The question of why SaaS product development has become so popular can be answered by looking at the advantages of software development and overall maintenance. Meanwhile, the users have also acknowledged the distinctive functionality that differentiates these products from regular applications for desktop and mobile platforms.

Since the data is stored in the cloud, they are not bound to use the same device all the time. Another thing is that users get rid of on-premise downloads and it doesn’t take any space on the customers’ devices.

SaaS software development is a reasonable choice for businesses. It will be much easier to deploy your product. The software runs on the server, so your project requirements won’t depend on numerous configurations of every platform. Maintenance and updates are faster to be implemented as well. 

Moreover, SaaS application development is a flexible solution for businesses that want to keep pace with rapidly-changed technologies. This distribution model enables them to enter the market faster and deliver the latest features within a short timeline and reasonable cost. At the same time, the customers have also emphasized this product as a budget-friendly option due to the subscription pricing model. Users have the possibility of using up-to-date and fully functional software products.


Every company that is interested in building and marketing the application successfully has to be familiar with the SaaS development life cycle. It ensures the continuous delivery of the product and efficient implementation. Consider the following phases of SaaS development life cycle.

SaaS development Life Cycle


The business strategy is an essential part of any development. Always start with finding business opportunities and ways to attract new customers. Taking into account the distinctive abilities of cloud services, identify the value you are going to deliver. In addition to the development strategy, you should think about the marketing strategy way ahead. 

Platform evaluation

Making a choice on the SaaS application development platform, remember that it should acquire certain capabilities. Since the final architecture has to acquire great performance, reliability, compliance, scalability, the chosen platform has to provide the necessary tools.


As long as you have defined the necessary requirements, it is time to plan step-by-step implementation and focus on the development solutions. Your project plan should cover details regarding not only its functionality but timeline, cost, and required specialists.  However, it should be divided into stages and suggest the long-time vision options.

Subscription model

It is an important step in the SaaS development life cycle to acquire a production quality subscription. In order to make the right decision on the cloud platform and the central hosting model, you should trial the chosen services and prepare all the required documentation. Reach the necessary level agreements and make sure that your subscription covers the backup and recovery strategies.


Here comes the development – building the core features and creating scalable software architecture. The custom SaaS development process always goes along with testing. One of the often-used approaches is A/B tests to evaluate the performance and iteration. You couldn’t exclude testing as it enables the overall functionality.


This phase is exceptionally important for deploying all the operations. They should correspond to the level agreements, security, compliance and shared infrastructure of the cloud services. It has to cover the specifications of the previous stages that have already outlined the ways of service deployment in production.


When learning how to develop a SaaS application, remember that you need to deliver some value. It should introduce the concept that is relevant to the needs of the targeted audience. As a rule, this type of application includes functional tools, management of the account, analytics, etc. All these features should be collected and presented as one attractive and functional application. Simple and clear navigation, the user-centered design will help to make a good impression on your customers. Their dashboard shouldn’t be overloaded with unnecessary features. It’s true that the app has to include as much functionality as possible however the customers won’t be pleased with confusing and pointless interaction within it. 

For example, you want to create a SaaS application for content collaboration that helps to organize the business data. It could include document management, file sharing, search engines, communication channels, etc. Like any other application, you can start with the simple SaaS features and add the advanced ones gradually. Do your best to make the registration quick and simple. The users have to be provided with effective and fast ways of collaboration. The file-sharing feature has to include share, view, edit, comment options. The search engine is required for sorting files and also provides quick access to them. Some advanced collaboration applications could include inbuild tools for communication like live chats, voice calls, videos, etc. In short, this model is an ideal solution for delivering complex functionality. The point is that more advanced features should be presented to the users gradually as they move through their learning curve and get familiar with basic actions.


This model is widely applied and newcomers can learn how to develop a SaaS product from the success stories of numerous companies like SFDC or HubSpot. In general, all of them are leveraging the same tactics developed over the years of the market presence. We have gathered some of those SaaS development best practices in the list below:

  • Scalability – The main advantage of these apps is adding capacity. Handle both vertical (limited by the size of the server) and horizontal scaling (building the logical unit that works on different hardware and software). 
  • In-app support – Due to the data the applications deal with, they are rather complex ones. Therefore the users’ support could be delivered via the detailed tutorials, live chats, etc.
  • Omnichannel approach – it is the support strategy that will unify the customers’ requests and keep records of the previous interactions to simplify the coming ones.
  • Data protection – No SaaS product development can be completed without data encryption. Try to find all the possible ways to guarantee a high level of security. 
  • Frequent updates with greater value – Customers have to benefit from using your application. You should understand your users’ requirements and keep improving on a regular basis to deliver the best app functionality.
  • Integration strategy – It is common that companies migrate from one to another app or use a few of them at the same time. So it might be essential to exchange data and support interoperation between them. 
  • Service fees – The customers are choosing this approach not only for convenience and provided features, but they have found it money-saving. Instead of paying for installation and following updates, they favor the subscription approach.

Cloud platforms for hosting and maintenance

The majority of SaaS companies use third-party providers for the hosting of their products. On-premise hosting would be extremely expensive in their case not to mention a tremendous cost of developing anything close to Amazon’s platform for cloud management. Cloud platforms like Azure, Google Cloud, AWS, Heroku, and others offer a wide choice in terms of hardware, supporting software, and DevOps tools for those who want to build a SaaS app or migrate to the cloud.

To give you some examples of their distinctions, AWS was among the first market representatives. This platform offers flexible, fast, and reliable solutions for any type of application in the cloud.

Consequently, its structure consists of the project manager, cloud solutions architect, back-end and front-end developers, UI/UX designers, QAs, administrators and DevOps specialists. Collaboration and performing the tasks properly will deliver a successful market product. 

Cloud solution architect maps the architecture of the web application to ensure stability, performance, security, proper load balancing, nodes distribution, etc. The project manager is responsible for planning and estimation details as well as management of the overall SaaS development process together with a system architect. It is obvious that back-end developers deal with the server side, while front-end developers handle the user side.

Take into account the number of developers required for your project as it is common to set small back-end and front-end teams that have a few members. For example, you can hire the senior developer for complicated tasks whereas the junior specialist will be a great assistant to deal with regular ones. Hiring the professional UI/UX designer is also a key to success since front-end developers will implement the provided design.
