Does it invoice fiat?
Credit/debit cards using Stripe, yes.
Hmm figuring it out. Connected stripe but not showing in invoice. Too bad no lightning option :(
It absolutely supports lightning. I don’t know if he’s on nostr, but the founder John is a great guy, and I’m sure he would be happy to talk you through it.
Oh I see options now
