Almost every salon has a waiting list somewhere: a sticky note by the till, a note on the phone, the memory of whoever is on the desk. And almost none of them use it, for a very simple reason: when somebody cancels their eleven o'clock at nine in the morning, nobody has ten minutes to call four clients while doing a blow-dry.
A smart waiting list is one that makes those calls for you: to the right person, at the right moment, without bothering anybody else.
What a cancellation nobody fills really costs
An appointment cancelled two hours ahead isn't the problem of whoever cancels: they let you know. The problem is that the slot stays empty while somebody else wanted it. A colour, a cut or highlights that don't happen that day, with the stylist free and the chair empty.
How people get on the list
A waiting list works if joining it is as easy as booking. When somebody asks for Saturday morning and there's nothing left, instead of sending them off with «we'll let you know», ClaudIA offers the first free time and, if that doesn't suit, adds them to the list in the same conversation:
- Writing or calling. On WhatsApp, on Instagram or over the phone: ClaudIA adds people on every channel.
- With what they actually want. The service, the day, the stylist if they asked for one and the time that suited them.
- Only when it's needed. Before offering the list, ClaudIA checks the diary again: nobody ends up on a list with a free time in front of them.
- And from your dashboard, if somebody asks you at the desk.
What happens when a time frees up
A time frees up in lots of ways: somebody cancels on WhatsApp, you cancel from the diary, an appointment moves to another day, a whole series is cancelled. In every case ClaudIA does the same:
- It checks the time is still free in that stylist's diary. If somebody else has taken it in the meantime, nobody gets bothered.
- It picks one person only. Whoever asked for that service on that day, with that stylist if they asked for one, and who wanted a time close to the one that has freed up. Among equals, whoever has been waiting longest.
- It messages them on WhatsApp with the day, the time and the service, including when they joined by phone.
- If they say yes, it books the time in the same conversation, and their wait closes on its own. If they book the same service for another day by themselves, it closes too.
What makes it smart
| Situation | Waiting list on paper | ClaudIA's smart waiting list |
|---|---|---|
| The 11 o'clock cancels at 9 | Somebody has to remember and call | It offers itself there and then |
| Three people were waiting for that day | Everybody gets called, or the first one remembered | It goes to one: the best fit |
| They asked for their usual stylist | Depends on who is on the desk | They're only offered that stylist's slot |
| The person offered the slot doesn't reply | The slot stays empty | After five hours it moves to the next |
| A cancellation at three in the morning | — | It goes out at eight, if the time is still free |
| They've already got a slot elsewhere | They stay on the sticky note forever | Their wait closes on its own |
Two more details that make the difference day to day:
- Nobody gets the same offer twice. Whoever didn't reply goes back to their place on the list with their seniority intact, and ClaudIA remembers which time it offered them so it doesn't come back with the same one.
- The alert goes first. In WhatsApp's daily allowance of new conversations, waiting-list alerts take priority together with appointment reminders: even if you've sent a big campaign that day, the alert still goes out.
What you see on your dashboard
On the Home screen there's a card with how many people are waiting and a direct link to the list: who is waiting, what they asked for, who was offered which time and how long ago. It only asks you for a decision when there really is something to decide, for instance when somebody has been waiting for weeks and nothing that fits has come up: that's when a call from you is worth more than any message.
The waiting list, inside a diary that thinks
The waiting list is one piece of something bigger: a diary that tells the time a client takes up the chair apart from the time your hands are busy, that chains a cut and colour with no dead time and that sends the alert by itself when an appointment changes. The six tests we run in every demo, here.
And so there's less to fill, what prevents last-minute cancellations: the appointment reminder with enough notice, and being able to move the appointment by message instead of not turning up. The three together are what keep the diary full.
