The verdict in three sentences
An Accra clinic booking by phone loses 25 to 35% of slots to no-shows and double-booking. A booking app (multi-doctor calendar, SMS/WhatsApp reminders, mobile money deposit) costs 2.2 to 4.5M FCFA over 5 to 7 weeks, versus 45,000 to 120,000 FCFA/month for a Calendly-type SaaS. Tuned well, it cuts no-shows from 30% to 9% and pays back in about 7 months.
Cost per feature in 2026
| Feature | Scope | Cost FCFA 2026 |
|---|---|---|
| Multi-doctor calendar | Slots, blocks, leave | 600,000 - 1,100,000 |
| SMS/WhatsApp reminders | D-1, D-2, confirmation | 500,000 - 900,000 |
| MoMo deposit | Prepayment, anti no-show | 500,000 - 1,000,000 |
| Patient portal | 24/7 online booking | 400,000 - 800,000 |
| Auto waitlist | Fills cancellations | 300,000 - 600,000 |
| Dashboard | No-show rate, fill rate | 300,000 - 500,000 |
The core (calendar + reminders + deposit) fits 2.2 to 3.2M FCFA.
International SaaS vs custom
| Criterion | Calendly-type SaaS | Custom app |
|---|---|---|
| Upfront cost | 0 | 2,200,000 - 4,500,000 |
| Monthly cost | 45,000 - 120,000 | 60,000 (maintenance) |
| Local WhatsApp reminders | Limited / paid | Native |
| Wave / MoMo deposit | No | Yes |
| Local language & UX | Standard | Custom |
| 36-month total | 1,620,000 - 4,320,000 | ~4,360,000 |
SaaS wins over 12 months; custom takes the lead thanks to the MoMo deposit that genuinely cuts no-shows.

Mini case study
Dr Mensah shares a clinic in Accra with 2 colleagues: 3 doctors, ~90 consultations/week targeted but 30% no-shows. After a 3.2M FCFA app with a 2,000 FCFA MoMo deposit, no-shows drop to 9%. Result: +14 consultations/week, about 450,000 FCFA of extra monthly revenue. The app pays back in 7 months, and the deposit alone deters ghost appointments.
FAQ
Won't the MoMo deposit scare patients off? No: a modest deposit (1,500 to 3,000 FCFA) deducted from the consultation builds commitment without blocking. It's the single most effective lever against no-shows.
Why not just Calendly? International SaaS handles neither Wave/MoMo nor reliable local WhatsApp reminders, and those are exactly the two levers that cut no-shows in Ghana.
How long to build? 5 to 7 weeks, with online booking working by week 4.
Are WhatsApp reminders automatic? Yes, sent at D-2 and D-1 with one-click confirmation; the patient can cancel and free the slot for the waitlist.
What about a solo practice? A trimmed scope at 2.2M FCFA is enough; ROI stays fast once no-shows exceed 20%.
