Growing the business
The cheapest customer is the one who already came
You spent real money getting them through the door the first time. Getting them back costs a message — and almost nobody sends it.
Ask most owners where their next customer comes from and they will talk about advertising. Ask them how many people came once last year and never again, and the room goes quiet, because nobody has the number.
That number is almost always the biggest one in the business.
People do not leave. They drift
Very few customers decide to stop coming to you. They just do not get round to booking, and six weeks becomes six months, and by then coming back feels like a slightly awkward thing to do. Nothing went wrong. Nobody was unhappy. They simply fell out of the habit while you were busy.
Which means they are not lost. They are waiting to be reminded, and the reminder has to come from you, because it is not going to occur to them.
Noticing is the hard part
You cannot message the people who have drifted if you cannot see who they are. That is a list — everyone who came twice and has not been in ninety days — and it is the single most valuable list in the business. It is also the one almost nobody can produce, because it lives in a diary that only looks forwards.
Say something worth reading
A message that says "we miss you" is an advert. A message that says "it has been three months since your last treatment, here is your slot" is useful. The first gets ignored. The second gets booked, because it arrives at the moment the person was vaguely meaning to do something about it anyway.
The same is true the other way round. Someone who has just been in does not need a reminder; they need the appointment card, the aftercare, and to be left alone until it is time.
This is what trust is made of
Remembering what somebody had last time, how they like it, and when they are due is not a technique. It is the whole difference between a business people use and a business people belong to. It is also, unglamorously, a record that somebody kept.
What changes
A diary that fills from people you have already met, before you spend anything on finding new ones. The advertising still works — it just stops being the only thing holding the week up.
