If you've already assigned the items or services on the customer's invoice to the job, there's no need to do anything. The job records were updated when you recorded the invoice.
If you didn't enter the job number on the invoice, you'll need to do so. Begin by displaying the transaction in the Sales window. You can do this by locating the transaction in the Sales Register window and double-clicking it.
The next steps you need to follow depend upon whether your transactions are changeable or unchangeable. (If you're unfamiliar with changeable and unchangeable transactions, or if you're unsure which option applies to you, please read What are changeable and unchangeable transactions before continuing.) If your transactions are changeable, simply make whatever changes are needed, then click Record.
If your transactions are unchangeable, choose Reverse Sale from the Edit menu. A transaction that undoes the effects of the original, incorrect transaction is displayed. Review it, make any necessary changes - you can change the invoice number, date, journal memo and Already Printed option if you like - and click the Record Reversal button. Then reenter the transaction with the necessary changes.
