Each domain has specified expiration date, ie. the day of its expiry. If you want to continue using the domain, it needs in extend the expiration date.
If you do not renew domain, depending on the particular TLD it will be shut down and later also to the complete cancellation.
If it is not set otherwise, our system for all domains 30 days before their expiration creates automatically renewal order and sens it to the customer by email.
This behavior before expiration can be modified, see Setting expiration and renewal of services.
