Support Process

Once you have contacted CBIIT Application Support, a ticket is generated to track the issues and requests to ensure resolution and customer satisfaction. CBIIT Application Support will contact you within 48 hours.

Many support requests are handled directly by a CBIIT Application Support specialist, but when necessary, issues are triaged to the appropriate internal development teams. In these cases, the specialist still tracks the request to ensure your needs are met before a ticket is closed.
