Toolio should automatically have all the brands you have previously bought from. If there are new brands you are bringing in the business and would like to add it to Toolio, you can easily do that in the organization section.

Go to the organization > brands section in Toolio. There you should see a list of all brands in your organization:

Click Add Brand  on the top right, which brings a pop-up where you can add the brand details:

Once you hit Create  the new brand will have been added! You should be able to see that brand in all other screens and in the add-in after this.
