I would go for self custodial Lightning wallets. Breez, Phoenix, Aqua (haven't tried myself) etc. Any others #AskNostr

I figured the concept of lightning channel liquidity would be WAY too much for a newcomer who is just trying to sell their products.
I planned on introducing that as a second phase, with me managing the liquidity. and then eventually offload that to them entirely.
also figured that having an exchange right at hand (Strike, CashApp, etc) would also be good for a newbie who might want to immediately convert incoming sats to dollars (against my judgement lol)
I would set them up with decent inbound liquidity at the beginning and explain only later if it ever becomes an issue. Remember, they will likely not have that many customers at the start who pay with this. About the question of exchanging to fiat, I would again help only once that becomes a need for them. My general strategy is to hook them up at the start with a basic solution, and solve obstacles later.
I have guided small number people (not merchants) in the past with either onchain or lightning, and I never regreted going the self custodial way (what I see as the correct way).
What I found surprisingly easy was explaining backup seeds. Since it is a physical thing (piece of paper), people alredy have an intuition for how to work with it. Explaining this part well is imo important. Put emphasis on "Do not loose it or you will loose your money! It is a secret!"
Phoenix does backup seed and also it has the splicing function, which is their way to enable for onchain and lightning with a single app. Imo the best for noobs. Disadvantage is high fees.
I'm not confident that you are properly simulating the mindset of the uninitiated.
"here's this thing, it's really great [a bunch of stuff they've never heard of and don't understand] and all you have to do is park a whole bunch of money in it in order to receive payments!" followed by "Ohh yea... that payment failed because your inbound liquidity is too low - just park more money in it!"
this sounds insane compared to "install Cash app, show a QR code"
Is your guy unwilling to learn anything new? He already showed some interest.
to be clear, I haven't even spoken to the store yet. they are about to open and I really want to pay them in bitcoin. I don't know ANYTHING about them.
maybe they're already bitcoiners!
I see. There is also the possibility that they will look at you weird once you bring BitCoins 🤪. Fingers crossed!
