Can you close out old Purchase Orders (from 2015) that werent linked to an invoice. I want to get rid of Purchase Orders that show as open, but aren't truly open anymore.

Great to have you here in the Community, @1txdoe. I’ll help you with closing purchase orders from prior years in QuickBooks Online (QBO).

Purchase orders are non-posting transactions, so moving them will have no effect on your financial reports. If they aren't received, you can either delete them from your record or immediately close the purchase orders.

1. Pull up your purchase orders first.
2. Select a transaction and click to open it.
3. Click the Open drop-down arrow next to the Vendor name.
4. Select Closed from the Purchase Order Status drop-down arrow.
5. Click Save and close.
