What is the difference between a PO and a non-PO invoice?
BeginnerAnswer
A PO invoice references a purchase order raised before the goods or services were ordered, so it can be matched automatically to the PO and goods receipt. A non-PO invoice has no prior purchase order (common for utilities, rent, or professional fees) and must be coded and routed for manual approval by the appropriate budget holder.
Real-world example Office rent arrives as a non-PO invoice routed to the facilities manager, while raw-material invoices are PO-based and auto-matched.
