# Can I allow bookings with no minimum advance notice?

Updated October 26, 2026 1 min read

Yes. In **My Business → Settings**, under “Booking rules”, set “Minimum advance to book” to “No minimum”. It saves on its own and applies to every channel: website, widget, chatbot and phone.

With “No minimum”, customers can book any free slot from this moment on. Everything else still applies: your hours, existing appointments, blocked time and each service’s timing.

Keep in mind:

- If a service has its own “Minimum notice (hours)” (in **My Business → Resources & Services**, under the service’s “Additional timing”), that value is the one used for that service. Leave it empty to use the general one.

- If you take last-minute bookings, turn on “New appointments” in **My Business → Notifications** (“Business Notifications”) and click “Save Changes” so you hear about them as soon as they come in.
