What is SaaS? How do SaaS businesses work?

ON 21 March , 2025

What is SaaS?

SaaS (Software as a Service) is a computer-based model where software applications are used over the Internet. Users access SaaS applications via a web browser rather than installing them on the local server computer. SaaS applications operate on a subscription-based payment model.

Marc Benioff, the co-founder and CEO of Salesforce, has given SaaS definition as a means of democratizing technology, making high-level software available to businesses of all sizes, for small and medium-sized enterprises (SMEs). He believes that SaaS removes the challenges associated with traditional software deployment, enabling companies to concentrate on their main operations without the burden of managing infrastructure, updates, or maintenance.

SaaS Company Definition

A SaaS company is a business that offers Software as a Service through a cloud-based platform. It provides the software rather than selling licenses to use it. The company also handles software maintenance and security and can host multiple users simultaneously. Sometimes these companies refer other SaaS Development Company to develop their software.

After reading this blog, you will not only learn everything about SaaS but also be able to develop your own SaaS.

History and Evolution of Software as a Service

The journey of SaaS began in time sharing systems to its current dominant phase of cloud systems. SaaS has completely transformed how software is delivered and is still a key player in driving digital change across various industries.

The Origin of Software as a Service Model

The concept of SaaS started in the 1960s, when time-sharing systems on mainstream computers emerged. This system allowed multiple users to access the computer network via terminals, paving the way for the idea of sharing software remotely.

Rise of ASPs (Application Service Providers)

During the 1980s and 1990s, Application Service Providers (ASPs) emerged. They hosted and managed software applications for businesses. The drawbacks of ASPs were that they were expensive and had poor scalability.

Birth of Modern SaaS

With the development and growth of the Internet and cloud computing in the early 2000s, true SaaS solutions were born. Companies like Salesforce (founded in 1999) spearheaded SaaS models by offering CRM over the web.

SaaS Becomes Mainstream

In the 2010s, SaaS became dominant and widely accepted because of its ease in scalability, subscription-based pricing, and Expert API Integration

Major SaaS companies emerged, including:

  • Microsoft Office 365
  • Amazon Web Services (AWS) SaaS offerings
  • Dropbox, Zoom, Slack, Shopify

SaaS vs. Traditional Software

A comparison chart illustrating the differences between SaaS (Software as a Service) and traditional on-premise software, highlighting aspects such as cost, accessibility, maintenance, scalability, and data storage.

SaaS is rapidly becoming the option preferred by businesses because of its flexibility, cost efficiency, scalability, and ease of use. Traditional software is suitable for organisations that need full control, a high level of customisation, and strict security compliance. 

The table below shows a detailed list of differences between SaaS and Traditional Software.

FEATURE SaaS TRADITIONAL SOFTWARE
Server Cloud-Based On-premise local server
Accessibility Accessible by any device with an internet connection Can only be accessed by computers connected to the local server.
Cost and Licensing Subscription based (yearly/monthly) One-time purchase and licensing
Maintenance Automatic updates by SaaS provider Manual installation and updates by the user
Scalability Easily scaled-up and scaled-down as per the need Has limited infrastructure and is difficult to scale.
Customization Limited customization based on service plans. You can develop custom software and infrastructure as per your requirements.
Costs Lower upfront costs (ongoing subscription fees) High upfront costs (especially for licensing and hardware)
Data Storage Stored in the cloud, managed by the service provider Stored in the local server and devices, managed by specialised IT personnel

How does SaaS Work?

Software as a Service (SaaS) is a model for delivering software through the cloud, allowing users to access the application online in any corner of the globe. Here’s how it operates.

Cloud Hosting and Multi Tenancy

SaaS applications are hosted on cloud servers like Amazon Web Services (AWS) and Azure. These applications follow a multi-tenant architecture, where multiple businesses share a single software while keeping their data secure and isolated.

Subscription-Based Software as a Service Access

Most SaaS use subscription-based billing, where users pay monthly or annual fees to access the software. The plans vary, with different levels of storage and features.

Web Based Accessibility in SaaS

You can log into your account through a web browser or mobile app. You do not need to install the software on your device.

Automatic Updates and Security

SaaS providers handle the update and maintenance of the software and its back-end. The SaaS data is stored on secure clouds which comply with industry regulations such as GDPR, HIPAA, or SOC 2 to ensure data privacy and security. This ensures that users always have access to the latest version without disruptions.

What is a SaaS business?

SaaS businesses try to solve the very specific needs of other businesses or end customers by increasing efficiency, implementing automation, or reducing time consumption.

