How the day fills
What happens while nobody is at the desk
Most gaps in a clinic diary open outside opening hours, when a patient cancels late at night or books first thing. Quellow deals with them as they happen.
A patient books the last 9:30 online.
Your booking page only offers real free slots, for the right clinician and the right appointment length. The booking lands in the diary and a confirmation text goes out.

A cancellation goes straight to the waitlist.
When a patient replies CANCEL to a reminder, Quellow offers the slot by text to the first person on the waitlist it suits. The first YES gets it.

Knee, first visit · Hana Okoye · 10:45
Two bookings land on the same time.
The later one moves to the nearest free slot with the same clinician, or another with the same role, and the patient is told by text.

The day closes with nothing left to chase.
Tomorrow’s reminders are queued, the waitlist is up to date, and reception gets a one-page note of what changed.

Confirms the visit. Nothing else happens.
CANCEL

MOVE
Sends back three other times with the same clinician.

By the time I unlock the front door, the 9:15 that cancelled overnight already has someone new in it.
