Most "Customer Success" Roles Are Not What They Seem: Understanding the True Nature of Customer Success

If you spend any time reading customer success job descriptions today, from CSM to Head of Customer Success, you start to notice a shift in language. Terms like "Own a quota," "Drive expansion revenue," and "Identify and close upsell opportunities" appear frequently. By the third paragraph, you might feel like you're reading a job specification for an account executive with a friendlier title.


This instinct is worth considering because it is largely correct. Many roles advertised as "customer success" today are not, by any rigorous definition, customer success roles. They are sales roles dressed in a softer label. Understanding why this shift is happening and what the discipline is supposed to be is crucial. The confusion isn't just a semantic issue; it impacts hiring, measurement, and ultimately, customer success.


What is Customer Success? The Exact Definition


The most widely cited definition comes from Lincoln Murphy, co-author of the first major book on the subject. His framing is straightforward: "Customer Success is when your customers achieve their Desired Outcome through their interactions with your company." Murphy has refined this wording over the years, but the core idea remains unchanged.


The precision lies in the phrase Desired Outcome, which Murphy breaks into two parts: the Required Outcome (what the customer needs to achieve the job they hired your product to do) and the Appropriate Experience (the way they need to achieve it). You can deliver the functional result and still fail the customer if the experience is not right for them. Conversely, a great experience that never produces the outcome the customer paid for isn't success either.


Two details in that definition do significant work. First, it states interactions with your company — not use of your product. Success is a property of the entire relationship: onboarding, support, billing, and the conversations in between, not just whether someone logs in. Second, it locates success in the customer's goals, not the vendor's. There's a well-known trap here that Murphy calls the "success gap": a customer can tick every box your platform defines as "active" and "adopted" while completely failing to achieve the thing they actually bought the product for.


It's also worth separating two senses of the term. "Customer success" as an operating philosophy is the idea that, in a recurring-revenue business, helping customers achieve their outcomes is the engine of growth; they stay longer, buy more, and advocate. "Customer Success Management" as a function is the operational team and role that puts that philosophy into practice. The philosophy belongs to the whole company. The function is a specific job with a specific remit. Most of the confusion in today's job market comes from collapsing the second into something it was never meant to be.

The Customer Success Manager Skillset: What the Role Really Requires


If we strip away the title inflation, the genuine skill set of a customer success manager is distinctive and notably different from a closer's toolkit. Drawing on the competency models used across the discipline (Gainsight, SuccessCOACHING's Customer Success Competency Model, and others), the core capabilities cluster into a handful of areas:


Domain and Product Mastery


A customer success manager must not only know their own product but also understand the customer's industry, their business problems, and how your solution maps to the outcomes they care about. This knowledge allows a CSM to accelerate time-to-value rather than just answer "how do I do X" questions.


Relationship Management and Emotional Intelligence


Building trust across multiple stakeholders is essential. A CSM needs to read a room, have difficult conversations, and act as a genuine advisor rather than just a vendor. This stewardship role depends on the customer believing that the CSM is on their side.


Problem-Solving and Investigation


A strong CSM behaves like an investigator: finding the real cause behind a complaint, anticipating risks before they surface, and preventing the same issue from recurring across the rest of the book of business.


Data Literacy


Interpreting health scores, adoption and usage signals, and renewal risk indicators is crucial. A CSM must know which of these actually predicts the customer achieving their outcome versus which just look good on a dashboard.


Project Management and Orchestration


Owning onboarding as a structured handover is vital. A CSM must align internal teams and coordinate across support, product, and sales so the customer experiences one coherent relationship.


Cross-Functional Collaboration


Carrying the customer's voice back into product and marketing is essential. A CSM must partner with sales without becoming sales.


Commercial Awareness


Understanding the economics of the account and recognising when a customer is genuinely ready to expand is important. This is real and legitimate, but note the framing. Commercial awareness in service of the customer's outcome is a CS skill. A new-business quota that pressures the CSM to manufacture expansion the customer doesn't need is a different animal entirely.


That last distinction is the fault line the whole hiring market is currently confused about.

Why Do So Many Customer Success Job Descriptions Read Like Sales Roles?


Over the last few years, real economic pressure has pushed the function in that direction, and the job titles never caught up with what was actually being asked.


In a subscription business, growth is arithmetic: if you lose existing revenue as fast as you win new revenue, you don't grow. When net-new customer acquisition slowed and budgets tightened, leadership turned to the existing customer base as the cheapest available source of growth. Net revenue retention (NRR) became the headline metric. Customer success, the team sitting closest to existing customers, was the obvious place to load that expectation.


