Weekly availability answers one question: which hours am I generally free. That is the easy part, and on its own it produces a booking page that will happily schedule a client four minutes from now, put six sessions back to back with no gap, and take a booking for a Tuesday in March you have not thought about yet.
Four settings fix that. They are the difference between a page that fills your calendar and one that protects it.
Buffers: the gap around a session
A buffer is padding before or after a booking that nobody else can take. After a session it is where notes, follow-up emails, and the walk to the kettle happen. Before one it is preparation time.
Ten to fifteen minutes after each session is the setting most people should start with. If your sessions routinely overrun, put the buffer after rather than lengthening the session, so the extra time is yours rather than the client's by default.
Minimum notice: the earliest someone can book
This is how much warning you need. Without it, a slot that starts in ten minutes is bookable, which is how you end up in a call you did not know about while making lunch.
Four hours is a reasonable floor for most work. Twenty-four is common for anything needing preparation. Push it much beyond that and you start losing genuinely urgent bookings, which for consultants and anyone doing discovery calls is often the good kind.
Booking window: how far ahead
The opposite limit. A window that runs indefinitely means somebody can book you for a date so distant that your plans will have changed twice by the time it arrives, and those bookings cancel at a much higher rate.
Thirty to sixty days suits most practices. Shorter for anything seasonal, longer for work that genuinely gets planned a quarter out. The window also has a quiet second effect: it stops your calendar filling with commitments you made before you knew what next month looked like.
Date overrides: the exception to everything
Weekly rules describe a normal week. Date overrides handle the weeks that are not: a public holiday, a conference, a Friday you are taking off, or a Saturday you are opening specially because a client is flying in.
The important thing is what an override is not. Blocking one Thursday should never mean switching off Thursdays. An override applies to a single date and leaves the weekly pattern intact, which is exactly what you want when you get back from the conference and stop thinking about it.
A starting configuration
- •Buffer: 15 minutes after each session.
- •Minimum notice: 4 hours, or 24 if you prepare for sessions.
- •Booking window: 45 days.
- •Date overrides: holidays and known travel, added the moment you know about them.
Then adjust from what actually goes wrong. Sessions running into each other means a longer buffer. Being ambushed means more notice. Distant bookings cancelling means a shorter window.
Why it matters more than it sounds
These four settings are where self-service scheduling either earns trust or loses it. Get them right and handing out a booking link feels safe, which is the whole point of letting clients book themselves. Get them wrong and you spend your week rescheduling, which is the situation you were trying to leave. Set yours up.
