Service Level Agreements (SLAs) are not merely contractual agreements; they are the backbone of effective service delivery and customer satisfaction. To achieve optimal outcomes and drive excellence in service delivery, organizations need to embrace best practices when crafting and implementing SLAs.

In this post, we unveil 9 essential service level agreement best practices to elevate your SLAs to new heights of excellence.

Although dealing with service level agreements (SLAs) might seem tedious, they are incredibly important for resolving problems between service providers and customers. These agreements not only streamline conflict resolution but also take a proactive approach to averting disputes by setting clear accountability for both parties. They serve as a crucial tool in enhancing customer service and effectively tracking key performance indicators, ensuring a smooth and accountable service delivery process.

Service level agreement (SLA) simply refers to the agreement between a service provider and its customers in which the service provider ensures to deliver a certain quality of service to its customers. 

Let's look at an example of a Service Level Agreement (SLA) from Slack. In this SLA, Slack guarantees that customers who subscribe to business and higher-tier plans will experience uptime of no less than 99.99%.

This means that customers can expect the service to be available and functioning at least 99.99% of the time, ensuring a highly reliable experience. The affected customers can raise the issue if they fail to ensure their commitment or manage customer expectations. In return, Slack will have to provide a credit of 10 times for the downtime period.

To establish a critical service level management agreement, it's imperative to adhere to a set of service level agreement best practices. But first, let's delve into the intricacies of Service Level Agreements; let's take a closer look at the concept itself.

What Is An SLA & Why Do Organizations Need It?

Service Level Agreements (SLAs) play a pivotal role in the business world, serving as essential documents that define the expectations and responsibilities between service providers and their clients.

A Service Level Agreement (SLA) is a formal contract or agreement between a service provider and a customer. It outlines the specific terms, conditions, and performance expectations that both parties must adhere to concerning the services being provided. SLAs are commonly used in various industries, including IT, telecommunications, outsourcing, and more, to establish a clear understanding of service quality, response times, and support levels.

Simply, Customer-based SLAs act as a foundational agreement between the service provider and customers that is an essential element for building trust. Further, SLAs set a certain standard for service expectations and service level targets in customers' minds, and it becomes a critical factor for priority work in the case of multiple concurrent issues.

SLAs reduce the concerns, uncertainty, and risks associated with service. Additionally, service level agreements (SLAs) assure the outcome of expected service with IT spending by giving clarity about the resolution to the customers.

Further, IT teams also often create internal service level agreements (SLAs) within the organization to provide a certain standard of service, so it becomes imperative to align providers and internal service level agreements (SLAs) prior.

What Are The 3 Types of Service Level Agreements?

Service Level Agreements (SLAs), different types cater to various business goals and service models. Understanding these distinct categories is essential for organizations to choose the most suitable SLA for their specific requirements. Here, we'll explore the three primary types of SLAs:

1. Customer-Based SLA (C-SLA): A Customer-Based SLA, also known as a Customer-Oriented SLA, is tailored to meet the unique needs and expectations of a specific customer or group of customers.                                                                                      

Key Features

  • C-SLAs are highly personalized and may encompass service level objectives (SLOs), performance metrics, and terms negotiated with individual customers.

  • They are particularly common in industries where services are customized or highly specialized, such as premium support services or enterprise-level solutions.


  • Improved customer satisfaction as services are aligned with customer preferences.

  • Flexibility to address unique customer requirements.


  • Managing multiple C-SLAs for different customers can be complex and resource-intensive.

2. Service-Based SLA (S-SLA): Service-based SLAs are structured around specific services or service categories rather than individual customers. They are often used by service providers offering standardized services to multiple clients.

Key Features

  • S-SLAs define service levels, performance targets, and responsibilities for a particular service offering.

  • These SLAs are often used when multiple customers are served using the same set of services, such as cloud computing or web hosting.


  • Simplified management as the same SLA applies to multiple customers using the same service.

  • Greater consistency in service quality.


  • May not address the specific needs of individual customers as comprehensively as C-SLAs.

3. Multi-Level SLA (ML-SLA): Multi-Level SLAs are a hierarchical arrangement of SLAs, where a primary SLA (often a Service-Based SLA) may have one or more secondary SLAs nested within it. The primary SLA outlines general service terms, while secondary SLAs define additional commitments or constraints.

Key Features

  • ML-SLAs are used when there's a need to provide differentiated service levels to customers or user groups.

  • The primary SLA sets the baseline standards, and secondary SLAs can specify variations for different customer tiers or service plans.


  • Allows for tiered service offerings, accommodating both standard and premium customers.

  • Provides flexibility in managing service levels based on customer segments.


  • Complexity in managing and monitoring multiple SLA layers.

The three primary types of SLAs—Customer-Based SLAs, Service-Based SLAs, and Multi-Level SLAs—each serve distinct purposes in aligning service expectations, ensuring accountability, and meeting the diverse needs of organizations and their customers. 

Choosing the appropriate type of SLA depends on the nature of the services provided and the specific requirements of the customer base.

Key Components of a Service Level Agreement (SLA)

In crafting a robust Service Level Agreement (SLA), understanding its fundamental components is paramount. So, let's explore these critical components and the pivotal role they play in ensuring seamless service delivery and customer satisfaction.

  • Service Description: An SLA defines the services or products being provided. It should offer a clear and concise description of what the customer can expect, including details about service availability and any specific resolution time commitments.

  • Service Level Objectives (SLOs): SLOs outline the specific performance targets, such as response times, uptime percentages, and resolution times, that the service provider commits to achieving. These objectives are critical in determining the quality and availability of the services provided.

