The verdict in three sentences
For a utility with 45,000 customers, every point of collection rate gained is worth about 135,000 USD a year, which makes a 350,000 USD system profitable in under 18 months. Combining geolocated tablet meter reading, prepaid meters and Orange Money and MTN MoMo mobile payment attacks the 22% commercial losses head on. A serious project in Guinea costs 250,000 to 450,000 USD, delivered in 6 to 8 months in phases.
Where an African utility's revenue leaks
Losses at a water and power distributor in Conakry and inland Guinea are rarely purely technical. They come from estimated readings, bills never delivered, unregistered connections and cash collection that is hard to control.
| Loss source (2026 order of magnitude) | Current situation | Target with the new system |
|---|---|---|
| Estimated readings for lack of meter reading | 30% of meters | under 5% |
| Undelivered bills | 12% | 0% (SMS and WhatsApp) |
| Unbilled connections | 4 to 6% of actual customers | detected by GPS cross-checks |
| Overall commercial losses | 22% | 10 to 12% |
| Collection rate | 68% | 85% |
| Average collection delay | 75 days | 30 days |
| Share of mobile payments | 15% | 60% |
On an average bill of 25 USD a month (about 215,000 GNF), billed revenue reaches 13.5 million USD a year. Moving from 68% to 85% collection means 2.3 million USD more cash every year.
Modules and their cost
| Module | Function | Indicative budget |
|---|---|---|
| Customer and meter registry | geolocated records, contracts, social and commercial tariffs | 35,000 to 60,000 USD |
| Offline mobile meter reading | Android tablet, photo of the reading, GPS, deferred sync | 40,000 to 70,000 USD |
| Billing engine | water and power tariff bands, taxes, penalties, credit notes | 50,000 to 90,000 USD |
| Prepaid meters | STS token generation, credit sales, top-up tracking | 45,000 to 80,000 USD |
| Mobile payment and branches | Orange Money, MTN MoMo, branch tills, automatic reconciliation | 30,000 to 55,000 USD |
| Collection and disconnection | SMS reminders, disconnection lists, payment plans | 25,000 to 45,000 USD |
| Dashboards and regulator reporting | losses by zone, network efficiency, indicators for the regulator | 25,000 to 50,000 USD |
The total ranges from 250,000 USD for a tight scope to 450,000 USD with full prepayment and advanced reporting. Cloud hosting and maintenance then run 35,000 to 60,000 USD a year.
A 6 to 8 month rollout plan
| Phase | Duration | Deliverable |
|---|---|---|
| Audit and clean-up of the customer file | 6 weeks | reliable, geolocated customer base |
| Mobile reading and billing | 10 weeks | first billing cycle on a pilot zone |
| Mobile payment and collection | 6 weeks | payments reconciled automatically |
| Prepayment | 6 weeks | first 5,000 prepaid meters live |
| Rollout and training | 4 to 6 weeks | 45,000 customers, 60 readers and agents trained |
The pilot zone, ideally a Ratoma neighbourhood or a mini-grid in Forest Guinea, validates tariffs and reading quality before full switchover.

Mr Camara, commercial director of a mini-grid and water supply operator in Guinea, manages 45,000 customers billed 13.5 million USD a year. His collection rate is stuck at 68%. With a 350,000 USD system plus 45,000 USD maintenance, a cautious climb to 78% in year one brings in 13.5M x 10% = 1.35 million USD extra. The project pays for itself in about 4 months at full effect, and the 85% target adds another 950,000 USD a year.
FAQ
What budget should a utility plan for water and power billing software in Guinea?
Budget 250,000 to 450,000 USD depending on modules, for 30,000 to 80,000 customers. Annual maintenance sits between 35,000 and 60,000 USD.
Does meter reading work in areas without coverage?
Yes, the app stores up to 2,000 readings offline per tablet, with photo and GPS, then syncs back in coverage. A rugged tablet costs around 250 to 400 USD.
Are existing prepaid meters compatible?
STS-standard meters are supported, which covers most of the installed base in West Africa. Interfacing with a proprietary vending system adds 3 to 5 weeks.
Can we collect through Orange Money and MTN MoMo?
Yes, both operators are integrated with automatic payment reconciliation. Merchant fees run around 1 to 2% per transaction depending on the negotiated contract.
How long does the project take?
The standard timeline is 6 to 8 months, with a first billing cycle on the pilot zone around month four.
