You can edit or delete an existing Business Profile by tapping the Ripl menu, then "Business Profile Settings." This will pull up the "Current Business" profile where you can tap the "Edit" button to change the name or type of business. At the bottom is the option to "Delete Business."
On the web app, you can do the same by clicking on the "My brand" tab then selecting "Settings." In the lower left corner is the button to "Delete This Brand."
Something to keep in mind: The option to delete the business profile is only available if you have more than one business profiles in Ripl. If you only have one business profile in the Ripl app, you will not see the option to delete it.
