Can I create a Salesforce form with payment integration via iCredit or Tranzila

Salesforce integration + Payment integration ?
 - Sure you can.

FormTitan provides a Salesforce integration that enables you to read and write from SF objects in real-time. It also enables you to collect payment through the form with Payment integration, via many payment processors, iCredit or Tranzila  amongst them. These 2 powerful features can co-exist, and work together inside your form. So...Yes - you can definitely create a form that is integrated with salesforce and also has payment integration. In fact, you can have them work together:
- by having your payment data pushed to SF along with the other pushed data. 
- by having data  pushed only after the payment was executed.
