Hi all

I am playing with using Phoenix with LiveView for a small SaaS app that is more for fun and self-educational purposes, but should still be able to have paid plans and.. I failed to figure any standard libraries and advices on how to handle it in Elixir.

Just integrating stripe payments with a library is relatively easy, any other payment provider will also provide you with some sort of a webhook, when payment is happening, but what do you do on the phoenix side then?

What do you use for defining payment plans, tracking credit expirations (which can be tricky with e.g. monthly ones, because of different number of days per month and with taking into account the payer time zone), promo code discounts, etc?

Do you always build all these things from scratch? Or somehow just tunnel the stripe or similar services data to user? Or are there some known libraries to handle some of these matters?
