In one minute

What it is

The system of record for money: accounts, sub-accounts, postings, balances and the product rules — interest, fees, limits — that sit under a banking, wallet or lending product.

What you get

A double-entry ledger, product configuration, interest and fee engines, APIs and events, reporting and audit trails.

What you still own

Product design, integrations with payments and cards, operations, and — for licensed firms — regulatory accountability for the system.

When you need it

When a provider's built-in ledger no longer fits your products, when you hold your own licence, or when you need to replace a legacy core.

How it works

A ledger records money; a core banking system adds products, customers and operations. Some firms run a modern ledger next to a legacy core and move products across over time.

What to compare

Ledger correctness

Money must always balance

Ask: How are double entry, idempotency and immutability guaranteed?

Product configurability

Speed of launching products

Ask: Which products are configurable without code — savings, current, loans?

Performance

Growth and peak loads

Ask: What throughput and latency are proven in production?

Deployment and residency

Regulatory and control needs

Ask: Which deployment models and regions?

Integrations

Payments and cards must connect

Ask: Which processors and rails are pre-integrated; which events are published?

Multi-entity and currency

Expansion

Ask: Several entities, currencies and jurisdictions in one instance?

Migration support

Replacing a core is the hard part

Ask: Tools, methods and references for migration?

Upgrades

Staying current

Ask: Release cadence and how upgrades affect your extensions

Resilience and exit

Regulated outsourcing

Ask: Availability, recovery objectives, data export, exit support

How providers charge

Licence or subscription
