Enterprise invoicing: billing period

We are in the process of implementing a new billing system which will align all subscriptions to start on the first of the month. Your first invoice on the new system will have a different billing period if you were previously billed for a period starting on a different date. If your start date or renewal date is up to 7 days before the end of the month you may have received an invoice for a reduced period up to the end of a month. Alternatively if your start date or renewal date is within 7 days of the end of the month you may have received an invoice for an extended period of the last days of one month followed by the usual term of one month, 3 months, 6 months or 12 months. This will be your initial invoice from this system and future invoices will be for the period of your subscription plan and always on the 1st of the month.
