The Fundamentals section of Start Here 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. 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. Core Banking shows you the machine. Accounting shows you the grammar behind it.

Which one first


If you’re unsure, start with Accounting. The vocabulary it teaches makes everything in Core Banking (and the rest of the docs) easier to follow.
