Service Level Agreement (SLA) Templates: Examples, Metrics, and Best Practices

How quickly should your team resolve a critical ticket, and what are the consequences when it misses the target?

That is exactly where Service Level Agreements (SLAs) come into play. An SLA turns service expectations into measurable commitments by defining clear response and resolution targets.

Rather than starting from scratch, an SLA template provides a structured foundation for establishing those commitments and tracking performance against agreed standards.

Why does that matter? Because failing to meet service targets can lead to downtime, and downtime can be costly.

According to ITIC's 2024 Hourly Cost of Downtime Survey, more than 90% of enterprises estimate the cost of a single hour of downtime at over $300,000. The financial impact alone highlights why clearly defined service expectations are critical.

In this guide, you'll find ready-to-use SLA templates ranging from simple agreements to detailed enterprise-level frameworks.

You'll also learn how to build SLA matrices, define key performance metrics, and apply practical examples to create effective and measurable service commitments.

What is a Service Level Agreement (SLA)?

An SLA, or service level agreement, is a contract between a service provider and a customer that sets out the level of service the provider commits to, and the remedy when it falls short.

The two sides can be anything from separate companies to two teams working for the same company.

A good SLA is specific where it matters the most. Instead of promising fast support. It promises a response in 15 minutes and a fix in 4 hours, for a named priority, measured against the clock.

That precision is the whole job. It gives the customer a number to expect and gives both sides the same number to argue from when something slips. Vague SLAs help no one and create unnecessary confusion.

SLA vs SLO vs SLI

Three terms can easily get mixed up and keeping them straight makes your SLA stronger. Let’s take a look at the definition and the key differences between these three terms:

1. An SLA is the promise you make to the customer.

2. An SLO, or service level objective, is the stricter target you hold your own team to.

3. An SLI, or service level indicator, is the number you actually measure.

Keep the SLO stricter than the SLA, and that gap becomes your safety buffer.

When the gap between SLI and SLO starts reducing, you have time to act before the customer promise is at risk.

What are the Main Types of SLA?

Most agreements fall under one of these 3 types of SLAs. Pick the one that matches who is on the other side.

1. Customer-based SLA

One customer, every service you give them, in a single contract. It keeps life simple for the vendor, because everything sits in one place. A voice provider folding all its voice services for one client into one agreement is the classic case.

2. Service-based SLA

One service, every customer who uses it, on identical terms. The standard does not move from client to client, so it stays clean. The agreement that sets how your help desk handles tickets applies to everyone on that service.

3. Multi-level SLA

Several layers are stacked into one agreement, so you stop repeating yourself. A common split runs corporate (terms for the whole organization), customer (terms for one group), and service (terms for one service that group uses).

What Should Every SLA Template Include?

Whatever shape you pick, the bones are the same. Each section below exists to kill a question before it turns into a dispute six months in.

• Agreement overview: the parties, the dates, and the purpose.

• Service scope: what is covered, and the part people forget, what is not.

• Service level targets: the measurable promises, like availability, response time, and resolution time.

• Roles and responsibilities: what you own, and what the customer has to do to keep the agreement valid.

• Escalation path: who gets pulled in, and when, as an issue climbs.

• Exceptions: when the clock pauses, such as scheduled maintenance or events outside your control.

• Service credits and remedies: what the customer gets when you miss.

• Reporting and review: how performance is reported, and how often both sides sit down over it.

• Approvals: version history, signatures, and a short glossary for any term open to interpretation.

Listing the parts is easy. Setting targets that you can actually hit is the hard part, and our guide to set and measure SLA targets walks through picking numbers you can defend later.

Download a Simple SLA Template

When the agreement covers a single service and needs to fit on two pages, this is the one to reach for. It carries every part covered above, with nothing extra to slow you down. Grab the Word file, fill in the brackets, and you have a working draft.

What it covers:

• Parties, effective date, and review date

• Service description and what falls out of scope

• Service hours

• Service level targets, including the priority matrix for response and resolution times

• Responsibilities for each side, and the escalation path

• Service credits for a missed target

• Review cadence, approvals, and signatures

How to use it:

1. Open the file in Word or Google Docs and save your own copy.

2. Replace every field in square brackets with your own details.

3. Set your priority tiers, and a response and resolution time for each, using numbers your team can actually hit.

4. Add your service credits and the review cadence.

5. Have a qualified legal or contracts professional review it before you sign it or send it to a customer.

When the agreement covers several services, or the stakes justify spelling everything out, you want the longer version. It is the same structure as the simple template, expanded into numbered sections with room for pricing, a glossary, and governance.

What it covers:

• Section 1, Overview: parties, purpose, glossary, and contract duration

• Section 2, Service Scope: services covered, exclusions, hours, and deliverables

• Section 3, Service Levels: availability target, priority definitions, and the response and resolution matrix

• Section 4, Responsibilities: provider and customer duties

• Section 5, Performance and Remedies: how performance is measured, service credits, and breach handling

• Section 6, Governance: review cadence, change process, and approvals

• Appendix: pricing, service tiers, and reference documents

How to use it:

1. Open the file in Word or Google Docs and save your own copy.

2. Work through it section by section, replacing the bracketed fields as you go.

3. Fill in the priority matrix in Section 3 with your real response and resolution targets.

4. Complete the service credits and the monthly cap in Section 5, and the pricing in the appendix if it applies.

5. Send it to your legal or contracts team for review before it reaches a customer.

SLA Templates by Use Case

The structure holds across teams. What moves is the targets, the language, and the sections you lean on. Here is what to change for the cases people search for most.

