The verdict in three sentences
Water and gas delivery in Thiès is fundamentally a subscription business: same customers, same cycles, high predictability — yet run by phone, it leaks everywhere. A dedicated app that automates recurring orders, optimizes rounds and collects via recurring mobile money raises retention by about 30 % and cuts fuel by 15 %. The 2026 build sits between 1,200,000 and 2,400,000 FCFA, versus 12,000 to 28,000 FCFA/month in SaaS.
Phone calls vs subscription app + routing
The phone doesn't remember consumption cycles, doesn't plan rounds and doesn't collect in advance. Here's what a dedicated app changes.
| Criterion | Phone-based management | Subscription app + routing |
|---|---|---|
| Recurring order | Customer must call back | Automatic per cycle |
| Customer retention | Baseline, volatile | +30 % roughly |
| Round planning | Manual, approximate | Optimized by zone |
| Fuel cost | Reference | -15 % via routing |
| Payment | Cash on delivery | Recurring mobile money |
| Courier tracking | None | Real time |
| Deliveries/day/courier | 30 to 80 | 40 to 120 |
| Missed restocks | Frequent | Automatic alerts |
The gain comes from the recurrence + routing pair: you fill each round better and stop losing the customer who "forgets" to reorder.
Cost, basket and volume: the 2026 figures
| Indicator | 2026 order of magnitude |
|---|---|
| Custom app build | 1,200,000 to 2,400,000 FCFA |
| Equivalent monthly SaaS | 12,000 to 28,000 FCFA/month |
| Hosting + maintenance | 20,000 to 50,000 FCFA/month |
| Average recurring basket | 3,000 to 12,000 FCFA |
| Deliveries/day/courier | 40 to 120 |
| Fuel saving | ~15 % |
| Retention lift | ~30 % |
| Project delivery time | 6 to 9 weeks |
2026 order of magnitude: once you exceed ~2 couriers and a few hundred subscribers, routing and upfront collection justify the build.
Mini case study
Ibrahima, who runs a water and gas depot in Thiès, serves 250 subscribed households, average basket 6,000 FCFA, weekly cycle. Theoretical monthly revenue: 250 × 6,000 × 4 = 6,000,000 FCFA. With phone management, ~15 % of customers "skip" a cycle by oversight: loss ~900,000 FCFA/month. With the app and recurring orders, he recovers half (~450,000 FCFA/month) and saves 15 % on fuel. His app at 1,800,000 FCFA pays back in ~4 months.

How does recurring mobile money payment work?
The customer authorizes a Wave/Orange Money charge each cycle, or receives an automatic payment link. This secures the 3,000 to 12,000 FCFA recurring basket without handling cash every visit.
Is route optimization really useful in town?
Yes: grouping deliveries by zone reduces empty kilometers. For a courier making 40 to 120 deliveries/day, fuel savings run around 15 %.
What about customers without a smartphone?
The agent enters their recurring orders in the back office. The customer gets a confirmation SMS; they benefit from routing and regularity without installing an app.
How long to deploy?
Expect 6 to 9 weeks: catalog, subscriptions, routing, recurring payment and a courier app.
Can water and gas live in the same app?
Yes, they are two catalogs with different cycles (water often weekly, gas monthly). The app orchestrates both in one round.
