MarginLeak reads the fine print in restaurant invoices

Field notes

The sample workspace separates price increases, pack-size changes, and possible duplicates, then lets the reviewer inspect the original invoice lines before marking a finding reviewed or dismissed. Its example data covers 12 invoices, three suppliers, and $16,378 in purchases, including a tomato case whose contents fall from 20 pounds to 16. The page also offers a $99 pilot for up to 20 invoices or 200 line items, but identifies the product as an MVP and reports no confirmed recovered money or credits.
