What is Software as a Service: An Introduction to SaaS Companies with Examples

What is Software as a Service?

What Does SaaS Stand For?

Software as a Service, or SaaS as it is commonly known, is cloud-based software that has now become mainstream. 

From small businesses to large corporations, SaaS is the default deployment method for virtually all types of business technology currently available right now.

Its growing popularity is mainly due to the fact that flexible business applications are delivered via a web browser which means no painful installations. And, since services are paid for over a period of time as opposed to all at once, they are a lot more affordable for businesses. 

If you would like to know more about SaaS and how it can be helpful for your company, then read the rest of this article.

In it, we’re going to look at what a software-as-a-service company is and how it works. We’ll also look at the advantages and risks of such companies, as well as 10 examples of some of the most popular SaaS companies around. 

What is SaaS?

Software-as-a-service is a model for distributing software where cloud providers create, manage, and host applications to make them available online to end-users as a service.

SaaS is one of the three main categories of cloud computing, alongside:

  • Platform as a Service (PaaS): These are cloud computing services that offer hardware, software, and infrastructure required for running and managing applications.
  • Infrastructure as a Service (IaaS): These are online services that offer computing, storage, and networking resources on demand.

A software as a service company hosts the application and all related data on its own servers, databases, or networking and computing resources. Alternatively, an ISP can contract the cloud provider to host the software on the provider’s data center.

In this model, third-party cloud providers can be contracted by independent software vendors (ISVs) to host the application. With larger companies, such as Apple or Microsoft, the cloud provider could also be the software vendor.

Who is SaaS For? 

SaaS applications can be used by business users, IT professionals, and personal users. There is a wide range of products, ranging from personal entertainment software like Netflix to advanced IT tools like Scalefusion

Unlike PaaS and IaaS, SaaS products are generally marketed to B2C as well as B2B users. The SaaS industry is currently estimated to be worth US$123 billion and, according to Statista, the market size for global public cloud application services will reach US$145 billion by the year 2022.

How Does SaaS Work? 

The way the SaaS business model works is pretty simple. The software vendor hosts and maintains the software or code that makes up the SaaS application, as well as the servers and databases that allow users to access the application over the internet – most likely through web browsers.or directly on websites, for example those like Ahrefs or SEMrush which uses a SERP API for data mining.  

Users pay a subscription fee, usually monthly, and they can access the SaaS application at any time, from virtually any device with a web browser and internet connection. 

SaaS software subscriptions can be based on a variety of factors, such as:

  • The amount of data that needs to be stored
  • Information design and options for exporting your data
  • How many users will have access to the application
  • The level of technical support required

… and so on.

In this web-based model, which is extremely common now, providers give customers access to the same copy of the application created for SaaS distribution. This means that the source code for the application is the same for every customer. When new features are released, they’re instantly rolled out to everyone at the same time. 

While subscriptions can be a fixed cost for a business, some SaaS platforms will bill customers according to usage and may become a variable expense

What are the Advantages of Saas?

One of the biggest advantages of this software is that instead of having to install and maintain software, you can simply access it over the internet.  Whether you’re looking to build or buy a SaaS product, there are many advantages to the business model. 

In essence, the software sits on the SaaS company’s server and users can access it remotely. This frees you from complex software installations, hardware management, and strict contracts.

Here are a few other benefits of SaaS:

  • No need to manually install and run applications on business computers
  • No expense for hardware purchases, provisioning, and maintenance
  • Eliminates the need for software licensing, installation, and support
  • Offers round-the-clock accessibility regardless of the operating system used
  • Provides automatic upgrades without adversely affecting business operations
  • SaaS is scalable and flexible as you only pay for the features you need 
  • Easily capture data for analytics through visualization, intelligence, and reporting tools
  • Eliminates the need to install and operate the software on computers which gives businesses access to enterprise-level software
  • The company can continue to tweak the platform to boost conversions

Of course, with benefits come the risks. 

Risks of SaaS

Although this is a ready-made solution that requires no setup or maintenance, it does come with a few drawbacks.

For instance, SaaS poses a few potential challenges and risks since businesses are completely reliant on outside vendors to not only provide the software but also keep it running smoothly, track and report accurate billing, and ensure a safe environment for their data. 

Other risks include the following: 

  • Although most SaaS companies have flexible systems, upgrading capacity could come with a steep price increase.
  • Data security is entrusted to a third party and some SaaS companies are not transparent about security standards.
  • In case of an unreliable third party, the SaaS company could experience downtime which could adversely affect your business.
  • If the SaaS company goes out of business, businesses could be cut off from accessing the service and/or their data.

Furthermore, other issues could arise that are equally beyond the customer’s control such as the vendor experiencing a security breach or imposing unwanted changes to their service offerings. 

Fortunately, the best SaaS companies have systems in place to mitigate most, if not all of the risks outlined above.