The data shows how far this went. In G2's State of Customer Success Survey (2024), 67% of customer success professionals reported carrying a sales quota as part of their job. A further 53% said their role now has a sales focus of equal or greater priority than its customer-service responsibilities. Within that group, 11% described their role as strictly sales-oriented while 42% saw sales and support as equally important. So while the headline isn't quite "most CSMs are now salespeople," it is "most CSMs are now measured like them." A separate 2025 ChurnZero study found that fewer than half of CS teams (43%) formally own expansion revenue, even as the pressure to drive it has become near-universal. This is a sign of how far the commercial expectation has outrun the formal mandate.


Some practitioners argue this went too far. Reflecting on the same G2 data, SaaStr's Jason Lemkin noted that customer success has become primarily an upsell-and-sales function in many companies. He asked the obvious question: who, then, is left to help the customer solve the onboarding issue, get the integration working, and keep them from leaving for a competitor? The irony is hard to miss. Pushing CSMs to behave like sellers undermines the trusted-advisor relationship that made them effective at retention in the first place.


There's also a valuation gap underneath all of this. In a 2025 ChurnZero survey, 59% of CSMs said their customer success team is valued less than the sales team, with only 6% saying it's valued more. Sales wins are tangible and time-bound — a closed deal has a dollar figure and a date. Retention and outcome delivery are diffuse and slow. So organisations under pressure default to rewarding what they can see most clearly, and "customer success" gets quietly reframed as the part of sales that happens after the contract is signed.


Customer Success vs Account Management vs Sales


Much of the muddle comes from blurring three roles that should be distinct. Sales (the account executive) owns winning new customers. Account management owns the commercial relationship with existing customers — renewals, upsells, and cross-sells — and has historically reported into sales. Customer success owns the customer achieving their outcomes, which drives renewals and expansion but isn't measured by closing them.


Account management responsibilities have existed in software since long before "customer success" was a job title. What's happening now is that many companies are taking account-management quotas and pasting them onto a customer success label, presumably because the title tests better with candidates and customers. The result is a job description that promises advisory, outcome-focused work in the first half and reveals a carry-a-number sales role in the second. Candidates who are genuinely strong at customer success, with the relationship and outcome skills mentioned above, often discover the mismatch only after they've taken the job.


Why the Mislabelling Matters


This isn't just a purist's complaint about labels. It's Lemkin's question scaled across an industry: when the function gets redefined as upsell-in-disguise, the outcome work doesn't get reassigned; it just stops. Who owns onboarding, the stalled integration, the adoption problem, and the early warning signs of churn? If everyone with "customer success" on their badge is chasing an expansion quota, the work the discipline exists to do quietly goes undone. Eventually, the churn that customer success was created to prevent creeps back up because customers never achieved what they bought the product for.


If you're reading a "customer success" job description that is really a sales specification, you're seeing a symptom of a genuine industry tension, not just sloppy copywriting. The honest move — for hiring managers and candidates alike — is to name it. If the role carries a new-business quota, call it account management or commercial CS, measure it accordingly, and resource the actual outcome work separately. The companies that keep those two things distinct tend to be the ones whose retention numbers hold up. The definition was never the hard part. Living by it under revenue pressure is.

Frequently Asked Questions


What is the Definition of Customer Success?


Customer success is when customers achieve their desired outcome through their interactions with your company; a definition popularised by Lincoln Murphy. "Desired outcome" combines the required outcome (what the customer needs to achieve) with the appropriate experience (the way they need to achieve it). It works as both a company-wide operating philosophy and a specific post-sale function.


Is Customer Success a Sales Role?


Not by definition. Customer success owns the customer achieving their outcomes, which in turn drives renewals and expansion; that is different from owning a new-business quota. In practice, many roles now labelled "customer success" do carry sales targets: in G2's 2024 State of Customer Success Survey, 67% of CS professionals reported having a sales quota. That is a market trend, not the definition of the discipline.


What is the Difference Between Customer Success and Account Management?


Account management owns the commercial relationship with existing customers — renewals, upsells, and cross-sells — and has historically reported into sales. Customer success owns the customer's outcomes, which produce those renewals and expansions as a result rather than as a target. Much of today's confusion comes from attaching account-management quotas to a customer success job title.


What Skills Does a Customer Success Manager Need?


The core competencies include domain and product mastery, relationship management and emotional intelligence, problem-solving and investigation, data literacy, project management and orchestration, cross-functional collaboration, and commercial awareness in service of the customer's outcome distinct from a closer's quota-driven toolkit.


Why Are Customer Success Job Descriptions Becoming More Sales-Focused?


As net-new customer growth slowed, companies leaned on their existing base for revenue, making net revenue retention (NRR) the headline metric and loading that expectation onto the team closest to existing customers. The result is expansion targets and quotas attached to roles still labelled "customer success."
