The difference between traditional software and SaaS lies primarily in their delivery and access models. Traditional software typically requires installation on a user’s local device and often comes with a one-time purchase cost. In contrast, SaaS operates on a subscription basis and is accessible via the cloud, eliminating the need for installation and maintenance. This model allows for greater flexibility, automatic updates, and easy collaboration among users. SaaS can scale more effectively as demand changes, providing organizations with a more adaptable and cost-efficient solution.
