SaaS (Software as a Service)

A software delivery model where applications are hosted in the cloud and accessed via the internet on a subscription basis rather than installed locally.

SaaS has become the dominant software model for businesses. Instead of buying and installing software, you subscribe to a cloud-based application accessible from any device with an internet connection.

SaaS Advantages

  • **No installation**: Access from any browser or device
  • **Automatic updates**: Always running the latest version
  • **Scalable pricing**: Pay per user or usage tier
  • **Lower upfront cost**: Monthly/annual subscription vs. large one-time purchase
  • **Built-in collaboration**: Multi-user access and real-time editing

Common SaaS Categories

CRM (Salesforce, HubSpot), project management (Asana, Monday), email marketing (Mailchimp), accounting (QuickBooks Online), and communication (Slack, Zoom).

FAQ

What are the downsides of SaaS?

Recurring costs add up over time, you're dependent on internet connectivity, you don't own the software, and vendor lock-in can make switching painful. Data portability should be evaluated before committing.

Is SaaS secure?

Reputable SaaS providers invest heavily in security — often more than most businesses could afford internally. Look for SOC 2 compliance, encryption at rest and in transit, and regular third-party audits.
