Banks today operate in an environment of constant change—technological, regulatory, and business-related. They introduce new products, respond to competitors’ moves, and meet growing customer expectations regarding innovation and service speed. As a result, IT systems must be continuously developed.
At the same time, IT architecture in banks is becoming increasingly complex. A single application rarely constitutes an entire system. More often, it is a set of multiple technologies and complex integrations of components that process data across various process paths.
This creates numerous challenges for IT departments. The cost of building dedicated solutions is rising, driven both by increasing system complexity and the high level of specialization among IT professionals. Technology projects are also becoming harder to predict: their budgets and timelines often exceed initial assumptions.
Banks are also processing ever-growing volumes of data, which requires efficient and scalable systems. In such conditions, even a minor change in an existing application can generate high costs and involve multiple technology teams.
As a result, many organizations still rely on a large number of small or medium-sized business processes performed manually. Automating them would make business sense, but in the traditional software development model it often proves too costly or too time-consuming. This creates a clear gap: the pace of change in business processes today exceeds the ability of IT organizations to build and modify systems using traditional development approaches.
Low-code technology as a response to development challenges
In recent years, low-code platforms have played an increasingly important role in the development of banking systems. Solutions of this type, such as the platform VSoft archITekt, enable the design of process applications within a single environment. Within such a platform, it is possible to create data models, business logic, workflow processes, user interfaces, and integrations with other systems.
This approach significantly reduces the cost of building systems, particularly in terms of team workload and overall project costs.
Another important advantage is the ability to rapidly prototype solutions and implement them incrementally. This allows banks to validate business ideas more quickly and reduce project risk.
Low-code platforms also make better use of existing teams. Not only developers, but also business analysts and system architects can be involved in application design.
Automation of banking processes
One of the most important applications of low-code platforms in banking is the automation of business processes. Many banks operate a large number of processes supporting their day-to-day operations, including application handling, document management, customer monitoring, and collateral management.
Automating such processes using traditional development models is often difficult due to cost and time constraints. However, low-code platforms make it possible to implement systems supporting even smaller or auxiliary business processes.
Processes can be modeled using workflow diagrams that define successive processing stages and the roles of participants. Some steps can be executed automatically by the system, while others are performed by users.
The system can respond to various events—for example, data entered into a form, signals from other systems, or the passage of time. It is also possible to run parallel processing paths.
This makes it possible to reflect even very complex operational processes functioning in financial institutions.
Building process applications – from backend to user interface
Applications supporting banking processes combine business logic with user interfaces. A key role is played by process forms, which serve as the primary interface for interacting with the system. These forms enable data entry, validation, and dynamic adjustment of fields to the process context.
In more complex cases, forms may consist of multiple elements and support advanced operational workflows. Process applications must also provide convenient data handling, including case lists and data summaries that can be filtered, sorted, and customized to user needs.
Integration with other banking systems is another critical component. Process applications interact with core banking systems, data warehouses, analytical systems, and document management systems. They often need to process and transform data from multiple sources.
Performance is also crucial in banking environments. Operational systems frequently handle large volumes of data and execute complex operations within short timeframes.
Security cannot be overlooked either. Process applications must ensure access control, user activity logging, and the ability to monitor process execution. This is essential both from a regulatory perspective and for managing operational risk.
Therefore, building process applications in banking requires addressing several areas simultaneously: user interface design, system integration, efficient data processing, and security and process monitoring mechanisms.
Summary
The greatest challenge for modern financial institutions today is not access to technology, but the ability to rapidly implement changes in business processes.
Low-code platforms are transforming the way IT systems are built. They enable the design of complete process applications within a single environment—from data models and business logic, through system integrations, to user interfaces. As a result, banks can respond more quickly to regulatory and market changes and more effectively automate operational processes.
In practice, this means that low-code is becoming one of the key tools supporting the development of modern banking systems. Experience from our implementations in financial institutions demonstrates how this approach works in practice. Selected examples are described in case studies available on the VSoft website.
