There’s no shortage of CS software on the market. Health score dashboards, engagement platforms, workflow automation tools, AI copilots — the category has expanded faster than most teams can evaluate it. With that much noise, it’s useful when research cuts through and identifies the specific tools that actually move the needle on retention.
The ChurnZero Customer Revenue Study does exactly that. Across hundreds of CS organizations, four technologies show a statistically significant correlation with better Net Revenue Retention outcomes. Not dozens of tools. Four.

The NRR Gap Is Larger Than Most Teams Realize
Ahead of getting into what the tools are, it’s worth understanding the scale of the gap they create. The data from the study is specific:
Teams using a CRM report NRR of 98.5% versus 90% without one. Teams with a Customer Success Platform report 100% NRR versus 94% without. Teams with a Learning Management System report 99% versus 95% without. Teams with support software report 99% versus 93% without.
That’s a 6 to 10 percentage point gap depending on the tool. In a subscription business, a 6-point NRR gap doesn’t stay flat — it compounds. A team running at 90% NRR loses 10% of its revenue base every year until a single new client is added. A team at 98.5% loses less than 2%. That difference, sustained over three to five years, produces dramatically different business outcomes.
The Four Tools and What Each One Does for Retention
CRM — The Biggest Impact When Missing
The CRM is the foundation. It’s where client data lives, where interactions get logged, and where renewal timelines and account history are tracked. A strong, customer-data-centric stack correlates with higher NRR, and a missing CRM has the greatest negative impact of any single tool. Without it, CS teams are working from memory and scattered notes — a model that fails as soon as account volume scales past what any individual can hold in their head.
Customer Success Platform — The Operational Layer
A CS platform sits on top of the CRM and turns raw data into actionable signals. Health scores, churn risk flags, automated playbooks, renewal tracking — these are the tools that allow a CSM to manage a large book of business without losing visibility into any account. A customer success platform typically increases NRR by six percentage points, making it the single highest-impact investment after the CRM.
Support Software — The Early Warning System
Support data is among the most reliable leading indicators of churn risk. A client who submits five tickets in a month is telling you something. A client whose ticket volume drops to zero after a period of high activity might also be telling you something — and not something good. Support software that integrates with CS tooling turns that signal into a visible alert rather than a data point that lives in a separate system no one is checking.
Learning Management System — The Adoption Driver
Adoption is one of the strongest predictors of retention, and adoption doesn’t happen automatically. Tying your LMS to specific retention goals — activation and time to value — makes it a direct contributor to NRR rather than a standalone training tool. Clients who understand how to use what they’ve bought are clients who have a reason to renew.
It’s Not About Adding More Tools
For Jarrod Haneline, the takeaway from this research isn’t that CS teams need to add four tools to their stack immediately. It’s that these four categories represent specific functions — data foundation, operational visibility, risk detection, and adoption support — that every CS organization needs to execute on, regardless of which specific software they use to do it.
The teams leading in NRR aren’t just investing in technology. They’re integrating it into every operational layer of the customer lifecycle, aligning their tech stack around shared revenue outcomes: renewals, expansion, and customer health.
The tools create the conditions. The CS work done inside those conditions is what actually retains clients.
