Auto populate not working for invoice numbers

Hi singhajayvir,

Welcome!  QuickBooks Online provides the automation you need to create your sales forms effortlessly.  It's essential that the automated sequencing is functioning to ensure your records are aligned.  I'd be glad to assist!

Automatic transaction numbers is already activated by default.  However, let's start by making sure this feature hasn't been turned off.  Here's how;

1. Go to Settings ⚙ and select Account and settings

2. Open the Sales tab, then click anywhere within the Sales form content section

3. Turn on Custom transaction numbers

4. Hit Save, then Done.

If you need to 'reset' the sequence, simply enter the next invoice number manually when you create a new invoice.  This will reset the sequence moving forward.

Feel free to reach out again, should any other questions come to mind.  We would be happy to help!
