I understand that SLA has nothing to do with a contract other than expected turnaround times. Most our customers are on simple annual support contracts, so I was curious if the SLA system could be somehow used to indicate when a contract had 'expired'. Perhaps by adding an SLA for the customer when their contract is renewed, but expiring in one year. Would there be a reasonable way to see if they weren't on a 'contract' SLA vs the 'downgrade' SLA? Is there a better approach?
