Example 1: You're on a 1 Artist Plan ($20/month) and you'd like to upgrade to 2 Artists (+$10/month) or 3 Artists (+$20/month).
Go to the Artist Plan subscription page (https://app.chartmetric.com/plan/artist) and search for the artists you'd like to add. Complete the billing process and they will be added to your account.
Example 2: You're on a 2 Artist Plan ($30/month) and you'd like to upgrade to 3 Artists (+$10/month) or downgrade to 1 Artist (-$10/month).
For upgrading, the process is the same as in example 1 above. For downgrading, please contact [email protected] or send a message to the support chat located at the bottom right corner of any page.
