I'm here to help you today. Invoices for vendors are called bills in QuickBooks Online.
If you mean to delete the bill for a specific vendor, you'll simply need to remove the transaction. This way, you won't see the bill from the list. Let me show you how:
Go to Expenses from the left menu.
Locate the bill, then click the arrow under Action.
Choose Delete.
If you want to delete a vendor, make sure to delete all transaction from the profile. Otherwise, you won't be able to perform this action and just make it inactive in the system.
To delete a vendor :
From the left menu select Expenses then Vendors.
Select the vendor or customer's name.
Click Edit.
On Vendor information box, select Make inactive.
Once asked to confirm deactivation, select Yes.
