SaaS & Internet Earning

SaaS (Software as a Service) is software provided as an ongoing service. This category covers the economics and technology of small SaaS businesses, micro-SaaS and digital products: recurring revenue, pricing, customer acquisition, automation and operating costs.

Revenue, contribution margin and available cash describe different things. MRR is monthly recurring revenue; churn measures losses. Hosting, payment fees, AI usage and support affect margins. Annual subscriptions and lifetime deals change cash flow and future service obligations.
