A SaaS product needs more planning than a normal website. The system must support users, subscriptions, permissions, dashboards, notifications, billing, support workflows, and long-term scaling.
Before development starts, define the first version carefully. A strong MVP focuses on the core problem, not every possible feature. This keeps cost controlled and helps the product reach users faster.
Good SaaS planning also includes security, database design, cloud deployment, API strategy, and analytics from the beginning.
