The user can choose for what period (by default to the end of the current month and for a maximum of 6 months) he wants to buy the plan.

                10. The billing period is the calendar month. If the User makes a payment to a prepaid account on a day other than the first day of a given month, User is required to pay the full monthly fee, as the number of queries available under a given plan may be used up in a single day.

                18. If the period of delay in payment exceeds 10 days from the due date, the Service Administrator is entitled to block the User’s Account until the amount due is settled.
                19.
