How do I stop double bookings when two staff members share one calendar?
Set up separate staff columns
Most booking tools let you view each person as a separate column or calendar. Keep each stylist or technician on their own schedule so the system knows who is free at any given time. A combined view is useful for you to look at, but the booking engine should check availability per person.
Once columns are separate, make sure every service is tied to the people who actually perform it. A color service that only one person offers should not appear as an option when someone else is free.
- Give every staff member their own login or profile
- Assign each service only to the people who perform it
- Block lunch and admin time on each calendar
- Turn on conflict warnings if your app offers them
Protect shared rooms and equipment
Double bookings often happen with a chair, room, or machine rather than a person. Create each shared resource as its own item in the software and require it when a booking is made. If two appointments both need the same treatment room, the second one should fail to save.
Test the setup by booking two overlapping appointments yourself. If both go through, check whether the resource is linked to the service and whether overlap rules are switched on. Setting names differ by product, so look for resource, room, or equipment options in the service editor.
Common mistakes
- Letting staff share one calendar with no individual availability, which hides real conflicts.
- Forgetting to attach rooms or equipment to services, so the system never checks them.
