How to add buffer time to a service?

To add a buffer time, please follow the instructions below:

Go to "Settings"-->"Service". Either "add" a service or "edit" to select an existing service.

1. Add "Buffer time" in the service duration. For example: If the service takes 30 minutes and buffer time is 15 minutes then the service time should be 45 minutes.
2. Include actual service duration in the "Name of Service". For example, if the name of your service is "Hair Color" then rename it to "Hair Color (30 minutes)". 
3. Hide service duration (which contains buffer time) from clients. 
   Go to SETTINGS --> BOOKING RULES option.--> Service Option --> Show service time duration to your clients?
