A copy of your invoices can be downloaded from Admin> My invoices (this is located in the ‘Mailing’ box on the admin page). 

Invoices are generated automatically by Docmail when a payment is made to your account. 

Clicking on the link will let you view the invoice as a PDF, which you can download or print. You will only see invoices for orders that have been paid for, or top-up’s you have made.
