Customer Success Manager

The Customer Success Manager (CSM) is the professional who works with customers after the sale to help them use a solution and achieve useful outcomes. They connect customers' objectives with their use of the product and maintain an ongoing relationship with their contacts. Their role involves understanding what the customer wants to achieve, identifying obstacles and coordinating the necessary actions.

This job profile primarily describes the role in businesses that sell subscription software to other businesses, or B2B SaaS. In this context, customer guidance goes beyond initial onboarding: it focuses on the value gained throughout the relationship. The CSM may be involved when the customer first gets started or take over from a team responsible for deployment.

CSM, customer support and commercial account management: who does what?

• The CSM monitors the account's objectives, adoption and risks. They help the customer make progress and involve the relevant teams.
• Customer Care / Support handles requests for assistance and incidents. The CSM may coordinate the response to a problem without taking responsibility for its technical resolution.
• Commercial account management covers contractual discussions, depending on the organisation. The CSM may prepare for an upcoming deadline or identify an opportunity without having the authority to negotiate.

These responsibilities can overlap. To write a usable job description, specify which accounts the CSM will handle, when they become involved and which decisions they can make. Also identify their manager, their commercial contacts and the teams able to resolve product issues. A job title alone does not establish this division of responsibilities or the depth of technical knowledge expected.

A customer may have a solution without managing to integrate it into their work. Customer Success aims to connect product use with expected outcomes: effective onboarding, obstacles addressed and value that the customer can explain. Adoption, satisfaction, retention and opportunities to grow the account are among the aims of the role. Having a CSM does not, in itself, guarantee these outcomes.

For the business, another priority is to understand a relationship before it deteriorates. A decline in usage or persistent difficulties warrant investigation; on their own, they are not enough to explain the customer's intentions. Account reviews should make it possible to compare the data with conversations with users and decision-makers. This understanding helps identify an appropriate action rather than increasing contact without a clear purpose.

Fictional example: a business has deployed software, but one customer team makes little use of it. The CSM seeks to understand whether the issue stems from onboarding, a technical obstacle or an objective that has become less important. Depending on the findings, they arrange guidance, involve a team with the relevant expertise or revise the plan with the customer.

The outcome then depends on several contributors. Sales, product, support and services also contribute to the customer's success. It would therefore be risky to assess the person in the role solely on outcomes they do not fully control, without considering the resources and decision-making options available to them.

When hiring, the fundamental choice concerns the actual need: developing product use, coordinating complex accounts or strengthening continuity in account management. Combining these expectations with poorly defined commercial responsibilities can make it difficult to balance priorities. Specifying what takes precedence when demands compete gives the role a more coherent remit.

• Clarify the customer's objectives and agree on the outcomes to monitor.
• Organise how the account will be managed, either from the outset or following a handover from a deployment team.
• Document a shared plan with actions, owners and review points.
• Analyse usage to identify obstacles and propose actions suited to the customer.
• Review progress and difficulties with the account's contacts.
• Identify risks and coordinate the response with the relevant teams.
• Prepare for upcoming account deadlines by sharing outcomes, risks and opportunities with the designated commercial lead.
• Maintain usable customer information to ensure continuity in account management across teams.

Several backgrounds can prepare someone for a Customer Success Manager role. Experience in post-sale customer relations, support, deployment or professional services can provide relevant knowledge and skills. Its relevance depends on the responsibilities actually held and the remit of the role being filled. Having handled incoming requests is not enough to demonstrate the ability to manage an account over time.

Training in marketing and customer relations is another possible route. The French certification « Manager du marketing et de la relation client » lists the role among its career outcomes. This does not make that training compulsory: recruitment should focus on the knowledge and skills useful to your product and customers.

Finally, adapt your expectations to the complexity of the role. Working with customers on a specialised solution requires different product and business knowledge from managing a portfolio with more homogeneous needs. Identify what the person must already know and what they can learn with the team. This distinction helps compare varied backgrounds without inferring ability solely from a qualification or length of experience.

To assess a Customer Success Manager, adapt the following steps to the accounts, product and responsibilities you intend to assign to them.

1. Set criteria based on the role's remit

Choose a short assessment grid before the interviews: understanding an account, analysing usage, prioritising, building a plan and communicating. Specify what you expect for each criterion.

For a complex portfolio, place greater emphasis on coordinating contacts. If the role includes commercial responsibilities, add the contractual decisions the person will actually be entrusted with. Distinguish skills that are essential on arrival from knowledge the team can pass on.

Ask someone who knows the customers and how the product works to conduct the role-specific interview. If this expertise is not available internally, involve an experienced Customer Success professional in this part of the assessment.

2. Examine a specific experience

Ask the candidate to describe how they managed an account whose situation changed. Clarify the initial objective, the information available, their personal role and the other teams involved.

An account plan, account summary or project presentation can support this discussion, anonymised where necessary. Ask the candidate to explain the choices that guided their work.

Then ask questions about their decisions: why was this action prioritised? What information was missing? How did the customer contribute to the choice? What was revised afterwards?

A strong answer distinguishes the candidate's actions from collective contributions and explains the limits of the outcome. An account based solely on a good personal relationship leaves the analysis and organisation of account management still to be examined.

3. Set a case close to the work expected

Fictional example: a customer's use of the solution is declining, their main contact has just changed and an issue remains open with support. A contractual deadline is approaching.

Provide some usage data, a history of conversations and known commitments. Ask the candidate what information they would seek, whom they would contact and what initial actions they would propose.

Observe their ability to distinguish an observation from a hypothesis. Ask them to justify the order of actions and specify the contributions expected from support or the commercial lead.

A positive sign is a clear plan that relates to the customer's objectives and can be adjusted as missing information becomes available. A promise of renewal or an immediate conclusion based solely on usage deserves further questioning.

4. Observe communication and coordination

Ask for a short presentation of the case aimed at the customer, followed by an internal summary. Compare the clarity of the message, the level of detail and the next steps communicated.

Introduce an expectation that the product cannot meet immediately. Examine how the candidate clarifies the request and explains the options without making a commitment they may not be able to keep.

If the role includes people management, add a situation requiring them to resolve competing demands between team members. Assess this responsibility separately from account management.

5. Cross-check the decisive evidence

Request professional references with the candidate's consent. Prepare questions about the responsibilities held, cooperation and how they handle difficult situations.

Then bring the observations together in the initial assessment grid. Explain reservations and points that remain unknown, rather than replacing them with a general impression. Base the decision on the actual requirements of the role.
