Closing old purchase order but still show up when creating new purchase order

The details that showed up when creating a new purchase order for your supplier are pre-filled information from your previous transaction, Mgrace08. Let me discuss this further.

In QuickBooks Online (QBO), there's a feature that automatically fills in the details of a transaction (excluding the date) when you select a supplier, employee, or customer while entering bills, writing checks, or recording credit card credits. Even if your recent purchase order is closed, its information is available. If you'd like to turn off this feature, I'll guide you through the process by following the steps below:

1. Log into your QBO account.
2. Go to the Gear Icon, then select Account and Settings under Your Company.
3. Click on the Advance tab, then go to the Automation section.
4. Hit the pencil icon to configure.
5. Toggle the button next to pre-fill forms with previously entered content to the off position.
6. Once done, click Save.

Further information about this feature can be found in this article: Use auto-recall to pre-fill transactions in QuickBooks Online.

I'm also adding this article that outlines the procedures for adding an accepted purchase order to a vendor transaction: Add purchase orders to expenses, bills, or checks in QuickBooks Online.
