Why are I going to be charged for 2 subscriptions with one account

[Jason]

I am in a free trail premium and looking to subscribe to the premium account but it looks like I am going to be charged for two subscriptions and not sure why. I have one workspace with about 10 boards and my account is in someone else's guest workspaces this is so I can receive work from them and put into my boards. Would this be the reason ? or what could be another reason.

Subscriptions don't apply to an account. They apply to a workspace. In a workspace, you are billed per the number of seats needed. Every user who is added to more than one board in the workspace will need a seat.

So, if you are being billed for "two subscriptions", it sounds to me like one of two things may be happening:

1: You have two Premium workspaces, hence 2 subscriptions

2: You have one Premium workspace, but have noticed that the charge is for 2 seats. This would mean there are 2 billable users in your workspace.
