Core Banking

The heart of any bank is its core banking software
It’s a primary general ledger designed for critical banking operations. Such systems act as golden sources of data related to clients, sales, risks, general decisions. With these tools, employees and end-users can open and close accounts, process payments, make transfers, handle deposits and withdrawals.
If you want to get advanced and modern core banking
we’re ready to help. McKinsey reports that 70% of banks are currently reviewing their core banking systems. They wish to optimize processes, upgrade legacy apps, rebuild core architecture to innovate faster and deliver better services. Sounds like your goals? We’re sharing these values and can assist in your digital transformation.

How We Deliver the Services

Depending on the needs of your business, we can use one of three implementation approaches. The starting phases are often similar. It’s possible to develop a custom solution, upgrade your existing legacy platform, change one module or the entire system.
The general flow remains unchanged almost always:
  1.  Pre-project assessment.
  2.  Discovery.
  3.  Engineering.
  4.  Quality assurance.
  5.  Deployment.
  6.  Operation and support.
  • Inventory of current implementation.
  • High-level architecture documentation.
  • Low-level architecture documentation.
  • Service line analysis.
  • SLA/OLA and metrics agreements.
  • System configuration monitoring.
  • Metrics updates.
  • Definition of AS IS state.
  • Definition of TO BE state.
When it comes to implementation, there are three classic approaches to core replacement.

Big Bang

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 systems 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For banks that want to: urgently replace an outdated core.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.


This approach is highly popular among banks. With it, you can keep your legacy core banking software 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.


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.

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.

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.

What We Need from Your Side

Usually, banks have strong IT services. They understand what’s needed for core banking software 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.


Generally, there are three aspects of your responsibilities:


  • Business: define project success criteria, coordinate the flow of business needs, provide business feedback that is crucial for the success of any project.
  • IT: keep infrastructure, licenses, and third-party modules or services, coordinate general schedule if the dedicated PMO structure isn’t presented.
  • Vendor management: coordinate all involved parties on contract level, control budget execution, monitor risks related to major cross-vendor project phases.
