Buffer time between appointments: how much, where, and for which services
How to size buffers before and after appointments for clean-down, notes, travel and overruns, set different buffers per event type, and know when a longer appointment is the better answer.
A buffer is protected time attached to an appointment that clients cannot book. It is the ten minutes to wipe down a treatment couch, the quarter of an hour to write up notes, the drive between two jobs or the cushion that absorbs a session that runs over. Without buffers, a booking page will happily put clients back to back, and every small delay rolls forward into the rest of the day.
Getting buffers right is mostly about measuring what actually happens between appointments, then setting different amounts for different services. This guide explains before and after buffers, how to size them, when to lengthen the appointment instead, what clients see and how to review your settings after a month. If you are new to booking pages, start with how online appointment scheduling works.
Before buffers, after buffers and how to size them
Most scheduling tools, Calenix included, let you add buffer time to an event type so it is applied every time that appointment is booked. The booking page then hides start times that would leave too little room either side.
Before or after?
A before buffer protects time ahead of an appointment. Use it for set-up and preparation: laying out equipment, reading the client's booking answers, preparing a stencil, testing a video link or getting to a client's address. An after buffer protects time once the appointment ends. Use it for clean-down, notes, payment, follow-up emails, packing up and the inevitable overrun. Where your tool lets you set the two separately, split the time by what it is for. Where it offers a single buffer, add the two together.
Sizing by reason
- Clean-down and turnaround: time it. Changing linen, sanitising surfaces and resetting a room takes a fairly predictable amount of time, and any hygiene rules your profession or local authority sets will shape it.
- Notes and admin: five to fifteen minutes is common for consultations where you write up while it is fresh. If you never actually write notes between sessions, do not pretend you do; batch them into a protected admin block instead.
- Travel: base it on the realistic drive at that time of day, plus parking. For mobile services, a travel buffer is often the biggest single factor in how many jobs fit in a day.
- Overruns: look at how often sessions run long and by how much. A short after buffer that absorbs a typical overrun is better than one that covers the worst case every time.
- Back-to-back video calls: even five minutes to stand up, refill water and read the next person's details makes a noticeable difference by mid-afternoon.
Different buffers per event type
A single global buffer is rarely right. A 20-minute phone consultation needs almost nothing; a two-hour treatment with a full clean-down might need 30 minutes. Set buffers on each event type rather than accepting one figure for everything. On Calenix, the Free plan includes one event type, and the Individual plan allows unlimited event types, each with its own settings.
Buffers or a longer appointment?
If the extra time is part of the service the client receives, such as aftercare advice or a summary at the end, make the appointment longer. If it is time the client is not present for, such as clean-down or travel, use a buffer. The difference shows up in what clients see: a 60-minute appointment with a 15-minute buffer is advertised and confirmed as 60 minutes; a 75-minute appointment is advertised as 75 minutes and appears that way in their calendar.
What clients see
Clients do not see the buffer itself. They see the appointment length in the description and confirmation, and fewer start times on the booking page. If buffers are too large, your page looks fully booked when you are not. If they are too small, clients see plenty of choice and you spend the day running late.
Why buffers decide how your day actually feels
A diary can look perfectly efficient on screen and still be exhausting to work through. Back-to-back appointments leave no room for anything that is not the appointment itself, so clean-down gets rushed, notes are written at 9pm and the fourth client of the day waits fifteen minutes. Buffers are how you build the real shape of the work into the schedule.
They also protect the client experience. Someone arriving to a room that has not been reset, or joining a video call that starts late because the previous one overran, notices. Reliable start times are a quiet but important part of why clients rebook.
There is a cost, of course. Every buffer is time you cannot sell, and buffers that are too generous show up as gaps nobody can book. That is why sizing per service and reviewing after a month matters more than picking a round number. The right buffer is the smallest one that keeps you on time.
Finally, buffers interact with everything else in your availability: working hours, the calendars you connect and the lengths of your appointments. Our guide to avoiding meetings outside business hours covers the working-hours side, and how calendar sync prevents double bookings explains how buffers sit alongside your other commitments.
What well-sized buffers do for you
On-time starts: a typical overrun is absorbed before the next client arrives.
Proper turnaround: rooms, equipment and kit are reset properly instead of rushed.
