The verdict in three sentences
For a water service operator with 18,000 customers in Antananarivo, 35% non-revenue water and a collection rate below 75% weigh far more than the price of software. Billing software with offline smartphone meter reading, prepaid meters, mobile money payment and a leak map costs MGA 80 to 180 million (about EUR 16,000 to 36,000) in 2026, with a 5-month timeline. Gaining 10 points of non-revenue water and 15 points of collection pays back the project in under a year.
Where a Malagasy water operator's losses come from
Non-revenue water has three sources: physical losses (leaks on an ageing network), commercial losses (stuck meters, illegal connections, reading errors) and volumes consumed but never collected. With paper reading books re-keyed at the office, 6 to 10% of readings are wrong or estimated, and disputed bills pile up.
The expected features:
- Offline smartphone meter reading: geolocated rounds, meter photo, reading consistency checks, sync when back online.
- Billing: tiered tariffs by category (domestic, commercial, standpipe), connection fees, penalties.
- Prepaid meters: token generation, top-up tracking, low-credit alerts.
- Mobile money payment: MVola, Orange Money and Airtel Money with automatic posting to the bill.
- Collection: SMS reminders, payment plans, disconnection and reconnection orders.
- Leak map and water balance: volumes produced versus volumes billed per sector.
| Module | Indicative 2026 cost (MGA excl. VAT) | Timeline | Expected effect |
|---|---|---|---|
| Customer register and tiered billing | 20,000,000 to 40,000,000 | 6 to 8 weeks | Bills without re-keying |
| Offline meter reading app | 15,000,000 to 35,000,000 | 5 to 7 weeks | Reading errors under 1% |
| Prepaid meters | 12,000,000 to 30,000,000 | 4 to 6 weeks | Cash before consumption |
| MVola, Orange Money, Airtel Money payment | 10,000,000 to 25,000,000 | 4 to 5 weeks | 60% of payments without a counter |
| Collection and disconnections | 8,000,000 to 20,000,000 | 3 to 4 weeks | Arrears tracked by age |
| Leak map and sector balance | 15,000,000 to 30,000,000 | 4 to 6 weeks | Loss-making sectors identified |
The total ranges from MGA 80 million (about EUR 16,000) for billing, reading and payment to MGA 180 million (about EUR 36,000) with prepayment and the leak map. Budget MGA 2 to 5 million per month for hosting, SMS and maintenance.
Before and after: non-revenue water and collection
Take an average monthly bill of MGA 30,000. 18,000 customers represent about MGA 6.5 billion in billed revenue a year. Each collection point is therefore worth about MGA 65 million.
| Indicator (2026 order of magnitude) | Before | After 12 months |
|---|---|---|
| Non-revenue water | 35% | 24 to 27% |
| Collection rate | 70 to 75% | 88 to 92% |
| Wrong or estimated readings | 6 to 10% | Under 1% |
| Time from reading to bill | 10 to 15 days | 1 to 2 days |
| Billing complaints per month | 400 to 600 | 80 to 150 |
| Share of payments via mobile money | 15% | 55 to 65% |
| Arrears over 90 days | MGA 1.2 to 1.8 billion | MGA 400 to 600 million |
Postpaid, prepaid or mixed: which meter model
| Model | Cost per meter (MGA) | Typical collection | Suited to |
|---|---|---|---|
| Mechanical postpaid, paper reading | 120,000 to 180,000 | 65 to 75% | Current situation, to avoid |
| Mechanical postpaid, smartphone reading | 120,000 to 180,000 | 85 to 90% | Regular households |
| Token prepaid | 450,000 to 750,000 | 97 to 99% | Large debtors, shops |
| Smart connected meter | 900,000 to 1,500,000 | 95 to 99% | Large consumers, pilots |
| Mixed (90% postpaid, 10% prepaid) | Average 170,000 to 240,000 | 90 to 93% | Recommended for 18,000 customers |
The mixed model is the most profitable: fitting prepaid meters for the 1,500 to 2,000 customers most in arrears solves much of the debt without equipping the whole base.

Hery, director of a water operator with 18,000 customers in Antananarivo, collects 72% of his MGA 6.5 billion billed. He invests MGA 140 million in software and MGA 3.5 million per month in maintenance, MGA 182 million in year one, plus 1,500 prepaid meters at MGA 600,000, MGA 900 million.
After 12 months, collection reaches 89%: 17 more points, about MGA 1.1 billion of extra cash. Reducing non-revenue water from 35% to 26% adds nearly MGA 700 million of billed volumes. For a total investment of MGA 1.08 billion, the gain exceeds MGA 1.8 billion in the first year.
FAQ
How much does water billing software cost in Madagascar in 2026?
Budget MGA 80 to 180 million excl. VAT for 15,000 to 25,000 customers, depending on prepayment and the leak map. Operations then cost MGA 2 to 5 million per month.
Does meter reading work without a network?
Yes, the app stores readings and photos offline then syncs when the network returns. A reader covers 120 to 180 meters a day instead of 80 to 100 on paper.
Can we collect via MVola, Orange Money and Airtel Money?
Yes, with a unique customer reference and automatic posting. Negotiated merchant fees are around 1 to 2% of the amount.
How does the software help reduce non-revenue water?
It compares produced and billed volumes per sector, flags zero-consumption meters and sudden gaps. An 8 to 11 point gain is a realistic order of magnitude in year one.
Does the software adapt to tariffs set by the regulator?
Yes, tiers, categories and fees are configurable without development. A tariff revision goes live in less than a day.
