Service categories make the booking journey for your customers clearer and allows the business owner to organize their activities. For example, a hair and beauty salon may have one category called Haircuts with all the different styles allocated to it, and another category called Beauty and Nails with all the treatments that they offer categorized to it.
To create a new category:
Hover over Your business tab
Click the Add category button and input a name
Now, whenever you create a new service you will be asked which category it should be placed in.
If you wish to edit a category then you can do so by clicking on the pencil icon next to the category name.
