SMS Reminder turns your Shopify store into a booking store. Customers pick a time and book themselves in, and you manage everything from your Shopify admin. Taking bookings is free forever — you can charge for appointments through Shopify checkout or collect payment in person. SMS reminders are an optional paid add-on when you're ready to cut no-shows.
Setup is three steps inside the app (it tracks your progress, "2 of 3 steps complete"), with a short one-time onboarding in between.
What you'll need
A Shopify store
A Google account for your calendar
No coding required.
Step 1 — Finish your SMS Reminder setup
Install SMS Reminder Appointment Booking from the Shopify App Store and open it from your admin. On the Connect SMS Reminder card, click Continue to SMS Reminder and sign in:
Continue with Google using the account for your calendar, and approve the permissions.
You'll land in a short onboarding that sets up your booking basics:
Set your availability — turn on the days you work and set start/end times (you can copy one day's hours to the others, and block out holidays).
Create your first appointment type — give it a name and duration, and set options like minimum notice, buffers, rescheduling, and which Google calendar it books into. (On the free plan you can link your primary calendar; syncing more needs an upgrade.)
SMS reminders (optional, paid) — you can switch on automatic reminders and set the message now, or skip and do it later. Reminders are a paid add-on — you get a free trial of 25 messages, then a plan. Your bookings stay free either way.
Finish with Finish & Get my Booking Page, then let it take you back to the Shopify app. Step 1 now shows Done.
Step 2 — Link a booking product to an appointment type
An appointment is sold as a Shopify product, and the product's price is what your customer pays. In the Setup guide, open Link a booking product to an appointment type.
Click Choose product and pick the Shopify product you want customers to book (or Browse products in Shopify to create one — see below).
In Link it to an appointment type, choose the appointment type you made in Step 1.
Click Link appointment type.
You can link several appointment types to the same product.
Creating the booking product. If you don't have a product yet, use Browse products in Shopify → Add product and set it up like this, then return to the app and use Choose product:
Title — the service name customers see (for example, "Wellness Session").
Price — what the customer pays. Set it to $0 to collect payment in person or offer a free consultation.
Turn Track inventory off — availability comes from your open calendar slots, not stock.
Turn This is a physical product off — so Shopify doesn't add shipping at checkout.
Step 3 — Enable the "Book Now" button
The last step turns on the button customers use to book. In the Setup guide, open Enable the "Book Now" button and click Open theme editor.
In the theme editor, open App embeds.
Turn on SMS Reminder Booking.
Click Save.
Back in the Setup guide, click I've enabled it.
On a linked product, the Book Now button now replaces Add to cart. (Want to change how it looks? See Turn on the Book Now button for the button colour, size, and label defaults.)
Step 4 — See what your customers get
Open a linked product on your storefront and click Book Now. Customers pick a date and time, enter their name and phone number, and add the booking to their cart to check out through Shopify checkout. Once checkout is complete the slot is confirmed, syncs to your Google Calendar, and shows in your upcoming appointments in the app.
If you priced the product at $0, the booking is confirmed without a checkout payment, and you collect in person.
Good to know
Bookings are always free — there's no per-booking fee to use the app, whether you charge at checkout or collect in person.
Deposits and partial payments aren't supported yet — a paid appointment is charged its full price at checkout.
SMS reminders are the paid add-on. You get a free trial of 25 messages (about 12 bookings with reminder and confirmations), then a plan. If the trial runs out, SMS pauses but your bookings keep working — upgrade any time. See Plans & billing.
Editing later — your appointment types, availability, and booking page live in the SMS Reminder web app Settings > Booking Page ; reach them from the app's Edit appointment types and Edit availability links.
Switched themes? App embeds don't always carry over — if you change themes, re-enable SMS Reminder Booking in the new theme.
