Software as a Service — software delivered over the internet on a subscription basis.

SaaS eliminates the need for organizations to install and run applications on their own servers or devices. The provider manages all infrastructure, maintenance, and security, allowing customers to access the software via a web browser or API. This model has become the dominant delivery method for business software due to its lower upfront costs, automatic updates, and built-in scalability. Popular examples include Google Workspace, Salesforce, and Slack. Buyers should weigh subscription cost growth, data portability, and exit paths alongside the convenience of managed delivery, since multi-year dependence accrues quietly. Contract terms, security attestations, and integration fit deserve the same scrutiny as any other enterprise purchase. Renewal terms and data export rights complete that review.
Why SaaS matters when choosing software
SaaS can affect software selection differently depending on the workflow, team size, and category. Use the definition above as the starting point, then check how the concept appears in the products you are evaluating. In practical terms, look for the controls, limits, integrations, reporting, or operating assumptions that are directly related to SaaS. A useful comparison should explain what the concept means, where it matters, and what evidence a buyer can verify before committing.
How to evaluate it in a real product
Start with the workflow that depends most on SaaS. Identify the requirement, ask the vendor for the relevant documentation or configuration details, and test the requirement with realistic sample data where possible. Then compare the result against alternatives rather than treating a marketing label as proof. Related concepts in this category include API, Open Source, Freemium.
