You can add and manage connected payment accounts via your Paperform Account Settings:
Note that you'll need to have a payment account set up with a supported payment provider in order to connect it to your Paperform account. So the first thing you need to have in place is registering an account with either Stripe, Braintree, PayPal Business, or Square.
Once connected to your account, payment accounts can then be added to select forms in the form editor so you can start collecting payments from your customers.
You might like to have a Stripe account and a PayPal business account connected to your Paperform account, or you may even have more. The number of payment accounts you can connect will depend on what plan you’re on:
Paperform Essentials Plan: 1 payment account
Paperform Pro Plan: up to 3 payment accounts
Paperform Agency Plan: unlimited payment accounts
