Healthcare — Reference architecture · designed by Techmode

Clinic Appointment Booking on WhatsApp

WhatsApp appointment booking with real availability in the chat, automated reminders before the visit, digital intake forms and post-visit follow-up.

A reference architecture, not a client story. This describes a system we design and build — the problem it answers, how it is put together, and what it runs on. No client engagement stands behind this page, and we will not imply one.

It is a write-up, not something you can click. If you would rather use something than read about it, the Capability Lab has eleven demos you can open.

The problem

Where it goes wrong

Bookings can only be made by phone during working hours, so an evening caller either waits or goes elsewhere. Patients forget appointments nobody reminded them about, follow-up instructions given at the desk are gone by the time they matter, and an empty slot still costs the clinic its hour.

The solution

What we build

A WhatsApp booking flow where patients see real availability and book in-chat at any hour, with reminders sent ahead of the visit, intake forms completed before arrival, and follow-up messages after it. Slots are held against the clinic's own calendar, so the diary stays the single source of truth.

What changes

What the build delivers.

Appointments booked at any hour, in the chat, without a phone call

Reminders sent ahead of every visit without anyone remembering to send them

Intake completed before the patient arrives, so the consultation starts with the consultation

Design targets

What we build to.

Engineering targets for this build, not results measured for anyone. We have not shipped this for a client, so there is nothing to report.

Reminders scheduled 24 hours and 1 hour before the appointment

Availability read from the clinic calendar, so a slot cannot be double-booked
