What do you mean by the number of payments allowed for the different account types?

With JotForm you can receive payments through our different payment gateway integrations as explained on this link: https://www.jotform.com/help/chapter-7-Payment+Forms 

The limit refers to the number of payments you receive through your forms, so someone may purchase multiple products in one single submission and that will count as a payment, basically one submission with a payment attached (no matter the purchased products, amount, payment type) counts as one payment and it uses the payments limit.

If you have more questions, let us know.
