Pogoplug Business Backup costs $10 per month/$100 per year for the master account. Each invited user can be billed monthly or yearly, and each invited user costs $10 per month or $100 per year. Two charges will appear on your statement: one for the master account and one for all of the team members you invite at the time of sign-up. If you add additional team members at a later date, those team members will appear as separate chanrges on your card. Team members cannot be mixed and matched with yearly and monthly charges, so either all of your invited members can be annual or all of them can be monthly, but you cannot have a mix of both. For example, you could not invite two team members to be monthly and one team member to be yearly.
