Business Transactions and Source Documents
The accounting process begins with identifying business transactions and gathering the necessary evidence to record them.
A business transaction is an exchange of economic consideration between parties that has a two-fold effect on the accounts of the business. Every transaction involves a 'give and take' aspect. For example, purchasing a computer for 35,000 involves giving cash and taking delivery of the computer. These exchanges are the raw data for accounting systems.
To ensure accuracy and legal validity, every transaction must be evidenced by a source document. Common source documents include cash memos, invoices, sales bills, pay-in-slips, cheques, and salary slips. These documents provide the objective evidence required for recording transactions in the books of account.
In cases where no external documentary evidence exists, such as for petty expenses, an internal voucher is prepared. These vouchers are arranged chronologically, serially numbered, and filed. They serve as the primary basis for all entries made in the accounting books.

Preparation of Accounting Vouchers
Vouchers are internal documents that specify which accounts are to be debited and credited for a particular transaction.
Accounting vouchers are classified based on the nature of the transaction. A 'Transaction Voucher' is used for simple transactions involving one debit and one credit. When a transaction involves multiple debits or credits against a single credit or debit, it is called a 'Compound Voucher'. These are further divided into Debit Vouchers and Credit Vouchers.
Complex transactions, which involve multiple debits and multiple credits, are recorded using a 'Complex Voucher' or 'Journal Voucher'. While there is no universal format, an effective voucher must include the firm's name, the date of the transaction, a serial number, the account titles, the amounts in figures, and a brief narration.
Vouchers must be signed by both the person who prepared them and an authorized official. They are essential for audit purposes and tax assessments, providing a clear trail from the source document to the final ledger entry.

The Accounting Equation
The accounting equation is the mathematical expression of the fundamental relationship between assets, liabilities, and capital.
The accounting equation states that the total assets of a business are always equal to the sum of its liabilities and capital. This is expressed as: Assets (A) = Liabilities (L) + Capital (C). This equation is also known as the Balance Sheet Equation because it represents the two sides of a balance sheet.
Assets represent the resources owned by the business, while liabilities and capital represent the claims against those resources. Liabilities are claims of outsiders (creditors), and capital is the claim of the owner (proprietor). Any change in one component of the equation must be balanced by an equal change in another component or a combination of components.
Profits earned by the business increase the owner's capital, while losses and drawings (withdrawals for personal use) decrease it. Regardless of the number of transactions, the equality of the equation remains intact, reflecting the dual aspect of every transaction.
Effect of Asset Purchase on the Equation
Assets (Cash -10,000 + Machinery +1,25,000) = Liabilities (Creditors +1,15,000) + Capital (No Change)
Rohit buys machinery for 1,25,000, paying 10,000 in cash and the rest on credit. Cash decreases by 10,000, Machinery increases by 1,25,000 (Net Asset increase of 1,15,000), and Liabilities (Creditors) increase by 1,15,000. Capital remains unchanged at its previous balance (e.g., 5,00,000). The equation remains balanced: 6,15,000 = 1,15,000 + 5,00,000.

Rules of Debit and Credit
Accounting uses the terms 'Debit' (Dr.) and 'Credit' (Cr.) to record increases and decreases in different types of accounts.
In accounting, an account is often represented in a 'T' shape, with the left side called the Debit side and the right side called the Credit side. The rules for recording transactions depend on the classification of the account into five categories: Assets, Liabilities, Capital, Expenses/Losses, and Revenues/Gains.
For Assets and Expenses/Losses, an increase is recorded on the Debit side, and a decrease is recorded on the Credit side. Conversely, for Liabilities, Capital, and Revenues/Gains, an increase is recorded on the Credit side, and a decrease is recorded on the Debit side.
This system ensures that for every transaction, the total amount debited equals the total amount credited. This is the core principle of the double-entry system of bookkeeping.
| Account Category | Debit (Dr.) | Credit (Cr.) |
|---|---|---|
| Assets | Increase | Decrease |
| Expenses / Losses | Increase | Decrease |
| Liabilities | Decrease | Increase |
| Capital | Decrease | Increase |
| Revenues / Gains | Decrease | Increase |

