What to actually expect from your managed IT provider's SLA
Every managed IT proposal leads with the same word: uptime. The document that actually matters is the one that defines what that word means in hours, minutes, and consequences when it's missed.
An SLA is the one part of a support contract that converts intent into obligation. Everything else in a sales conversation is description; the SLA is what you can actually hold a provider to when something goes wrong.
Response time and resolution time are not the same promise
Response time measures how quickly someone acknowledges and starts working an issue. Resolution time measures how long the fix actually takes, from the moment it's raised to the moment normal service genuinely returns. A provider can meet every response target and still leave a business broken for days — fast acknowledgement is a sign of a well-run desk, but on its own it measures reception, not repair. Insist a "response" means contact from someone who has read the ticket and can begin diagnosis, not an automated message confirming receipt.
Priority tiers should be specific, not vague
A well-structured SLA defines targets by both impact and urgency, typically across four tiers: critical outages get a response within minutes and resolution within hours, while low-impact requests can reasonably wait longer. If your SLA doesn't distinguish priority levels at all, every request — from a password reset to a full outage — is effectively competing in the same queue.
The metrics that reveal how a provider actually performs
First-contact resolution rate shows how often problems get solved without a second interaction. Mean time to resolution tracks the full cycle from ticket creation to confirmed fix. Escalation rate reveals how often front-line staff have to hand a problem upward. SLA compliance tracks whether contractual targets are actually being hit, not just promised. Together these tell you more about day-to-day performance than an uptime percentage ever will on its own.
What good reporting looks like
Regular, plain reporting against these metrics — not just a headline uptime figure once a year — is what turns an SLA from a document into something you can actually manage the relationship against. If a provider can't show you response times, resolution times, and escalation patterns on request, there's no way to know whether the SLA is being met or just assumed.
Reading the fine print before you sign
Look for exactly how each measurement starts and stops, what counts as a priority-one incident, and what happens — concretely — when a target is missed. A vague SLA gives a provider room to define success in whatever way suits them after the fact.
