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.

I am trying to do the same thing but the period that these POs are in was closed by the CPA that did the taxes. Is there a way to close or delete the open POs without the Password the CPA put in place to protect the prior year closing. 

Happy to see you here in the Community, nancy93! You can, in fact, edit or change the password so you can deal with those transactions. Here's how:

1. Sign in as admin. 
2. Click the Gear icon and select Account and settings.
3. From the Advanced tab, select the Accounting section.
4. Under the Closing date field, choose either to close the books with a warning only or with a password too.
5. To change the password, just enter a new password in the Password and Confirm Password fields.
6. Tap Save and Done.

That should do it! Please let me know if you experience any issues. I will be around, so don't hesitate to reach back out! See you later! 

Should i rather delete not used purchase orders or mark it as closed? What's the difference between the two?

Is there a way to mass delete only the open purchase orders that don't have some items received on it?

Several of my po have some items received but most have 0 so those need to be deleted.

Deciding whether to delete unused purchase orders (PO) or mark them as closed depends on your specific needs and how you prefer to manage your records, APnj.

Here's the difference between the two:

Deleting a purchase order removes it entirely from your records, and you'll have no reference to it later. On the other hand, marking it as closed keeps the PO in your records but shows that it's completed or inactive. This is helpful for reporting or historical tracking.

Concerning the mass delete option for purchase orders, there is no built-in feature to delete them in QuickBooks Online (QBO). You can delete them individually by opening each purchase order and selecting the "Delete" option.

While this isn't available, we would greatly appreciate it if you could share your valuable insights with our product development team. Your feedback can help us improve and create a better experience for you.

You can also consider using a third-party app or tool that integrates with QBO for bulk actions. Check out the QuickBooks App Store or visit the Apps menu within your QBO account.

What's more is to generate a report showing all payments made to vendors: Run a report with vendor totals. It helps you prioritize which vendors need to be paid and organize your accounts payable.
