Invoice Date

Hi there, 

Thanks for taking the time to post in our Community. I'll be happy to steer you in the right direction. 

QuickBooks Online allows you enter any date you'd like when creating an invoice. Once the payment has been received you can always go back and change the invoice date. Here are the steps which show you how to change the invoice date:

1.     Go to Sales.
2.     In the Customers tab, click on the customer name.
3.     Select the invoice to open it up.
4.     Update the invoice date (due date).
5.     Click on Save and close.                                                        

Try these steps and let me know how you make out. I'd love to see you come back here with any questions. I'll be here to help.
