Hi JMc2
AccountRight doesn't naturally have the ability to copy a sale. If that is required, the recommendation would be to use the recurring transaction feature as outlined on Changing the customer on a recorded invoice. If you did not want to use the recurring transaction in the future you would be looking at deleting it after that process - List>>Recurring Transactions>>Highlight the transaction and selecting Delete.
In saying that, the AccountRight browser interface actually does have the ability to duplicate a quote using the Save and duplicate option.
