SaaS (software as a service) is cloud-hosted software you access through a browser and pay for with a recurring subscription, usually per user per month.
The short version
SaaS stands for software as a service. You log into it through a browser — sometimes a desktop or mobile app — and pay a recurring subscription instead of a one-time license.
The vendor hosts and maintains it. You just use it.
SaaS vs traditional software, visually
- One-time license purchase
- Installed on a specific machine
- You host, patch and back it up
- Data lives on your device or server
- Monthly or yearly subscription
- Access from any browser or app
- Vendor handles hosting and updates
- Data lives in the vendor’s cloud
Why small teams use SaaS
Three practical wins explain most of the adoption:
- No setup overhead. Sign up, invite the team, ship work the same day.
- Predictable cost. Per-seat pricing scales with team size.
- Always current. No waiting on IT to approve a patch.
The trade-offs are real. You do not own the software, cost accumulates, and your data lives with the vendor. That matters when choosing tools for anything central to the business.
