What Finance Teams Are Saying
Trusted by lecturers and students across Sri Lankan universities
"We were debating between a flat fine and a daily interest model for late fees. This tool showed us that flat rate collected more in the first 30 days, but compound overtook it by day 45. That single insight changed our policy completely."
"The grace period setting was essential for us — we give students a 14-day grace. Seeing exactly what the penalties look like from day 15 onwards on both models helped us set the daily rate at a level that was firm but not punitive."
"The crossover day highlighting is the most useful feature. We presented this to the finance committee showing that after week 6, compound was generating 40% more penalty revenue — that's the argument that got the policy changed."
"Simple and focused. We use it at the start of each semester to verify our penalty calculations are matching the policy documentation. Much faster than recreating the formula in Excel every time."
