I Built an App to Handle No-Shows and Late Cancellations

I Built an App to Handle No-Shows and Late Cancellations

If you run a dental practice, you already know this problem.

A patient cancels last minute. Or worse, they just do not show up.

The chair sits empty. The assistant is still paid. The doctor is still there. The overhead keeps running.

So we react the only way we know how.

We punish.

No-show fees. Late cancellation fees. Deposits. Warnings in bold red text.

And yet, the problem never really goes away.

After spending a lot of time inside dental workflows, front desks, and practice management systems, I realized something uncomfortable:

No-shows are not primarily a discipline problem.
They are a systems problem.

That realization is why I built ChairFill.


Why the Current Approach Fails

Most practices try to solve no-shows emotionally.

A patient wastes your time, so you charge them $50. It feels fair. It feels justified.

But let’s look at the math.

                
  •      $50 no-show fee collected
  •     
  •      One empty chair
  •     
  •      One unhappy patient
  •     
  •      Zero production   

Net result: +$50

Now compare that to a different outcome.

                
  •      Fee waived
  •     
  •      Chair filled with another patient
  •     
  •      $300 production
  •     
  •      Relationship preserved

Net result: +$300

Punishment feels good in the moment. Filling chairs wins long term.

The issue is not that practices do not want to fill last-minute openings.
It is that manual filling does not scale.

Calling down a waitlist takes time. Patients do not answer. Staff are already overwhelmed. By the time someone confirms, the slot is gone.

So the chair stays empty.


The Real Insight: Speed Beats Rules

The real enemy is not the patient.
It is time.

If a canceled slot is not filled within minutes, the probability drops fast.

So I stopped asking, “How do we enforce better behavior?”
And started asking, “How do we remove humans from the reaction loop?”

That question led to ChairFill.


What ChairFill Actually Does

ChairFill is not a messaging tool.
It is not a reminder system.

It is an autonomous scheduling agent.

It connects directly to the practice management system through NexHealth and monitors the schedule in real time.

When a slot is deleted, moved, or broken, ChairFill reacts instantly. No button clicks. No staff involvement.

From there, it does something most systems do not.


The Qualified Volume Engine

Most waitlist tools do one of two bad things.

They either blast the entire list, which feels spammy and reckless.

Or they cap outreach at an arbitrary number like 5 or 10, which leaves money on the table.

ChairFill does neither.

It reads actual clinical and scheduling data from the PMS and determines who is a true match based on:

                
  •      Procedure type
  •     
  •      Appointment length
  •     
  •      Provider preference
  •     
  •      Location

Then it texts everyone who qualifies.

If 3 patients match, 3 texts go out.
If 30 patients match, 30 texts go out.

No more. No less.

This maximizes fill probability without spamming irrelevant patients.

The general waitlist only activates if no true matches convert.


Preventing the “Everyone Texted Back Yes” Problem

One of the first objections people raise is valid:

“What happens if multiple patients say yes at the same time?”

This is where most systems quietly break.

ChairFill uses atomic locking, similar to how Ticketmaster handles high-demand seats.

Here is the sequence:

                
  1.      Patient A replies “YES”
  2.     
  3.      The system instantly locks the slot
  4.     
  5.      The appointment is written directly back into the PMS
  6.     
  7.      Patient B, who replies seconds later, receives a polite message saying the slot is already filled    

No double booking.
No staff scrambling.
No manual cleanup.

The front desk only sees the notification after the appointment is already booked.


The Results

Across early usage, the numbers have been consistent:

                
  •      Average fill time: under one minute
  •     
  •      Fill rate: around 87%
  •     
  •      Average monthly recovery: roughly $2,400    

Compare that to what most practices lose annually from cancellations and no-shows, which typically ranges from $20,000 to $70,000.

This is not new revenue.
It is recovered revenue.


What About Repeat Offenders?

Another common concern is fairness.

“What about patients who cancel over and over?”

ChairFill does not charge fees or require deposits for general patients. Barriers reduce bookings.

But the system does flag high-risk behavior.

After three or more cancellations, a patient is automatically marked and a Cancellation Protection Fee applies.

Important details:

                
  •      It is a prepayment, not a punishment
  •     
  •      If they attend, it applies 100% toward treatment
  •     
  •      If they cancel, it is forfeited

The framing matters.

“The system flagged your account.”

Not personal. Not emotional. Just policy.


The Philosophy Behind It All

The core idea is simple:

Stop punishing. Start filling.

Fees and deposits are prevention tools.
ChairFill is a cure.

Patients do not cancel because they are malicious.
They cancel because dentistry creates anxiety.

The dental chair feels like turbulence. You are strapped in, cannot talk, surrounded by noise and uncertainty.

Punishing fear damages trust.
Replacing fear with flexibility builds loyalty.


Why I Built This

I did not build ChairFill to argue about no-show fees.

I built it because empty chairs are a solvable problem.

Not with more rules.
Not with more staff effort.
But with better systems.

If cancellations are inevitable, then refilling must be automatic.

That is what ChairFill exists to do.


Let’s stop accepting the "inevitable" cancellation and start fixing the hole in the bucket.
