How much money is hiding in your salon's booking system?
Every appointment business leaks money the same three ways: empty gaps that never fill, cancellations that never refill, and clients who quietly stop coming back. The interesting question isn't whether your diary leaks. It's how much yours is worth.
Three real diaries, three sizes
These are anonymised UK booking records from businesses connected to us, analysed appointment by appointment. Nothing modelled, nothing made up, and nothing presented as an independent customer result.
Part-time solo nail salon. 41 lapsed clients holding £2,340 of past spend, 15 regulars overdue a visit. Even on part-time hours, £680 realistically recoverable.
One shop, a few chairs. Around 650 clients had quietly stopped rebooking, which is a counted fact. The £8,898 is a model across three groups at assumed win-back rates, only £3,684 of it sits with those 650, and none of it has been recovered.
Four-shop barber group. Just under 3,000 lapsed clients across the group. The same leak as the solo salon, multiplied by every extra chair.
The pattern is identical at every size
The leak isn't a small-business problem or a big-business problem. It's a diary problem. Getting bigger just gives it more places to hide, and makes it less likely anyone is watching. The four-shop group wasn't being careless. There was simply no one whose job it was to notice 3,000 quiet goodbyes, one at a time.
Why nobody notices
Because the diary looks busy. A full week today hides a quiet month in autumn. Booking systems are brilliant at answering "what's on today" and mostly silent on "who didn't come back". So the leak never shows up as an event. It shows up as a slightly worse year.

Two ways, both free. The 30-second leak calculator gives you a rough figure from three questions. Or send six totals off your own booking dashboard and I will work out the real one. No client list, no export, and nothing goes near an AI.
