The verdict in three sentences
A solar mini-grid and water operator with 15,000 customers still billing from paper readings often loses 20 % of revenue to non-payment and reading errors. Custom billing software at FCFA 25 to 55 million (about EUR 38,000 to 84,000) combines prepaid meters, mobile meter reading and mobile money payment (Wave, Orange Money); Singapore-based integrators typically quote USD 120,000 or more for similar scope. Realistic 12-month target: commercial losses cut in half, with payback often under a year.
What utility billing software costs
Private operators (rural mini-grids, water concessionaires, borehole managers) share similar needs: scattered customers, mobile money collection and consumption tracking.
| Module | 2026 budget | Timeline |
|---|---|---|
| Customer and contract management | FCFA 4M to 8M (EUR 6,000 to 12,000) | 1.5 months |
| Tariffs (blocks, flat rates, prepaid) | FCFA 3M to 7M (EUR 4,500 to 10,500) | 1 month |
| Offline mobile reading with meter photo | FCFA 5M to 10M (EUR 7,500 to 15,000) | 2 months |
| Prepaid meter integration (STS tokens, IoT API) | FCFA 6M to 15M (EUR 9,000 to 23,000) | 2 to 3 months |
| Mobile money payment and USSD top-up | FCFA 4M to 9M (EUR 6,000 to 14,000) | 1.5 months |
| Collections, disconnections and dashboards | FCFA 3M to 6M (EUR 4,500 to 9,000) | 1 month |
| Total | FCFA 25M to 55M (EUR 38,000 to 84,000) | 6 to 9 months |
International SaaS platforms for mini-grids usually charge USD 0.5 to 1.5 per meter per month, or USD 90,000 to 270,000 per year for 15,000 customers, without data ownership or adaptation to local practices.
Prepaid or postpaid: the effect on non-payment
Prepaid meters structurally solve non-payment but cost FCFA 25,000 to 60,000 (EUR 38 to 92) per connection. Many operators combine both: prepaid for households, postpaid with mobile reading for large customers.
| Indicator | Paper reading, postpaid | Software + prepaid and mobile money |
|---|---|---|
| Non-payment rate | 20 % | 5 to 10 % |
| Time from reading to invoice | 15 to 30 days | 24 hours |
| Reading errors | 5 to 8 % | Under 1 % |
| Share of mobile money payments | 15 % | 70 to 85 % |
| Collection cost per invoice | FCFA 500 to 1,000 (agent, travel) | 1 % of the amount |
| Visibility on fraud and technical losses | Low | Daily balance by area |
These values are 2026 estimates drawn from comparable operators in West Africa.
Regulatory requirements
The software must produce the reporting data required by the regulator (CRSE for electricity in Senegal, the Energy Market Authority in Singapore) or the water authority, send invoices by SMS and WhatsApp, and comply with data protection law (Senegal's Law 2008-12, Singapore's PDPA). Plan a degraded mode: prepaid top-up must remain possible even if the mobile money API is briefly unavailable.

Moussa, CEO of a solar mini-grid and water operator in the Kaolack region, serves 15,000 customers with billed revenue of FCFA 900 million per year. At 20 % non-payment, he loses FCFA 180 million. Halving those losses recovers FCFA 90 million (about EUR 137,000) per year. The software is quoted at FCFA 42 million plus FCFA 6 million annual maintenance. Payback: about 6 months, excluding prepaid meter hardware.
FAQ
How much does water or energy billing software cost?
Budget FCFA 25 to 55 million (EUR 38,000 to 84,000) depending on prepaid meter integration. A first phase with customers, mobile reading and payment starts around FCFA 15 million.
Can customers pay with mobile money?
Yes, payments are automatically matched to the invoice or generate a top-up token. Fees run around 1 % per transaction.
Does the software work with our existing meters?
Yes if the meters support the STS standard or expose an API. Otherwise, mobile reading with a photo covers conventional meters.
What happens without internet in villages?
The reading app works offline and syncs later. USSD top-up remains available on 2G networks.
What deployment timeline should we expect?
The full software ships in 6 to 9 months. A 6-week pilot on 1,000 customers is recommended.
