Collection: SMS Reminder for Shopify → Selling & bookings
Availability controls when customers can book. Set it so people only see times you're actually open.
Open your availability settings
In the Shopify admin, open the app and find the Availability section — it shows your current hours for each day. Click Edit availability to change them (this opens Settings → Booking Page → Manage availability in the web dashboard). You first set these during onboarding.
Set your hours
Turn on the days you work and set start and end times for each. Customers are only offered open slots inside those hours, and your Google Calendar's busy times are blocked automatically. You can also block out full-day holidays.
Appointment Type Notice periods and buffers
Fine-tune how bookings land within the web dashboard Settings > Booking Page > Manage appointment types
Minimum notice — stop last-minute bookings (for example, no bookings within 2 hours).
Buffers — add gap time before or after appointments so you're not booked back-to-back.
Appointment length
Each appointment type has its own length. To change a duration, edit the appointment type — see Create your first appointment type.
