How can I input a credit card option that's not tied to a vendor?

I want to input an option where someone can submit a payment using their credit card info but I don't want it to be associated with a specific vendor.  Is this possible?

Unfortunately, you cannot collect credit card information using JotForm if that is what you have in mind. You can still however just collect orders using Purchase order field, of which guide you can find here: https://www.jotform.com/help/460-How-to-Create-Payment-Form-with-Purchase-Order
