For the SMS Reminder Shopify app. Using SMS Reminder with Google Calendar instead? See the general help center.
This step is required. The Book Now button is how customers book from your store. It's a theme app embed you turn on once — no code, no dragging blocks into place.
Turn it on
In SMS Reminder in your Shopify admin, open the Setup guide step Enable the "Book Now" button, then 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.
What customers see
On any product you've linked to an appointment type, the Book Now button now takes the place of Add to cart. Customers pick a date and time, enter their details, and check out through your normal Shopify checkout. If the product is priced at $0, the customer still completes checkout, with no payment required. Every booking syncs to your Google Calendar.
You can verify it in two ways:
In the Shopify in-app Admin, go to the Appointment types section → Actions → View
View the product in your online store directly
Don't see Book Now on a product? It only appears on products that are linked to an appointment type — see Link a product to an appointment type. If it's still not swapping, see Your product still shows "Add to Cart" instead of "Book Now".
Customize how the button looks (optional)
You can style the button from the app's Booking button defaults section ("Customize how your booking button looks on product pages"):
Button label (default Book Now)
Background color and Label color
Button size
Positioning
Set them and click Save defaults. These apply to the Book Now button on your linked products.
Prefer to share a link instead?
You also have a shareable booking page you can send to clients or add to any website — find it in the Shopify app admin panel under Upcoming booked appointments → Share your booking page → Copy, for quick access.
It's a handy alternative for older themes or for booking outside your store.
Switched themes?
App embeds don't always carry over. If you change or update your theme, re-enable SMS Reminder Booking in App embeds on the new theme.
