Nobody talks about what happens after the patient pays. 💊
It was a Tuesday morning in Mamfe. 📋 Stack of paper registers on my desk. A calculator. And a Regional audit three weeks away.
I needed to verify:
✅ Decade deposits — all correct?
✅ — properly calculated?
✅ Cost recovery funds — not overspent?
✅ Solidarity Fund — deposited at BISEC?
Four verification streams. All manual. All prone to error. In a district where the hospital had been a ruin just 18 months earlier. 🏥
That morning, I did what I always do when a problem has no good solution:
I built one. 🛠️
---
Today, I'm releasing that tool publicly — for free.
🔬 The Internally Generated Funds Financial Management Tool is a single HTML file that:
→ Automates the official 6-step formula in real time
→ Captures daily revenues across 12 service lines by service tab
→ Calculates Net RA per from actual daily revenues — not monthly total ÷ 3 (the most common manual error)
→ Runs a 6-point engine that cross-checks every financial data pair simultaneously
→ Generates print-ready audit reports for IGF, DRSP, and submission
→ Works with zero internet, zero installation, zero server — open the file, begin
It was built in Mamfe, tested in one of the most operationally complex health districts in Cameroon, and applied in a hospital that reopened after being burned during the sociopolitical crisis.
It is not an official product. It is something better: a tool built by someone who actually does the job, understands the regulations from the inside, and needed it to work in the field.
📖 The full story — why I built it, how the triangulation engine works, and what this means for in Francophone Africa — is on Digital Health Africa:
