The skills needed for customer success manager roles have changed fast, and if you’re hiring for or working in this position, you’re probably feeling that shift.
A few years ago, CSMs were mostly found at SaaS companies, helping users get comfortable with software. Now? The role has spread across technology, healthcare, education, and just about every industry that cares about keeping customers around.
And the data backs up why. Organizations with dedicated Customer Success teams see a 14.3% increase in both gross and net retention rates, according to Gainsight’s CS Index Report. That’s real money walking out the door, or staying, depending on how well your CSMs are equipped.
In fact, the global customer success management market is projected to reach $12 billion by 2032, growing at about 14.78% per year. Companies aren’t investing in Customer Success because it sounds nice. They’re doing it because it returns $1.67 for every dollar invested, according to industry benchmarks.
So which skills separate the CSMs who move the needle from those who just manage inboxes? Here are 20.
That’s why many professionals look beyond operational skills and focus on planning for long-term financial stability that doesn’t hinge on any single client or segment.
The Role of the Customer Success Manager
The Customer Success manager (CSM) sits between sales and support, and that position is trickier than it sounds.
The sales journey usually starts with a salesperson or business development rep. When prospects become customers, support or service teams step in. A CSM acts as a single point of contact through all of it, keeping the handoffs smooth and the relationship personal.
The position doesn’t look the same at every company.
At one organization, the CSM might work side-by-side with salespeople, contacting, informing, and supporting prospects. At another, they’re part of an implementation team alongside technical account managers, walking customers through installation or first-time use.
And at others, they take on more of a sales administration role, easing the workload on reps while keeping the connection warm for potential buyers.
A mid-size financial services firm in the Midwest (name withheld) recently told an industry conference that after adding two CSMs to their sales team, their customer retention rate jumped 18% in one year.
The CSMs didn’t close deals. They kept people from leaving. That’s the job.
Regardless of how a company defines the duties, CSMs need to build and sharpen specific skills.
The 2024 CSM Confidential Report from ChurnZero and SuccessCOACHING found that CSMs themselves identified gaps in analytics, forecasting, metrics, strategy, and negotiation training.
Only 40% said their workloads and schedules were realistic.
The skills below cover what CSMs need to handle that workload and do the job well.
The Core Skills That Set Great CSMs Apart
1. Communication
Customer Success managers could put “communicator” on their business cards, and it would be accurate.
They make sure the right information flows from the organization and salespeople to prospects at the right time and place. They also need to get customers to share information back and relay it to the people and departments that need it.
CSMs need to speak and write well. Because so little of their work happens face-to-face, they spend most talking time on the phone or video calls. A strong, competent tone matters. Clear, vivid language matters more.
And they write constantly: email, social media messages, chat responses. Some contribute to sales and marketing content too. Solid grammar skills and command of language aren’t optional here.
2. Relational Intelligence
People with relational intelligence read others quickly and accurately, then use that read to connect and build rapport. It’s a skill that separates average CSMs from great ones.
This goes beyond finding a shared interest or hometown connection.
CSMs need relational intelligence to align their messages with what prospects actually need and want. Some prospects prefer a warm, friendship-style business relationship. Others want transactions and results, nothing personal.
The CSM who can identify the difference early and adjust their approach will build stronger connections every time.
3. Mental Fortitude
Dealing with prospects who are reluctant, confused, or frustrated is tough on anyone. Dealing with those situations every single day is the reality for Customer Success managers.
A positive outlook helps here, and that’s largely instinctive. You can’t teach someone to be genuinely enthusiastic. But enthusiasm paired with a real concern for others can carry a CSM through the days when prospects flounder, systems crash, colleagues snap, and products fail.
The ChurnZero 2024 report found that 68% of CSMs report being happy in their roles, which is above the U.S. workforce average of 62%. That suggests most people in this role already have some of this wiring.
4. Organizational Accuracy
CSMs need to be organized and accurate. They stay on task and follow through on commitments, with the flexibility to shift priorities when circumstances change.
How? They use tools to manage time, messages, and promised actions. But deeper than technology, they have personal systems and habits for prioritizing and completing work.
They don’t leave things to chance. Backup plans exist if the original approach fails, along with checks to make sure things actually got done.
5. Confidence
CSMs can’t be timid. By nature of the job, they’re regularly in situations where they need to take control and make fast decisions based on limited or pending information and what they know about a prospect’s needs.
Some confidence is natural. The rest comes from thorough, ongoing training and the freedom to try new approaches, then learn from both wins and missteps without serious consequences.
If your organization punishes CSMs for taking reasonable risks, you’re training them to be passive. And passive doesn’t move prospects through the pipeline.
6. Relationship Building
It’s just as important for CSMs to build relationships inside the organization as it is with prospects. CSMs are often parts of multiple teams at once.
They need to cooperate across departments. They need to listen closely to colleagues, offer constructive input, and accept guidance, so teams function well.
A CSM who only builds external relationships will eventually hit a wall when they need internal support to solve a customer problem.
7. Discernment
CSMs work with colleagues and customers who are often concerned about one thing: themselves. That’s human nature.
Discernment helps CSMs choose which battles to fight with colleagues and which customer demands to accommodate.
They practice this by asking more questions to understand why others are reluctant or combative. Then they respond to the underlying need, which is usually self-serving, in a way that gives everyone something they can accept.
8. Handling Difficult Conversations
CSMs face a lot of uncomfortable conversations about money, accountability, and missed expectations. Great CSMs address these head-on rather than avoiding them.
