Why does the new generated invoice number in QBO are not in sequence?

Hello there, HYR. I recognize the importance of having a sequence order of your invoice number in QuickBooks.

The changes in the sequence on the invoice number happen when you manually enter digits. Since the QuickBooks numbering system automatically generates the number based on the old numeral entered on a form. 

To verify, I recommend checking the last invoice number used. We can utilize the magnifying glass to search the transactions you need. 

Here's how:

1. Click the Magnifying glass icon in the upper right-hand 
2. Select the Advanced Search link. 
3. Type either memo, amount, or reference number in the search field. 
4. Set the date of the invoice transaction you're looking for. 
5. Choose Apply.

From there, see the last invoice number and review why the sequence changes, then edit it to continue using the desired number.

Additionally, here are some links about personalizing your sales forms and recording invoice payments in QuickBooks:

• Customize invoices, estimates, and sales receipts
• Record invoice payments

I was informed by one of the QBO support members the problem was caused by a glitch in QBO system.  It has now been resolve.
