Hi When I create a new invoice the invoice number populates out of sequence and contains "-REV" following the number. This is Quickbooks online, not desktop version

Hi there,

It's essential you're able to work with correct number sequence on your account. QuickBooks is a powerful program that helps you streamline your work and I'll be happy to help you navigate it so you can reap the amazing benefits offered in QuickBooks. 

Based on what you've shared, it's important to note that QuickBooks automatically places transaction numbers on your transactions. This can be prevented by utilizing the Custom Transaction number feature in QuickBooks. The option allows you to assign one number and the rest of the sequence follows in order.

You can enable/disable the feature in the Account and Settings page. Here’s how:

1.    Go to the Gear icon and select Account and Settings.
2.    Choose Sales in the left navigation pane.
3.    Pick the pencil icon in the Sales form content section.
4.    Check the box next to Custom transaction numbers.
5.    Hit Save and then Done.

Let me know if this info helps. I'll be a message away in case you have other questions.
