Service Level Agreement (SLA)
Definition
A Service Level Agreement (SLA) is a defined commitment to respond to or resolve support requests within a set time, often varying by priority, channel, or customer tier.
How it works
An SLA sets targets like "first response within 1 hour" and "resolution within 8 hours" for high-priority tickets, with looser targets for lower priorities. Most help desks let you configure SLA policies that start a timer when a ticket meets certain conditions, then flag or escalate it as the deadline approaches.
SLAs are usually measured against business hours, and the clock often pauses while a ticket is pending on the customer, so the target reflects agent-controllable time.
Why it matters
SLAs turn vague promises into measurable, accountable commitments — for both customers and internal teams. They shape prioritization, drive routing and escalation rules, and are frequently contractual for enterprise accounts. A missed target is an SLA breach, which is why fast first responses (a strength of AI agents) protect SLA compliance.
- First-response SLA — time to the first meaningful reply
- Resolution SLA — time until the issue is fully solved
- Tiered by priority, channel, or customer plan
Frequently asked
What is an SLA breach?
An SLA breach happens when a ticket misses its committed response or resolution target — for example, no first reply within the promised hour. Breaches are tracked to spot capacity and process problems.
What is the difference between an SLA and a service level?
A service level is the measured performance (e.g., percentage of tickets answered within target); an SLA is the agreed commitment to hit that level. The service level tells you whether the SLA is being met.
