Customer Success vs Customer Support: What is the Difference in 2025?

Customer success and customer support are often confused, but they serve fundamentally different purposes. Understanding the distinction—and how they work together—is essential for building a customer-centric organization.

This guide breaks down the differences, explains when you need each function, and shows how the best companies leverage both to drive growth and retention.

Quick Comparison: Customer Success vs Customer Support

Focus	Proactive value delivery	Reactive problem-solving
Goal	Customer retention and growth	Issue resolution
Trigger	Success milestones, health scores	Customer-initiated contact
Metrics	NRR, expansion revenue, churn rate	CSAT, resolution time, ticket volume
Approach	Strategic partnership	Transactional service
Typical Team Size	Smaller, higher-touch	Larger, broader coverage
Revenue Impact	Directly drives expansion	Indirectly protects revenue

What is Customer Support?

Customer support is the traditional service function that helps customers when they encounter problems. It is reactive—waiting for customers to reach out with issues, questions, or complaints.

Core Responsibilities of Customer Support

Problem Resolution Support teams troubleshoot technical issues, answer product questions, and resolve complaints. Their primary job is fixing what is broken.

Multi-Channel Assistance Modern support spans multiple channels:

• Live chat and messaging
• Email support
• Phone support
• Social media
• Self-service portals

Knowledge Base Management Support teams often maintain FAQs, help articles, and documentation that enable customer self-service.

Escalation Handling When issues require specialized expertise or higher authority, support manages the escalation process.

Key Metrics for Customer Support

• First Response Time (FRT): How quickly you initially respond
• Average Resolution Time: How long it takes to fully resolve issues
• Customer Satisfaction (CSAT): Post-interaction satisfaction ratings
• First Contact Resolution (FCR): Percentage resolved without follow-ups
• Ticket Volume: Total support requests over time
• Net Promoter Score (NPS): Likelihood to recommend

When You Need Strong Customer Support

• High-volume products: Many customers with diverse questions
• Complex products: Technical products requiring troubleshooting
• E-commerce: Order issues, returns, and shipping inquiries
• Any business: Every company needs some form of customer support

What is Customer Success?

Customer success is a proactive function focused on ensuring customers achieve their desired outcomes with your product. Rather than waiting for problems, success teams anticipate needs and guide customers toward value.

Core Responsibilities of Customer Success

Onboarding and Adoption Customer success managers (CSMs) guide new customers through implementation, training, and initial adoption. The goal is to ensure customers start getting value quickly.

Health Monitoring Success teams track customer health scores based on usage patterns, engagement, and satisfaction indicators. This allows them to intervene before problems arise.

Expansion and Upselling CSMs identify opportunities for customers to get more value through additional features, higher-tier plans, or new products.

Strategic Partnership Unlike transactional support, customer success involves ongoing strategic conversations about business goals, challenges, and opportunities.

Renewal Management Success teams often own or heavily influence the renewal process, ensuring continued relationships.

Key Metrics for Customer Success

• Net Revenue Retention (NRR): Revenue retained and expanded from existing customers
• Gross Revenue Retention (GRR): Revenue retained without accounting for expansion
• Customer Churn Rate: Percentage of customers lost over time
• Expansion Revenue: Revenue from upsells and cross-sells
• Time to Value (TTV): How quickly customers achieve their first success
• Customer Health Score: Composite score indicating account health
• Product Adoption Rate: Usage of key features and workflows

When You Need Customer Success

• Subscription/SaaS businesses: Where recurring revenue depends on retention
• High-value accounts: Where individual customers represent significant revenue
• Complex products: Where customers need guidance to realize value
• Long sales cycles: Where post-sale relationship building matters
• Competitive markets: Where differentiation comes from customer experience

The Fundamental Differences

1. Reactive vs Proactive

Customer Support waits for customers to reach out. A customer experiences a problem, contacts support, and receives help. The interaction begins with a customer action.

Customer Success initiates contact proactively. A CSM notices a customer is not using a key feature, reaches out to offer training, and helps them adopt it—before they ever complain or churn.

2. Problem-Focused vs Outcome-Focused

Customer Support asks: "What is the problem, and how do we fix it?"

Customer Success asks: "What is the customer trying to achieve, and how do we help them get there?"

Support addresses symptoms. Success addresses underlying goals.

3. Transactional vs Relational

Customer Support typically involves one-off interactions. A ticket is opened, resolved, and closed. The relationship resets with each new issue.

Customer Success builds ongoing relationships. A CSM knows the customer's business, goals, history, and challenges. Each interaction builds on the previous ones.

4. Cost Center vs Revenue Center

Customer Support is traditionally viewed as a cost center—necessary but not directly revenue-generating. (Though great support absolutely impacts retention.)

Customer Success is increasingly viewed as a revenue center. Success teams directly influence renewals, expansions, and referrals.

5. Scale Model vs High-Touch Model

Customer Support often operates at scale, handling large volumes of interactions with efficiency as a priority.

Customer Success typically operates high-touch with smaller portfolios of accounts per CSM, prioritizing depth over breadth.

How Customer Success and Customer Support Work Together

The most effective organizations do not view these as competing functions—they are complementary parts of the customer experience.

Shared Goals

Both functions ultimately serve the same purpose: making customers successful and happy. Their approaches differ, but their destination is the same.

Data Sharing

Support interactions provide valuable signals for success teams:

• A customer filing many tickets may have adoption issues
• Common support questions reveal product gaps
• Resolved issues impact customer health scores

Success insights inform support quality:

• Account context helps support prioritize
• Success playbooks can become support resources
• Strategic goals shape how issues are resolved

Escalation Paths

When a support issue indicates deeper problems—onboarding failure, feature misunderstanding, potential churn—it should escalate to customer success for strategic intervention.

When a success conversation uncovers immediate technical issues, support should be engaged for resolution.

Handoff Points

Clear handoff protocols ensure smooth customer experiences:

• After sales closes → Customer success for onboarding
• Technical issues during success calls → Support for resolution
• Support uncovers growth opportunity → Success for expansion
• Success identifies at-risk account → Support for intensive engagement

Building Both Functions: A Practical Framework

Small Business (Under 50 Customers)

Customer Support: Founder or early team members handle support. Use tools like Oxaide to automate FAQs and provide 24/7 coverage even without a dedicated team.

Customer Success: Founders or sales reps maintain customer relationships. Focus on high-value accounts personally while using automation for others.

Growing Business (50-500 Customers)

Customer Support: Hire dedicated support reps. Implement proper ticketing, knowledge bases, and quality standards.

Customer Success: Hire your first CSMs to manage strategic accounts. Segment customers by value and provide appropriate touch levels.

Scaling Business (500+ Customers)

Customer Support: Build tiered support with specialized teams. Invest in AI and automation for common issues.

Customer Success: Build out the success team with portfolio-based CSMs, success architects, and onboarding specialists. Create scaled success programs for smaller accounts.

The Rise of Customer Experience (CX)

Many organizations are moving toward unified Customer Experience (CX) functions that encompass both success and support. This recognizes that:

1. Customers do not care about internal org charts
2. Their experience spans both functions
3. Data and insights should flow freely
4. Consistent excellence requires alignment

A CX approach does not eliminate the distinct roles—it aligns them under shared leadership, metrics, and philosophy.

Metrics That Bridge Both Functions

Customer Lifetime Value (CLV)

Both functions contribute to CLV. Support affects it through satisfaction and retention. Success affects it through expansion and strategic growth.

Net Promoter Score (NPS)

NPS reflects the overall relationship, shaped by both support interactions and success engagement.

Customer Effort Score (CES)

How easy is it to do business with you? Both functions impact this perception.

Customer Health Score

A composite metric that incorporates support interactions, product usage (success), engagement levels, and business outcomes.

Common Mistakes to Avoid

1. Treating Them as the Same Thing

They are not. Conflating success and support leads to underinvestment in proactive work—because reactive issues always seem more urgent.

2. Building Success Before Support

Some startups hire CSMs before establishing basic support. Result: CSMs spend all their time firefighting instead of driving value.

3. Siloing Data

When support and success do not share information, customers experience disjointed interactions. "I already explained this to your colleague" is a customer experience failure.

4. Measuring the Wrong Things

Measuring support by resolution time alone ignores quality. Measuring success by activities rather than outcomes misses the point.

5. Underinvesting in Technology

Both functions benefit enormously from the right tools—ticketing systems, health scoring platforms, automation, and analytics. Do not force teams to work with inadequate resources.

Industry-Specific Considerations

SaaS

Success is critical. With monthly recurring revenue, every customer relationship directly impacts the business. High-touch success for enterprise accounts, scaled success for SMB.

E-Commerce

Support dominates. Most customer interactions are transactional—order issues, returns, product questions. Success exists in loyalty programs and VIP customer management.

Healthcare

Support handles patient inquiries and administrative questions. Success helps healthcare organizations achieve clinical and operational outcomes with your product.

Financial Services

Support addresses account questions and transactions. Success manages relationships with business clients and helps them achieve financial goals.

Professional Services

Success is often embedded in service delivery itself. Support handles operational and administrative issues.

Conclusion

Customer support and customer success are distinct but complementary functions:

• Support reacts to problems and resolves them
• Success proactively guides customers toward outcomes

The best organizations excel at both. They build strong support foundations that handle issues efficiently, while investing in success functions that drive retention and growth.

As AI becomes more capable, the line continues to evolve. Automation handles more routine support, freeing humans for higher-value success work. But the core distinction remains: fix problems vs. drive outcomes.
