CSM vs. AM: Who Drives B2B SaaS Expansion Deals?

Defining responsibility for expansion revenue is critical to a company's growth strategy. Traditionally, Customer Success Managers (CSMs) and Account Managers (AMs) hold distinct roles, but their collaboration can significantly impact Customer Lifetime Value (CLV) and expansion success. Let us take a closer look at these roles, their interplay with new sales and the most suitable approaches for different organizational needs.

Customer Success Managers (CSMs)

CSMs ensure that customers achieve their desired outcomes with the company's products or services, focusing heavily on customer satisfaction and continuous engagement. They monitor product usage, support onboarding and proactively address customer issues. This trust-based relationship can organically lead to growth and upsell opportunities.

Key responsibilities of CSMs include:

1. Onboarding new customers and ensuring smooth product adoption

2. Monitoring customer satisfaction metrics and health scores

3. Regular interactions with customers to provide support and gather feedback

Account Managers (AMs)

AMs focus on the financial aspects of customer relationships, managing renewals, upsells and cross-sells to ensure ongoing purchases. They build long-term relationships, negotiate contracts and resolve conflicts. Their success is measured by revenue growth and CLV.

Key responsibilities of AMs include:

1. Building and maintaining long-term customer relationships

2. Managing contract renewals and negotiations

3. Identifying and pursuing upsell and cross-sell opportunities

When to Use Which Approach

CSM-Led Expansion: For companies offering complex products that require extensive customer support, CSMs are well-positioned to drive growth. Their deep understanding of customer needs and product usage helps identify organic growth opportunities and facilitate upsells.

AM-Led Expansion: In scenarios where expansion opportunities demand aggressive sales tactics, such as entering new departments or selling new product lines, AMs are better suited. Their expertise in negotiations and closing deals makes them ideal for managing complex sales processes.

Hybrid Approach: Many successful SaaS companies, such as HubSpot, rely on a hybrid approach where CSMs and AMs work closely together. In this model, CSMs focus on customer satisfaction and adoption, while AMs pursue potential upsell opportunities.

The Role of New Business & Sales

In many startups that lack dedicated Account Management roles, responsibility for expansion falls to either CSMs or Sales teams.

CSM-Led Expansion in Startups: CSMs often take on additional expansion responsibilities, leveraging their deep customer relationships to identify upsell opportunities.

Sales-Led Expansion in Startups: This strategy is effective when expansion requires introducing entirely new products or entering new markets.

Collaborative Approach in Startups: A collaborative approach where CSMs and Sales teams work together can also be highly effective.

Conclusion

Deciding who owns expansion revenue – CSMs or Sales teams – depends on the specific needs and structure of the organization. For SaaS companies looking to balance customer satisfaction with aggressive growth targets, a collaborative approach can be the optimal strategy.
