If you wish to accept bitcoin as a payment for your brick-and-mortar business, the first thing to do is get yourself a 'We Accept Bitcoin' sticker.
You can then display a QR code at the bar/counter so that customers can make a payment using their mobile.
There is no paper trail with bitcoin. You can accept bitcoin and treat it like cash.
Further details about accepting bitcoin for businesses can be found here.
