Is there a way to use the same submit button to submit an Infusionsoft form and a payment gateway form?

I am trying to make it simple as possible for our customers to submit their contact details as well as their payment details, so I have created a form in a campaign, and we have set up our payment gateway, but is it possible to submit both forms with the one button? So the payment is processed to the merchant service and the contact details are sent to Infusionsoft?

Be glad of feedback and help on how to acheive this!

Thanks in advance.
