What kind of payment options do you provide? All the managed Lemmy instances I've found so far seem to be credit card (or crypto) only, which would be a hassle for me. In The Netherlands, iDEAL is used for most online transactions, and can be easily set up through through Stripe for example.
Either way, this is a great development, kudos to you! :)
I'm more of a backender myself, but I think some UX mockup would go a long way in getting this improved.
