Core banking systems

What we offer

You can get various core banking services: design, development, deployment, optimization, upgrade, and support of any core banking tool or functional module. Often, we work with legacy platforms that banks want to update or change. These outdated systems lead to exorbitant IT spending related to manual, inefficient processing, poor time to market, lack of personalization and integrations.

Modern digital tools can solve these challenges. Get your old app replaced with a universal solution for automated processing, efficient data storing, analysis, high-level customer support, and omnichannel delivery. As well, new core banking and financial services provide 360-degree client views, regulatory compliance, and reliable IT security measures.

Benefits of core banking transformation

Don’t miss your chance to gain a competitive edge by upgrading or transforming your core banking system. Main differentiators that you can get from a new or upgraded core banking software include the benefits below.

Cloud-native architecture

Decreases running costs, enables automation, and boosts resilience. We can use different cloud providers, including your private ones.


Available thanks to a wide range of various services. It allows banks to meet the needs of all clients, improve time to market.

Micro-services and API protocols

Facilitate third-party integrations, help banks to scale better. This tech also decreases the cost of core banking software development.

Real-time data processing

Provide advanced analytical capabilities. Thanks to optimized core data warehouses, businesses can access info much faster.

Our core banking solutions and approaches

Depending on the needs of your business, we can use one of three implementation approaches: Big Bang, Progressive, or Greenfield. The starting phases are often similar. It’s possible to develop a custom tool, upgrade your existing legacy platform, change one module or the entire system. But the general flow remains unchanged for all core banking solutions: pre-project assessment, discovery, engineering, quality assurance, deployment, operation and support.

Big Bang approach

Suitable for banks that want to change all at once, urgently. Based on the monolithic upgrade strategy, Big Bang may occur once in a few years. Through this approach, we complete extensive data migration, a major redesign, replacement of nearly all CBS for all branches. Thus, it’s possible to switch to modern core banking solutions fully but with significant risks. For banks that want to: urgently replace an outdated core. Risk: high. Speed: low.

Progressive approach

This approach is highly popular among banks. With it, you can keep your legacy core banking options but replace it step-by-step. We add new functions and upgrade modules iteratively using the “strangler pattern” that provides for rebuilding the most demanded functions via microservices. Hence, you get new features but can keep and reuse the existing code base. For banks that want to: innovate without extra risks. Risk: low. Speed: medium.

Greenfield approach

Based on the cloud-native architecture, the greenfield optimization of core banking solutions focuses on customers. According to it, new clients can use the updated systems while existing ones migrate slowly through re-enrollment. It means that you can test new solutions without risking your client base. This option combines safety, speed, and cost-efficiency. For banks that want to: experiment with tech safely. Risk: medium. Speed: high.

The discovery phase includes the following: inventory of current implementation, high-level and low-level architecture documentation, service line analysis, SLA/OLA and metrics agreements, system configuration monitoring, metrics. When it comes to implementation, there are three classic approaches to core banking replacement, development, or upgrade.

What impacts your project duration

The average project time depends on the size (number of accounts in your bank) and scope (number and complexity of modules or interfaces required). For new implementations, this timeline varies from 6 months to 3 years. Migration and upgrade projects also depend on the number of accounts, products such as loans or deposits, as well as infrastructure readiness. Depending on the chosen approach, these projects also can take from 6 to 36 months.

  • Project requirements
  • Expected deadlines
  • Team composition
  • Chosen technology and platforms

What affects your project costs

The total cost usually depends on the costs of software and services. The first aspect varies from vendor to vendor. For instance, Oracle, Finastra, and Temenos have different software fees. The availability of vendor support matters a lot, too. Services depend on size, scope, and schedule. The most essential factors include the complexity of integrations, localization requirements, local central bank requirements, migration strategy, the readiness of third-party services, EOD/EOM procedures, IT support, and change requests.

  • Project scope and complexity
  • Chosen technology
  • Project completion urgency
  • Engagement model: Fixed Price, Time and Material, Dedicated Team

What we need from your side

Usually, banks have strong IT services. They understand what’s needed for an automated banking system implementation, migration, or upgrade. Business users also know project acceptance criteria based on the scope and other parameters. To provide the most tailored services, we will need some info from your side: available business and tech documents, access to Jira/Confluence, description of current models, SLAs and OLAs, examples of issues and audit logs, target goals.

  • Project goals, vision, and roadmap if exist
  • High-level project requirements
  • Project-specific documentation if available, for example, a test strategy or test cases
  • Client’s availability (a couple of hours per week for requirements gathering sessions)
  • Project deadlines