Examples of SaaS Companies:

  • Google Workspace (Gmail, Docs, Drive, etc.)
  • Dropbox (Cloud Storage & File Sharing)
  • Shopify (E-commerce Platform)
  • Salesforce (Customer Relationship Management – CRM)
  • Slack (Team Communication & Collaboration)

What is the SaaS Business Model?

The SaaS Business model offers customers and businesses cloud-based software applications on a subscription-based model.

Features of the SaaS Business Model

Some of the features of the SaaS Business Model are as follows.

Cloud-Based Software: software is hosted on cloud platforms and the users access it via the internet

Subscription: Based Pricing: Users pay monthly or annual subscription fees to use the software.

Automatic Updates and Maintenance: The SaaS provider looks after server updates and security compliances, not the user.

Scalability: Users can scale their needs up or down as per their requirements.

Freemium and Tired Pricing options: Many SaaS businesses offer free trials, limited free plans, or different pricing models.

How to Implement SaaS in Business?

Software as a Service (SaaS) is a useful tool in transforming any business. One can easily integrate SaaS in their business by simply following these steps.

Step 1: Select a SaaS Provider

Identify the software you need, like an ERP or a CRM.

Step 2: Sign Up for the Service

Visit the provider’s website and sign up. Select a pricing plan (free, monthly, or annual)

Step 3: Access the Software

You can log into your account through a web browser or mobile app. You do not need to install software on your device.

Step 4: Use the Software

Start performing your business tasks, like data entry, project management, or document sharing.

Step 5: Regular Updates & Support

SaaS providers automatically roll out updates and security features, so it is advised to always use the latest version.

Step 6: Upgrade or Cancel Subscription

If you need more storage or features, you can upgrade your plans. If the software no longer meets your needs, you can cancel your subscription.

How to Build a Business out of Micro SaaS

Micro SaaS is small, highly category-focused SaaS software, usually developed and run by a single entrepreneur or a small team of developers. It has lower overhead costs and the potential to generate recurring revenue.

Step 1: Identify a Niche Problem

Micro SaaS solves very specific problems. You can do this by finding gaps in existing softwares and platforms. Check for community platforms like Reddit and Indie Hackers for common issues.

Step 2: Validate Your Idea

Before creating a full-fledged solution, test the demand for your SaaS. Create a landing page with a waitlist feature and test the response. To create awareness, post about your solution on LinkedIn and other platforms.

Step 3: Build a Minimum Viable Product (MVP)

Since it is a Micro SaaS, use no-code tools like Bubble or Adalo if you are not a coder and Django or Laravel if you are a coder. Focus on the key problem and keep it simple.

Step 4: Launch & Acquire Early Users

Give early bird discounts to early users of your software and conduct beta testing. Post about your product on different platforms and do content marketing.

Step 5: Monetization & Growth

Launch a subscription plan, such as a monthly or annual plan. You can also white label it for businesses that want to sell it under their brand.

Step 6: Automate & Scale

Automate your software with the help of an AI Chatbot and integrate it with other APIs.

Challenges and Considerations while creating SaaS

Starting a SaaS (Software as a Service) business can be incredibly fulfilling, but it also presents its own set of challenges. Here are some of the main hurdles you might face and tips on how to tackle them.

Identifying a Profitable Market

Many SaaS models fail because the markets are flooded with many softwares. It is a very competitive market with many players and low demand. Thus, focus on solving a specific problem rather than competing with big players.

Choosing the Right Technology Stack for Building SaaS

Poor technology stack leads to scalability and maintenance issues. Building a SaaS product takes time and money, so start with a Minimum Viable Product (MVP) and core features.

Security & Compliance

SaaS businesses handle sensitive data, making them a target for cyberattacks. It is advisable to use encryption and compliance with GDPR, HIPAA, SOC2, depending on your market.

Managing Customer Support & Scaling Operations

As your SaaS scales, customer support & infrastructure must keep up with increasing needs. Hire customer support agents once the user base grows.

Is SaaS Dead?

SaaS is not dead—it’s going through evolutionary changes. Sure, the market is more competitive than it’s ever been, but the demand for cloud-based solutions is skyrocketing. SaaS is changing, and it is not dying. The SaaS market is overflowing with options, featuring countless tools across every category. Just creating “another CRM” or “yet another project management tool” isn’t going to cut it.

Here’s the text we’re looking at: SaaS Is Evolving – What’s Working Now?

  • Micro SaaS & Niche SaaS – Tackle very specific issues for a focused audience.
  • AI-Powered SaaS – Leverage AI to streamline repetitive tasks and enhance value.
