One of the bigger drawbacks of Adyen vs Stripe, although we wanted to work with them a lot, is, they require a crazy reserve (in the millions) if your model is subscription based. The logic behind it from them is, that they must be able to refund all your customers in case you go bankrupt, and you have subscribers left hanging without full-filled service they paid in advance for.

Although I get the logic behind it, not one other PSP requires such a huge reserve, therefore we decided not to work with them.

Todays payments world is v competitive and players like checkout.com and many others are v aggresive trying to disrupt stripe's dominance in this area
