Introduction

Every financial report you see is built on a set of rules. These rules are called accounting principles, and they ensure consistency, accuracy, and transparency in financial reporting.

Accounting principles are standard guidelines used to record and report financial transactions.

In simple words: they are the “rules of accounting” that keep financial data reliable.