1. IT service desk SLA template

Lead with the priority matrix, because an IT service desk or help desk is judged on response and resolution times by priority.

Define priority by business impact, not by what is technically broken: a down payroll run is Critical, one user's stuck printer is Low.

Then commit only to times your technicians can hit during staffed hours.

2. ITIL SLA template

If your team runs on ITIL 4, map the agreement to the service level management practice.

Add an OLA underneath for the internal teams that prop up the service. And make sure the SLA never promises more than those underpinning agreements can deliver.

3. MSP SLA template

A managed service provider juggles many clients, so the multi-level shape fits. Keep one corporate baseline, then layer per-client terms on top.

Be exact about service credits and the monthly cap, because that is the first section a client reads, and the one they quote back to you.

4. Internal SLA and OLA template

Between two internal teams the language loosens, but the targets still bite.

This is usually an operational level agreement rather than a customer SLA, and the difference between SLAs and OLAs is worth pinning down

That way, you can make sure that the promises you make outward can be backed by realistic ones inward.

5. SaaS and website SLA template

For a SaaS product or a hosted site, uptime is the headline number.

State the monthly availability target, put the downtime it allows right beneath it so nobody can misread the math, and list your maintenance windows as planned exceptions.

Then add the credit schedule that kicks in when you drop below the promise.

SLA Matrix: Priority, Response, and Resolution Times

The most useful table in any SLA is the priority matrix. It settles the argument about how fast is fast enough by writing it down, in advance, where both sides can see it.

Set your own numbers from what your team can deliver, not from what reads well in a pitch.

What are Some Common SLA Metrics to Track?

A target you do not measure is just a wish. These are the numbers that show whether you are keeping the agreement, and they belong in the monthly report.

• Response time: how long before a technician picks up the ticket.

• Resolution time: how long before it is fixed. This rolls up into your mean time to resolution, the average across every ticket.

• First contact resolution: the share closed without a second touch.

• Availability or uptime: the percentage of time the service is actually up.

• SLA compliance rate: the share of tickets that hit their target.

• Abandonment rate: the share of requests that died inside the response window.

Here’s a simple tracking table to help you keep the report accurate:

Real-World SLA Examples

You do not have to picture a live SLA, because the biggest providers and plenty of public institutions publish theirs in full.

Reading a few real ones is the fastest way to see how the parts above come together. Here are five worth studying, and what each does well.

• AWS Service Level Agreements: AWS publishes a separate SLA for each service, with its compute SLA committing to 99.99 percent monthly uptime and paying service credits when it misses. A clear model for tiered, per-service commitments.

• Google Cloud SLAs: one hub linking every product SLA, with Cloud Storage set at 99.95 percent monthly uptime. It’s a useful example for seeing how a provider keeps dozens of SLAs consistent.

• Microsoft Azure SLAs: Azure states its uptime and connectivity commitments per service, most landing between 99.9 and 99.99 percent. It’s a solid service level agreement example as reference for availability tiers.

• DNSimple Service Level Agreement: a short, readable SLA that spells out what counts as an outage, what does not, and the remediation credits that follow. Proof that an SLA does not have to be long to be effective.

• University of Saskatchewan IT Core Services SLA: a public-sector SLA that defines service levels for faculty, staff, and students. A strong reference if you are writing an internal IT service desk SLA.

You can borrow the structure from any one of these that best suits your scenario, then set your own numbers.

The number hiding behind every uptime promise is downtime, and the two are easy to mix up.

This table shows a few examples of the uptime levels we typically aim for:

The jump from 99.9 to 99.99 percent looks tiny on the page. In the real world it is the gap between roughly nine hours of downtime a year and under one.

To keep the cost of closing it from climbing fast, promise the level you can fund, not the one that wins the meeting.

What are SLA Best Practices That You Should Follow?

A template gives you a jumpstart, but a few habits decide whether the agreement survives a bad month or not.

Here are the best practices when drafting a service level agreement.

• Set targets from your own trailing data, not a competitor's marketing.

• Tie every target to a metric you already track, so the SLA reports itself.

• Keep your internal target stricter than the customer promise, to leave yourself a buffer.

• Define priority by business impact, not technical cause.

• Put response and resolution in a matrix, so nothing is left to a judgment call at 2 a.m.

• Review the agreement every quarter, and move the numbers as the data comes in.

• Automate tracking and escalation, because manual SLA monitoring is the first thing to break at volume.

Downtime is expensive; an Oxford Economics study describes the average near 9,000 dollars a minute, so the targets in your SLA are not paperwork. They are money.

Here is the mistake almost everyone makes. They start from a generic contract and fill in round, impressive numbers, because the template invited them to. Start the other way.

Begin from what you can measure and enforce, because an SLA you cannot measure is worse than none: it sets an expectation you will quietly break, and the customer will notice before you do.

Put Your SLA Template to Work Now

Going with the strictest numbers won’t necessarily result in the best SLA template.

Instead, your team should be able to measure and meet those targets on every ticket, because a kept promise builds more trust than an ambitious one that you fail to deliver on.

A template cannot set realistic targets for you. An SLA built on numbers you cannot meet will cost you more credibility than no SLA at all, so the work of choosing targets you can defend stays yours.

Start with one service, one priority matrix, and targets pulled from last quarter's data, and you will have an agreement that holds under pressure.

The next step is making it run without anyone watching the clock, and if you want to see SLAs enforced automatically against your real ticket volume, you can start a free ServiceOps trial and test it on a single workflow.
