Your first invoice can sometimes be confusing.  One40 is a pre-paid service.  You paid for the first month of service in advance, on the date you signed up. However, if you added any additional numbers to your account, those charges have not been paid.  Now, 30 days later, it is time to pay for your next month of service.  This first invoice will reflect to you the charges for your first month of service, the payment that you already made to offset those charges, and your next month service charges.  If you had  added any add-on numbers, those charges will also appear on this invoice.  

For a detailed breakdown of charges, please email us at support@one40.com.
