[You can access the Billing History Screen by selecting 'My Account' then 'Billing History']
You can use this screen to keep a track of your payments to RepricerExpress and print out your invoices. Previous payment will be listed here and you can view an invoice by selecting the appropriate row and hitting the 'View' button. These invoices can then be printed off as you need them.
RepricerExpress will also email you each time a successful or failed payment attempt is made.
