Service Level Agreement (SLA): These are the 6 key components
A Service Level Agreement (SLA) is an agreement in which the contracting parties define the scope of expected services, quality standards and responsibilities. SLAs are typical components of service contracts, especially in the IT sector. We explain the key aspects of Service Level Agreements and highlight their importance to businesses.
What is a Service Level Agreement (SLA)?
An SLA is a part of a contract that details the services that a supplier will provide to its customers, and in particular the measurable standards that should apply to those services. SLAs are used in different industries and for different services, from IT to logistics. SLAs are regularly included in contracts for Software-as-a-Service products (SaaS contracts).
An SLA is often and regularly agreed when the statutory warranty provisions are inadequate or inappropriate. Particularly in the case of Software-as-a-Service products, where prompt support and rapid troubleshooting are important, it is important to agree specific provisions on rights and obligations in the event of problems and service interruptions.
Why are SLAs important in SaaS contracts?
SLAs play a particularly important role in SaaS contracts. SaaS products are regularly used for important or even critical business processes. In addition, customers usually pay a monthly fee for the product.
Therefore, it is important to agree on the quality standards of the product, when support will be available and within what timeframe errors will be corrected. An SLA therefore makes it possible to measure the quality of the service, particularly in the case of SaaS contracts. The parties to the contract gain certainty as to whether and to what extent the SaaS product meets the agreed standards, i.e. when there is an 'error' or 'defect'.
As a result, customers can estimate whether or how much they will have to pay for the service despite the failure to meet the agreed standards.
An SLA provides clear guidelines and specifications to give the contracting parties an overview of the service content, as well as the specific rights and obligations, and to assess the risk of failures (or similar) in advance.

What are the key components of a Service Level Agreement (SLA)?
The components and content of an SLA are highly dependent on the industry and the specific type of service to which the SLA applies. However, the following aspects should typically be part of an SLA, or at least part of the contract if they are not formally part of the SLA:
#1 Service Description
The services to be provided should be described clearly and in detail. This includes the nature of the service, the provider's responsibilities and the customer's expectations.
In addition, if not already included as a separate section in the SLA, there should be a description and definition of service interruption, i.e. a description of the circumstances in which the service owed is not (or is no longer) provided in accordance with the contract, and what the customer's rights are in such cases.
#2 Key Performance Indicators
These key performance indicators measure the quality and efficiency of the services provided. Examples include response times, availability and error rates. The key performance indicators provide the organisation with a quick overview of the most relevant information about the service, enabling it to measure and verify the performance owed.
#3 Availability guarantees
SLAs often specify how often and for how long a service must be available. In this context, the SLA should also include information about maintenance work and times (frequency, duration and timing). This availability is particularly important for IT services, where downtime can have a significant impact on the business.
For example, in the case of Software-as-a-Service products, the availability of the product for the entire service period is typically not agreed (this is not possible for technical reasons). For example, if 99% availability is agreed, the provider will have fulfilled 100% of its performance obligation if it meets that level.
If the product is unavailable for 1% of the service period, the provider is not liable for the 1% of the agreed availability period if no other obligations have been breached. The clear regulation of availability is therefore also relevant to issues of liability and warranty.
#4 Response times
Response time information is also closely related to the service availability provisions. This refers to the time taken by the service provider to respond to requests or problems.
This is not only crucial for customer satisfaction, but can also have an impact on the business, especially in the case of IT services. This is because timely solutions are usually desirable in order to resolve and prevent long-term or significant outages or application problems.
#5 Reporting and verification
To enable the business to continually monitor the performance owed, the SLA should include regular reports on the service provider's performance and compliance with the SLA. This not only ensures transparency, but also enables the parties to identify potential problems early and work out appropriate solutions.
#6 Penalties and incentives
SLAs should also contain provisions that define the consequences of failing to meet agreed standards. These can include financial penalties (contractual penalties), but service credits are also common. In serious cases, there may also be a right of termination.
On the other hand, the provider may be incentivised (e.g. by the prospect of bonus payments) to exceed its obligations.

The importance of SLAs for companies
The primary purpose of an SLA is to provide the contracting parties with factual and legal clarity about the service to be provided and the associated rights and obligations.
Clarity and transparency
SLAs create a clear basis for expectations between service providers and customers. This reduces misunderstandings and conflicts from the outset, and makes it easier to resolve disputes by specifying rights and obligations.
Improved service quality
By defining performance standards, service providers are motivated to meet the requirements of their services in accordance with the SLA and to continuously improve them. For the business, this enables continuous and cursory monitoring of service compliance at any time.
Risk Management
SLAs help organisations identify and manage potential risks by setting clear guidelines and expectations for dealing with problems and failures. For example, when submitting a support request to the provider, the organisation can estimate when and how long to expect a response and resolution based on the specifications in the SLA.
Customer Satisfaction
A well-written SLA contributes to customer satisfaction by ensuring that services meet expectations and problems are resolved quickly.
Our conclusion about the service level agreement
Service Level Agreements are an integral part of well-drafted (IT) contracts and a critical tool for organisations delivering services in an increasingly complex and competitive environment. They promote clarity, transparency and quality in service delivery and help to strengthen the relationship between service providers and customers.
Organisations should therefore ensure that they develop and regularly review well-designed SLAs to meet changing requirements and expectations. A concrete SLA is not only an indispensable prerequisite for the successful integration of the relevant service, but also serves to provide legal certainty for the contracting parties.
To achieve this, early consultation is essential. This is because, depending on the service and industry, it is not only the relevant specialist legislation that needs to be observed. The SLA must also comply with general contract law (e.g. review of general terms and conditions).
