Receiving is where paperwork meets physical reality. The purchase order says 500 brackets; the truck contains whatever it contains. The goods receipt records what actually arrived, in what condition, on what date, and everything downstream inherits the quality of that record: inventory accuracy, supplier delivery statistics, accruals, and payment. Mechanically, the receiver scans the advanced shipping notice or pulls up the PO, counts, flags shortages or damage, and posts. Posting does three jobs at once: it increments inventory, books the accrual so finance sees the liability before any invoice exists, and creates the receipt leg of the three-way match that lets invoice matching release payment.

Late or sloppy receipts cause damage out of proportion to the effort they save. Post Tuesday's delivery on Friday and the supplier's record shows a miss it did not earn. Receive against the packing slip instead of the PO and over-shipments slide into stock unchallenged. Skip the receipt and the invoice has nothing to match, so payment stalls and the supplier starts calling. Two rules keep the function honest: receive the day freight lands, and never receive without a PO line to receive against.
