Hello, kevin179.

We were unable to retro the previous date. QuickBooks accrue when the original invoice date moving forward.  

I understand how the workflow you're looking for will benefit your company. We can submit a request for this feature through our Feedback board. These requests and suggestions are forwarded to the Product Development Team. I want to assure you that your input is valued and that each update our developer team creates is designed to benefit our customers' businesses. 

Here's how: 

1. Access your QuickBooks Online company.
2. In the upper-right corner, click the Gear icon.
3. Under the Profile column, select Feedback.
4. Enter a brief description of your product suggestion, and then click Next.
5. Type your email address.
6. Once done, click Send Message.  

Additionally, I recommend the following resource which contains information related to invoices:

• Automate invoice reminders in QuickBooks Online.
• Set up and send progress invoices in QuickBooks Online. 

Let me know if there's anything else you need to know about changing the date on the invoice. Have a great day!
