Another way to create an invoice is to copy/clone an existing invoice to create a new one with similar content. This is especially useful if the invoice you will be creating is going to be the same as a previously created one but with slight differences.
From the Invoices List, find the specific invoice to be cloned. Click on the 3-dot menu and select Copy.
You can also access the copy/clone feature with the invoice open. Go to the Actions button and select Copy from the drop-down.
The invoice copy will be added to the list, next to the original invoice. This will have a new invoice number and due date, based on the customer’s payment terms.
Open the invoice and edit as may be needed.
