Hi Product Hunt — I’m Arun, and I built InvoiceDrift after wondering why a simple question — did this supplier bill differ from what was agreed? — still takes so much manual checking. This is an early pilot, not a finished procurement platform. You upload one supplier invoice and one PO, quote or previous invoice. InvoiceDrift shows the evidence behind each difference. When descriptions are unclear, it does not force a match; you can resolve it, and it remembers that mapping privately for the business next time. Privacy mattered from the start: standard document processing happens in the browser. Optional AI sees only sanitized uncertain descriptions, not files or financial values. I’d genuinely value feedback from bookkeepers, office managers and small-business owners: where is the report useful, and where could it mislead you?
