If you are on the Business plan, you can have multiple stores under the same organization. You can quickly switch between your stores directly from the admin dashboard.
How it works
Go to your admin dashboard
Hover your mouse over your store name
You will see a section called "My stores"
Click on any store to switch
You can see up to 5 stores in this menu for quick access.
If you have more than 5 stores, click "See all stores"
