Form Builders like Typeform, Formstack, Zoho Forms and Formsite do not charge
any commission from the payment you collect using different payment
integrations, though payment integrations are only available in selected
plans under these services. Other form builders like Wufoo and Jotform
also provide payment integrations but charge a fee of $0.30 per
transaction. Formstack is the only service that doesn’t charge any extra
fees for payment processors under all their plans.
