Two-way sync with Google Calendar
You already live in Google Calendar. Connect it once, and Waine stops a client from ever booking over your dentist appointment or your kid's soccer game — without you having to check two calendars before saying yes to anything.
Sign upHow it works
01
Connect Google
Link your Google account from settings in a couple of clicks.
02
Bookings sync out
New Waine appointments appear on your Google Calendar automatically.
03
Busy times sync in
Personal events on Google block those times in Waine so clients can't book over them.
The two calendars stop fighting each other
It really does go both ways
Book someone in Waine and it lands on Google. Add a dentist appointment on Google and Waine quietly blocks that hour on your public page — you don't have to remember to do either side manually.
No more "wait, I'm double-booked"
Whatever's already on your connected calendar just disappears from the slots clients can pick. They see an open hour or they don't; they never see the reason why.
One calendar, not a shared team one
This connects the actual business owner's calendar — the one with your dentist and your kid's soccer game on it, not a generic staff schedule.

Frequently asked questions
Does Waine actually sync both ways, or just one?
Both ways. Book something in Waine and it shows up on Google. Add something on Google and it blocks that time in Waine — neither calendar has to be your "real" one.
So I genuinely can't get double-booked anymore?
Right — as long as it's on your connected Google Calendar, Waine treats it as busy and won't offer that slot to a client, full stop.
Which calendar do you connect — mine, or the whole team's?
Yours specifically — the business owner's own calendar. That's usually where the personal stuff lives that actually causes double-bookings.
Stop checking two calendars before you say yes
Connect Google Calendar in a couple of clicks and let Waine sort out the rest.
