You can limit future appointments by adjusting the Booking Limit on each of your calendars. By default this is set to 360 days, meaning people can book almost a year in advance. 

If you'd rather only accept online appointments 30 days or 90 days out, you can limit this in your settings. 

1. Log in to BookedIN
2. In the top menu, go to Settings > Calendars
   
3. Click Edit on the calendar you want to modify
   
4. Under Advanced Options, change the Booking Limit. Ex: if you only want to accept public online bookings 3 months out, change the Booking Limit to 90 days. Note: this only affects your public online booking page
   
5. Save
6. Repeat for any other calendars
