What Is SaaS? Software as a Service Explained Simply

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.
