A comprehensive guide to customer service SLAs

Support centers are often referred to as the “front lines” of a brand’s relationship with its customers. In ecommerce, establishing clear and consistent customer service SLAs (or service level agreements) is crucial to setting an expectation of support quality in ways you can measure and repeat.

When optimizing your support center, you should establish benchmarks for your SLAs to use as reference points for your success. Then, as your brand matures, those guidelines can be starting points and goalposts to provide better service over time. With powerful service tools like Gladly, your customer service SLAs will continually reflect your company’s commitment to quality in the customer experience.

What is a customer service SLA?

A customer service SLA is the target time within which an agent is expected to respond to a customer. Think of it as a goal to complete a certain number of conversations within a predetermined amount of time — for instance, 80% of chats within two minutes or 90% of SMS conversations within ten minutes.

Types of customer service SLAs

Most support teams work with more than one SLA at a time, and each one tracks something different. Here are the four you'll run into most often.

Customer-based SLA

A customer-based SLA covers everything you promise to one specific customer or account. Enterprise accounts often negotiate their own terms this way, especially when their contract calls for dedicated support or faster response windows than your standard tiers.

Service-based SLA

A service-based SLA applies the same standard to every customer using a given service or channel. If your policy says every email gets a reply within 24 hours, that's a service-based SLA, and it holds regardless of who sent the email.

Multilevel SLA

A multilevel SLA layers the two together: baseline standards for everyone, with additional commitments carved out for specific tiers, plans, or accounts. A retailer might promise 24-hour email response to all customers, then cut that to 4 hours for loyalty members.

Internal SLA

An internal SLA sets expectations between teams inside your own company. Support might promise engineering a same-day response on escalated bug reports, for example, so a customer issue doesn't get stuck waiting on another department.

The importance of SLA

These SLAs are vital to setting a baseline of service between a brand and its customers. Though SLAs are measured internally and not always explicitly known to the customer, every shopper feels the impacts of both meeting and not reaching them.

Understanding customer service SLA performance

Using support standards and previous customer service SLA examples, your brand can start to designate SLAs based on these best practices. Consider the following questions about your SLAs as you measure your consistency in meeting these agreements:

Customer service SLA examples

If your phone agents handle about 60% of their incoming service requests within the first five minutes of the call, this creates your current SLA baseline (60% fulfillment within five minutes) and acts as a performance measurement for goal setting. A brand with these numbers should aim to increase that 60% by 15% within a year to show substantial improvement in service delivery.

Say you found that your agents can fulfill all email service requests in five hours. That means your brand has established an SLA baseline of 100% in a five-hour period for that channel. While the perfect score of 100% sounds optimal for an SLA, you can continue to build off your score to reduce the wait time from five hours to four hours by improving efficiency.

Components of a customer service SLA

A written SLA only works if it's specific enough that both sides can tell, without debate, whether it was met, and these five pieces are what make that possible:

• Scope of service: which channels, request types, and hours the agreement covers

• Performance metrics: the actual numbers, like first response time, resolution time, or first contact resolution rate

• Roles and responsibilities: who owns what, on both the support team's side and the customer's

• Reporting and review: how often performance gets checked and by whom

• Consequences: what happens when a target gets missed, whether that's an internal escalation or a credit to the customer

Building out customer service SLAs

No specific measurements exist for benchmarking SLAs. Rather, the best way to gauge your own SLAs against established baselines is to measure your staff’s response to customer requests based on channel. Once you have an average, translate that information to serve as the benchmark for your SLAs.
