Yes, Praxis is a platform that is connected to more then a hundred different psp's and the platform is already integrated with all of them (so you as a client need to
integrate with the praxis platform instead of each one), also the Praxis backoffice allows you to direct specific GEO's to specific PSP's for higher success rate.
But just to clarify, praxis saves you the integration process but you still have to onboard with each PSP and present the proper documents.
Yes the cost is minimum 2,500$ per month, thst is if︀ you didnt reach the minimum rate multiplied by volume - for example 5% rate, 0.05X50000︁ = 2500$.
I am not sure about the rate, but it is lower, yet if︂ you dont reach the 2,500$ by processing then you are charged for the minimum anyways.︃
Not a cheap solution, but a great one. Especially for high risk merchants.
