The duration of a subscription is typically one year, beginning 10 days from the provisioning date. Service suspensions or multi-year subscriptions will affect the renewal date. Sixty days before a subscription expires, Campbell Scientific will send the customer contact a renewal notice via email with a link to the online renewal center on the Your Account page. From there, customers can renew the subscription and select a method of payment. Customers can renew their subscription at any time and can pay for up to five years of service.
