A doctor can't make it. Every patient is already rebooked.

Archster Health runs your clinic's WhatsApp, appointments and availability. When a schedule breaks, it offers each patient a new time, and only asks you about the ones it couldn't fix.

The doctor is running late. What does your front desk do?

An example morning with ten affected patients. The numbers are illustrative.

Without Archster

  1. The doctor is held up. Ten booked patients are still on the way.

  2. The front desk starts phoning patients one by one.

  3. Lines are busy. Some patients are already in the waiting room.

  4. Missed calls pile up. Nobody is sure who was told.

  5. Patients are rebooked on paper. Someone has to enter it later.

With Archster

  1. You mark the doctor unavailable. Archster lists the ten affected patients.

  2. Each patient gets a short list of real open slots on WhatsApp.

  3. Replies book the new slots, each one checked again before it is confirmed.

  4. Six are rebooked, three are waiting for a reply, and one is on your Action required list.

What happens when a doctor can't make it

You mark the doctor unavailable. Archster does the phone calls. Times shown are an example morning.

  1. Archster finds who is affected

    Every booked patient the doctor can't see is listed. Nothing is moved or cancelled behind your back.

    Patients not seen 10
    • Meera Joshiwas 12:00
    • Rohan Kulkarniwas 12:15
    • Sunita Vermawas 12:30

  2. The doctor is asked about extra capacity

    If the day can stretch, the doctor approves a few extra patients. If nobody answers, the request expires after 30 minutes and the fallback starts.

    Extra capacity request

    Dr. Kane can see 3 more patients on Thursday?

An assistant that knows when to stop

The assistant answers routine questions and offers real slots. The moment a conversation needs a person, you take it over, and hand it back when you're done.

  • See every chat with the patient's details beside it
  • Take over or hand back with one switch
  • Booked, cancelled and rescheduled appointments appear in the chat

Try the switch on the right.

Hours that match the doctor's real day

Set the weekly hours once. When one date is different, add an exception. The weekly schedule stays exactly as it is.

  • Several working periods a day, with breaks
  • Day off, custom hours or a lower daily limit for one date
  • Slots are built from the schedule, so patients only see real times

Try it. This is a sample schedule.

Automation with a hand on the brake

A clinic can't have software making clinical or scheduling decisions on its own. Archster is built around that.

The assistant never books an appointment by itself.

It asks Archster's scheduling checks, which confirm the slot and the doctor's limit. If the slot is gone, the patient is told, not promised.

Patients are always told

If an appointment changes, the patient gets a message that says why and what to do next.

Approvals leave a record

Extra capacity needs a named approver, and every message sent to a patient is saved in the chat.

Access is set by role and doctor

Admins, doctors and front-desk staff each get only the screens and patients they need.

Your staff can step in any time

Switch the assistant off on any chat and reply yourself.

Questions clinics ask first

What if a patient doesn't reply?

They stay on your Action required list with the whole chat, so your staff can call them.

Does the assistant book appointments on its own?

No. It asks Archster's scheduling checks for real open slots, and a booking is confirmed only if the slot is still free. If it was taken, the patient is told and offered another time.

Will patients be moved without being asked?

No. Archster offers new times on WhatsApp and books one only after the patient replies. Nothing is moved or cancelled behind your back.

Can the doctor change one day only?

Yes. Add a leave day, different hours or a lower daily limit for that date. The weekly schedule stays as it is.

Can my staff reply instead of the assistant?

Yes. Take over any chat and the assistant stops. Switch it back on when you're finished.

Who can see patient information?

Each person sees what their role allows, and doctors see their own patients. Admins decide which roles get which screens.

Do patients need to install anything?

No. Patients keep using WhatsApp, the app they already have.

Do I need a WhatsApp Business number?

Yes. Archster connects to WhatsApp through Meta's WhatsApp Business platform, so the clinic needs a WhatsApp Business number. We walk you through connecting it.

Can I see how many bookings come from WhatsApp?

Yes. Reports show the share booked on WhatsApp, bookings by channel, status, doctor and month, and you can export them to CSV.

How much does it cost?

Pricing is in rupees and depends on your clinic. We share it on the demo call.

How long does setup take?

It depends on how many doctors you have and how their schedules work. We give you a clear plan on the demo call.

See it on your own clinic's day

We set up a sample schedule that looks like yours, then break it on purpose so you can watch the rebooking happen.

  • 20 minutes on a video call, no preparation needed
  • Your questions about WhatsApp, patients and doctors' schedules
  • Pricing in rupees for your number of doctors

Book a demo

We'll use your details only to arrange the demo, and call you to fix a time.
