Spent 3 weeks chasing a vendor invoice gap that turned out to be one missing PO number
Last month our main supplier in Ohio short paid us by $4,200 and I could not figure out why to save my life. I went back and forth with their AP rep for almost three weeks, pulled every packing slip, rechecked our price list twice, and even had our warehouse guy photograph the pallets. Turns out their system auto closed our account because one PO number was missing a digit, so every invoice after that got flagged and paid at a default rate. Fixed it in about ten minutes once we found it. Does anyone here have a real system for catching PO mismatches before they snowball, or is it just me eyeballing spreadsheets?
