Factors That Impact the Cost to Develop an App Like Santander

Moderate App$60,000 – $150,0006-12 months
Complex App$150,000 – $300,00012+ months

The complexity of the backend system, which handles data management, security, and integration with other banking systems, can also be a significant factor that affects the mobile banking app development cost.

Maintenance and Updates

Post-launch maintenance and regular updates to ensure the app remains compatible with new operating system versions and hardware add ongoing costs.

Hidden Factors Impacting the Cost to Develop an App Like Santander

While the direct costs associated with the development stages of a mobile banking app like Santander are significant, hidden factors can also impact the overall cost. These hidden factors often go overlooked in the initial budgeting but can have substantial financial implications as the project progresses. Let’s take a look at them below:

Hidden Factors That Impact the Overall Development Budget of App Like Santander

Change Requests and Scope Creep

You might want to add new features or change existing plans during the development process. This can lead to what is known as ‘scope creep,’ where the project grows beyond its original scope. Such expansions can increase the cost to create an app like Santander and delay the project’s timeline as additional resources are needed to accommodate the changes.

Integration with Existing Systems

Integrating the new app with existing banking systems, databases, or third-party services can be more complicated and expensive than anticipated. The compatibility between the latest app and existing systems can greatly affect the effort required to ensure they work seamlessly together, potentially increasing the cost to build a mobile banking app like Santander.

Regulatory Approval Delays

Obtaining the necessary regulatory approvals can take longer than expected. Any delays in the approval process can extend the project timeline and increase the costs to make an app like Santander. You might need to continue consulting with legal and compliance experts longer than planned.

Technology Licensing

Developing a mobile banking app requires specific technologies, often with licensing fees. These charges can be significant depending on the technologies chosen, and in many cases, these fees are recurring, adding to the overall cost to create an app like Santander.

Data Security and Compliance Adjustments

Banking apps must adhere to strict data security and regulatory standards, which can change. Keeping up with these changes might require additional adjustments, involving more work and possibly more money to ensure the app complies with the latest standards.

Testing and Quality Assurance Overruns

Ensuring that the app is secure and functions correctly without any bugs is crucial. However, thorough testing and quality assurance can take more time and resources than initially expected, especially if significant issues are found that need to be resolved, which can push the budget higher.

After looking into the major mobile banking app development cost factors, let’s move ahead and look into how businesses like yours can optimize the overall development budget.
