How to confirm the next invoice number to use?

If you want to confirm which last invoice number was used, you can access a transaction details report:

1. In the main screen of Sage 50, click on Reports, Transaction Details (or Journal Entries), Sales
2. In the report options window, select the proper date range that will include the latest transactions you have done
3. Click OK
4. Look for the latest/highest journal number, which would normally be towards the end of the report
• If you look to the right of the Journal Number along the first line under the heading "Account Number" that is your Invoice Number and the name of the client
5. Once you know which invoice number was last generated, you can follow the steps in Related Resources: "How to reset numbers for invoices and other forms?" to change the next invoice number to be used.
