Matching a bill to a purchase order means checking the invoice lines against what was ordered (and sometimes received) before you pay. What is purchase order?
Before you start
- Sage 300 Purchase Orders

The Sage 300 way
Where to find it: Purchase Orders > P/O Transactions > Invoice Entry
- Create the PO (Purchase Order Entry) and the receipt (Receipt Entry).
- Open P/O Transactions > Invoice Entry and type the vendor Invoice Number.
- Enter the Receipt Number, or choose From Multiple Receipts and pick the receipts.
- The invoice shows the receipt information. Edit cost or quantity where the vendor invoice differs, then post.
- Cost differences post to the payables clearing account.
