What is Client Health Score?

A client health score is a composite metric that aggregates multiple signals about the strength of a client relationship into a single, actionable indicator. Rather than relying on gut feel or waiting until a client announces they are leaving, health scores provide early warning of at-risk relationships and highlight opportunities for expansion. Building a health score starts with identifying the signals that predict retention and churn at your agency. Common inputs include communication frequency (are emails and meetings becoming less frequent?), payment behavior (are invoices being paid on time?), project feedback (is the client satisfied with deliverables?), scope of engagement (is the client expanding or contracting their work?), NPS or satisfaction survey results, and executive sponsor engagement. Weight each signal based on how predictive it is for your specific business. Most agencies use a simple scoring system—green, yellow, or red—or a numerical scale from 1 to 100. The key is consistency in how you score and regular updates. Many agencies review health scores monthly during account management meetings and use them to prioritize where account managers focus their time. Red accounts need immediate intervention, yellow accounts need proactive attention, and green accounts are candidates for upselling. The real value of client health scores emerges over time as you correlate scores with actual outcomes. Did clients who churned have declining scores in the months before? Did clients who expanded show consistent green scores? This data refines your scoring model and makes it more predictive. Some agencies automate parts of the score using CRM and project management data, while others rely on account manager assessments. The best approach combines both quantitative data and qualitative judgment.
