Your accounts say you made a profit. They don't say that a whole slice of your sales lost money on the way — tiny orders that cost more to fulfil than they earn, a product that looks healthy at gross margin but bleeds once refunds, shipping, fees and support are counted, international cards that cost far more than domestic, a discount campaign that lifted revenue and cut contribution.

Money Leak Autopsy takes your real transactions — dropped in from Stripe, PayPal, Shopify, your bank, a marketplace export or a plain CSV — and computes the true contribution of every single one. Then it dissects where money systematically leaks, ranks each leak by the dollars it drains, and shows the segment you should stop wanting: the highest-revenue slice that is not your highest-value slice, with the exact mix-shift that adds profit without adding sales.

Your data is parsed and analysed entirely in your browser — the CSV never leaves your device. Every field is optional; the more real cost data you add, the more the numbers move from estimated to exact, and the report tells you honestly how complete the picture is.
