Yes – you can close a Purchase Order (PO) even if there are outstanding invoices against it, as long as you have the correct permissions.
Who Can Close a PO
Super Admin Users – have access by default and can close POs at any time.
Other Users – will need the correct permission enabled.
How to Enable Permission
If you are not a Super Admin but need to close POs, follow these steps (admin only):
Go to Settings > Roles and Permissions.
Edit the role you want to edit.
Scroll down to Purchases Permissions.
Enable the relevant permission for Closing Purchase Orders or Re-opening them.
Save your changes.
Once the permission is granted, the user will be able to close POs even if there are invoices outstanding.
Important Notes
Closing a PO does not automatically cancel or delete invoices – it simply prevents further items from being added to that PO.
Ensure all relevant financial entries are correct before closing to keep reporting accurate.
