A 2-chair practice loses ≈ €3,000 a month to empty slots. Here's the model.
worked model
The short answer: about €3,000 a month at risk on a typical two-chair book, and roughly €1,800 of it recoverable
80 bookings a month at €150 a slot, with about a quarter of them booked far enough ahead to be at risk, is where that number comes from. It is a worked model rather than a client result, and every assumption in it is on this page. Lead time empties a chair, not forgetfulness: practitioner-reported curves run about 7% same-day to about 33% two weeks out. The three leaks below are the phone during treatment, that curve, and recall that never goes out.
Your appointment book says full. Your morning says otherwise. Two slots opened today because two people did not arrive. Nobody rang to explain.
This is an industry analysis, not a client result. Every number below comes from a published study or an open model, and it carries the label next to it.
Three leaks run through a typical two-chair practice. Empty chairs, calls that ring during treatment, recall that never goes out. Here is what each one costs.
The chair that nobody sat in
Start with the revenue you have already earned the right to. Eighty bookings a month at €150 average slot value is €12,000 of booked treatment (worked model).
Now apply the curve. No-show risk is not flat. It climbs with the gap between booking and appointment.
~7% · ~10% · >23% · ~33%
That is the whole insight, and it is checkable against your own diary. Booking latency drives no-shows more than reminder volume does. Long lead times are the risk, not forgetful patients.
Apply it to the €12,000. If recall and long-lead booking leave about 25% of those slots unattended, ≈ €3,000 a month walks away (worked model).
≈ €3,000 → ≈ €1,800
Pulling the effective rate toward ~10% is the realistic target, not zero. Tight slot latency, a reminder cadence matched to the lead time, and one-click reschedule get you there. That is ≈ €1,800 a month back (worked model), roughly 3 to 6× a typical care plan (worked model).
Your book has its own numbers. Put them in.
What do no-shows cost you?
≈ €1,800 a month walks away.
Estimate. Model: practitioner-reported no-show curves run 7% same-day to ~33% at two weeks out. Latency drives it, not reminders. Your real numbers replace it on the call.
The phone that rings during a treatment
Answering means interrupting paid work. Not answering means losing the next paid work. Reception cannot be at the desk, on the phone, and in the treatment room at once.
Callers stopped leaving messages years ago. They call the next practice on the list, and that practice books them.
This is not an experiment in German healthcare. It is already the norm at scale.
16,000 practices · ~3M calls a month
The machine answers in seconds, at 19:40 and on Sunday. It books into your calendar rules, or takes a structured message: name, number, reason, urgency. Urgent cases go straight to a human.
The recall that went out "sometime"
Your patient file is the cheapest appointment source you own. It is also the one nobody has time to work through.
5 to 25×
Recall is a list problem, not a marketing problem. Consent is already on file. The dates are already in the system. Nothing needs writing twice.
The machine works the list on schedule. Due patients get a respectful message at the right interval, with a slot they can take in one tap.
