In regard to the security deposit or guarantee, does each company require a deposit? I am thinking of a business, say, a 300 bed hotel. Do each of the companies require a deposit, including from existing and fully paid customers and, if so, how is that deposit calculated? Can supply be cut in the event of non-payment of a security deposit, although supply has been paid for? What happens to that deposit during a customer switch?
