I'm working on an ruby on rails app that has a special billing method.
I'm creating a store where users can reserve products but will not get charged for these products until a certain amount has been reached. This amount cannot be quantified by time so I'm wondering if this is a recurring payment. However, accounts will have to provide a payment method in order to reserve these products and it is cumbersome to have them give their information every time. What's more is that I need their information so I know they want the product but I won't charge it right away.
What to do?
