Where to start

A quick map of the Fundamentals tab — two plain-language series, Core Banking and Accounting, and which one to read first for what you want to learn.

The Fundamentals tab is where you build intuition before touching anything Lerian-specific. It holds two short, plain-language series that build a foundation for core banking from two angles: accounting explains trustworthy financial records, while Core Banking explains how a complete banking platform applies them.

Accounting

Explains the language underneath it: assets, liabilities, debits, credits, and how the books stay balanced.

Core Banking

Explains a complete core banking platform: its ledger foundation, accounts, balances, value movement, customer identity, reporting, and auditability.

They sit side by side because they answer different questions. One shows you the machine; the other shows you the grammar that machine is built on.

Which one first
