php - Modify Subscriptions using PayPal vs Amazon FPS -

-

i have been looking @ setting web applications rely heavily on ability users , substantially modify subscriptions. may using marketplace features well, , need system supports both seamlessly.

i have seen multiple horror stories complexity of modifying subscriptions, including double billing, or cutting users off @ wrong time.

i sincerely hope, instance, article http://talklikeaduck.denhaven2.com/2007/09/02/how-to-cure-the-paypal-subscription-blues

is out of date. use cases have in mind more complex ones mentioned. sampling of do:

  • support multiple subscriptions , subscription types/levels. instance 1 user might have 1 plan billed monthly @ $10 , 10 plan c billed @ $50 per month , 1 plan d billed @ $100 per year.
  • support changing of arbitrary payment amounts. instance, user on $40 per month plan, changes $100 per month plan. cancels, signs again @ $50 per month before $100 period up. user should still $100 of service month paid $100 for, , should change $40 per month plan.
  • allow payments of subscription amounts between users. 1 user might initiate payment of 50% of whatever amount has paid system far. application handling these types of marketplace style operations , these payments should work in context of subscriptions...

it not appear there open source php library need either amazon or paypal. looking forward coding myself. (be glad proved wrong here, perhaps freemium php?). cannot use various subscription services available. because not support features above, , because need have direct access paypal or amazon fps api later cleverness via marketplace issues.

which brings me question. payment platform should choose ease of managing subscriptions? please send me in right direction, have time. not have time make wrong decision. please provide evidence preferences, , if possible detail work comparing 2 systems. google has other payment platform , subscription system in beta.. if propose other better system, please provider tons of reasons, because need popular payment engine people feel comfortable with!

i see asked question in december... if haven't found answer yet, have suggestions based on experience business problem identical yours.

which paypal api thinking of using? in using payflow xml api, found thousands of times easier roll own subscription service. if api you're using supports creating 'reference transactions' based on previous successful transaction id, may save headache keeping track of users' subscription amounts, keeping track of what's been paid, , creating billing script runs on daily cronjob, checking each user see if need pay (and how much), , creating reference sale each of them.

of course, don't forget have explicitly ask users' permission before start billing them on recurring basis, , there should recurring billing , privacy policy. 1 trouble setup pretty need create own scripts manage people's subscriptions , payments -- fortunately, tacking paypal recurring billing onto web app had subscriptions , accounting built-in.

let me know if need suggestions on how go this!
