What Is SaaS? A Beginner’s Guide to Software as a Service

Software as a Service (SaaS) is among the most popular ways for businesses and individuals to access software today . Users access applications over the internet, on a subscription basis, rather than buying and installing software on a computer.

From e-mail services and project management tools to customer relationship management (CRM) systems, SaaS solutions are transforming the way that organisations do business. In this beginner’s guide, you’ll learn what SaaS is, how it works, its benefits, common examples, and why it’s become the dominant software delivery model.

SaaS is short for software as a service

SaaS stands for Software as a Service and is a way of delivering software in the cloud. Applications in this model are hosted by a provider and delivered over the Internet to users.

Users log in using a web browser or mobile app instead of installing software on a local device. The SaaS provider handles the infrastructure, maintenance, security, and updates so customers can focus on using the software instead of managing it. 

SaaS is basically a way of “leasing” software instead of buying and maintaining it yourself.

How Does SaaS Function? 

The SaaS applications are hosted on the service provider’s cloud servers. Users access the software online and pay a subscription fee.

How it works: 

  • The provider will create and supply the software.
  • The application is on cloud infrastructure. 
  • Users register and select a subscription plan.
  • Users access the software directly via a web browser
  • The provider will automatically handle updates, security patches and maintenance.

This model does not require complex installations and expensive hardware.

Typical SaaS product examples

Many of the tools that people use on a daily basis are SaaS apps. Such examples include popular:

  • G Suite 
  • Microsoft 365 
  • Zoom 
  • Slack  
  • Dropbox
  • Canva
  • Shopify[4]  
  • Trello, Salesforce, HubSpot

With these platforms users can access services from anywhere there is internet.

Benefits of SaaS

1. Reduced Initial Investment

Traditional software often requires large one-time payments and hardware investments. Most of the SaaS products are subscription based, usually monthly or annually, which makes them affordable.

2. Simple Access

The SaaS applications are hosted on the cloud and the users can access them from any device with an internet connection.

3. Autoupdate

Software vendors frequently provide automatic updates, security patches and new features.

4. Expandability

Businesses can easily upgrade or downgrade plans as per their needs. And so SaaS is good for growing organisations.

5. Improved Collaboration

Many SaaS platforms allow multiple users to collaborate in real time, which increases productivity and collaboration.

Understanding the SaaS Model

The SaaS model is based on recurring revenue. Instead of buying a permanent license, customers pay a subscription fee to use the software. 

The most common pricing models are: 

Subscription monthly 

Users pay a fixed fee each month. 

Yearly subscription 

A discounted rate is offered for customers that pay yearly. 

Freemium Model  

Basic features are free Advanced features require a paid plan 

Pricing Based on Usage

This recurring revenue model offers predictable revenue for providers and flexible payment options for customers.
