Rebuilding patient booking for a growing clinic group

The challenge

Each clinic in the group had picked its own booking tool. Patients saw different flows depending on which clinic they chose, and reception staff copied appointments between systems by hand.

Many patients book on older phones and assistive technology, so accessibility and page weight mattered as much as features.

The approach

• Ran short sessions with reception staff at two clinics to learn how bookings really happen, including the phone calls.
• Built a server-rendered booking flow with progressive enhancement, so it works without JavaScript and on slow connections.
• Designed the availability model around clinicians rather than rooms, which removed most of the double-booking edge cases.
• Moved clinics over one at a time behind a feature flag, with end-to-end tests covering every appointment type.

The result

All nine clinics run on one system. Reception teams stopped re-keying appointments, and the booking flow passed an external accessibility audit before launch.

“Calm, clear and thorough. Our receptionists actually asked to keep the weekly demos going after launch.”
