Optimizing pricing for a SaaS business involves several steps, including analyzing current pricing strategies, understanding customer usage data, engaging with customers directly, and forming a dedicated pricing committee. It is crucial to evolve pricing as the company grows by leveraging data and technology to experiment and optimize. Pricing should be based on customer willingness to pay rather than solely on competition or cost-plus models. Regularly running pricing experiments across different metrics and geographies can help find the most effective strategy, leading to increased revenue and reduced churn.
