Monday morning, ten past nine. The phone rings while the receptionist is checking in the first patient who arrived. The second caller gets the recorded message; the third hangs up and tries a different practice from the traffic lights.
That call appears nowhere. No line in the diary, no name to ring back. Requests lost on the phone are the item on the balance sheet nobody in the practice manages to count — the same silent arithmetic behind the cost of a missed call.
Opening online booking recovers part of it. Opening it badly creates a new problem: a diary anybody can fill without rules becomes unmanageable within a fortnight, with forty-minute first consultations sitting inside twenty-minute slots. What follows is what to open, under which rules, and how it connects to confirmations and reminders.
What a diary that lives only on the phone costs
Calls cluster at opening, after lunch and in the late afternoon — exactly when the waiting room is fullest. In those windows whoever is on the desk is doing two jobs at once and doing at least one of them badly.
The consequences accumulate quietly. An unanswered request enters no statistic. A slot freed up the day before stays empty because nobody had twenty minutes to work through the waiting list.
Only your practice can do this sum: the average value of a first consultation, multiplied by the slots that went unfilled last month. It is worth doing once, on paper, before deciding anything.
Why the phone, the paper diary and the clinical system all fall short
The phone works while the practice is open. Somebody who decides to book at 21:40 puts it off until tomorrow, and tomorrow they forget.
The paper diary is readable at a glance, but it exists in exactly one copy. A spreadsheet improves legibility and destroys concurrency: two people editing the same file produce two versions of the truth.
The clinical management system deserves its own paragraph, because it is the most common objection. It handles records, reporting and healthcare billing — things no marketing platform can do. Many of them, though, do not offer a page where the patient picks a slot that is locked immediately. They offer a request form: the message lands with reception, reception calls back. The human work stays exactly where it was.
What serious online booking has to do
Write the requirements down before looking at any software. They hold whatever tool you end up with.
Durations per service. A hygiene appointment is not a routine check, and a first consultation is not a follow-up.
Buffer time. Between one patient and the next there has to be room for cleaning, for writing up, and for the person who arrives at 10:02.
Minimum notice and maximum window. Nobody should be able to book at 08:47 for 09:00, and twelve months of open diary is twelve months of rescheduling.
Which services are bookable and which are not. This is the decision that determines everything else, and it gets its own section below.
Confirmations and reminders connected to the booking. If bookings live in one system and reminders in another, somebody has to reconcile them by hand — and sooner or later they stop.
Consent in the right place. The privacy notice belongs inside the form, and marketing consent stays separate from the service data. Confirmations and reminders are service communications tied to the appointment the patient asked for; inviting somebody without an appointment to come back in is marketing, and needs its own consent. We went through that distinction in detail in GDPR and the healthcare CRM.
Which services to open to self-service
The criterion fits in one line: open online everything for which reception does not have to make a decision. If somebody in the practice has to think before fixing the appointment, that service stays on the phone.
Good candidates are services with a fixed, predictable duration — the six-monthly hygiene appointment, the periodic check, the annual recall, the next session in a course of treatment already agreed. Today reception reads the diary and offers two dates: work the patient can do perfectly well themselves.
Staying with reception: first consultations where somebody needs to understand the reason for the request, services whose duration changes with the case, urgent requests, and anybody calling about a problem in progress. A workable middle ground is a first consultation bookable online into a standard slot, followed by a preparatory phone call.
Take ten minutes and split your own list of services into two columns. It is the single most useful document to bring to any supplier — including us.
What changes at the front desk
Requests arrive in the evening and on closing days, and by Monday morning they are already in the diary. During peak hours the phone stops being the only way in, so whoever is greeting patients can actually greet them. Details arrive typed by the patient rather than dictated over a bad line, which means fewer wrong phone numbers. And every booking leaves a record of which services get booked, and in which time bands — a picture the practice has never had before.
The whole path, from link to the next visit
With the system configured, a booking moves like this:
- The patient finds the link — on the website, in the Google listing, in an email signature.
