Hello there, AG6780.

You have the option to change the date of the invoice. But, the terms of the invoice will follow the date when the invoice is created. 

Here's how:

1. Go to Sales and select Customers.
2. Choose the name of the customer.
3. Select the invoice and update the Invoice date and service date.
4. Click on Save and close.

Here are articles you can read for additional reference:

• How to adjust invoice payment terms in QBO.
• Due date and invoice date do not match when using due on receipt term.

Let me know if there's anything else I can help you with. I'll be around to assist.
