In one sentence: SaaS (Software as a Service) is software delivered over the internet on a subscription basis, accessed through a browser rather than installed and maintained directly on a user's own computer or servers.

Most business software used today is SaaS, even when people don't think of it that way โ€” logging into a website to use a tool has simply become the default, rather than installing a program locally.

How SaaS Differs From Traditional Software

Traditional software was purchased once, installed locally, and manually updated. SaaS runs on the provider's servers, is accessed through a browser, and updates happen automatically without any action from the user.

๐Ÿ’ก Did You Know?

The shift to SaaS has been so complete that many people under a certain age have never installed traditional, locally-run business software at all โ€” logging into a web app is simply the only model they've known.

Real Considerations With SaaS

Businesses rely on the provider's uptime and continued existence, and typically have less control over customization compared to self-hosted software โ€” trade-offs worth weighing for critical systems.

Frequently Asked Questions

Is SaaS the same as cloud computing?

Related โ€” SaaS is one specific category of cloud computing (alongside IaaS and PaaS), referring specifically to ready-to-use software delivered over the internet.

Do I need to install anything to use SaaS?

No โ€” that's the core defining feature of SaaS, accessed entirely through a web browser without local installation.

Is SaaS more expensive than traditional software over time?

It varies โ€” SaaS often has lower upfront cost but ongoing subscription fees, which can add up differently than a traditional one-time software purchase.

What happens to my data if a SaaS provider shuts down?

This is a real consideration โ€” reputable providers offer data export options, but dependency on a provider's continued operation is a genuine trade-off.

Can SaaS software be customized?

Generally less than self-hosted software, though many SaaS platforms offer meaningful configuration options and integrations.

Is most modern business software SaaS?

Yes โ€” the vast majority of commonly used business tools today (CRMs, project management, communication tools) are delivered as SaaS.