- They choose a slot from the times that are free and compatible with the rules you set.
- The contact enters the CRM: the form becomes a record, the appointment appears in the diary.
- The confirmation goes out automatically, on the channel the practice has chosen.
- The reminder arrives before the visit, at the notice you decide.
- Reception sees the status — confirmed, moved, cancelled. A cancelled slot becomes visible again immediately, in time to reallocate it.
- The follow-up goes out after the visit, at the interval you set.
- The contact enters the right pathway: a six-month recall, the continuation of a course of treatment, or nothing at all if there is no lawful basis to contact them again.
A confirmation that respects the constraints of the sector carries no clinical detail whatsoever:
Dear Mr Rossi, your appointment on Tuesday the 9th at 10:00 at our practice on [address] is confirmed. If something comes up, you can let us know by replying to this message or calling [number]. Thank you.
Two warnings about steps 4, 5 and 7. SMS and WhatsApp are charged per message on top of any subscription, and a badly written sequence gets paid for twice. And every message rests on a lawful basis: a confirmation and a reminder are service communications, while inviting somebody to book something they did not ask for is not.
When online booking is the wrong thing to buy
If you only need a calendar. A practice that just wants hygiene appointments bookable online, with no CRM and no automations, will find specialised tools that are usually cheaper. Compare them properly.
If what you actually need is a clinical system. Patient records, reporting, healthcare billing, national reporting obligations, integration with a laboratory: a marketing platform does none of it. Where the two coexist, the booking platform sits in front and the clinical system behind, with a single point of data entry.
If your clinical system already has decent online booking. Ask the supplier you are already paying before adding a second system. Two parallel diaries produce double the errors.
If nobody wants to own the process. No platform decides which services to open or what the message should say. It executes rules somebody wrote.
If your diary is already full. Online booking does not produce patients you do not have. At best it helps you manage the waiting list.
How to start
On your own, with a trial of whatever tool you are evaluating. The advice is not to open everything at once: one calendar, for the single most repetitive service, and two weeks with reception checking every booking that comes through.
With a partner, if you would rather receive a working system. Here the line is worth keeping clean: calendars, notifications and automations are native functions of the platform, included in the subscription you pay the vendor. The work worth paying somebody else for is deciding what to open, writing the diary rules, configuring compliant notifications and consents, and leaving reception a written procedure. That is what we do on GoHighLevel for medical practices — and since we implement that platform for our clients, we have a direct commercial interest in it, which is worth saying before you weigh anything above.
Common questions
Do older patients actually use it?
Some do, some do not. The channel sits alongside the phone rather than replacing it, and it is often an adult child booking for a parent. The value is in the requests that are lost today, not in moving the ones that already work.
Is marketing consent needed for online booking?
No. Confirmation, reminder and rescheduling notices are service communications, tied to the appointment the patient requested. You still need the privacy notice in the form and a data-processing agreement with the supplier. Marketing consent is what you need to invite somebody who has no appointment booked.
Does it integrate with the clinical system?
It depends on the system: some expose integrations or an API, many do not. Ask the supplier you already pay whether it can accept appointments from outside. If it cannot, keep a single point of data entry rather than running two diaries.
Can I choose which appointments are bookable online?
Yes, and it is the most important decision you will make. Separate calendars get created for the bookable services, each with its own duration and its own hours.
What happens if two patients book the same time?
A calendar shows only free slots and removes them once taken, so the double booking of the paper diary does not recur. Details such as the maximum number of bookings per slot are worth verifying on your own account during a trial rather than assuming.
How long does it take to set up?
Creating a calendar takes minutes. Setting it up well takes a few days, and the slow part is organisational rather than technical: services, durations and compliant wording.
The next step
You already have what you need to decide on your own: the triage of services and the diary requirements to put to any supplier. If you would rather somebody looked at your diary first, get in touch — we can work out together what is worth opening and what is not.
