Also, set the expectations right. He might not make any sales with btc at all. Also a possibility. So, it should take minimal effort to get started.
Very much right.
In my local area there is a regular Bitcoin meetup. So, any time we set up a new business with their own POS, next thing is to let all the community know and kindly ask them to consider spending a few sats there if they are interested in the kind of stuff the business sells. We also tell the business owner about nearby locations that accept Bitcoin so they can go and spend their earnings if they want.
