How do I upgrade, downgrade or cancel my subscription plan?

Make sure you are logged into BigMarker. Then from your home page, choose the 'Billing' tab on the left side of the webpage. You need Admin privileges to access a channel's billing plan. 

From your Home Page:

In your Billing Section you can request to cancel your plan or downgrade it to another plan. You must email support to cancel or delete a channel or plan before or on your payment due date.
