What Is SaaS? Software as a Service Explained Simply

Industry Insights · 7 min read · Published · By MeetBridge

SaaS stands for Software as a Service. It is a way of delivering software over the internet as a subscription instead of installing it on your computer. Instead of buying and installing software, you access it through a web browser and pay monthly or annually.

Popular examples of SaaS: Gmail (email), Slack (messaging), Salesforce (CRM), Zoom (video meetings), Shopify (e-commerce), HubSpot (marketing), Notion (productivity), Dropbox (file storage), and thousands more. If you use software through a browser and pay a recurring fee, it is likely SaaS.

How SaaS works: The software runs on the provider's servers (cloud). Users access it through a web browser or app. The provider handles maintenance, security, updates, and hosting. Users pay a recurring subscription (monthly or annually). Multiple users share the same infrastructure (multi-tenant architecture).

SaaS pricing models: Per-user pricing (Slack charges per user per month), tiered pricing (free, basic, pro, enterprise tiers), usage-based pricing (AWS charges based on what you use), freemium (basic features free, premium features paid), and flat-rate pricing (one price for all features).

Advantages of SaaS: No installation or hardware required, accessible from any device with internet, automatic updates and maintenance, lower upfront costs (subscription vs large one-time purchase), easy to scale up or down, and free trials let you test before committing.

Disadvantages of SaaS: Requires internet connection, data is stored on third-party servers, subscription costs add up over time, limited customization compared to on-premise software, and vendor lock-in can make switching difficult.

The SaaS market is projected to reach $900 billion by 2028. The average business uses 130 different SaaS products. This explosive growth has created massive opportunities for SaaS companies, their partners, and affiliates.

SaaS and affiliate marketing: Many SaaS companies offer generous affiliate programs because the recurring subscription model means high customer lifetime value. An affiliate earning 30% recurring commission on a $100/month SaaS product earns $360/year from a single referral — and that compounds with every new customer.
