Support has been very good. Any time there has been a real issue, the team has responded very quickly and identified the issue without a lot of repetitive questions that I've seen from other services. There is a great external community and internal knowledge base that covers pretty much anything you need.
Built on the Now Platform, ServiceNow offers their Customer Service Management solution through the Standard and Professional Customer Service Management bundles. Both include agent workspace, knowledge management, survey and assessment module, and the community module, oriented in this edition to support customers rather than internal employees. The Professional bundle also includes performance analytics, predictive intelligence, and related tools to support customer support agents improvement as well. ServiceNow Field Service Management is available as an add-on via a separate license, and it allows users to connect field service with other teams and mobile tools to quickly respond to and prevent issues.
