I can also vouch for coinpayments. I have used them to pay for things and it works very well. https://www.coinpayments.net
Now you just need to calculate the fees involved in accepting crypto payments.

Another option is to buy a script online that generates your wallet addresses for the payments along with a QR code to scan. Then you won't pay fees. I also suggest you move your coins to a cold wallet once a week at least.
They accept multiple currencies which is always nice.
