- Open Purchase Orders and create one. Pick the vendor and the lines.
- Print or email it.
- When goods arrive, Receive. Enter what actually came. The rest of the order stays open.
- Stock increases by the received quantity. The vendor balance increases by what you now owe.
- Print barcode labels for the received lines.
- If Weighted Average is on, the product cost updates from this receive. If costing is Fixed / Manual, the cost stays until you edit the product. See Currency and product cost.

Paying the vendor is a payment on the vendor, not a second receive. See Vendors.
Next: Purchase returns.
