Credit card payment request with Paynova

We would like to offer the clients of our company the possibility to pay their invoices by credit card through using the credit card processing service of Paynova. What we would like to have developed is: Start page: A page where our company can enter the email address of a client, invoice amount and invoice number(s) as well as a text area to write the accompanying e-mail payment invitation. Template texts can be chosen. Once pressing submit this will generate an e-mail to the client requesting payment for the specified invoices and amount. This email will include a link for the receiving party to a page to process the payment. Payment information page: This page is opened by pressing the link. It will ask for all necessary credit card details as needed by Paynova. The total amount will be filled in automatically as well as the invoice number(s) and email address. Payment processing: Once pressing submit the payment will processed by communicating with Paynova and feedback of the result will be given on screen as well as per e-mail to the client and our office. A document describing the requirements of Paynova is included.
