SLA (Service Level Agreement)

An SLA is a formal commitment to a specific standard of service — commonly a response time or resolution time — that a vendor guarantees to a customer, often with consequences if the standard isn't met. In customer support specifically, SLAs typically define how quickly a ticket must receive a first response or be resolved.

Whether a support tool fits an organization often comes down to whether it's built around formal SLA structures or a more flexible, conversational workflow — this is the core distinction our review draws between Zendesk AI's SLA-native approach and Intercom Fin's more messaging-first design philosophy.

Discussed directly in our Zendesk AI review as its defining structural characteristic, in contrast to Intercom Fin's different approach.
