How to change the invoice # sequence

Ok, I just figured out the solution. I was creating a new invoice by *copying* the invoice that I had changed and hoping QB would auto # the new invoice created from the copy with the higher # but it kept reverting to the old #s. When I tried creating a brand new invoice - rather than making a copy of the existing one with the invoice # I had to manually change - it worked. QB auto-generated an invoice # that was 1 higher than the last # (1623) that i manually entered. I hope this helps someone having this issue!

My problem is that the number keeps reverting to an old sequence pluse next letter in the alphabet and I am not copying the invoice. This happens dispite my making a manual change on the previous invoice.

Hello there, ron-baer.

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.

The invoice numbers in QuickBooks are typically assigned automatically based on the existing sequence. However, you can work around this limitation by following these steps:

Void or Delete Existing Invoices (Caution):

Voiding an invoice keeps a record of it but marks it as "voided," so it won't affect your financials.
Deleting an invoice removes it entirely, including from the records.
Adjust Invoice Numbers:

After voiding or deleting the invoices, you can create new ones with the desired invoice numbers. QuickBooks usually assigns the next available number in the sequence, but by voiding or deleting, you can "skip" numbers.
Customize Invoice Number Manually:

In your new invoices, you can manually input the desired invoice number. Keep in mind that this may require more effort on your part to ensure that you don't duplicate numbers or create confusion.
Set the Custom Invoice Number as Default:

You can set the custom invoice number as the default for future transactions. This can be done by going to the "Custom Form Styles" and editing the invoice template.
Contact QuickBooks Support:

If you are unable to achieve your desired result through the above steps, it's recommended to contact QuickBooks support for guidance. They may provide additional insights or potential workarounds.
