-:bookmark_tabs: *1 When an invoice is generated for a registrant managed domain name where the billing contact is a non-registrar, the domain names with expiration in a given calendar month are collected on a single invoice for the month as a whole. This mean that a given domain name can be marked for collection between 45 to 75 days prior to expiration. The 45 days are due to the constraints involving requirements for automatic payment via **Betalings Service** (BS) and since a domain name can have expiration by the end of the month, the length of the month has to be taken into account, extending the period with 30 days, giving a total of 75 days.

 Do note the constraints on when you can change the billing contact, since might limit window of opportunity for manual renewal and being the billing contact for the domain is a explicit requirement.
