The Challenge

Fragmented Spreadsheets & Rural Field Blindspots

Microfinance credit institutions in Zimbabwe manage thousands of client loans across urban centers and rural peri-urban markets. Operating with manual paper agreements and disconnected Excel sheets introduced severe bottlenecks:

  • ✕Reconciliation Lag: Collections taken by field loan officers took 3–5 days to post into central accounts.
  • ✕Offline Failure: Traditional web software broke down when loan officers entered low-connectivity 3G/Edge regions.
  • ✕Arrears Blindness: Management lacked real-time visibility into Portfolio-at-Risk (PAR) aging buckets (1–30, 31–60, 61–90+ days).
The AVS Solution

Decoupled Architecture with Offline-First Mobile Sync

AVS engineered a complete full-stack platform providing web administrative oversight paired with native mobile mobility for field agents:

  • ✓Offline Storage Queue: React Native app caches repayment records in hardware-encrypted local storage and syncs automatically upon reconnect.
  • ✓Automated Amortization: Pure Python loan calculator supporting Flat, Reducing Balance (EMI), and Compound interest models with IRR calculations.
  • ✓Double-Entry Ledger Sync: Every loan disbursement, payment, and penalty write-off automatically posts to the integrated General Ledger.
