30 common customer service acronyms

Maybe you’re a brand new customer support representative, an experienced customer service manager, or a member of a sales team trying to make sense out of your communications with customer service. Whatever your role, bookmarking this list of customer service and call center acronyms can help you more effectively communicate with your colleagues.

  1. AHT - AHT stands for average handle time, 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.
  2. AI - A common shortening for artificial intelligence, AI is a hot topic in the business world in general, and often comes up in the context of technological customer support tools. For example, chatbots that employ AI can take a portion of customer service work off the shoulders of human agents.
  3. BI - BI, or business intelligence, is the term tied to the process of using technology to collect data relevant to the business, and then turning it into actionable insights. Customer service software and the data it produces makes up just one part of BI, but it’s important for allowing management to gain visibility into the customer experience.
  4. CEM - CEM stands for customer experience management, the collection of processes, tasks, and tools a business deploys to understand and improve the customer journey. A key part of CEM is gaining a single view of the different interactions a customer has with a brand and how they all connect, so you can understand their larger customer experience.
  5. CMS - In the world of customer service and particularly in call centers, this stands for call management system. It’s a central piece of call center technology that helps agents more efficiently handle large volumes of calls.

    Be warned: CMS is an acronym where context really matters. Its most common business use is to describe a content management system, which may include a customer service knowledge base. And for customer service representatives in the U.S. who work in government or healthcare, it’s most common use will be Center for Medicaid and Medicare services. Anytime you use it, make sure which meaning you intend will be clear to your audience.
  6. CRM - CRM stands for customer relationship management, 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.

    In practice, 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, throughout the full customer journey.

  7. CRO - Conversion rate optimization, or CRO, 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, it can also apply in some customer service scenarios.
  8. CSAT - A shortening of the term customer satisfaction, CSAT is used to describe a score produced from providing customers with a short survey asking them to rate their service experience.
  9. CSS - In the customer service industry, CSS stands for customer self service, a type of customer support that’s focused on providing customers with the information they need to solve their own problems. It includes resources such as a thorough customer help center or AI chatbot that allow customers to find an answer without having to talk to a person.

    Be warned: A more common usage of CSS, especially in technological fields, is to describe the programming language cascading style sheets. If programmers or developers are in your audience, that’s what they’ll think of when they hear this acronym.
  10. CTA - A CTA, or call to action, is the language used to encourage a prospect or customer to take a specific step. Common examples include “contact us” or “learn more.”
  11. CTI - Computer-telephony integration is any type of product that enables companies to integrate their phone and digital interactions in one interface.
  12. CTR - CTR is a shortening of click-through rate, the percentage of clicks that a link gets, as compared to the number of views it has. While the metric is more common in marketing than customer service, it can be a useful measure for determining how well support articles are performing.
  13. CX - A common way of shortening the phrase customer experience, CX is a term that’s used to describe taking a larger look at how a customer perceives and interacts with a brand than simply their customer service interactions. 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.
  14. EOD - A general business term, EOD means end of day. It’s most often used to clarify deadlines.
  15. EOL - End of life is a term used to describe when a piece of technology, or a particular version of a piece of technology, will no longer be supported by a company. That can include no longer providing customer support for it.

  17. HR - HR, or human resources is the department in a business devoted to hiring, training, and managing employee benefits and complaints. While most of customer service is focused on helping the external customer, HR representatives often see their job as providing internal customer service.

It can include inspecting inventory to ensure it works as expected, doing user testing for a software product, or tracking and analyzing customer service metrics.
  22. ROI - Return on investment, frequently shortened to ROI, is a business term used to measure how well the amount spent on products and labor is paying off in terms of profits.
  23. SaaS - Software-as-a-Service is a business model based on selling a subscription to a piece of technology that will be renewed monthly or yearly.

  28. UI - The user interface is the part of a software the user interacts with directly. It plays a key role in UX, and how well it’s designed can influence how often customers need help from support versus being able to figure out how to use a product on their own.
  29. VOIP - Voice over Internet Protocol is the technology that allows people to make phone calls using broadband internet. It’s a common feature in modern customer service contact centers.
  30. WOM - WOM, or word of mouth is what your customers and prospects have to say about your brand. Building positive word of mouth is one of the best signs of customer service success.

When to use (and not use) customer service acronyms

Customer service acronyms can function as time savers anytime you’re communicating with someone in the know. But if you use them in the wrong context, they can become a barrier to communication.

Many of the acronyms a co-worker understands will cause confusion if you use them with a customer. And 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 are valuable to know, in many cases you’re better off spelling what you mean to say. Knowing when and how to use them is at least as important as knowing their meaning.
