Client vs. Customer – What’s the Difference?

English is the primary language in several prominent Western capitalist societies, so it should come as no surprise that the language has multiple words for people who buy things.

There is no shortage of goods and services available for purchase, but exactly what someone pays for is an important component of how we describe them.

Client and customer are two words for individuals (or even groups or businesses) who pay for goods and services. Is there a meaningful difference between client and customer?

What is the Difference Between a Client and a Customer?

In this post, I will compare client vs. customer. I will use each word in at least one example sentence, so you can see how it appears in context.

Plus, I will show you a memory tool that you can use to make choosing client or customer much easier.

When to Use Client

client versus customerWhat does client mean? The word client is a noun. A client is someone who engages the services of a professional.

Attorneys and accountants have clients because people and businesses engage them for their legal and financial services, respectively.

Here are a few more examples,

  • The firm fired one of its CPAs because her behavior caused them to lose an important client.
  • Government officials were frustrated when the attorney refused to reveal information about his client.
  • Gary Cohn, White House Economic Council director, told the Wall Street Journal in an interview published last night that the administration would also move against a regulation designed to force retirement advisers to work in the best interest of their clients. –The Washington Post

Like so many English words, client has origins in Latin, and came to English through French. English speakers have been using the word since at least the 14th century.

When to Use Customer

For example,

  • When the customer tried to return her television at the register, the cashier directed her to customer service instead.
  • The once popular tavern lost multitudes of customers when it replaced its cheap drinks and simple pub food with fancy cocktails and elevated dining options.
  • On a muggy morning in July 2008, hundreds of customers stood outside IndyMac Bank branches in Southern California, trying to pull their savings from the lender, which was doomed by losses on risky mortgages. –The Wall Street Journal

In a literal sense, a customer is someone who gives custom, where custom is a somewhat archaic word for regular business. 

Trick to Remember the Difference

define client define customerThere is a bit of overlap between client and customer. A client is obviously buying the services of an attorney or accountant, so, in some sense, he or she is a “customer.” And customers can buy services instead of physical goods.

In practice, client is usually reserved for someone who pays for highly specialized professional services, while customer describes someone who makes purchases at a store or other business, especially on a regular basis.

At the risk of oversimplifying the difference,

  • Professionals like attorneys and accountants have clients.
  • Retail stores like grocery stores and restaurants have customers.

If you can remember that custom means regular business, it should be easy to remember that a customer is someone who regularly shops at stores or other businesses.

Summary 

Is it customer or client? The nouns client and customer both refer to people who purchase things.

Traditionally, a client pays for highly specialized professional services, while a customer shops regularly at a store or other business.

There is still some overlap between them, but careful writers use each word in its proper context.
