I'm comparing the 4 services above, but don't yet have an Authorize.net account. Would it be better to get an Authorize.net account first?<p>The end goal is to move off of PayPal to manage our subscription billing.<p>Can someone explain exactly what I need? It seems like at least Authorize.net, one of the services above, and maybe also a merchant bank account. Thanks!
Ask HN: Do BillingCircle, Spreedly, Chargify, Cheddargetter need Authorize.net?
