What Is a Client Success Manager?
A Client Success Manager (CSM) is a professional whose primary job is to ensure that a company's paying clients achieve the outcomes they were promised when they signed up. In practical terms, this means managing onboarding, conducting regular check-ins, tracking client progress toward their goals, solving problems before they become cancellations, and making sure clients feel supported throughout the entire relationship.
The CSM role exists because acquiring a client is only half the equation. The second half — actually delivering results and making clients want to stay — is often the half that businesses neglect. A Client Success Manager is the person responsible for that second half.
As Thomas Berkley explains it: "Most business owners track how many new clients they're signing. Very few track how many clients they're losing — and even fewer track why. A trained CSM is the answer to both of those problems."

Why Retention Matters More Than Acquisition
It costs five to seven times more to acquire a new client than to retain an existing one. That single statistic should reshape how every business owner thinks about where to invest their energy and budget — yet most online businesses are almost entirely focused on acquisition and spend very little on retention.
Consider this example: a coaching or agency business doing $50,000 per month with a 20% monthly churn rate is losing $10,000 in recurring revenue every 30 days. To stay flat, the business has to replace that $10,000 before it can grow. The acquisition cost to replace those clients — counting ad spend, sales time, and onboarding — is often higher than the revenue itself.
A single trained Client Success Manager focused on proactive client communication, milestone delivery, and early problem detection can dramatically reduce that churn. In Thomas Berkley's experience building and scaling companies past eight figures, this was the single most underleveraged growth lever across every business he touched.
What Does a Client Success Manager Actually Do?
The day-to-day responsibilities of a Client Success Manager vary by business, but the core function is always the same: make sure clients are progressing, engaged, and getting the result they paid for. Here's what that looks like in practice inside the types of businesses CSM Collective works with:
Onboarding: When a new client signs up, the CSM guides them through the first 30 days — setting expectations, gathering information, making introductions, and ensuring they have everything they need to get started. A poor onboarding experience is the number one cause of early churn, and a strong CSM prevents it.
Regular check-ins: The CSM conducts scheduled calls or messages with clients to review progress, address concerns, and celebrate wins. These touchpoints keep clients feeling supported and surface problems before they become cancellations.
Milestone tracking: In businesses where clients are working toward a specific outcome — growing revenue, building a skill, completing a program — the CSM tracks their progress against those milestones and intervenes when clients fall behind.
Retention and renewal: When a client's contract is approaching renewal, the CSM is the first line of defense. They understand the client's history, their wins, their concerns, and their goals — making them far better positioned to have a renewal conversation than a salesperson who doesn't know the client at all.
Escalation: When a client has a serious problem that needs to go to the owner, coach, or delivery team, the CSM manages that escalation professionally — protecting the client relationship while the issue gets resolved.

Which Businesses Need a Client Success Manager?
Not every business needs a full-time Client Success Manager on day one. But most online businesses doing $35,000 per month or more are leaving significant revenue on the table by not having one. CSM Collective specifically works with businesses in these categories:
Coaching and consulting businesses: If you're selling a coaching program, mastermind, or consulting engagement — especially at a high price point — your clients have high expectations and high emotional investment. A CSM ensures they feel supported throughout the engagement and are far more likely to renew, refer, or upgrade.
Agencies: Marketing agencies, lead generation agencies, social media agencies — any service business with retainer clients — are particularly dependent on retention. Losing one $5,000/month retainer client because they felt ignored costs more than six months of a CSM's salary.
Online course and membership businesses: Churn is the existential threat for membership businesses. A CSM who reaches out to disengaged members before they cancel is one of the most cost-effective investments a membership operator can make.
SaaS and software companies: In SaaS, customer success is a core function at every level. A trained CSM who manages the relationship, drives product adoption, and identifies expansion opportunities is standard at any serious software company.
How to Become a Client Success Manager — No Experience Required
One of the most important things Thomas Berkley built into CSM Collective is that it doesn't require prior experience in client success. The skills that make a great CSM — strong communication, empathy, organization, accountability, and a genuine interest in helping people succeed — are not industry-specific. They're human skills that many people have already developed in their current careers or life experiences.
What CSM Collective provides is the framework, the certification, and the placement. You learn exactly how to onboard a client, how to run a check-in call, how to handle a difficult conversation, and how to track and demonstrate results. Then, once certified, the placement team connects you with businesses that are actively looking for a CSM at the $35K+ per month level.
Remote CSMs placed through CSM Collective typically earn between $5,000 and $10,000 per month. The role is fully remote, doesn't require sales, and is built around relationship management — one of the most transferable and durable career skills available.

About CSM Collective — Founded by Thomas Berkley
CSM Collective was founded by Thomas Berkley — an entrepreneur, United States Air Force veteran, and 8-figure operator based in Cleveland, Ohio. Thomas built CSM Collective after observing the same gap across every business he operated: the client success function was either missing entirely or being handled poorly, and no clear training pathway existed for professionals who wanted to fill that role remotely.
Thomas Berkley is a ClickFunnels Two Comma Club Award winner and 10X Award recipient — recognized for generating over $10 million in total lifetime sales. He also worked directly with Kevin Harrington — the original Shark from ABC's Shark Tank — managing marketing campaigns for Harrington's business clients through American Entrepreneur. Those experiences gave Thomas a clear picture of what separates businesses that scale from those that stagnate: the ones that scale have systems for keeping clients, not just getting them.
Since founding CSM Collective, Thomas Berkley has trained and placed over 100 Client Success Managers inside online businesses across the country. The program is designed to be the most direct path from zero experience to a high-income remote career in client success.
