If you need to change the customer on a recorded invoice, here's the fastest way to do it:
Find and open the transaction to be modified and save it as a recurring transaction.
Delete the original transaction.
Go to Lists > Recurring Transactions, select the recurring transaction you just created and click Use Recurring. A new sale or purchase transaction is displayed.
Select the correct card for the transaction and ensure all other details are correct.
Click Record.
Go to Lists > Recurring Transactions, select the recurring transaction then click Delete.
