Billing after Credit Card payment
Hey guys! so I'm working on creating a website for a service where prices can fluctuate based on the information customers have entered. However if the information they enter is incorrect I want the ability to charge the credit card they entered extra fees which they will be warned about. So they will have to enter some kind of billing agreement. How do I go about doing this? Usually, with my previous ecommerce exp the customer just pays and then your done. Is there a service I can work with that will help facilitate this? I was thinking of using square online payments but I don't know if this is supported.
