The limit varies based on your subscription plan:
Free Trial: 1 brand
Starter: 1 brand
Professional: 5 brands
Teams: 10 brands
The brand quota is fixed, and it does not renew or reset. The number of brands is calculated by the current individual brands within your Brand Kit. Changes to your brands do not count toward your brand limit.
What if I run out of brands?
To increase your brand quota, Free Trial and Starter users can upgrade to a Professional plan, while Professional users can upgrade to the Teams plan. If you do not choose to upgrade or you’re already a Teams subscriber, you can edit a current brand or delete and replace it.
