SaaS, also known as Software as a Service, has become a popular choice for businesses of all sizes to access and utilize software applications without the need for upfront capital investment. The SaaS business model provides a flexible, scalable, and cost-effective solution for accessing software applications over the Internet, making it a more and more desirable solution for entrepreneurs.

In this article, you’ll explore the basics of SaaS, its benefits, and the different factors that businesses should consider before adopting SaaS.

What is SaaS?

SaaS is a Cloud-based service, that gives the end users access to applications over the Internet. This means that users can access the software application through a web browser or mobile app without the need for on-premise installation or maintenance.  

This opens a world of opportunities for businesses to increase their size and speed up their product launch process. The fact that SaaS has gone mainstream is not surprising. Data shows that the SaaS industry has been on continuous growth since 2015 and by the end of 2023, it is expected to be worth approximately $195 billion U.S. dollars. If you've been thinking about launching a SaaS product, there's no better time than now to do it.

How does SaaS work?

There are two main ways in which the traditional on-premise software delivery model differs from SaaS:

  • SaaS deployments don’t require extensive hardware. It enables buyers to outsource most of the IT responsibilities that are usually required to troubleshoot and maintain the software in-house.
  • SaaS systems are usually paid within a subscription model. On the other hand, on-premise software is typically purchased through a perpetual licence and paid in advance.

The benefits of SaaS (advantages)

The SaaS model eliminates the need for companies to install and operate applications on their own devices or servers, which saves them money on hardware acquisition, setup, and upkeep, as well as software licensing, installation, and support. Additionally, the SaaS model offers other advantages such as:

  1. Payment flexibility:
    The SaaS model works on a subscription-based pay-as-you-go approach, allowing customers to manage their finances more effectively by selecting licensing options that suit their requirements and paying accordingly. Moreover, SaaS models offer the flexibility to cancel the contract at any time, therefore it eliminates recurring expenses.
  2. Scalability:
    Clients always have the option to review their licensing model and adjust the number of services they require based on their current business needs.
  3. Simpler upgrades:
    The IT departments don't need to worry about managing difficult software upgrades with SaaS, as the service provider takes care of them. SaaS users always have access to the latest version of the software. Moreover, when a SaaS is delivered through a multi-tenant architecture, the software provider can easily offer new updates and upgrades to all users in all the subscribing companies.
  4. Accessibility:
    As SaaS vendors provide applications through the Internet, they can be accessed from anywhere with an Internet connection.
  5. Easy customization:
    SaaS applications can often be customized to meet specific needs and can be integrated with other business applications, particularly those from the same software provider.

Disadvantages of SaaS applications

SaaS, however, can also present some disadvantages for businesses. This is because they have to depend on external vendors to provide and maintain the software, accurately bill for the service, ensure the software runs smoothly, and maintain a secure environment for their data.

  1. Risk of service termination
    If the provider has to stop offering the service, the customer won't be able to keep using it and might lose all the data they shared with the provider. However, in most cases, if the company goes bankrupt, for instance, the vendor informs the user beforehand so that they can recover their data.
  2. The need for a good Internet connection
    SaaS applications are very convenient because they can be accessed through a web browser, however, they rely on a good internet connection. A slow internet connection is one of the disadvantages as it can cause delays and make the application inaccessible. This can be especially frustrating for people who work outside the office. This issue can disturb the effective use of SaaS, and result in financial losses in the long run.
  3. Security
    When it comes to SaaS applications, one of the biggest challenges is ensuring cloud security. If you're working with sensitive information, you need to be extra careful about how you manage identity and access. This is particularly important with cloud-based solutions because there's always a risk of data leaks, hackers trying to get in, and other security incidents that could put your information at risk.
  4. Inaccessible during downtime periods
    If a SaaS application is built with a multi-tenant architecture, it means that when the service goes down on the provider's end, customers will be unable to access the application.
  5. Limited features
    While SaaS can be customized to a certain extent, there are limitations to what you can do. When you subscribe to a hosted application, you're limited to the features and functionalities that the solution provides, which may not be enough to cover all of your business needs and use cases.

What factors need to be considered before adopting SaaS?

Before choosing a SaaS application, it’s important for businesses, to keep in mind several factors that will help ensure that the solution is the right fit for their specific needs. These factors include:

  • Integration: Check if the SaaS application can integrate with your current systems, like CRM, ERP, or HR systems, which can make your processes more efficient.
  • Customization: Determine whether you can customize the SaaS application to fit your specific needs, including the ability to add or remove features, functionality, and branding.
  • Security: Ensure that the SaaS application complies with industry standards and regulations, and has features like data encryption, backup, and disaster recovery, to protect against security threats and reduce the risk of data breaches.
  • Support: Make sure the SaaS provider offers enough support, including technical support, training, and onboarding, to help you successfully adopt and use the application.
  • Pricing: Understand the pricing structure of the SaaS application, including subscription fees, usage-based pricing, and any extra costs for customization, support, and training.
  • Server infrastructure: Take into account the budget, availability of experienced DevOps, and the potential of free credits or tokens from cloud service providers like Amazon, Microsft, Google, or others.

These considerations can help optimize the performance, cost-effectiveness, and scalability of the SaaS application, leading to improved overall efficiency and effectiveness.

What is a Software as a Service company?

A SaaS company is a business that creates, develops, hosts and maintains a specific software product for customers to access through the Internet. The great thing about running a SaaS company is that you can reach customers all over the world, and the costs of delivering your product don't increase as you add more users. This makes it easier to scale your business and grow quicker than other business models.
