The Types of SLAs Explained


Service Level Agreements (SLAs) are essential contracts that set expectations for service delivery between service providers and their customers. These agreements help ensure consistency, accountability, and transparency in business operations.

SLAs are often used in customer service, IT, and vendor relationships to define the level of service that customers can expect and the standards that service providers must meet.

SLAs are more than just legal contracts; they are vital to maintaining strong relationships with customers, streamlining internal processes, and ensuring that expectations are managed effectively. There are several types of SLAs, each tailored to specific needs within the business.

In this article, we’ll break down the three primary types of SLAs and explain why each one is crucial for the smooth operation of a business.


1. Customer Service SLAs

Customer Service SLAs are perhaps the most well-known and commonly used type of SLA. These agreements are between a business and its customers, defining the expectations for service delivery.

Typically, Customer Service SLAs specify how long it should take for a company to acknowledge a support ticket, how quickly issues should be resolved, and what level of service customers can expect in terms of quality and responsiveness.

Key Elements of Customer Service SLAs:

  • Response Times: How long it takes for the business to acknowledge a ticket or issue.
  • Resolution Times: The maximum time it takes to resolve the problem, typically based on its priority.
  • Escalation Procedures: Clear steps for how issues are escalated to higher levels of support if not resolved within the set time frame.
  • Support Hours: Defining the hours of support availability, whether it’s 24/7, business hours, or specific to regions.

For example, an SLA might state that a support ticket should be acknowledged within 24 hours, and any urgent issues should be resolved within 48 hours. These agreements often take into account different levels of urgency, with more critical issues being resolved faster than non-urgent queries.

For instance, if a customer is experiencing a technical issue that prevents them from accessing a product or service, the SLA might guarantee a resolution time of a few hours, while less critical problems could have a longer resolution window.

Customer Service SLAs also help to manage customer expectations. When customers know what they can expect in terms of service levels, they are less likely to feel frustrated or dissatisfied.

These agreements set a benchmark for the quality of service customers should receive, ensuring that the business meets its promises and delivers value.

Benefits of Customer Service SLAs:

  • Enhanced Customer Satisfaction: Customers are more likely to be satisfied when they know exactly when to expect a solution.
  • Clear Communication: SLAs set clear expectations on how issues are handled and what the customer should expect in terms of timeframes and quality.
  • Accountability: Both the business and customer know what’s expected, reducing the chances of misunderstanding.

2. Internal SLAs

While Customer Service SLAs focus on the relationship between businesses and their customers, Internal SLAs are agreements within the organization itself.

These agreements are usually between different departments or teams and ensure that internal operations are efficient, streamlined, and aligned with business goals.

Key Features of Internal SLAs:

  • Team Responsibilities: Clearly defining which department or team is responsible for specific tasks or requests.
  • Time Frames: Setting time-based targets for response and resolution, ensuring teams operate efficiently.
  • Communication Standards: Outlining how teams will communicate with each other, ensuring smooth collaboration.

For example, an IT department might have an SLA with the Customer Service team to resolve technical issues within a specified time frame.

If a customer support agent encounters a technical issue with the help desk software, the SLA between IT and Customer Service might state that the IT department must address and resolve the issue within 24 hours.

Internal SLAs ensure that each department meets its responsibilities in a timely manner, preventing bottlenecks and ensuring smooth coordination across the organization.

Benefits of Internal SLAs:

  • Streamlined Operations: Internal SLAs help eliminate delays between departments, ensuring that each team operates efficiently and meets its goals.
  • Enhanced Collaboration: By defining clear expectations and time frames, teams work together more effectively and reduce friction.
  • Increased Productivity: Teams focus on meeting their specific goals, leading to faster issue resolution and improved overall efficiency.

Internal SLAs also help to define expectations for response times, issue resolutions, and the handling of requests between departments. They promote collaboration, clarity, and efficiency, helping teams work together more effectively.

For instance, the HR department might have an SLA with IT to ensure that new hires receive their login credentials within 24 hours, preventing delays and ensuring new employees can start their work promptly.


3. Multi Vendor SLAs

In a world where businesses often rely on multiple third-party vendors for services and support, Multi Vendor SLAs are crucial for setting clear expectations between different service providers.

These agreements define the responsibilities of each vendor, including performance benchmarks, timelines, and service expectations.

Key Aspects of Multi Vendor SLAs:

  • Vendor Responsibilities: Clearly defining the scope of services each vendor is responsible for and ensuring they meet their obligations.
  • Performance Metrics: Establishing benchmarks for each vendor’s service performance, including uptime, response time, and resolution times.
  • Collaboration: Defining how vendors should collaborate and coordinate to meet overall service objectives.

For example, a company that uses a cloud service provider for hosting, a cybersecurity vendor for protecting its data, and an IT support provider for help desk services might have individual SLAs with each vendor.

Each SLA will outline the specific services, response times, and expectations for each vendor, ensuring that all parties are on the same page.

Benefits of Multi Vendor SLAs:

  • Prevents Miscommunication: Clear roles and responsibilities prevent vendors from stepping on each other’s toes.
  • Reduces Overlaps: With clearly defined service expectations, vendors are less likely to duplicate efforts.
  • Improved Coordination: Multi Vendor SLAs ensure that all service providers collaborate effectively to meet the company’s needs.

The goal of Multi Vendor SLAs is to ensure that vendors collaborate effectively and meet their service obligations, without any gaps or overlaps in responsibilities.

For instance, if a company faces a cyber attack, both the cybersecurity vendor and the IT support vendor may need to work together to resolve the issue.

A clear Multi Vendor SLA ensures that both vendors know their roles, the timeline for resolution, and the level of service expected from them.


Final say

Service Level Agreements (SLAs) are integral to the success of customer service, internal operations, and vendor management. The three primary types of SLAs, Customer Service SLAs, Internal SLAs, and Multi Vendor SLAs, all serve to establish clear expectations and ensure efficient operations across different areas of a business.

By understanding and implementing these different types of SLAs, businesses can enhance service delivery, increase efficiency, and ensure customer and internal expectations are consistently met.

SLAs not only create accountability but also foster strong, transparent relationships between businesses, customers, and vendors. Properly defined SLAs are the foundation of effective service delivery and strong business performance.
