while you are talking about SEPA, i know that there is a support for SEPA Direct Debit, but are you thinking about implementing Swiss Direct Debit, right now there are two sub implementation one from Postfinance and one from the Banks, there are talks about combining it in one system in 2 years or so but right now its kinda shitty + i would rather work with stipe api then with camt and pain files.
On the UI side, mind shooting me an email at [email protected]? I can share some stuff we're working on!
