For people who want to better understand the world of customer service, getting to know the common customer service acronyms experienced professionals throw around is valuable.

  • AHT Average handle time is a metric that tracks how long it typically takes to solve a customer service ticket. Many customer support departments use it to track how well agents are doing at providing a speedy response to customers.
  • CRM Customer relationship management is the practice of working to understand and effectively manage relationships from a person’s first interaction with the company through their entire time as customers.
    CRM is often used to describe the software used for customer relationship management, rather than the practice itself. A CRM system is a technological product that enables companies to effectively track and handle all aspects of customer relationships through the entire customer journey.

Providing excellent customer service is one part of the overall customer experience, and many brands are working to gain a broader view of customer success.
  • KB Knowledge base is a collection of resources on a particular topic. For businesses, internal knowledge bases are used to store and organize important business information. External knowledge bases can be set up to help enable customer self service.

  • BI – Business intelligence is the customer service abbreviation tied to the process of using technology to collect data relevant to the business, and then turning them into actionable insights. Customer service software and the data it produces makes up just one part of BI, but it’s important for giving management visibility into the customer experience.
  • EOD – A general business acronym, EOD means end of day. It’s most often used to clarify deadlines.

For customer service representatives in the U.S. who work in government or healthcare, its most common use will be in Center for Medicaid and Medicare services. Anytime you use it, make sure which meaning you intend will be clear to your audience.
  • CRO – Conversion rate optimization is the process of designing online experiences in a way that increases the percentage of people that take the desired action. While the term is used more often in sales and marketing contexts, this abbreviation can also apply in some customer service scenarios.

Customer service acronyms to guide your agents

When to use (and not use) customer service abbreviations

Customer service acronyms can be time savers when you’re communicating with someone in-the-know. But if you use them in the wrong context, customer service abbreviations can become a barrier to communication.

Many of the acronyms and abbreviations a co-worker understands will cause confusion if you use them with a customer. Some common customer service phrases can’t be reasonably shortened to an acronym without being confused for other common terms. For example, CS could mean customer support, customer success, customer service, or even computer science.

While customer service acronyms and abbreviations are valuable to know, in many cases you’re better off spelling out what you mean to say. Knowing when and how to use them is as important as knowing their meaning.
