@Car you asked @k00b in the last SNL what solutions are available today for a small merchant (coffee stall) to being able to accept Bitcoin quickly, without any hassle.
So what I suggest is the following scenario.
keep it simple in the beginning, don't over-complicate things for a newbie. Let them discover step by step all the solutions available and that way they will learn more.
inform them about the differences between custodial and non-custodial solutions. Sometimes a custodial solution could be useful as a decoy for receiving payments (as I explained in this guide). Withdrawing periodically from a custodial account is strongly recommended. A non-custodial solution sometimes involve more knowledge and capital allocation.
depending on each merchant business profile, recommend the more suitable solution for them, not for your taste. Your usual BTC/LN wallet maybe is not the perfect way for a merchant, so try to put yourself in their situation and how they operate.
Here I would list some solutions that can be used (I tested myself):
Blink Wallet - custodial, LN address, PoS webpage (very good for employees), merchants map, circles, easy to use, open source developed by Galoy team.
LifPay - custodial, LN address, Lightning page, easy to use, no KYC
LightningTipBot - custodial Telegram LN bot used with Zeus or Bluewallet app, LNURL, LN address, many other features
Alby - custodial browser extension, LNURL, LN address, can be imported into Zeus and Bluewallet app and used as a regular LN wallet.
Phoenix / Breez / Electrum mobile wallet - non-custodial, opening channels fees involved, swaps out are needed to empty the inbound channels and be ready for the next day.
Blixt / Zeus / Mutiny - non-custodial, full mobile LN node (neutrino), LN address, channels management, LSP, swaps out are needed to empty the inbound channels and be ready for the next day.
Nodeless - semi-custodial, auto-widrawals to your own wallets / LN address, full set of features for merchants with seamless integration into webshops, solution based on BTCPay server.
Use an "uncle Jim" Lightning Bank, as I explained in this guide - we need more skilled node runners to play the role of a "uncle Jim" LN bank for their local community and offer these semi-trusted solutions.
Bitcoinize - nice PoS machines, connected to many funding sources, NFC enabled, printing receipts.
I hope this quick guide will help you with your local small merchant friend.
