Oradian Custom Code: Configure your core system

The dynamic financial services landscape is pushing institutions to rapidly adapt to evolving customer demands. This has made a flexible, extensible core system more valuable than ever as firms seek to deliver to a growing market.

Oradian Custom Code allows financial institutions to integrate their logic seamlessly into their core system, providing unmatched control, flexibility, scalability, and speed in dynamic markets. This service moves beyond a one-size-fits-all solution, enabling customers to extend their core system’s capabilities to meet distinct needs through an extra degree of customisation.

What is Oradian Custom Code?

Oradian Custom Code is the next step in Oradian’s commitment to extensible banking, empowering users to introduce new processes to the system beyond basic low-code customisation. It helps eliminate the challenge of systems becoming complex and unwieldy due to numerous code changes, which can hinder growth. It achieves this through three core components:

External JARs (Java Archive files): These allow users to import JAR files to extend Instafin’s capabilities and create highly customised solutions. Customisation through external JARs is crucial for creating a truly extensible system, allowing users to write, upload, and execute code directly within the system.

This provides developers with access to the full domain model, allowing them to influence any part of the system and adjust existing processes in ways not typically supported. JARs can also extend API behaviour, introduce specialised daily or monthly processing, or customise specific behaviours like minimum balance requirements. For instance, one partner uses JARs to implement and provide definitions for calculating a fee, which is then used as part of a regular API, with the logic contained in a single location.

Formulas in dynamic reports: Users can define custom tags with specific expressions, leveraging a robust syntax with available operators and conditions, to take control of their reporting capabilities

Calculated expressions on custom fields/tables: Users can define specific expressions in custom fields and tables.

Popular use cases:

Specialised calculations: Easily implement product-specific requirements, such as applying a late fee of X if an account is overdue by more than X days.

Enhanced reporting: Create custom formulas and add unique data tags within Oradian’s advanced reporting system to generate insights that meet exact needs.

Building custom APIs: While Oradian offers a broad set of APIs, specific workflows may require a unique API. For example, users can build an API directly within the system to combine “create account” and “edit account” actions. JARs can also extend the behaviour of APIs.

Benefits of Oradian Custom Code

Oradian Custom Code allows financial institutions to adapt their core system rapidly to changing market conditions and customer demands. Its flexible coding and no-code options enable users to extend their core system’s capabilities for their specific business needs, offering:

Unlimited adaptability: Enables near-unlimited customisations, allowing the system to adapt to precise business needs and customer demands.

Tailored calculations: Implement calculations to match specific use cases.

Versatile functionality: Expand APIs with new commands for various purposes, enhancing API integrations.

Advanced reporting: While existing Dynamic Reports offer extensive business intelligence, Oradian Custom Code allows for tailoring formulas to unique reporting needs.

No-code configuration: Calculate expressions for capturing complex operations without low-level coding, ensuring alignment with their exact business requirements.

Oradian Custom Code enhances Instafin’s off-the-shelf capabilities with seamless upgrades and customisation options without code forking, allowing the system to be heavily customised to meet specific business demands. This commitment to extensible banking ensures customers have the tools to promote growth, boost performance, and effortlessly scale their core banking system.

Oradian Custom Code in action

As Salmon, an Oradian Custom Code user, noted, Oradian provides “the beauty of being a cloud-hosted, ready-made solution, but with our ability to develop it further using modern software development techniques. It makes it so much more future-proof in terms of how you build your IT organisation”.
