The default is wrong for almost everyone
A booking tool out of the box offers every slot from opening to closing, back to back, with no gaps. That is fine for a video call. For anyone who cleans a room between clients, drives between jobs, writes up notes or simply needs five minutes, it produces a diary that looks full and a day that is impossible.
Most owners discover this by living it: a client books 2:00 the moment the 1:00 ends, and the tool was doing exactly what it was told. The fix is configuration, and it takes an hour.
Buffer time
Every serious booking tool has a buffer setting: time blocked before or after each appointment that clients cannot book into. Set it to what you actually need, not what you wish you needed.
- Clean-down and reset: salons, clinics, therapists, tattoo studios. Usually 10 to 15 minutes after.
- Notes and admin: counsellors, coaches, consultants. 10 minutes after.
- Preparation: anything needing set-up before the client arrives. 10 to 15 minutes before.
- Simply breathing: 5 minutes after, for anyone whose day is otherwise relentless.
Buffers can differ per service. A quick consultation may need none; a full treatment needs fifteen minutes after. Configure per service where the tool allows it.
Travel time for mobile businesses
Dog groomers, mobile hairdressers, personal trainers, cleaners, tutors, trades. Travel is the gap that generic buffers handle badly, because it varies by where the last job was.
Options, from simplest to best:
- A fixed generous buffer of 30 to 45 minutes after every job. Simple, and it wastes time when jobs are close together.
- Service areas with separate calendars or days. Mondays in the north of town, Tuesdays in the south. Clients choose their area and see only those days. Reduces travel by grouping.
- Tools built for mobile work that calculate travel between consecutive bookings from the addresses. Housecall Pro, Jobber, ServiceM8 and some scheduling tools do this. Worth it for anyone driving between more than four jobs a day.
Whatever you choose, ask for the address at booking so you can see the day's geography before it happens.
Set-up and clean-down that spans appointments
Some businesses have a fixed set-up at the start of the day and clean-down at the end that has nothing to do with individual appointments. Do not model that as buffers. Set your available hours to exclude it: if you open at 9 but need 30 minutes to set up, your bookable hours start at 9:30.
Minimum notice
How close to the appointment can someone book? The default is often "any time", which means a booking for 10 minutes from now that you see when you check your phone at lunch.
Set minimum notice to what you can genuinely respond to. Two hours for a business with someone watching the diary. A day for a sole trader who is with clients all day. Same-day bookings are valuable; same-minute bookings are chaos.
Maximum advance
How far ahead can someone book? Too far and you have bookings for months you have not planned yet, holidays not blocked, prices not set. Sixty to ninety days suits most small businesses.
Slot intervals
The tool offers start times at some interval: every 15, 30 or 60 minutes. Shorter intervals give clients more choice and fragment your day; a 45-minute service on 15-minute intervals produces unbookable 15-minute gaps. Match the interval to your shortest service, or to your longest if you would rather have tidy hours than maximum flexibility.
Availability that reflects reality
Block out the things the tool does not know about: lunch, school run, the weekly supplier visit, the half-day you always take. Recurring blocks for recurring things. If you have a personal calendar, connect it so a dentist appointment blocks your diary automatically.
Per-staff settings
Each staff member has their own hours, services, buffers and breaks. The part-timer who does Tuesdays and Thursdays should only show those days. The senior who needs longer per client should have longer durations. Configure each person, not one setting for all.
Test it as a client
When the configuration is done, open your booking page on your phone as if you were a client and try to book every service at awkward times: right before closing, right after another booking, tomorrow at 8am. Everything the tool offers you should be something you would actually be able to do. If it offers a slot you would have to cancel, tighten the setting.
Revisit quarterly
Buffers that were right for a new business are wrong for a busy one. Review the settings every three months: are you rushed between clients, or are there gaps nobody can book? Adjust.
This configuration hour is part of every booking system set-up we do, because a booking tool that produces an impossible day teaches the owner to distrust it, and a tool the owner distrusts gets switched off. Configured for how you actually work, it becomes the thing that makes the day run.
