Small Business and BCH / Crpyto (Newbie here, First post, just got into BCH / Crypto)

Got a wallet on bitcoin.com and atomic wallet. Having fun with it.

Couple questions. I have a cousin in the USA who has a small barbershop. I want him to be able to receive BCH for his barber services. We were talking about it and he was super excited, but then brought up the worry around accounting and taxes.

Is there a solution that helps small business owners with taxes and something like BCH for payment of services?

Also, what tech or wallet recommendations would be best for a local small business like that?

Thanks!
