SaaS Development Challenges – A Transformation From Custom Software

Have you ever thought about monetizing your custom software? In fact, many corporations have monetized their custom software by transforming it into SaaS products. It is called custom software SaaS transformation. Specifically, you have your custom software undergo technical adjustments to make it into a SaaS product. However, every transformation has its difficulties and so does custom software SaaS transformation. There are few notable SaaS product challenges in transition development. Let’s have a look at SaaS development challenges under a technician scope!

Driven Demand

The demand arises when custom software operates smoothly and brings so many positive results that owners want to share, advertise, and monetize their well-tailored business software to the market. This software transformation brings enormous profits for the economy and participating individuals or groups such as developers, investors, users, and especially the original custom software owners. On the market, in fact, there are many existing transformation software that you have used at least once.

Notable Custom SaaS Transformation


Founded in 2004, Facebook was initially created for Harvard students only. Facebook’s user target has widened rapidly since it has extended the usable age and spread to other North American universities in 2006. It was once recorded as the most downloaded app in the 2010s, with over 2.8 billion monthly active users. With the resounding success, Facebook is no longer a communication platform for Harvard students only but one of the most popular social networks globally.


AWS – Amazon Web Service, known as the most popular on-demand cloud computing platform, is a subsidiary of Amazon, initially was developed to support Amazon’s internal needs. Amazon monetized AWS by marketing to subscribers a valuable tool with a large scale of capacity, guaranteed security, and better affordability with its success beyond the expectation. Gradually, AWS has contributed huge revenue to Amazon over the years and accounted for 32% ~ $41.8 billion cloud market in the first quarter of 2021. In particular, starting around 2017, AWS has claimed more than 33% of all cloud, while Microsoft Azure and Google Cloud just had 18% and 9%, individually.


Initially, Custom SaaS transformation has a starting aim of advertising good features of a custom product to widen the accessibility to everyone who can benefit from it. The benefits which it has brought to the owners are undeniable. However, with the enormous profits, it has become more commercialized.

The Technology Market

After the transformation process completes, products are ready to serve your needs. Custom software SaaS transformation, in a word, is an advanced version of the usual Off-the-shelf solutions. It is more competitive, functional, and expensive than Off-the-shelf software. Furthermore, it provides positive competition and fosters constant innovation and development from technology developers.


It goes without saying that they have more options in finding the most suitable software for their business growth. Although price is a determining factor in any investing activities, the suitability and functionality of a product play a vital role in technology investment. SaaS transformation products offer a reasonable price with a shortening time in implementation. Furthermore, they have diverse functions, better interaction, and smooth speed, making them distinctive on the market. Last but not least, it offers the best user experience, especially the most suitable for start-ups.


It is a notable benefit since they can monetize and gain enormous revenue from their custom software, on which they have invested for their needs only. From end-users, they become a supplier. Let’s imagine how their position and scalability have enhanced when their transformation product is as popular as Facebook.

Technical challenges

Thanks to transforming from the base of a custom solution, the custom software SaaS transformation product inherits all advantages and unique features for a particular business. Therefore, it is more attractive and highly rated than other solutions on the market. However, to achieve these successes, it has to undergo a technical transformation. As a matter of fact, every upgrade has its difficulties, and so does the custom software SaaS transformation development.
In fact, the related SaaS product development challenges have been mentioned publicly on the Internet that you may easily come across, such as 5 Challenges Faced in Software Development Technology. Therefore, in this blog, we aim to dive deeper into some critical points.

Multi-tenant support

Multi-tenancyis one of the SaaS solution’s outstanding features. However, it is also a SaaS product development challenge for any technical transformation. Due to its independent requirement among various users, how they can live on the same service without being affected is a primary issue to cope with. In a word, the major matters are database management and resource sharing.
Furthermore, depending on the extent, you need a comprehensive solution for different customers’ autonomous data. In fact, it helps lessen changes in technique and technology.

Scaling plan

A scaling plan is the second SaaS product development challenge, which has interaction with multi-tenancy. In fact, we don’t know what the future has in store, so the ability to have foresight and initiative will foster efficient work. It is believed that a scaling strategy should include short and long-term visions due to its significant role in business growth.
Specifically, it would be best to focus on resolving a certain number of customers in the scaling plan in the short term. After that, for a long-term vision, your scaling system should be designed for better reconfiguration if an explosion of customers and users occurs.

Vertical scale

The vertical scale is a technical term for an upgraded configuration resource for a more significant customer pool. Let’s pull an example for better illustration.
E.g., Your server has only 8G RAM yet has double the number of customers. Therefore, a RAM 16G upgrade is a better choice for the development. In a word, vertical scale benefits your short-term vision when first launching.
With a closer look, vertical scale’s advantage is convenience. You can have your configuration upgraded by using turnkey without any effect on the database or operating structures. However, the vertical scale has its limit upgrade, and therefore, it isn’t the best choice for long-term development.

Horizontal scale

Unlike vertical scale, the horizontal scale is about resource expansion. In a word, instead of upgrading the configuration from 8G RAM to 16 G RAM – you install another 8G RAM server to adapt a double number of users. The feature that makes horizontal scale distinctive is the unlimited scale – as in theory.
Modern cloud systems have support in handling scaling logic and database sharding; however, it is a mandate that you grab the key of the changes to master the game. To clarify, all conditions must be predefined perfectly in advance; otherwise, it would be a significant challenge in the transition development.

Cloud platform

There is no need to run infrastructure operations such as AWS, GCP, or Azure on your own with cloud platforms. The cloud platform provides various support to your product operation in the most reliable and secured way.

CI/CD – Zero downtime deployment

It is crucial for you to upgrade the efficiency of automated build and test. Thanks to these automated testing environments, new releases are ready consistently and continuously. Furthermore, your product needs to acquire a Zero Downtime guarantee when it comes to the upper class.
However, it is crucial that you find a reliable software development partner to transform your custom software SaaS without interruptions and backward compatibility. Developing a successful custom software SaaS transformation requires an experienced technical team with experts that master in-depth levels of each detail of your application. In a word, a trustworthy and experienced IT team will have your SaaS product overcome challenges in transition development.


Besides dependence on service tools, monitoring is equipped with AWS, GCP, Azure. However, you should have your utilities and tools built for monitoring systems with a complex infrastructure service. It helps detect technical errors and provides solutions immediately.
