Thank you for posting here in the Community, @CDub1.
I'm here to share information about a recurring invoice with repeating numbers.
The number sequence of the recurring invoices should not repeat old numbers unless someone changes it and start with the original number. The incoming invoices will follow the newly set number.
You can check the Audit Log for changes made to the invoice number.
Here's how:
- From the QuickBooks Online (QBO) dashboard, go to the Gear icon.
- Tap on Audit Log under Tools.
- Select Date Changed from the Gear icon beside Print.
If you don't have this option, make sure to open QuickBooks as a master administrator. You may also perform the basic browser troubleshooting steps to isolate the issue.
I suggest you create a new template or edit the last invoice with the number you want to use. Rest assured, next invoice will follow the sequence.
You can check this article to learn more about the process: Add custom transaction numbers to sales forms in QuickBooks Online.
I'm also adding this guide to run transaction list reports so you can check the details for all invoices: Run reports in QuickBooks Online.
Let me know if you have additional questions about recurring invoices in QuickBooks Online. I'm always here to help. Have a great day.
