Service SLA - Service Level Agreement

11.06.2026

To enhance competitiveness and customer trust, companies operating in the service sector are recommended to use an SLA (service level agreement). This is an appendix to the cooperation agreement, signed by both parties. It clearly outlines the speed and quality of services provided. While a standard agreement specifies the list of services, prices, and deadlines, the appendix specifies measurable quality parameters in figures, such as how many hours it will take to complete the obligations and what liability will arise for missed deadlines.

Advantages of SLA in Customer Service

An SLA in customer service is an important tool for managing service quality. It helps maintain high standards and organize effective interactions between the contractor and the client. Its benefits include:

  • clarity of expectations;
  • improved service quality;
  • establishing trust between partners;
  • minimizing risks associated with the quality and availability of services.

An SLA sets clear parameters that manage the expectations and obligations of the parties, resulting in higher levels of customer satisfaction and business success.

What does an SLA include?

An SLA establishes the parties' commitments to achieving certain standards of quality, availability, and response time. It includes:

  • a detailed description of the services provided, including functional characteristics and delivery features;
  • definition of metrics that will be used to determine the service level and assess the quality of services provided;
  • responsibilities and rights of the parties;
  • methods for monitoring SLA compliance and reporting frequency;
  • penalties and compensation that will be applied in the event of non-fulfillment of the SLA terms;
  • indication of the validity period and review conditions.

Signing a service level agreement is necessary to protect the interests of the parties, therefore, special requirements are imposed on its drafting. These include, first and foremost, the specificity of standards—expressing each indicator in numbers (days, hours, etc.)—and avoiding arbitrary interpretations. Deadlines for fulfilling obligations must be realistic and without compromising quality. The procedure for recording violations, the calculation of penalties tied to a specific event, and a list of exceptions (specific force majeure) are also specified.
