The verdict in three sentences
A West African municipality collecting market fees and public space occupancy taxes in cash, with paper receipt books, loses a large share of its revenue before it reaches the municipal treasurer. A revenue collection platform combining a geolocated taxpayer census, digital receipts and mobile money payments costs 150 to 400 million GNF (about 13,000 to 35,000 GBP) in the budgets observed in 2026. Donor-funded projects, many of them designed and monitored from London, often target a 20 to 50% increase in revenue, provided the census is rigorous and collectors are equipped and supervised.
What the software must cover, using Conakry as the reference case
For programme managers at donors, development finance institutions and consultancies in London, Conakry is a typical case. The secretary general of a commune such as Matam, Ratoma or Kaloum manages several revenue streams: market stall fees, public space occupancy taxes, business licences and local contributions, parking and billboard fees. Guinea's Local Authorities Code gives collection to the commune under the control of the municipal treasurer, so every Guinean franc collected must be traceable, which also matters for donor audit requirements.
| Module | Common situation today | With the software | Indicator to track |
|---|---|---|---|
| Taxpayer census | Incomplete paper lists | Geolocated record, photo, activity, location | Number of active taxpayers registered |
| Notices | Manual, irregular | Notices generated by tax type and area | Share of notices issued on time |
| Field collection | Receipt books, cash | Digital receipt printed or sent by SMS | Gap between receipts and deposits |
| Mobile payment | None | Orange Money or MTN MoMo, unique reference | Share of revenue paid cashless |
| Collector monitoring | Random checks | Geolocated rounds, targets per collector | Revenue per collector per day |
| Mayor's dashboard | Quarterly report | Real-time revenue by market and tax | Monthly collection rate |
Collection devices must work offline, as coverage is patchy in some covered markets, and print a receipt in under 10 seconds so rounds are not slowed down.
Budget, funding and expected return
| Item (2026 order of magnitude) | Range in GNF | Approx. GBP | Note |
|---|---|---|---|
| Platform development and setup | 80 to 220 million GNF | 7,000 to 19,000 GBP | Depends on number of taxes and integrations |
| Field census (3,000 to 8,000 taxpayers) | 30 to 80 million GNF | 2,600 to 7,000 GBP | Enumerators, 6 to 10 weeks |
| Devices with printer (20 to 40 collectors) | 25 to 70 million GNF | 2,200 to 6,100 GBP | 1.2 to 1.8 million GNF per device |
| Training and change management | 10 to 30 million GNF | 900 to 2,600 GBP | Collectors, treasurer, elected officials |
| Total observed project | 150 to 400 million GNF | 13,000 to 35,000 GBP | Often co-financed by a donor |
| Annual hosting and maintenance | 15 to 40 million GNF | 1,300 to 3,500 GBP | Must be in the municipal budget |
For comparison, at Kolonell a complex application of this kind falls in the 10,670 to 22,870 EUR and above range (7 to 15 M FCFA and above), excluding the field census and hardware, which remain managed locally.
Mini case study
Mamadou, secretary general of a commune in Conakry (illustrative persona), collects about 2 billion GNF a year in market and occupancy taxes. A baseline study estimates that 35% of the money collected never reaches the municipal treasury.
- Prudent target: 25% revenue increase, or 500 million GNF more per year.
- Project cost: 300 million GNF, 60% covered by a donor, leaving 120 million GNF for the commune.
- Maintenance: 25 million GNF per year.
The commune's share is covered in about 3 months of additional revenue. Even with an increase limited to 10%, or 200 million GNF, the project pays back within the year, a strong case for a donor results framework.

FAQ
How much does municipal revenue collection software cost?
Budgets observed in 2026 range from 150 to 400 million GNF (about 13,000 to 35,000 GBP), census and devices included. The platform alone usually accounts for half of that amount.
Is mobile payment realistic for market traders?
Yes, Orange Money and MTN MoMo are widely used in Conakry. Targeting 20 to 30% cashless payments in the first year is reasonable, with cash still traced by digital receipt.
How do you prevent collector fraud?
Each receipt carries a unique number and a geolocation, and daily deposits are reconciled automatically. Gaps above 2% trigger an alert to the treasurer.
Does the census need to be redone every year?
Continuous updates are enough: collectors add new traders during their rounds. A full verification campaign every 2 to 3 years remains useful.
How long does it take to launch?
Plan 4 to 6 months: 2 to 3 months of development alongside the census, then a pilot on one market for 6 to 8 weeks before rolling out to the whole commune.
