Phone booking
A client calls and books Thursday at 2. You type the appointment into Google Calendar the same way you always do. Etisia handles the reminder layer on top.
How to Keep Google Calendar and Still Send SMS Reminders
If Google Calendar already runs your appointments, you do not need to replace it to send SMS reminders. Etisia connects to the same calendar you already use and adds the reminder layer on top. Phone bookings, text bookings, DMs, walk-ins, booking links — it does not matter how the appointment got there. If it ends up in Google Calendar, your clients can get reminded.
Keep Google Calendar. Add SMS reminders. Change almost nothing.
Most businesses do not have one clean booking flow
Real appointment businesses rarely book through one tidy system. Some appointments come in by phone, some by text, some by Instagram DM, some in person, and some through a booking link. Google Calendar is where all of that ends up.
That is why migration feels wrong.
The problem is usually not your calendar. The problem is that Google Calendar does not send client SMS reminders on its own.
The fix should add the missing reminder layer — not replace the system your team already knows.
What stays the same — and what changes
This is the real question behind migration fear. Not "what features does it have?" but "what do I actually have to change?"
| What stays the same | What changes |
|---|---|
| You still create and edit appointments in Google Calendar | Clients start receiving SMS reminders automatically |
| You still book however you already book — phone, text, DM, walk-in, booking link | Every reminder includes a cancellation link |
| Your team still uses the same shared calendars | Reminder status becomes visible on calendar event titles |
| Upcoming appointments already on your calendar stay there | If a client cancels through the link, you know quickly and can refill the slot |
The calendar stays yours. The reminder layer is what changes.
How real businesses actually book appointments
These are not edge cases. This is normal.

No app needed
Instagram or text booking
A client messages you, you agree on a time, and you add it to your calendar manually. No booking link needed. No new app for the client.

The reality
Mixed booking sources
Some appointments come from a booking link, some by phone, some in person, and some by text. It does not matter. If the event lands in Google Calendar, Etisia works from there.
Setup steps
How to set it up
Connect your Google Calendar
Sign in with Google and connect the calendar you already use. Upcoming appointments are picked up automatically, including bookings already on your calendar.
Connect it once and keep Google Calendar as the source of truth for every appointment that is already on the books.
Set your reminder timing
Choose when reminders should send before the appointment. This is a one-time setup, not a new booking process, and it applies on top of the calendar workflow you already use.
Set the reminder windows once, then let the timing layer run quietly in the background.
Pick your SMS template
Choose the reminder text your clients will receive. Start with a ready-made template or tweak the wording so it sounds like your business, then save it as part of the one-time setup.
The calendar stays the same. This step just defines what the reminder layer says.
Turn on the useful options
Enable the extras that make the reminder workflow practical: cancellation links, quiet hours, opt-out handling, and reminder feedback inside Google Calendar.
These settings make the reminder layer easier to trust and easier to manage once it is live.
Send a test SMS to yourself
Before going live, send one reminder to your own phone and check the full experience: the text itself, the cancellation link, and how the appointment status shows up in Google Calendar.
One end-to-end test makes sure the reminder layer looks right before real clients see it.
Keep booking the way you already do
Phone, text, DM, walk-in, booking link — none of that changes. Add the appointment to Google Calendar the same way you already do. For brand-new clients, include the phone number once, then let the reminder layer run automatically on top.
The booking flow stays in Google Calendar. Etisia just needs enough information to resolve the client number.
FAQ
Do my clients need to download an app or use a booking link?
No. They receive a plain SMS. Nothing to install, no account to create.
I book by phone and type events manually. Does that work?
Yes. That is one of the main workflows this page is for.
Do I need to recreate appointments already on my calendar?
No. Existing upcoming appointments stay where they are. You do not need to rebuild your schedule.
Does Etisia replace or move my calendar?
No. Google Calendar stays your working calendar. Etisia adds the reminder layer on top.
What if some bookings come from a booking link and others don't?
That is fine. If the appointment ends up in Google Calendar, Etisia works from there. It does not matter how the event was created.
Does this work with shared calendars and Google Workspace?
Yes. Both personal Gmail and Google Workspace calendars are supported.
