Asking a company to upload sensitive billing data is a pretty big jump, especially if they're not sure if they even have a leakage problem.
So I made a zero-data calculator that asks a few questions about your pricing, contracts, discounts, billing model, etc. and gives you a rough guesstimate of potential leakage.
It's definitely not perfect, but I thought it could be a useful way to get an idea of your situation before handing over any data.
I'd love feedback on the questionnaire or anything else.
