Payment Processor Recommendations for SaaS / API Service I am starting a site that charges customers for the use of an API, Web UI Components, and some other things. There is a monthly base price, and then there is monthly usage fees. Is there a payment provider out there that: * Is easy to setup * doesn't require merchant accounts * handles recurring billing AND usage billing * only charges a fee on transactions, not an additional monthly fee? Also, is there anything I should watch out for when evaluating the (hundreds?) of payment processors out there? Some sites I've looked at so far (though, by no means do I prefer any of these): Stripe, FatMerchant, Chargebee. I've been a user of Freshbooks for years with my software consulting business. Does anyone just use Freshbooks for SaaS billing? |