Notes written while fresh: a few protected minutes beat an evening of catching up.
Realistic travel: mobile appointments stop depending on perfect traffic.
Honest durations: clients are booked for the time they actually receive, with set-up and clean-down kept separate.
A calmer day: small gaps between appointments reduce the end-of-day fatigue of non-stop sessions.
Setting your buffers in 7 steps
Time a week of real turnarounds — For each service, note when the client leaves and when you are genuinely ready for the next one, including clean-down, notes, payment and travel.
Split the time into before and after — Put preparation and travel in a before buffer and clean-down, notes and overrun cushion in an after buffer, or add them together if you only have one setting.
Set a figure per service — Use the typical turnaround, not the worst day. Round to five minutes and write the figure next to each service.
Decide what belongs in the duration — Move anything the client is present for, such as aftercare or a wrap-up, into the appointment length itself.
Apply buffers to each event type — Add the buffer settings on every event type in your booking tool rather than relying on a single default.
Check your page as a client would — Open your booking page on a phone for a typical day and count the start times on offer. If the day looks too thin or too packed, adjust.
Review after a month — Compare how often you ran late with how often you sat idle, and trim or extend each buffer by five minutes accordingly.
Buffer reasons compared
| Feature | Usually before or after | How to size it | Watch out for |
|---|---|---|---|
| Set-up and preparation | Before | Time your usual set-up | Prep that could be done once at the start of the day |
| Clean-down and turnaround | After | Time a full reset, following any hygiene rules | Rushing when sessions overrun |
| Notes and admin | After | Five to fifteen minutes for most consultations | Buffers you spend on something else |
| Travel between jobs | Before | Realistic drive at that time of day plus parking | School-run and peak-hour traffic |
| Overrun cushion | After | Typical overrun, not the longest ever | Covering every worst case and losing slots |
| Reset between video calls | After | Five to ten minutes | Skipping it on your busiest days |
Practical tips for buffer settings
Base buffers on timed turnarounds, not on a number that sounds sensible.
Give each event type its own buffer; a quick call and a long treatment rarely need the same.
Keep the advertised duration equal to the time the client actually spends with you.
Put recurring admin into a protected block in your calendar rather than inflating every buffer.
Recheck travel buffers when you take on a new area or the season changes traffic patterns.
Count bookable start times on a typical day before and after any change, so you see the trade-off.
Review buffers monthly for the first three months, then quarterly.
Buffer mistakes to avoid
Using one global buffer for every service, so short calls are over-protected and long treatments rushed.
Padding the appointment duration with clean-down time, so clients think they are getting longer sessions.
Setting buffers for the worst day you can remember and wondering why the page looks fully booked.
Forgetting that travel only matters between locations, not between two clients at the same address.
Adding buffers in the booking tool and also typing manual gaps into your calendar, doubling the effect.
Never revisiting buffers after the first week, even when services or locations change.
Example: a tattoo and piercing studio in Swansea
A fictional two-artist tattoo and piercing studio in Swansea moved from Instagram messages to a booking page in autumn 2026. In the first fortnight, artists were starting late most afternoons, and piercing clients were waiting while stations were cleaned down.
The owner timed a week of turnarounds, worked out the time needed before and after each service, and entered it on each event type in Calenix, using the Individual plan for unlimited event types:
- Design consultation (20 minutes, video): no before buffer, 10 minutes after for notes and a reference board.
- Ear or facial piercing (20 minutes): 10 minutes before to set up a sterile tray, 15 minutes after for clean-down and aftercare paperwork.
- Small tattoo (60 minutes): 15 minutes before for stencil and set-up, 30 minutes after for wrapping, clean-down and station reset.
- Half-day session (3.5 hours): 20 minutes before, 30 minutes after.
Aftercare explanations, which clients are present for, were moved into the appointment length rather than the buffer. Consultations stay at 20 minutes because there is nothing to clean.
After a month the artist reviewed the results. Piercing clean-downs were finishing early, so that after buffer dropped to 10 minutes, which put one extra piercing slot into most Saturdays.
The illustrative maths: one extra £40 piercing on each of four Saturdays is £160 a month, or about £1,920 a year, from trimming five minutes off a buffer that had been set too cautiously.
