Open-Source Revenue Leakage Detector for Marketplaces and Ecommerce
Quick share in case it helps anyone running a marketplace (services / rentals / ecommerce). I built an open-source revenue leakage detector that continuously validates each transaction against your take-rate + pricing + discount rules — because Stripe (or any other provider) will happily “charge correctly”… even when the logic is wrong. It catches stuff like:
missing / zero commission (webhook or logic gaps)
sellers stuck on legacy take-rates
underpriced listings (min price not enforced)
discount abuse / expired codes still working
“free trial limbo” (usage continuing without payment)
