About Invoice folders
An invoice goes through various stages after you create it.
When you first create an invoice and e-mail it to your customer, it is placed automatically in the Unpaid folder.
If an invoice has not been paid by the due date, it moves automatically to the Overdue folder.
When a customer pays the invoice, it moves automatically to the Paid folder.
Delete an invoice
If you want to delete an invoice, click the folder that contains it, and then click Move to Trash. To restore an invoice from the Trash folder, click the Move back to link. The link will contain the name of the folder from which you originally deleted it (Move Back to Unpaid, Move Back to Overdue, or Move Back to Paid).
To delete an invoice from the Trash folder or the Drafts folder forever, click Delete Permanently.
Make a copy of an invoice
You can make a copy of an invoice. This is useful if you want to create a new invoice based on an existing invoice. When you click Make a copy, the copy of the invoice opens, ready to be edited.
