Thank you for clarifying your concern, @kenneth-eaztglob.

It seems that you're trying to continue the number sequence when you migrate to another QuickBooks Online (QBO) account. In this case, you'll need to enter the following number sequence once after migrating. This way, QuickBooks will continue the number sequence automatically. To do so, let's first turn on the Custom transaction numbers feature. Here's how:

1. Sign in to your QBO account.
2. Click the Gear icon, then select Account and Settings.
3. Select Sales from the left menu.
4. Go to the Sales form content and turn on the Custom transaction number.
5. Click Save, then Done.

Then, by the time you create a new transaction in QBO, it will follow the last sequence number you used. Also, I've added these articles to learn more on how to change and customize your sales forms in QuickBooks:

Keep in touch if you need any more assistance with this, or there's something else I can do for you. I've got your back. Have a good day.
