Salesforce integration & saving credit card details with Stripe

We have a client with two problems they'd like to solve with an electronic form:

1. Digitise an existing paper form, and store the results in Salesforce as either a PDF attached to a contact object, or store the field values in a custom object linked to a contact object. We can pass the contact id in the URL when used to submit the form. 

2. Capture credit card charge authorisation, and store the submitted credit card details in Stripe (or another similar CC processor) as a customer which can be charged later. The form will need to have some parameters passed through in the URL. 

Is your product able to integrate with Salesforce, Stripe and/or Docusign? Which plan would be suitable for the above? 

1) You can integrate our forms with Salesforce, here is how: https://www.jotform.com/blog/salesforce-integration/

2) Here is how you can do it with Stripe: https://www.jotform.com/help/347-How-to-Capture-Stripe-Payment-Authorization

And you can add Docu Sign widget from the widgets section:

Regarding all the above, you don't have to be on a plan, all are available with our Free plan as well, but you're limited with how many submissions, payments you can collect, please check our pricing page: https://www.jotform.com/pricing

Thank you!
