One calendar, one copy, no new system to check. Open Lines reads the same Google Calendar you already live in and writes the appointment into it while the caller is still on the phone.
Free for 7 days, cancel anytime. Live in under 10 minutes.
Google Calendar suits businesses that run on one diary rather than a booking system — a few people, a shared view, and whatever anyone has blocked out. Open Lines treats that diary as the single source of truth: it reads what is genuinely free at the moment a caller asks, and writes the appointment in as an ordinary event. There is no second calendar to reconcile, because there is only ever one copy.
An ordinary Google authorisation from your dashboard. No plugin to install and nobody’s permission to ask for.
A school run, a supplier meeting, a block you added yourself — each one makes that time unofferable.
On the phone in your pocket, in the view your team already has open, with the caller’s details attached.
The slot is written down in the same moment it is offered, which is what actually prevents a double booking.
Nothing to keep in sync and no booking calendar to remember to check, because the appointment lives in the only calendar you have.
Personal commitments in the same calendar protect your time automatically — which is the argument for keeping them there.
The same calendar your phone already shows. There is no separate booking calendar to check, and nothing to keep in sync, because there is only ever one copy.
Anything already in your calendar makes that time unavailable — a school run, a supplier meeting, a block you added yourself. The assistant cannot offer a time you have already spoken for.
It offers times inside the hours you set rather than any gap in the day, so nobody gets booked in at seven in the morning because the calendar happened to be empty.
The connection is an ordinary Google authorisation, visible in your Google account alongside every other app, and removable from there at any time without contacting anyone.
Your primary Google Calendar — the one your phone already shows. There is no separate booking calendar to keep an eye on.
No. Anything in your calendar makes that time unavailable, including personal blocks you added yourself.
Yes. It offers times inside the working hours you set, rather than any gap that happens to be empty.
It asks for calendar access, and you can see exactly what was granted in your Google account’s security settings at any time.
From your Open Lines dashboard, or directly in your Google account alongside every other connected app. It takes effect immediately.
The appointment is created in your calendar with their details, and they receive a confirmation from Open Lines by text or email.
