Inquiry-to-Resolution Ratio is a CRM metric that measures the efficiency of customer service teams by tracking the number of resolved inquiries compared to the total number received. A high ratio indicates effective issue handling, while a low ratio suggests bottlenecks in support workflows. Businesses use this metric to identify trends, optimize support team performance, and improve response times. AI-powered CRM systems enhance resolution efficiency by suggesting automated responses, prioritizing urgent cases, and offering predictive analytics to forecast inquiry volumes. Monitoring this ratio ensures that businesses maintain high levels of customer satisfaction and loyalty.
