Hi,How do I amend an overdue invoice please?Thanks for letting me know the steps to follow. It is quiite urgent.Many thanks!

You've come to the right place, @audreymanes.

You'll need to open the overdue invoice, then make some changes from there. Let me guide you how.

In your QuickBooks Online (QBO):

1. Go to the Sales menu.
2. Select the Invoices tab.
3. Locate and select the overdue invoice.
4. Then make some changes from there.
5. Once done, click Save or Save and send.

Then, in case you want to learn how to link a deposit to an invoice, I've got you this great article for reference: How to Link a Deposit to an Invoice.

Should you need further assistance with your QBO, don't hesitate to leave a comment below. I'm always here to help.
