The verdict in three sentences
Pool maintenance is a business of recurrence: weekly visits, regular dosing, monthly contracts. Paper tracking loses the thread of readings and feeds green-water disputes the client contests. An app schedules the routes, records the pH/chlorine log with before/after photos and bills the contract via mobile money — without missing the repair upsell.
Paper tracking vs a route app
The problem isn't the technical work — it's proof of service and dosing consistency across 25 to 45 pools.
| Criterion | Paper tracking | Vertical app |
|---|---|---|
| Weekly scheduling | Manual diary | Auto-generated routes |
| pH/chlorine reading | Misplaced sheet | Timestamped log per pool |
| Proof of service | Disputable | Before/after photo |
| Product restock alert | Surprise shortage | Low-threshold flagged |
| Monthly contract | Forgotten follow-up | Recurring mobile money billing |
| Green-water disputes | Frequent | -30 % thanks to the log |
The chemical log isn't administrative trivia: it's the argument that ends a dispute when a client blames the provider for water gone green.
Contracts, MRR per pool and upsell
As a 2026 order of magnitude, a monthly maintenance contract runs between 40,000 and 120,000 FCFA (roughly 61-183 EUR) by pool size and frequency.
| Module | Gain | MRR / effect per pool |
|---|---|---|
| Auto route scheduling | -2 h/week coordination | Capacity +5-8 pools/technician |
| pH/chlorine log | Disputes -30 % | Hotel contracts secured |
| Before/after photo | Undeniable proof | Higher client retention |
| Restock alert | Zero shortage | Service continuity |
| Recurring billing | Collection on fixed date | 40,000-120,000 FCFA/month/pool |
| Pump/filter upsell | One-click quote | Additional one-off revenue |
A book of 40 pools at 70,000 FCFA/month is 2,800,000 FCFA in monthly recurring revenue — 33,600,000 FCFA/year made predictable.
Mini case study
Fatou runs a pool maintenance firm in Dakar serving hotels and residences, with 35 pools under contract at 70,000 FCFA/month = 2,450,000 FCFA in monthly recurring revenue. On paper she lost ~2 contracts per quarter over unproven green-water disputes, roughly 1,680,000 FCFA/year lost. With the pH/chlorine log and before/after photos, disputes drop 30 % and she keeps those contracts. She adds a pump-repair upsell worth ~150,000 FCFA/month. Result: stabilized revenue and roughly +1,800,000 FCFA/year.

FAQ
Can the technician record readings offline?
Yes. The pH/chlorine log and photos are captured offline at the poolside, then sync when the signal returns — handy in poorly covered residences.
How does the chemical log reduce disputes?
Every visit stores the pH/chlorine values, time and a before/after photo. That proof cuts green-water disputes by about 30 % because the client sees the real maintenance history.
How does recurring billing work?
The monthly contract (40,000-120,000 FCFA) is billed automatically on a fixed date, paid via Wave or Orange Money, with built-in reminders on late payment.
Can we manage the repair upsell?
Yes, a pump/filter quote is generated in one click from the pool record, adding one-off revenue on top of the maintenance contract.
How many pools can one technician handle with the app?
Where paper caps out around 25-30 pools, automated scheduling lets one technician cover 35-45 without quality loss.
