SaaS vs. Custom-Built

Are you planning to go for Fintech app development? Are you having a tough time deciding which of the development approaches to choose between SaaS and custom-built solutions? The development approaches you choose also determine the cost to develop Fintech app. However, selecting the right approach is extremely important as it can considerably impact the success of your app. 

Considering certain factors, such as development time, cost-effectiveness, scalability, etc., can help make the appropriate choice. If you are still confused between SaaS and custom-built solutions, then you are at the right place! Here, we will discuss the cost factors in Fintech app development and the key factors to consider while making a choice. So, let's get started: 

Understanding SaaS (Software as a Service)

Software as a Service or SaaS refers to a cloud computing model that facilitates delivering software applications over the internet. Unlike conventional software installations, SaaS eliminates the need for users to download, install, and maintain apps on their devices. Instead, in this case, the users are able to access the software often on a subscription basis, primarily through a web browser.

Custom-Built Fintech Applications

Custom-built Fintech apps are software solutions that are mainly developed for a specific organization or business. Unlike off-the-shelf software, these apps are customized to cater to the unique needs and objectives of an organization.

Cost Factors in Fintech App Development

Breakdown of Cost Considerations for Both SaaS and Custom-Built Solutions


  • Subscription Costs: SaaS solutions often come with subscription fees, which are charged on an annual or monthly basis. It covers updates, usage, and support.

  • Integration Costs: You may have to incur extra costs based on the complexity of integration with prevailing systems.

  • Customization Fees: While SaaS is standardized, some of the providers are involved in providing customization options at an additional cost.

Custom-Built Solutions:

  • Development Costs: Custom Fintech app development typically incorporates upfront costs for coding, designing, and testing the application.

  • Maintenance Costs: Ongoing maintenance, support, and updates contribute to the overall cost of a custom-built solution.

  • Integration Costs: You may have to incur extra expenses for the integration of the tailored solution with the existing system.

Upfront Costs vs. Ongoing Expenses


  • Upfront Costs: SaaS solutions follow a subscription model, so these typically have lower initial costs. It means that, in this case, there is a spreading of expenses over time.

  • Ongoing Expenses: Annual or monthly subscription fees add to the ongoing operational expenses.


  • Upfront Costs: The upfront expenses of custom development are generally on the higher side. It is generally due to its development, design, and testing requirements.

  • Ongoing Expenses: Although the ongoing subscription fees are low, support, updates, and maintenance all contribute to ongoing operational costs.

Comparing Development Timeframes

Time Required for SaaS Implementation

  • Rapid Deployment: SaaS solutions typically offer a swifter implementation. It is because, in this case, the software is already developed and hosted. Businesses can promptly subscribe and begin utilizing the app.

Timeframes Associated with Custom Development Projects

  • Varied Timelines: The time needed for developing, testing, and deploying custom-built solutions is more. However, the timelines can differ depending on the specific business requirements and complexity of the app.

Scalability and Flexibility

Scalability Features in SaaS

  • Automatic Scaling: There are built-in scalability features incorporated in SaaS solutions. It lets businesses seamlessly scale their usage with the growth of their unique needs.

  • Resource Allocation: Cloud-based SaaS apps have the capability to allocate resources dynamically based on shifting demand.

Flexibility Advantages of Custom-Built Solutions

Security Implications of SaaS vs. Custom-Built Apps:

  • SaaS Security: SaaS providers are known for heavily investing in security measures. It includes regular audits, data encryption, and compliance certifications.

  • Custom-Built Security: In the case of custom-built solutions, security depends on the development practices and the measures implemented by the organization. Thereby, it helps in offering more control. Not only that, but it also places responsibility on the business for security measures.

User Experience and Customization

Impact of SaaS on User Experience

  • Consistency: SaaS is known for its standardized nature. So, it helps in offering a constant user experience across different organizations and users.

Customization Options in Custom-Built Fintech Apps

  • Tailored Experience: Custom-built solutions facilitate a highly customized user experience. So, it is customized as per the specific requirements and preferences of the business along with its users.

Total Cost of Ownership (TCO) Analysis

Calculating TCO for SaaS Solutions

  • Subscription Costs: TCO for SaaS typically entails subscription fees over the projected lifespan of the app.

  • Integration and Customization Costs: Sometimes, the extra costs associated with customization and integration may also add to TCO.

TCO Considerations for Custom-Built Fintech Applications

  • Development and Maintenance Costs: TCO for custom-built solutions generally encompasses ongoing maintenance, development, and potential customization costs.

  • Integration Costs: Integration of the custom solution with prevailing systems may also contribute to the overall TCO.

Choosing The Right Approach for Your Fintech App

Factors to Consider in Decision-Making

Here are certain factors that you should essentially take into consideration in this aspect:

  • Business Goals: The first and most important thing you need to do involves identifying your business's overarching goals and objectives. You should consider whether scalability, rapid deployment, or specific features can help accomplish these goals.

  • Budget Constraints: Another crucial factor involves accessing your budgetary constraints, both ongoing and upfront. You should consider whether a SaaS or a larger initial investment with potential long-term savings (custom-built) well-aligns with your financial resources.

  • Time-to-Market: You should consider the urgency of bringing your fintech application to market. If speed is your utmost priority, choosing a SaaS solution is a good idea as it may offer a faster deployment. On the other hand, custom development may take longer but offer tailored functionalities.

  • Scalability Requirements: You should also consider the growth trajectory of your business. If scalability is crucial to you, you should go for a custom-built solution, as it offers tailored scalability options.

  • User Experience Expectations: It is vital to get an idea about the user experience expectations of your targeted group of audience. SaaS may be ideal if consistency is essential and a standardized user experience is acceptable. 

Whereas custom development might be a preferable option for businesses that focus on offering a highly customizable and unique user experience.

In a Nutshell

Thus, the cost to develop Fintech app relies on all the factors mentioned above. Make sure to take these into consideration when selecting the best development approaches for your needs. However, both of these approaches come with their own set of advantages. So, the final decision depends on your unique situation and business goals.
