If you have multiple different locations, then FlexBooker can support them all from a single account!
To enable multiple location support, go to Settings -> Manage Locations:
This will display the locations management page.
Since you don't have multiple locations set up currently, you will just see the button to add our first location. This will guide you through the process of adding both the initial location and an additional one. Don't worry, the first location is included in the price of your account, so you will only be charged for the second location and additional ones beyond that.
