The Revenue Is Already There. Is Your Customer Success Team Ready to Capture It?

Sales teams know exactly what they’ve closed and what it’s worth. They track it, celebrate it and get paid on it. Customer success teams, on the other hand, often manage the majority of company revenue with a fraction of that same visibility — and a fraction of the investment to support them in it.

Nearly three-quarters of customer success (CS) and growth leaders (74%) say a majority of their company’s revenue now comes from existing customers. And companies with customer success managers (CSMs) on the team reported a 98% NRR, compared with 90% without them.

So why do 59% of CSMs still believe their employer values sales over customer success?

The gap isn’t capability. It’s how CS gets resourced, structured and treated as a strategic function — and sales leaders have more influence over that than they realize.

Customer Success Owns More of the Revenue Cycle Than You Think, and the Math Proves It

For years, new logo acquisition has been the default growth strategy.

Existing customers, it turns out, are where the returns actually are. Forrester finds that current customer renewals and expansions account for over 60% of B2B revenue. Seventy-three percent of CSOs say growth from existing customers is a top priority for the year, and 57% rank account retention and growth among their top three priorities.

The team responsible for delivering that growth? Customer success. CS leaders say their teams are primarily responsible for renewals (54%) and expansion revenue (37%). Sales, by comparison, owns just 12% of renewals and 25% of expansion.

CSMs are working a different angle than sales reps, one built on outcomes, not transactions. It’s a different dynamic — and it’s why the post-sale relationship drives retention in a way the sales relationship can’t.

How to Structure Customer Success as a Revenue Driver

Most CS leaders just want the conditions to do their job well. Here’s where that tends to break down, and what sales leaders can do about it.

Pair revenue ownership with the training to back it up

Assigning the CS team specific revenue metrics — NRR, expansion ARR and logo retention — is already happening at many organizations. But measurement alone isn’t enough. CSMs also need the skills to drive those numbers.

Sales and negotiation skills top the list of self-identified weaknesses among CSMs, cited by 42% of respondents in a confidential CSM survey. Business skills, like interpreting metrics and creating strategy, follow at 37%. But these skills are the building blocks of revenue-generating conversations. For CS teams to effectively own revenue, they also need structured training in commercial acumen, negotiation and business strategy to close the gap between having a number and knowing how to hit it.

These aren’t soft skills—they’re the same commercial skills sales teams have been trained in for years. Chief among them is the ability to inspect a deal and disqualify revenue opportunities early, using the same pipeline and deal scorecards that keep sales teams from wasting cycles on the wrong accounts. That discipline is largely absent from CS teams today, even those who own both renewals and upsell targets.

Establish rules of engagement for expansion

CS and sales often pursue expansion without a shared definition of who owns what, creating ambiguity and leading to preventable tension across many teams. Will CS or sales be responsible for identifying the opportunity? Who leads the conversation with the customer if there’s interest in expansion? How will the credit be split if the sale goes through?

Most companies haven’t answered those questions cleanly, and both teams feel it. CS and sales end up chasing the same customers with different incentives, without a shared strategy, leaving customers stuck in the middle.

For both teams to work well together on revenue generation, sales and CS need clear, documented, and agreed-upon processes tied to how they are measured, so that expansion shifts from a potential source of friction into a source of revenue.

The conversation isn’t about the handoff. It’s about defining what a “ready to expand” customer actually looks like. When that definition exists, a sales rep can flag it during the sales process, and CS can pursue the qualified lead post-sale. That’s a fundamentally different approach than CS’s accidental discovery of expansion opportunities.

Shared programs, like extending recognition for CS results on retention and expansion, are among the more direct ways to signal that both teams are playing for the same number. That number is the company’s revenue. Sales brings it in. CS protects it and grows it. And the incentive structures should reflect that.

Make customer data a company-wide asset

Expansion and renewals become more likely if customer intelligence flows freely across the organization. It’s unlikely CS will manually update sales, marketing or product after every customer conversation. There’s simply not enough time in the day to relay the full picture of what customers are experiencing and what they are asking for. Data has to do that work.

If NRR is going to grow, customer data needs to be centralized and accessible across the entire go-to-market team so everyone can operate from the same picture without CS serving as the sole source.

Invest in CS as a strategic capability

For decades, sales teams have built on CRMs like Salesforce. Marketing has had platforms like HubSpot. Both roles have the data infrastructure to make their work measurable, repeatable and scalable.

CS has been running behind on that infrastructure for a long time. CS teams that are expected to drive retention and expansion but lack the technology to track, automate and scale that work are set up to underperform. You can’t ask a team to perform like a revenue team and give them the tools of a support function.

Investing in a purpose-built CS tech stack provides infrastructure for the growth motion the business is already counting on. In fact, companies that use a customer success platform (CSP) report 100% NRR compared to 94% without one. And those with a CRM report 98.5% versus 90% without.

Building for After the Closed-Won

When CS and sales work together around a shared number — with clear rules around expansion, CSMs trained to have the right commercial conversations and technology that actually supports the work — the credit fights go away. The handoff arguments go away. What’s left are two teams that understand what the other one needs to win, a customer who can feel the difference and sustainable recurring revenue for the business.
