This PO Check SOP provides a structured, accuracy driven workflow for matching inbound deliveries against Purchase Orders, ensuring correct quantities, product codes, pricing, and supplier compliance. It strengthens warehouse operations, logistics efficiency, inventory accuracy, and inbound receiving performance by preventing mismatches, unauthorised substitutions, and invoice disputes.
It supports warehouse optimisation through consistent verification, WMS receipting accuracy, and robust compliance documentation across goods in processes.
This SOP outlines the complete inbound PO checking process from vehicle arrival to PO closure, ensuring goods in teams verify every line item accurately and safely.
Includes:
Pre arrival PO preparation and WMS/ERP validation
Delivery note and supplier documentation checks
Line by line PO matching (product code, quantity, price, condition)
Handling shortages, overages, substitutions, and price mismatches
Discrepancy logging and driver sign off
WMS/ERP receipting and PO closure
Daily PO Check Log and discrepancy reporting
Integration with procurement and accounts payable workflows
