Service-level agreement

Service-level agreement

For B2B teams, understanding service-level agreements (SLAs) is essential because they establish the standards used to measure service performance and customer satisfaction.

What is an SLA, and why is it important for B2B companies?

Put simply, an SLA is a contract that outlines the performance standards a service provider commits to meeting.

In B2B support and SaaS environments, SLAs enforce accountability by defining measurable expectations for service quality. They typically include key metrics like service availability, response time, and resolution time.

The primary benefit of SLAs is clarity. It gives both the service provider and the client a way to objectively measure whether the service is meeting customer expectations. Instead of relying on subjective opinions, teams can compare actual performance against the criteria outlined in the agreement.

According to Front’s State of Service Expectations report, one-third of customers expect a response within two hours or less. If this performance standard is included in an SLA, you can track it. For example, replying within the specified time frame 95% of the time translates to 95% SLA compliance, which is hard data that no one can dispute.

Types of service-level agreements

You can structure SLAs in several different ways depending on your needs. Here are the most common types of agreements:

  • Customer-level SLAs are contracts between a service provider and a customer. The customer may be external to the service provider or internal, such as another department within the same organization. The advantage of this type of SLA is that you can tailor it to each client’s exact needs.
  • Service-level SLAs define blanket performance standards for anyone using the service. They function like a universal SLA template: Write it once, and use it everywhere.
  • Multi-level SLAs are more complex, but also more customizable. They’re split into multiple layers to define commitments for different service tiers or parties within the same contract.

The key components of SLAs

Learning how to manage SLAs starts with knowing what goes into them. SLAs contain three high-level elements: the service quality metrics tracked, the performance standards for those metrics, and the consequences of missing those targets.

Common subcomponents of these elements include:

  • Key performance indicators (KPIs): These are the specific, agreed-upon metrics for measuring service quality, such as response and resolution times. SLA software often uses automation to keep track of critical KPIs.
  • Remedies: SLAs typically outline the penalties, escalation steps, or refunds for unmet contractual obligations on either side.
  • Contract termination clauses: These rules specify the conditions when a customer has the right to terminate the contract due to poor performance. For example, a client may be allowed to cancel the contract if multiple Priority 1 issues go unresolved within a specified time frame.
  • Exclusions: Exclusions list aspects of the service that are not subject to the terms of the contract, such as scheduled maintenance.
  • Adjustment process: Customer needs and service provider capabilities may change over time, which means some flexibility needs to be baked into the SLA. Review and adjustment clauses note how and when parties can adjust the SLA to update KPIs or performance targets.
