The verdict in three sentences
A spa or hammam in Saly lives off a diaspora and hotel clientele that books remotely, cancels easily and speaks several languages. Without a multi-therapist agenda or deposit, cabins sit empty on slots that could have sold three times over. An appointment app with a card/Wave deposit and D-1 reminders cuts no-shows by about 60 % for a 2026 build of 1,000,000 to 2,000,000 FCFA.
Paper register vs multi-therapist app
The paper register can't manage several therapists in parallel, doesn't follow up and can't collect a remote deposit. Here's the gap.
| Criterion | Paper register | Multi-therapist app |
|---|---|---|
| Per-cabin/therapist agenda | Confusing | Dedicated view per therapist |
| Remote booking | Phone only | Online 24/7 |
| Deposit | Impossible remotely | Card/Wave automated |
| No-show | 30 to 45 % | 12 to 18 % |
| Client reminder | Manual or absent | SMS/WhatsApp D-1 |
| Multilingual (FR/EN) | No | Yes |
| Fill rate | Reference | +25 % |
| Treatment history | Scattered | Client record |
For a diaspora clientele booking from Paris or Milan, online booking with a card deposit is decisive: without it, booking stumbles on time-zone gaps and phone tag.
Treatments, therapists and fill rate: 2026 figures
| Indicator | 2026 order of magnitude |
|---|---|
| Custom app build | 1,000,000 to 2,000,000 FCFA |
| Monthly SaaS | 9,000 to 22,000 FCFA/month |
| Treatment (massage, hammam, scrub) | 12,000 to 45,000 FCFA |
| Therapists managed | 3 to 8 |
| No-show drop | ~60 % |
| Fill-rate lift | +25 % |
| Deposit requested | 30 to 50 % |
| Delivery time | 5 to 7 weeks |
2026 order of magnitude: on an average 25,000 FCFA treatment, every cabin recovered per day and per therapist weighs heavily for a spa open 6 days a week.
Mini case study
Fatou, who runs a 4-therapist spa in Saly, offers 8 slots/day/therapist, average treatment 25,000 FCFA. Capacity: 32 treatments/day. At 60 % fill and 35 % no-show, she nets ~12 treatments/day = 300,000 FCFA/day. With the app (deposit + reminders), fill rises to 75 % and no-show to 14 %: ~20 net treatments/day = 500,000 FCFA/day, i.e. +200,000 FCFA/day. Over 26 days, +5,200,000 FCFA/month. Her app at 1,600,000 FCFA pays back in ~a week and a half.

How does the app manage several therapists?
Each therapist has their own agenda and cabins; the app prevents collisions and shows only genuinely available slots. It comfortably handles 3 to 8 therapists.
Can diaspora clients pay by card?
Yes: bank card for international, Wave/Orange Money for local. A 30 to 50 % deposit secures the slot regardless of the departure country.
Are reminders multilingual?
Yes, FR and EN at minimum, via SMS and WhatsApp the day before (D-1). It's a key driver of the ~60 % no-show reduction.
How long to deliver the app?
Between 5 and 7 weeks, including a multi-therapist agenda, card/Wave deposit and automatic reminders.
Can we sell gift cards and packages?
Yes, the app handles multi-treatment packages and prepaid gift cards — highly popular with hotel and diaspora clients. A package secures several visits in advance.
