When working with clients I do ask that you give me at least 24 hours’ notice if you are unable to attend your appointment. Insufficient notice denies someone else the opportunity of an appointment. I accept there will be exceptional circumstances when it is impossible to give this amount of notice and will always act sympathetically.
In addition I work with significant overheads, most of which the client will never see (e.g. research, preparation time, producing materials, accountancy fees, heating, lighting, phone bills). I also of course pay tax and national insurance and therefore only a modest profit is generated. Whilst I am happy to work in this way, if a session is missed and not paid for I still incur all of the aforementioned costs. I hope you would agree it would be unfair to bear the cost for missed sessions. Under such circumstances I would consider it reasonable to ask you to pay 50% of the agreed rate for the missed session. The ‘missed payment fee’ means any losses incurred are kept to a minimum.
