Bookkeeping

What is bookkeeping?

Bookkeeping is the systematic recording, classifying, and organising of a business's financial transactions in its books of account. It captures every purchase, sale, receipt, and payment in chronological order.

Bookkeeping is the foundation of the accounting cycle. It covers day-to-day entries into journals, ledgers, and subsidiary books. This data feeds financial statements, tax returns, and management reports.

Why is bookkeeping important?

Bookkeeping gives a business an accurate, up-to-date picture of its financial position. Without it, owners cannot track cash flow, measure profitability, or prove income and expenses during audits and GST assessments.

Reliable books also build trust with stakeholders. Banks, investors, and tax authorities rely on them to assess creditworthiness and verify returns. Auditors use them to detect errors, prevent fraud, and confirm statutory compliance.

How does bookkeeping work?

1. Transactions are identified

Every financial event (a sale, purchase, receipt, or payment) is recognised as a business transaction. Each one must have supporting evidence like an invoice, bill, or bank statement.

2. Entries are recorded in the journal

Each transaction is entered in the journal in chronological order. The double-entry system is used, with equal debit and credit amounts to keep the books balanced.

3. Entries are posted to the ledger

Journal entries are transferred to individual ledger accounts such as cash, sales, debtors, creditors, and GST payable. Balances then build up account by account.

4. A trial balance is prepared

At period-end, all ledger balances are listed in a trial balance. Total debits must equal total credits; any mismatch signals a posting error to investigate.

5. Books are closed, and reports are generated

Once the trial balance tallies, the data flows into the profit and loss account, balance sheet, and GST returns.

Example

A furniture wholesaler in Coimbatore records transactions across one week. On Monday, the business buys teakwood worth ₹1,50,000 from a supplier on credit. The bookkeeper debits Purchases ₹1,50,000 and credits the supplier's account.

On Wednesday, the wholesaler sells finished tables to a retailer for ₹2,20,000 plus 18% GST, received by NEFT. The bookkeeper debits Bank ₹2,59,600, credits Sales ₹2,20,000, and credits Output GST ₹39,600. On Friday, ₹40,000 is paid towards salaries: Salary Expense is debited and Bank is credited.

By month-end, these entries flow into the ledger, trial balance, GSTR-1, and profit and loss account. The wholesaler can then see turnover, GST liability, and net profit at a glance.

Key points to remember

• Bookkeeping is the systematic recording of financial transactions in books of account and precedes the wider accounting cycle.
• It follows the double-entry system, where every transaction has an equal debit and credit.
• Common books maintained include the journal, cash book, purchase book, sales book, and general ledger.
• Bookkeeping data forms the basis for the trial balance, financial statements, GST returns, and income tax computation.
• Businesses may use single-entry bookkeeping for very small operations and double-entry bookkeeping for accurate, standardised records.
• Accurate bookkeeping is essential for audits, tax assessments, and statutory compliance under Indian law.
