We run a BB in Le Lindois, and started to trade in June this year. Everyone has to pay a deposit, or the full amount up front, pending how far away the booking. Extras are written down and a bill is given at breakfast on the last day. too date..... so far not had anyone not pay, have had people not turn up but as they have paid a deposit its not too bad. As I am in the uk, it makes it a little easier, we accept paypal with a small charge or cheques, or if they are in europe they send their money direct to the B&B....... so hopefully we try and cover all angles
