There are several ways to locate and delete a bill in QuickBooks Online.
Delete the bill from the Bill window
You can delete a bill from the Bill window, to enable you to review the details of the transaction. There are multiple ways to access the bill in the Bill window — from the Expense Transactions list, the Accounts Payable register, or from a report.
To delete a bill:
Open the invoice to delete using one of these methods:
From the left menu, select Expenses, and select the appropriate bill from the Expense Transactions list.
In the Accounts Payable account register, locate and select the bill.
Select the bill from within a report.
In the Bill window, select More at the bottom of the screen, and select Delete from the pop-up menu.
When prompted, select Yes to confirm that you want to delete the bill.
The bill is deleted.
Delete the bill without opening it
You can access the bill from the Expenses page and delete it without opening the bill.
From the left menu, select Expenses.
On the Expenses tab, locate the invoice to delete.
In the Action column, select Delete from the drop-down menu.
