The key to tracking the right metrics for a SaaS company is understanding its unique business model and needs. Metrics like new user churn rate, natural rate of growth (NRG), burn multiple, activation velocity, expansion revenue, and customer lifetime value are crucial for making informed decisions and driving sustainable growth. Other important metrics include revenue churn, customer acquisition cost, net promoter score, months to recover CAC, LTV-to-CAC ratio, leads by lifecycle stage, average first response time, average resolution time, customer health score, and customer engagement score. To measure these metrics effectively, companies should focus on understanding the "why" behind the data, know the three metrics buckets (finance, marketing, and sales), and not try to measure everything. Additionally, automating workflows with tools like Zapier can help streamline key functions of a business, freeing up time for more important tasks. By tracking the right metrics and using automation tools, SaaS companies can drive growth, improve customer satisfaction, and increase profitability.
