Requesting Payment by Email Invoices What is it? Email invoicing lets you sell without an online store. Buyers can place orders from you by phone, fax, email or other offline means; then you send email invoices from the Merchant Center to the buyers requesting payment. Email invoices contain a personalized message from you regarding the requested payment as well as a "Pay now through Google Checkout" link. When buyers click this link, they are brought to Google Checkout where they can complete the payment process. Best for: Use this option if you don't have or need an online store. Time required: There's no setup — just open a Google Checkout merchant account and you can immediately start sending invoices. Technical skills required: None. Just Internet access.

Can you submit the form data in the way that the google checkout portal does? then it would authenticate and autofill the form?
