      <h1>-> Paddle Setup</h1>
      <p>
        In order to use workspace.global <b>with paid features</b>, you need to setup a Paddle
        subscription. A Paddle connection is bound to an organization.
      </p>
      <p>
        The base price of a Paddle Subscription is always 0€. Any charges that occur will be billed
        as an extra charge on top of your free base subscription
        <b>on a monthly date of your choosing</b>.
      </p>
      <p>
        Since Paddle acts as merchant of record, your invoices will read Paddle as Creditor, and you
        as Debitor.
      </p>
      <h2>Why are we using Paddle?</h2>
      <p>
        Paddle takes care of tax compliance for us. This allows us to sell our products world wide
        while Paddle makes sure any sales are in compliance with local laws.
      </p>
