how do I know that that booking is going to get filled I on my brochure any 50% booking taken from the bride to secure that date coz lets be honest if your as busy as you say you are then you would need to secure their booking wouldn't you in order to avoid dissapointment.
I think I know what your asking, it's hard to understand though.
I sometimes take a deposit if it is a client I have never seen before. But that would be refunded if they cancelled with 24 hours notice. Because, yes, as already stated, I would be able to fill the gap. If it were an all day booking, i would ask for a bit more notice, maybe a week, as i know if they cancelled with a week to go, the day would fill back up again.
I just don't see why your clients should suffer, because your not busy?! Now i don't mean for that to sound harsh, and yes, we are all running a business etc etc, but it is not their fault that you cant fill their slot back up with however many months notice. Sometimes in business you just have to cut your losses! Business is a risk.
You have a policy, and good on you for sticking to it. But maybe that is the reason you will struggle to fill the gap...? I for one wouldn't book an appointment knowing I was paying 50% wether i had the treatment or not.
