While printing Invoice I need to get the sequence number on it

Welcome to the Community, @rrgloballeather-.

Let me help you get the sequence number while printing your invoice in QuickBooks Online (QBO).

Firstly, we'll have to turn off the Custom Transaction Numbers feature. This way, it will turn off the invoice number and when you're trying to print your invoices, the sequence number will be displayed.

Here's how:

1. Go to the Gear Icon.
2. Select Account and Settings, and go to the Sales tab.
3. Click the Pencil icon in the Sales form content row.
4. Turn off the Custom transaction numbers.
5. Click Save, then Done.

I'll also add this article to guide you in receiving and recording invoice payments: Record invoice payments in QBO.

I'll always be here, ready to back you up. If you have further questions about getting the sequence number while printing invoices or other QBO-related concerns. Please let us know any time in the thread. Keep safe!
