How does an AI receptionist book into my calendar?

Two different products get sold under the word booking. One takes a request and leaves a task for someone to handle later. The other reads your calendar, offers slots that exist, and writes the appointment during the call.

The difference shows when a caller is choosing between you and the next business on the list. A confirmed Tuesday at nine ends the search, and a promise to call back doesn't.

Ask any vendor one question: does it write to my calendar during the call, or after it? Also ask whether booking costs extra. Rosie keeps booking on its $149 plan, as of September 2026.

Connect Google Calendar or Microsoft Outlook in GreetKeeper's settings. Both write directly, and the appointment appears while the caller is still on the line.

Set your appointment types and how long each takes, such as a 90-minute install and a 20-minute estimate. Add how far ahead callers can book and the earliest time of day.

Make the calendar tell the truth. Put every job, school pickup and supplier run into it, and check that personal events show as busy rather than free.

Book a test appointment from a different phone. Check it landed on the right calendar, at the right time, with enough detail in the notes to turn up without calling back.

Say you're a mobile dog groomer working out of a van with Google Calendar as your diary. You set two appointment types: a full groom at 90 minutes and a nail trim at 20. Then you tell the assistant it can book up to three weeks ahead and never before 9am.

On Thursday at 7:40pm, while you're eating dinner, a caller wants a full groom for a goldendoodle this Saturday. The assistant reads the calendar, finds two gaps long enough, and offers 10:00 or 1:30. She takes 1:30. The event appears on your phone with her name, her number, the address and the breed in the notes, and she hangs up with a confirmed time.

Without the calendar write, that same call becomes a message you see at 9pm, a callback she misses on Friday, and a fair chance she's booked someone else by the time you reach her.

An assistant can only respect what the calendar shows. If half your jobs live in your head, on a whiteboard or in a paper diary, it will happily offer those hours to the next caller. Before you switch booking on, spend one evening putting everything into the calendar, including school pickups and the Wednesday supplier run.

Check how personal events are marked. Most calendars let an event show as busy or free, and a dentist appointment saved as free won't block anything. All-day events deserve a look as well, since some block the whole day and others block nothing.

Travel time is the groomer's real constraint, and it's yours if you work on site. Work out the gap you need between jobs and ask how to add it before the first booking. Then make a test booking yourself, from a different phone, and check three things: it landed on the right calendar, in the right time zone, with enough detail that you could turn up without calling back. For any system connected through Zapier, repeat the test and time how long the booking takes to appear.

GreetKeeper offers real slots, takes the one the caller picks, and reads the name, number and time back before it books. After the call, the caller gets one text with the booking confirmation.

Each number can have its own calendar, hours and greeting, so a second location books into its own diary. Closure dates stop anyone booking a day you're shut.

Field-service and practice systems such as ServiceTitan, Jobber and Clio receive the booking through GreetKeeper's webhook and a Zapier flow on a paid Zapier plan. Each booking also fires a booking.created event for your own tools.
