Downloading An Invoice
When making a purchase you will automatically be sent a receipt email by the payment provider (in the case of PayPal to your PayPal email address) containing the details of your payment. This is generally sufficient for tax and/or accounting purposes, however in some rare instances a company may require an invoice as well for their records.
A printable invoice can be downloaded for the purchase from the View Invoice page. You will need the receipt/transaction number and billing email address for the purchase to be able to view the invoice.
