You probably know all of this, but if not… @Zaprite allows you to invoice, but additionally someone can pay in fiat and you can stack on the backend. I don’t know @Colorado Craig personally but he has a very cool nonprofit and he’s using it for donations. It looks/feels just like any other payment interface for a nonprofit. On Shopify you can use @npub1nvqd...kefq . I’m using that as an option for people to buy my book. They take a percentage but that’s fine - and still less than the he credit card fee. If you’re more technically inclined and have bigger volumes @BTCPay Server may be the way to go.

Yes, Zaprite services work great for the All-State Game. I also have a nonprofit account through Strike.
