Creating two distinct sign up forms using the user accounts package

I am building an eCommerce website. I want to have different sign up page for seller and the customer. I tried using the accounts package, but the atForm template does not allow more than one sign up form. Is there any way to add more than one sign up form using accounts package?

Customer Sign Up form shall contain:

  1. Mobile Number
  2. Password

Seller Sign Up form shall contain:

  1. Fullname
  2. Email Id
  3. Mobile Number
  4. Password
