CORE BANKING

A Core You Configure, Not Rebuild

The system of record for accounts, products, fees, interest, limits and eligibility — governed through configuration rather than release cycles.

For accounts, products, pricing and rules

Parameter-driven products

Define account and product behaviour through parameters instead of bespoke development.

Fees, interest and limits

Pricing, accrual, charging and thresholds maintained by the business under approval controls.

Ledger integrity

Postings, balances, holds and reversals handled consistently across every channel.

Eligibility and rules

Who can hold what, on which terms, enforced centrally rather than per channel.

Maker-checker governance

Every configuration change is proposed, reviewed, approved and logged.

API-first

Every core operation is available as an API for internal and partner consumption.

Commercial change without an engineering queue

Most core replacement pain comes from a simple fact: commercial change requires code. Here, product definitions, fee structures, interest rules, limits and eligibility live in configuration with full audit history.

The result is a shorter path from a pricing decision to a live product, with the control evidence regulators expect.

  • Account and product definitions
  • Fee and interest structures
  • Limits and thresholds
  • Transaction rules
  • Approval workflows
  • Full change audit

Coexist or replace

Wrap selected layers around an existing estate and migrate progressively, or deploy as the full system of record. Deployment can be SaaS, your cloud, on-premise or in-country.
