 15-22 % | 10-14 % |
| Client reminders | Missed | Scheduled (SMS/email) |
| Buyer portal | None | Included |
| Schedule errors | Frequent | Near zero |
| Management reporting | 2-3 days/month | Real time |
On a 50-home programme at 35,000,000 FCFA, moving from 20 % to 14 % arrears secures 105,000,000 FCFA more collected — far beyond the platform's cost.
What the platform secures on payments
The core value is the instalment payment schedule: each buyer pays in several tranches, and every un-chased delay weakens the programme's cash flow.
| Item | Without platform | With platform | Gain |
|---|---|---|---|
| Arrears on instalments | 15-22 % | 10-14 % | -25 % relative |
| Reminder delay | 15-30 days | Automatic D+3 | Cash +20 days |
| Per-buyer tracking | Shared sheet | Dedicated portal | 0 balance dispute |
| Admin time/month | 12-18 days | 4-6 days | ~1,500,000 FCFA/month |
| Cash visibility | Monthly | Real time | Faster decisions |
Recovering 8-12 admin days per month, at ~130,000 FCFA/loaded day, is over a million FCFA saved monthly, on top of arrears avoided.
Why Excel does not scale for a developer

The spreadsheet remains the natural starting tool, but it quickly hits its limits once an Ivorian developer goes beyond one programme and a few dozen buyers. The first problem is the absence of alerts: an Excel schedule chases no one, so a payment delay is only spotted at the next manual check, often 15 to 30 days too late. The second problem is reliability: a broken formula, an overwritten row or an outdated file version is enough to distort a programme's entire cash tracking, with direct consequences on payments to contractors. The third problem is sharing: without a buyer portal, every client calls or visits the office to learn their balance, generating disputes and tying up sales staff. A dedicated platform solves all three by centralising schedules, triggering automatic SMS and email reminders, and giving each buyer a transparent view of their situation. In 2026, with the spread of Wave and Orange Money in Côte d'Ivoire, integrating mobile payment directly into the schedule even enables automatic collection and reconciliation, removing manual entry errors and speeding up payment recognition.
Mini case study
Mr Koné runs a development company in Abidjan: 3 active programmes, 140 homes being sold, average price 32,000,000 FCFA, payment in 6 tranches. On Excel, his arrears rate reaches 20 %, meaning on an annual pipeline of ~2,100,000,000 FCFA a tight shortfall of several hundred million. A 22,000,000 FCFA custom platform that brings arrears to 14 % secures ~6 collection points, or ~126,000,000 FCFA better recovered over the year. Return on investment is reached within the first quarter of operation.