  • Responsibilities: SLAs typically outline the responsibilities of both the service provider and the customer. This includes who is responsible for what tasks, reporting procedures, and escalation processes, all of which can directly impact resolution times and service availability.

  • Metrics and Measurement: To ensure accountability, SLAs often include detailed metrics and measurement methods that will be used to evaluate service performance. These metrics can encompass service availability percentages and the timeframes within which resolution time commitments must be met.

  • Penalties and Remedies: Consequences for failing to meet agreed-upon service levels are detailed in the SLA. This can include financial penalties or other remedies to compensate the customer for service disruptions, emphasizing the importance of adhering to both resolution time and service availability commitments.

SLAs play a crucial role in risk management by specifying responsibilities and consequences for any breaches. They shield against potential service disruptions or failures, minimizing associated risks.

For organizations, SLAs bring many benefits—enhanced communication, quality assurance, risk reduction, performance monitoring, and heightened customer satisfaction. Consequently, integrating SLAs strategically can significantly bolster an organization's overall success.

In this post, we will discuss some service level agreement best practices that IT teams should follow in negotiating with vendors and keeping track of service level agreements (SLAs).

9 Service Level Agreement Best Practices To Follow

Clarity and specificity are essential for any service level agreement (SLA). When reviewing SLAs, it's crucial to seek detailed terms.

For instance, instead of a vague commitment to resolve issues promptly, request a specific timeframe–whether it's within 24 hours, 48 hours, or another defined period. Similarly, you can follow several steps to ensure your SLA is strong and effective. So, let's explore some of the service-level agreement best practices when crafting effective SLAs.

1. Always Read All The Mentioned Terms 

Service level agreements (SLAs) are monotonous, and it may be frustrating to read all the terms and conditions mentioned. But, signing it without understanding every detail may cause a huge loss and damage to your organization.

Or, in some cases, you may miss out on any sort of compensation for any damage caused by the application if you don't follow the terms. So, the most important thing is to carefully read and understand every term and condition mentioned in the service level agreements (SLAs). Also, you can take the help of your finance, legal, and other relevant departments if any terms are associated with them.

2. Keep Different SLAs For Different Services

Every service is different, and they are associated with a unique set of problems. In some services, resolving a certain problem can be done quickly, while in others, it may take even a day or a few weeks as each IT service has its own lead time and approval schedule. 

So, if you take more than one service from a particular vendor, always maintain different service level agreements for every service. In this way, you will understand relevant details more clearly related to the different services.

3. Keep Service Level Agreements (SLAs) Specific

The different points mentioned in service-level agreements should be clear and specific; otherwise, you will get confused. A simple example can be rather than mentioning that all the issues will be resolved as soon as possible, you should look for a finite timeline for it and ask the vendor to change accordingly. 

A better way to write this can be that all the issues will be resolved within 24 hours or 48 hours (or any finite timeline based on the type of the issue). This way, you will have a clear understanding and idea of the maximum waiting period for any issue.

4. Set A Realistic Target

Thoroughly understand your current and future business needs and, based on that, define key metrics. You need to set targets for minimum and maximum requirements for each metric. For example, if your business does huge transactions online and the minimum uptime requirement is 99.999% in 24 hours.

So, go for 99.999% and more uptime. Further, depending on the requirements, the cost of service may vary. Hence, it's imperative that you should accurately evaluate requirements and check whether the pricing is reasonable and fits your budget or not. Set simple targets without merging multiple factors to make a complex one.

5. Track SLA Performance

You should not rely on the vendor to provide reports on the service level agreements (SLAs) performance but also measure the performance from your end too. In this way, both parties will have a sound understanding as well as a source of truth for relevant metrics.

Measuring performance not only helps you to know whether the providers are providing you the quality of service that they promised. But, it also helps you to understand the scope of improvement as well as make the provider accountable with relevant data in case of any service lag. Further, you can claim compensation which is listed for different service failures in the service level agreements (SLAs).

6. Align Every Stakeholder

Establish Consistency in Service Level Agreement (SLA) Goals and Anticipations Across Business, IT, and Strategic Partners to Cultivate a Shared Understanding. Avoid making commitments that exceed your internal SLAs if they are not synchronized with those of your service providers.

If you do so, you will fail to deliver the service that you promise, and in this way, it will affect your business relationship with the affected stakeholders. So, always ensure that you align internal service level agreements (SLAs) as per your providers for smooth functioning.

7. Review & Ask For Changes/Modifications

Change is unavoidable, and with time, as your requirements vary, you should reach out to service providers for the amendment in service level agreements (SLAs). In this way, you ensure that the service level agreement (range of services) meets your requirements and fulfills your designed business objectives at every point.

You cannot expect a provider to change the service quality with time when your requirements vary without communicating them. Also, if the provider makes any service changes, ask them to make relevant changes in the service-user level agreement.

8. Don't Be In A Hurry

Achieving designed outcomes for business from SLAs and service integrations takes time, and it requires continuous improvement. IT teams should understand the amount spent relative to the benefit or outcome they get from the service.

The understanding of value realization from SLAs is critical to establishing ongoing competence. IT teams can track the application's utility using Zluri to determine whether it is used fully or not. Applications that are duplicated or not used can be discarded to save costs.

9. Incentivize Vendor To Strive For Consistent Improvement

You should create incentives and mechanisms that encourage the vendor to continuously enhance their services over time. Employ SLA targets that demand ongoing enhancement throughout the agreement period, aligning your common type of business objectives with the provider's performance. This approach not only sets concrete goals but also acts as a catalyst for the vendor to consistently elevate efficiency.

By incorporating these service level agreement best practices into your agreements, you not only meet immediate customer service expectations but also gauge the provider's potential to fulfill evolving client expectations based on their progressive improvement.
