The Client
Kambia District Council
Kambia District Council, in northern Sierra Leone, administers property and business taxation for its communities. Like many sub-national governments, it depended on revenue it could not fully see, reliably serve, or cleanly audit.
The Council set out to formalize its property roll, make collection transparent, and produce records that could stand up to an external audit — without exporting sensitive data to third-party systems.
The Challenge
Revenue that couldn't be seen, served, or audited
Rolls lived in spreadsheets. Rate Demand Notices left the office as paper and disappeared — with no proof of delivery when a taxpayer disputed one. Cash moved before it reached a bank, and auditors arrived to a ledger no one could defend.
- • Incomplete property roll and low coverage
- • No evidence a notice was actually served
- • Fragmented, hard-to-reconcile cash collection
- • No audit trail external auditors could trust
The Solution
One platform — roll to receipt to reconciliation
PaMGIS was deployed for Sierra Leone with isolated, district-branded tenant, with role-based access matched to the Council's org chart — Chief Administrator, Head of Revenue, Finance Officers, Data Entry Clerks, Field Collectors, and external Auditors.
- • Web portal for office-based staff, finance, and audit.
- • Companion mobile app for door-to-door assessment, service, and collection.
- • Sovereign hosting — data stays under the Council's control.
- • Standards alignment — ISA, IFRS 15, GASB 33/34, IAAO, and the Local Government Act 2022.

What Made the Difference
The capabilities that mattered most
Five payment channels
Monime USSD, Monime Payment Code, bank deposit with slip verification, field-officer mobile app, and cash-to-bank — each with its own audit trail.
Bank reconciliation with slip proof
Taxpayers upload the deposit slip; Finance Officers verify against system totals before it reflects on the property.
Print-ready Auditor Report
Coverage, revenue by channel, aging, appeals, and reconciliation ledger — handed to the auditor in a single PDF on day one.

In the Field
Collection that reaches the ledger
Kambia's field officers work offline-first on the PaM mobile app — capturing signatures and GPS at the door, issuing on-device receipts, and syncing automatically when connectivity returns. Nothing is lost between the street and the audit log.
“PaMGIS has significantly strengthened Kambia District Council’s revenue administration by improving the identification, documentation, and tracking of revenue sources across the district. The GIS-based revenue data has given our revenue team better information for planning, monitoring, and follow-up, while helping the Council build a more transparent and reliable revenue base. We see PaMGIS as an important innovation in our continued efforts to improve internally generated revenue and modernize local revenue management.”
