I won't pretend to have a business that can accept bitcoin here but I imagine, adding bitcoin as a payment option is an additional benefit to my business that adds value with no drawback at all. It's quite simple to setup a bitcoin wallet and have a QR code ready for that rare customer who wants to pay in bitcoin.
I think the problem with companies using bitcoin is that they don't liquidate their bitcoin and are shocked by the volatility that they experience. If I accepted bitcoin as a payment method it think a good strategy would be to liquidate it immediately as if it were cash. I love bitcoin and will always hold but in a business that depends on non-bitcoin-payable operating expenses, I will have to do what is necessary.
