Buffer time between appointments is unbooked time you keep after each client to clean up, disinfect tools, write notes, take payment and travel. The right amount depends on the service, so time your real changeovers for a week or two and set a buffer for each service. Too little makes you late, and too much leaves gaps.
Back-to-back bookings look efficient on paper. In practice, one service that runs ten minutes over makes every client after it late. A buffer soaks up small overruns before they stack up, and it gives you time for the work that happens between clients:
Cleanup and disinfection. Tools, stations, towels and foot basins.
Notes. Color formulas, what you covered in a lesson, a client's preferences.
Checkout and rebooking. Payment, receipts and the next appointment.
Travel. For mobile services, the drive plus loading, parking and finding the door.
You. Water, a bathroom break and a moment to reset.
For licensed beauty work, your state's rules may decide part of your buffer for you. As one example, California's Board of Barbering and Cosmetology requires non-electrical tools that can be disinfected to be cleaned and then disinfected before use on a client, using an EPA-registered disinfectant according to the manufacturer's instructions. Whirlpool footspas must be cleaned and disinfected after each client, which includes circulating disinfectant through the basin for at least 10 minutes.
So in California, if you have one footspa, your pedicure buffer has to be at least as long as that cleaning routine. Rules differ by state and province, so check your own licensing board and your disinfectant's label.
There's no single right number. Use these as a checklist of what each buffer has to cover, then time it yourself.
Hair, nails, lashes and brows. Cleanup and disinfection under your state's rules, resetting the station, checkout and notes. Chemical services can run long, so give them a bigger buffer than a quick trim.
Mobile services, such as cleaning and detailing. Packing up, the drive at that time of day, parking and a cushion for jobs that run long. Check the drive in a maps app for the real departure time, not for an empty road.
Tutoring and lessons. Session notes, a quick message to the parent and resetting materials. For online sessions, add a few minutes to open the next link and check your audio.
First visits and consultations. New clients take longer: more questions, a form to fill in and a walk-through of what to expect.
Time your changeovers. For a week or two, note when each client leaves and when you're truly ready for the next one.
Pick a buffer that covers most of them. Plan for a normal day, not the one-off disaster.
Build it into your booking blocks. A 60-minute service with a 15-minute buffer takes a 75-minute block on your calendar. The client still books a 60-minute service.
Review it each month. Running late often? Add time. Sitting idle? Trim it.
Example (numbers for illustration only): you time eight changeovers after gel manicures at 9, 11, 12, 10, 14, 9, 18 and 11 minutes. Seven of the eight took 14 minutes or less, so a 15-minute buffer covers a normal day, and the 18-minute one was a one-off.
Many calendar tools can add the buffer for you. Google Calendar's appointment schedules, for example, include a buffer time setting that adds time between appointments, though Google notes that some appointment schedule features need an eligible Google Workspace or Google One subscription.
Example only: a cleaner books a 3-hour clean at 9:00 a.m. The next home is a 20-minute drive away.
9:00 a.m. to 12:00 p.m.: the clean
15 minutes: pack up and load the car
20 minutes: drive to the next home
15 minutes: cushion for traffic or a clean that runs over
The next clean should start at 12:50 p.m. Booking it at 12:00 or 12:15 would make the cleaner late before the afternoon even started, and every later client would feel it.
Buffers cut down on lateness, but some days still go sideways. Decide your plan before it happens:
Message the next client as soon as you know. Give a real time, not "a bit late".
Offer a choice. A slightly later start, a shorter service or a new time.
Keep one flex block. An unbooked 30-minute block in the middle of the day lets you catch up before the afternoon.
Protect the end of the day. That's where delays pile up, so don't squeeze an extra client into the last slot.
A text you can copy: "Hi [name], I'm running about [15] minutes behind today. I can still see you at [time] for your full [service], or move you to [other time] if that's easier. Which works better?"
When it's the client who's running late, our sister site has templates for what to text a late client. And if your whole week feels crowded, time blocking can help you protect admin time too.
Enough to clean up, reset and take payment on a normal day, plus travel for mobile work. Time your own changeovers rather than copying someone else's number.
They don't need to. Book the service at its real length and block the buffer on your side, so clients aren't confused about how long the appointment lasts.
Not as a separate line, but your prices need to cover it. It's working time, even when nobody is in your chair.
Buffer time is for the work between clients. A break is for you. If cleanup keeps eating your buffers, schedule real breaks as well.
BookingSolved: Client Booking is a free iPhone app, with optional Pro upgrades, that turns appointment requests from texts, screenshots or the Share Sheet into Apple Calendar bookings and suggests open times within your business hours around existing appointments, using each service's duration and buffer time. Its starter presets for salons, cleaning, tutoring and more come with durations and buffers you can edit, and it re-checks Calendar before saving so a double tap doesn't create a duplicate booking.
