What is SaaS – Understanding Software as a Service 

Software as a Service, also known as SaaS is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the internet. Using such a service, customers don’t need to install and configure the applications since the software provider handles them.

In the software on-demand SaaS model, the provider gives customers network-based access to a single copy of an application that the provider created specifically for SaaS distribution. The application’s source code is the same for all customers and when new features or functionalities are rolled out, they are rolled out for all customers. Depending upon the service level agreement (SLA), the customer’s data for each model may be stored locally in the cloud or both. Organizations can also integrate SaaS applications with other software using application programming interfaces (APIs).

Over the last decade, SaaS has been replacing traditional on-premises licensed software for customers ranging from small shops to multinational tech giants. SaaS has become one of the well-known applications in the world of cloud computing. By empowering organizations to host and license their software application from the cloud server, SaaS application development has become a go-to solution these days.

Why SaaS – Reasons to prefer SaaS for your business

The value and need for SaaS products have evolved and grown tremendously over the years, and we can clearly see the trend to continue in 2021 and for years to come. 

The continued shift from traditional on-premises license software to subscription-based SaaS models, with the increased need for new software collaboration tools during COVID-19, is driving SaaS growth. As a result, Software as a service remains the largest market segment and is forecast to grow to $104.7 billion in 2020. It comes from the fact that nearly all software market segments are being driven by SaaS implementation.

As stated in Statista, the global public cloud software as a service (SaaS) market is forecast to reach 157 billion U.S. dollars in size in 2020, more than doubling the market size in 2014.

SaaS MarketCompanies using Cloud-based apps with the SaaS business model are increasing in number, the reason being, it is based on the subscription model and has numerous benefits. Age-old business applications are now going out of the present IT plans of many businesses. The ability of fast deployment with lower investment risk has made business owners choose SaaS solutions over other traditional choices. 

Today, most businesses across the globe are struggling to sustain themselves in the market while managing the workforce due to the coronavirus pandemic. Such transformation has posed a big question in front of the organizations – “How to manage the IT infrastructure while everyone is working remotely?” 

The answer is simple – SaaS development. The increased need for collaboration software during the COVID-19 pandemic has driven further growth of the SaaS market. The effects of the global economic downturn are intensifying organizations’ urgency to move off of legacy infrastructure operating models.

Modern SaaS technology is realized in a huge variety of options. It allows building platforms that can connect apps, integrate the Internet of things (IoT) solutions, and analyze big data. IoT and big data are considered to be the most popular technology trends. That is why learning how to build a SaaS product is a highly worthwhile investment.

Advantages of SaaS

SaaS solutions have a high potential for improving the business. Below we’ve singled out a few core advantages of a SaaS architecture for both users and developers.

No hardware and maintenance – The biggest advantage of SaaS software distribution over traditional software delivery methods is that it saves organizations from having to heavily invest in hardware and install, configure, and run apps locally. Organizations also don’t have to worry about maintenance, support, and licensing stuff. The apps are ready to use as soon as a subscription is confirmed, which translates into quick deployment and rapid prototyping.

Scalability and Flexibility – The main advantage of SaaS applications is adding capacity. Businesses can subscribe to a SaaS offering and pay-as-they-go, while in most cases they can handpick the features and only pay for the required features. SaaS apps are highly scalable, allowing businesses to access more features and services as they grow.

Cost efficiency – In contrast to on-premise solutions offering a license for an upfront cost, the SaaS model has different subscription plans. Using a SaaS service, there is no need to buy and maintain expensive hardware. It’s common for SaaS solutions to offer paid subscriptions. So, the company pays for the required functionality and can stop paying if the business doesn’t need the service.

Compatibility and Accessibility – SaaS solutions can be accessed through a web browser on almost any device, which results in great cross-platform compatibility. This allows users to access information from anywhere even using their mobile devices, which boosts productivity and efficiency.

Security – The SaaS vendor’s livelihood depends on data security, so it is only natural that safeguarding the app is paramount. SaaS providers usually have their servers scattered in multiple geographical locations and have automatic backups, ensuring a higher level of security than your enterprise itself would be able to provide. According to Gartner, 95% of cloud security failures are due to human error. The cloud is secure and your data is safe. 