When CSMs establish themselves as problem-solvers and advocates, they earn the credibility to bring up tough topics with a respectful, professional, matter-of-fact tone.
The trust has already been built. The conversation becomes about solving a problem together rather than assigning blame.
9. Sociability
CSMs have to genuinely like people. People in Customer Success positions don’t get easily irritated by others’ quirks, habits, and personality traits.
They need to be comfortable talking to anyone, regardless of background or current mood. They should be genuinely interested in other people and prove it by listening closely and showing they care about what they hear.
If this sounds like an easy bar to clear, spend a week in a high-volume CSM role, and you’ll see why it isn’t.
10. Empathy
Customers want to be heard, understood, and validated. Anyone working in a customer-facing sales role needs empathy, and CSMs need it more than most.
Empathy in action for CSMs means anticipating prospects’ pain points before they bring them up, recognizing how prospects feel at the moment, and clearly showing how you plan to make things better.
A LinkedIn analysis of CSM skills found that emotional intelligence is now one of the top differentiators between average and high-performing CSMs, especially as more interactions happen through digital channels where tone is harder to read.
11. Responsible-Tasking
You might assume CSMs need to be great at multitasking, given the volume of emails, phone calls, chats, and meetings they juggle. They do have a lot on their plates.
But research from Stanford University shows that heavy multitaskers make more errors, have more trouble filtering out distractions, and retain less information.
CSMs need what’s better described as responsible-tasking: the ability to move from one prioritized task to the next so everything gets done well. Not at the same time. In the right order.
12. Proactivity
There’s little downtime in Customer Success. CSMs react to prospects’ and customers’ requests and concerns. And when they aren’t reacting, they need to proactively gather more information to prepare for what’s coming next or stay ahead of another request.
The best CSMs are busybodies in the best sense: they find ways to fill limited free time that create value. That might mean reviewing a customer’s usage data before a call, preparing a summary of recent product updates, or flagging a potential issue before the customer notices it.
13. Strategic Thinking
CSMs are problem-solvers who carry prospects through most of the sales cycle. Obstacles show up at every stage, and CSMs need to help prospects move past them while making the process feel smooth and effortless.
That requires spotting issues and possibilities early, planning for each, and helping prospects have more positive experiences throughout their buying journey. It also means using strategic thinking to anticipate what competitors can and will do to pull the deal away.
14. Analytical Skills
CSMs handle large amounts of data every day. They need to understand where the information comes from, how it affects the customer journey, where they stand with each prospect, and what they can do with the data to move things forward.
That means getting comfortable with data from surveys, buying patterns, demographics, behaviors, engagement metrics, and feedback specific to their industry and customer base.
The ChurnZero report found that CSMs themselves rank analytics as one of the skill areas where they need more training.
15. Professional Agility
CSMs work with higher-level buyers and executives. They need to quickly learn the rhythms of business and finance within those organizations.
And they need to relay that information up, down, and across chains of command, often translating it, so each audience understands the impact of what’s being shared.
CSMs need the desire and ability to learn business processes, organizational operations, and company goals. If they’re always playing catch-up on how their own company works, they can’t credibly advise customers on how to succeed with its products.
16. Perceptive Skills
Internal and external changes can affect the customer journey at any point. CSMs need perceptive skills to recognize shifts in their product, operations, or market and adjust the customer experience accordingly.
At the same time, they need to watch for changes in customer demands, their customers’ own business challenges, and organizational shifts. Those often trigger issues that need immediate attention to keep prospects from dropping out of the pipeline.
17. Assertiveness
CSMs are like quarterbacks. They lead others, call plays, and help the team execute, so prospects move quickly and smoothly through the sales cycle.
To do that well, they need to tell others what needs to be done and when. That requires walking a fine line: leaning toward assertive and away from aggressive. The difference? Assertive CSMs state what’s needed with clarity and respect. Aggressive ones make it personal.
18. Counterintuitive Thinking
CSMs sometimes need to challenge their prospects in a positive way. They get to know prospects, their businesses, pain points, and concerns so well that they can see solutions the prospect hasn’t considered.
Then they need to push prospects to think in new ways, so they understand the full value of what’s being offered. This is where CSMs shift from being helpful to being indispensable. A CSM who only agrees with the customer’s perspective will never show them a better one.
19. Resilience
CSMs can’t give up. They often need to dig into the root cause of a prospect’s or customer’s problem and find the right solution. Sometimes they need to bring in others who are better suited to help.
In either case, resilience means following up as many times as necessary to get to the bottom of the issue and keep the prospect satisfied.
Research shows that a 5% increase in customer retention rates can lead to a 25% increase in profitability. Every prospect saved by a persistent CSM has a direct impact on the bottom line.
20. Teaching
CSMs need teaching skills and a level of comfort instructing others. They walk prospects through systems and product or service trials. They often take new customers through first-time use.
And because they’re frequently ahead of the curve on product updates and best practices, they may need to bring salespeople and internal teams up to speed on changes and upgrades too. A CSM who can teach a complex feature in plain language is worth their weight in contract renewals.
Building These Skills Takes Intention
The Customer Success management market is projected to grow at 11.14% annually through 2035, according to Market Research Future. That means more companies will hire CSMs, and competition for the best talent will increase.
If you’re a CSM, pick two or three skills from this list that feel like your weakest areas and focus there. If you manage a CS team, use this list as a development framework. Match each skill to your team members’ strengths and gaps, then build training around the gaps.
The companies that invest in these skills now will see it in their retention numbers. The ones that won’t keep wondering why customers leave.
