i have no experience in this area and i am facing a gazillion of options that i, for sure, can't check all myself in detail. So i need your help, or better recommendations, to narrow the search a bit.
We need to offer in our commercial x-ray app a new kind of a purchase plan. A "volume plan" for a specified amount of images exposured. That means the customer should can do an in-app purchase to purchase another 1000, 2000, ... images for which he has to pay x, y, or z $$$.
Then he can exposure and process that amount of images and if the amount he paid for is running dry, he have to purchase another "amount package" and so on.
For this to accomplish, we need a kind of a payment service provider, that accepts all major credit card brands and also handles things that are important for business customers correctly (e.g. correct VAT following the customers country laws and a correct PDF invoice blah blah). That service should be at least available to customers in whole europe, even better if it is working worldwide (but not a prerequisite for the time i write this beg).
The purchase should be possible via an in-app purchase without needing the customer to open the browser and visit the service providers webpage (if this is possible - if not we have to accept of opening a browser, but the former is preferred). So a kind of web api for the service would be great. As we are developing the x-ray app in full ourselves, we can develop a module that can contact webpages, interpret the results sent by the services webserver and whatnot. The process just should be a stable and reliable for mostly unattended processing. If the purchase is complete and verified by the service provider, we need to get a notice from the provider in any way that we can process this in our house mostly automatically too (e.g. sending the customer a new license file, creating an invoice for the customer, blah blah).
Last thing to watch out for is of course the price (the fees) that the service provider will bill for his efforts. Okay, if he offers a better and seamless api/service then a higher fee is acceptable of course. But still, as lower as best.
So i kindly ask for recommendations what service providers i maybe shall check. Anyone here have experiences with billing providers on the web with his online-shop or whatnot and can share a recommendation or his experience? If i don't ask for too much, maybe one or two short lines which services, from my above mentioned points, i can expect from them, would be really a premium, superawesome, hypermega recommendation.
Out of the head comes to mind DigitalRiver and Paypal which i will first check now while i'm patiently waiting for the results of my most loved and useful think tank in the universe (the Doco forum
). But every other hint is also very much appreciated.
So let the recommendations coming!
Greetings, your grateful
