What is Double-Entry Bookkeeping?

Double-Entry Bookkeeping is the fundamental system of accounting used by all businesses. It is based on the principle that every financial transaction has equal and opposite effects in at least two different accounts. This system is built upon the accounting equation: Assets = Liabilities + Equity.

For Startups: Adhering to the double-entry system is a legal requirement and the only way to produce accurate, reliable financial statements. It provides a self-checking mechanism; if the books don't balance, it means an error has been made. All modern accounting software is built on this principle, making it easier for startups to maintain compliant records.

Example: When a startup buys a laptop for ₹1 Lakh in cash, it records a ₹1 Lakh increase in its Equipment (Asset) account and a ₹1 Lakh decrease in its Cash (Asset) account. The equation remains in balance.