The Journal: Book of Original Entry
The Journal is the first book where transactions are recorded chronologically before being transferred to the ledger.
Journalizing is the process of recording transactions in the Journal. Each entry includes the date, the accounts to be debited and credited, the amounts, and a brief explanation called a 'Narration'. The Journal provides a complete historical record of all transactions in one place.
A 'Simple Journal Entry' involves only two accounts—one debit and one credit. A 'Compound Journal Entry' involves more than two accounts, such as when a single payment covers multiple expenses or when an asset is purchased with both cash and credit.
The Journal is often subdivided into special journals for efficiency in larger businesses. These include the Cash Book, Purchases Book, Sales Book, and others. Transactions that do not fit into these special books are recorded in the 'Journal Proper'.
Recording a Credit Purchase
Purchases A/c Dr. 30,000 To Govind Traders A/c 30,000
When goods are purchased on credit, the Purchases account (an expense) increases and is debited. The Creditor's account (a liability) also increases and is credited.

The Ledger and Posting Process
The Ledger is the principal book of accounts where transactions are classified and summarized by account title.
While the Journal records transactions chronologically, the Ledger organizes them analytically. Each account has its own page or section in the Ledger. The process of transferring entries from the Journal to the Ledger is called 'Posting'.
To post a debit entry, you locate the account in the Ledger, enter the date on the debit side, and write the name of the corresponding credit account in the particulars column. The page number of the Journal is recorded in the 'Journal Folio' (J.F.) column. The same process is followed for credit entries on the right side of the account.
The Ledger is vital for management because it allows them to see the net balance of any specific account at any time, such as how much is owed by a specific customer or the total value of office equipment owned.
| Basis of Comparison | Journal | Ledger |
|---|---|---|
| Nature of Book | Book of Original Entry | Principal Book |
| Record Type | Chronological Record | Analytical Record |
| Process Name | Journalizing | Posting |

Accounting for Goods and Services Tax (GST)
GST is an indirect tax levied on the supply of goods and services, requiring specific accounting entries for inputs and outputs.
When a business purchases goods or services, it pays GST, which is recorded as 'Input GST'. This is an asset because it can be set off against the GST the business collects from its own sales. When the business sells goods or services, it collects 'Output GST', which is a liability until paid to the government.
GST is categorized into CGST (Central GST) and SGST (State GST) for transactions within a state, and IGST (Integrated GST) for transactions between states. The rules of debit and credit apply: Input GST (Asset) is debited when paid, and Output GST (Liability) is credited when collected.
At the end of a period, the business 'sets off' the Input GST against the Output GST. If Output GST exceeds Input GST, the balance is paid to the government. If Input GST is higher, the balance is carried forward as an 'Input Tax Credit'.
GST Calculation and Journal Entry
Purchases A/c Dr. 1,00,000; Input CGST A/c Dr. 5,000; Input SGST A/c Dr. 5,000 To Creditors A/c 1,10,000
For a purchase of 1,00,000 with 5% CGST and 5% SGST, the tax amounts (5,000 each) are debited as they represent a future tax credit (Asset). The total liability to the supplier (Creditors) is 1,10,000, representing the sum of the purchase price and the taxes paid.

Classification and Utility of Ledger Accounts
Ledger accounts are classified to facilitate the preparation of financial statements like the Profit and Loss Account and the Balance Sheet.
Ledger accounts are broadly classified into 'Permanent Accounts' and 'Temporary Accounts'. Permanent accounts include Assets, Liabilities, and Capital; their balances are carried forward to the next accounting year and appear in the Balance Sheet. Temporary accounts include Revenues and Expenses, which are closed at the end of the year by transferring them to the Trading and Profit and Loss Account.
The utility of the ledger lies in its ability to provide condensed information. While a journal might have hundreds of entries for 'Cash' scattered across many pages, the Cash Account in the ledger brings them all together to show the actual cash on hand.
In modern computerized accounting, while the physical 'book' may not exist, the logic of the ledger remains the same. Transactions are coded and automatically posted to the relevant account heads, ensuring real-time updates to the financial position of the firm.