Automatic updates – Since everything is hosted in the cloud, there are no local updates and the service provider is responsible for the automatic deployment of updates. This also saves businesses from the hassle of testing updates before deploying them. Because the SaaS provider manages all updates and upgrades, there is no wait time for new features and enhancements, and are delivered as soon as they’re ready.

App Integration – SaaS applications can be integrated with other platforms and systems using APIs. This allows organizations to integrate their systems with the SaaS provider using their APIs. Businesses can choose the offerings of SaaS providers that have better integration with other systems and leverage their existing IT investment.

Stability and Predictability – SaaS application development is a promising scenario for startups. A SaaS company can expect to attract a considerable customer base with moderate up-front fees and then rely on a fairly stable and lasting source of revenue.

Higher Customer Lifetime Value – It’s much easier to offer upgrades and expanded services mix to users of your SaaS products. So you can scale SaaS applications easily and boost your revenues.

No Piracy – Since it’s not very easy to pirate cloud-based software, SaaS helps companies to reduce the piracy of their software.

To put it shortly, SaaS products provide a great solution with remarkable benefits to businesses struggling with traditional and inefficient in-house systems. Because of said benefits, SaaS is a rapidly expanding niche, many entrepreneurs and developers are getting into the realm of SaaS Application Development to help enterprises solve their issues.

The stages of a SaaS business

For every SaaS business, there are three primary stages that they go through – Setup, Growth, and Stabilization. 

Stages of saas developmentSetup – The setup stage is where companies build a foundation. This is where you’ll be working on the product and marketing it to new customers. This is also an ideal time to identify your target audience, create an effective marketing and sales strategy, and consider your options for customer support.

Growth – This stage implies data expansion, bandwidth, and all sorts of technicalities to support users’ accounts. After your product reaches the market, you may experience a great deal of growth. New customers will quickly adopt your product, creating a sudden demand for your marketing, sales, and customer service teams. Your business will need to act quickly to capitalize on this timely opportunity to secure a loyal customer base. An inability to successfully handle growth is where many SaaS companies fail.

Stabilization – This is the stage where your SaaS business model levels out. You are making a healthy profit, acquiring new users quickly, and experiencing churn. That’s because you have wisely reinvested in customer service software, marketing automation, and product updates. This level helps you to keep pace with customers’ demands and offer a delightful user experience.

Factors you should consider when adopting a SaaS solution

While there are many considerations when choosing to deploy a SaaS model, the following perhaps are the most important factors you’ll need to consider.

Market Research 

Market research is critical to your SaaS product’s success. It helps you learn more about how your customers think, their purchasing patterns, software proficiency, and more. Market research is also an excellent way to monitor your competitors so that you can maintain a competitive advantage. 


Financial considerations come first and foremost. You need to define your product and development costs. Business owners must strive to build a holistic solution that caters to the requirements of various departments. 

Technical Specifications

This is the point where you need to determine how your software will be built. Not every technology and programming language will be the right fit for your SaaS product. It is why having the right framework for your SaaS product is crucial. It would be best to make sure that your SaaS product is built on top of scalable software architecture, so you can upgrade the product without wasting too much of your team’s time and resources.

Define the MVP

Having a Minimum Viable Product (MVP) means figuring out what are the basic core features that will bring value to your customers with minimal costs from your side. An easy way to define the MVP is to answer questions like what problem you are solving, what is your target user’s persona, what actions users take to solve their problems, and what solutions you can propose.

Security and Performance

While building a SaaS model, it is crucial to ensure maximum security as it is the foundation of a good solution. Consumers’ requirements are constantly evolving so you should be able to adjust to them. Your software should also be built in such a way as to handle the increasing amount of users without slowing down.

There are many factors to consider when choosing a deployment method and every situation is indeed unique. We hope the points provided above offer some aspects to consider during your software development cycle and help guide your decision to making the best choice to realize your business objectives.
