Your IT provider replies in ten minutes. Three hours later, though, your employees still cannot access the system they need to work. The response was fast, but you are probably not feeling especially well supported.
That is why IT support SLAs deserve more attention than a promised callback time. Response and resolution measure different things. Understanding both helps you ask a better question: what happens between someone answering your ticket and your team getting back to work?
What Should IT Support SLAs Cover?
An SLA, or service level agreement, sets expectations between you and your provider. It explains which services are included, how performance is measured, and what happens when commitments are missed. An average describes past performance; an SLA sets a commitment.
For support requests, two measures matter:
- Response time: How long it takes to provide the agreed first response after an issue is reported.
- Resolution time: How long it takes to resolve the issue after it is logged, subject to the agreement’s timing rules.
IT support SLAs should define both, along with support hours, priorities, and escalation procedures. Otherwise, two providers promising the same number could be offering very different support.

SLA Response Time: A Reply Is Only the Start
SLA response time measures the wait for an initial response. In Freshservice, for example, first-response reporting measures when an agent first replies to the requester. That alone does not tell you whether troubleshooting has begun.
For perspective, Freshworks’ 2025 benchmark summary reports an average first response time of 9.36 hours for IT teams deploying AI. This is a study-specific benchmark, not a universal average across managed IT providers or a recommended wait during an outage.
And beating that average is not the whole goal. A quick “we’re looking into it” message is reassuring, but what happens next? When reviewing IT support SLAs, ask what stops the response clock and how quickly someone qualified begins addressing the problem.
SLA Resolution Time: When Can You Work Again?
SLA resolution time concerns the time allowed to resolve an issue. It is not necessarily an additional period that starts after the first response.
Suppose you submit a ticket at 9 a.m., receive a reply at 9:10, and the issue is resolved at 1 p.m. With no pauses or excluded hours, that is a ten-minute response and a four-hour resolution.
The same Freshworks benchmark summary reports an average resolution time of 21.96 hours. Again, that is a reference point from its study, not a target every business should accept.
When reviewing IT support SLAs, ask what counts as “resolved.” Does it mean your staff can work again, and who follows up if the problem returns?
Why IT Support SLAs Can Look Better on Paper
A provider advertising an average resolution time under four hours might deliver excellent support. But that number needs context.
Consider a hypothetical example: nine tickets take 20 minutes each, while one takes 20 hours. The average is just two hours and 18 minutes. That sounds impressive, unless yours was the outage that lasted 20 hours.
Reporting rules can also change the picture:
- Paused clocks: Atlassian documents that SLA timers can pause while waiting for a customer. That time may disappear from the SLA measurement, but not from your actual wait.
- Business hours only: An SLA calendar can exclude evenings, weekends, and holidays. Four measured hours could therefore stretch into the next business day.
- First resolution only: Zendesk distinguishes first resolution from the most recent resolution. Reporting only the first can leave out the extra wait after a ticket is reopened.
These rules are not automatically dishonest. The concern is presenting a limited measurement as the complete experience, or marking something resolved before it actually is.
Ask for elapsed time, reopened tickets, and performance by priority alongside IT support SLAs. You need to know how critical problems are handled, not just how quickly the easy ones get closed.
Measure Support by the Work You Get Back
Fast responses matter, but IT support SLAs should help you evaluate more than how quickly someone answers. Look for meaningful action, restored operations, and follow-through on recurring problems.
At Kirkham IronTech, our view is simple: we don’t only manage tickets. We manage business impact. If your provider’s numbers look great but your team keeps losing time, it is worth asking what those numbers actually measure.
