You have two billing options for your pCloud Business account, and generally for any pCloud account. Those are monthly and yearly subscription. If you pay for an annual subscription, you get 20% off of your payment amount. At any moment you can switch between annual and monthly subscription if you go to the Billing tab of the Account section of your business account. If you are currently using monthly subscription, click the Upgrade to Annual and Save 20% link. If you are using yearly subscription, do the opposite to switch to monthly subscription. Note that only business account owners and users who hold Account Management permissions can modify the billing plan.
