Question 1

Purchase order vs invoice — what is the difference?

Accepted Answer

A purchase order is the buyer committing to buy at agreed prices, sent before the work starts. An invoice is the seller requesting payment after the work is done. So no — a purchase order is not the same as an invoice: the PO starts the job, the invoice finishes it. Asking “what is a purchase order vs invoice?” usually means someone sent the wrong one — check the direction: orders flow buyer → supplier, invoices flow supplier → buyer.
