Why there's a skipped invoice number?

I'm delighted to have you here, @management-je2te.

I can share insights on why there are numbers skipped when creating an invoice in QuickBooks Online (QBO).

The abovementioned concern happens if invoices are deleted from your company file. Since QuickBooks will assign transaction numbers according to their order, it will also automatically set the following number regardless if the previous one is voided or deleted.

To check, you'll want to utilize your Audit log report to ensure there are changes made to your account. Here's how:

1. Go to Settings, and select Audit log.
2. Select the appropriate User, Date, and Events filters from the Filter drop-down menu.
3. Click Apply.
4. Locate the deleted transaction.
5. Click the View button under the History column.
6. Under the Event column, you'll find all the information you need for the transaction.

Moreover, you'll want to review the invoices and manually correct the order of the number from where it was inaccurately assigned to the latest. Once done, start creating another transaction with the proper ordering.

It is possible that a invoice number was already assigned to a deleted transaction. You can run the Audit Log report to check if that's what happened. Here's how:

1. Go to Gear icon in the upper-right hand corner, then select Audit Log.
2. Click Filter, then check the Transactions box.
3. Select Deleted/Voided Transactions for Show.
4. Click Apply.
5. Go to the Event column to see if the invoice number was already assigned to a delete invoice. 

You can manually assign the skipped transaction number in the next invoice that you'll be creating. Then, the program will automatically follow the sequence and will the assign the correct numbers in the succeeding transactions.
