Questionnaire for app subscription

Hi there,

We are currently looking into creating a new questionnaire for our company with Typeform however after a conversation with one of the sales team we are unsure if it is the right fit for us and have a few questions. We are a SaaS healthcare company with a subscription based app.

• Can you create additional fields on the contact form such as username when the customer is signing up?
• If we are creating a subscription based product do we need to host the stripe payment outside of the questionnaire as Typeform does not support subscriptions?
• When embedding a form in a webpage can you take away the Typeform branding in the loading and at the bottom of the page?

We’d love to know if Typeform would work for us. 

Thanks!
