As a Manager, you have the ability to update the information related to your location(s). This can be done by going to your Locations tool (found under System in your toolbox).
What you will see here depends on your account group and account setup. Area and General Managers that manage multiple locations will be presented with a list of the locations that are available for modification.
From here, clicking the name of the location will take you to the location update page where you will be able to make changes to the information about your store. Store Managers will immediately see this page, as they have only a single store to manage.
For information about the different options that are available when updating your location, please see Creating a Location.
