      We do not offer shopping carts on 123FormBuilder, but we do offer the possibility to integrate merchant gateways such as to your online order forms. It’s quite simple: you create your order form (customize it as you want), you assign the prices and other payment settings, and integrate it with a payment gateway that we offer. You enter your merchant account information for the two apps to sync so that each submission will create a transaction in your account.
