ROI (Return on Investment) is a financial metric that evaluates the profitability of an investment relative to its cost. In CRM, ROI analysis helps businesses assess the effectiveness of marketing campaigns, sales initiatives, and customer acquisition strategies. A high ROI indicates that a campaign generates significant returns compared to its expenses. CRM systems provide insights into ROI by tracking key performance indicators (KPIs), such as customer acquisition cost (CAC) and customer lifetime value (CLV). Businesses that optimize ROI can maximize profits, reduce inefficiencies, and improve decision-making.
