Double entry system in Accounting

The double-entry system is the record of every business transaction which has two fold aspects & effects two accounts i.e., Debit or Credit. It means receiving value on one hand (debit) and giving the value on the other hand (credit). The double-entry system is used to record entry in the journal.
It is also called Dual Entity System because in this every transaction has two parts or accounts: one account gives the benefit and the other receives it. The account which receives the benefit is debited or the account which gives the benefit is credited. The debit is recorded on the left side of the ledger while credit is recorded on the right side of the ledger. If the accounts are recorded in a double-entry system they would have two aspects one is debit and the other is credit. The debit is denoted by dr whereas credit is denoted by cr.

The two facts involved in accounting which results in a double-entry system are:

  1. the total transaction has been made
  2. reasons for making a transaction.

The double-entry system explains to us that for every debit there is corresponding credit for an equal amount of money while for every credit there is the corresponding debit for an equal amount of money.

Example of Double-Entry System: A business purchases goods for cash Rs 4,000/-. So, here;

Debit = goods (4,000)

Credit = 4,000

Synonyms of double-entry system

Double-entity system, double-entry bookkeeping, double inlet, double feed, double entries, double-stranded part


The accounting process is based on the three rules which are separated to each other by the three classes of accounts:-

According to these rules:

1. Personal account: This rule said that if a person or institution who receives a benefit is to be debited whereas if a person or institution who gives a benefit is to be credited.


Debit the receiver


Credit the giver

2. Real or Asset account: This rule said that an asset that comes to the business by the transaction is to be debited whereas the asset that goes out of the business by the transaction is to be credited.


Debit what comes in


Credit what goes out

3. Nominal, income & expenditure account: Account which is related to the expenses and loses is to be debited whereas the account which is related to the income and gains is to be credited.


Debit all expenses and loses


Credit all incomes and gains


There are five elements in accounting;

  • Assets
  • Expenses
  • Liabilities
  • Income
  • Capital

For every transaction, these elements are changed i.e. someone increases and someone decreases.

Example: Sold goods for cash 3,2000. So, here

Cash account Sales account

Here, cash is debited or increased while goods are credited or decreased by the same amount.

  • Assets increases debited – assets decreases credited.
  • Expenses increases debited – expenses decrease credited.
  • Liabilities decreases debited – liabilities increases credited.
  • Income decreases debited – income increases credited.
  • Capital decreases debit – capital increases credited.

The accounting equation is the founder of the double-entry bookkeeping system. This equation said that total assets are equal to the total liabilities & capital. It is one of the main feature of the Double Entry System that the total of debit is always equal to the total of credits.

i.e. Total Debit = Total credit

The accounting equation is displayed by the balance sheet.

In balance sheet the accounting equation is;

Total Assets = Total Liabilities + Capital

It means that at all times, the total of all assets must be equal to the total of all liabilities & owner’s capital.


Similarly, we can also record the transactions for the other accounting elements.

Let us have another example by preparing a trial sheet which proves that the total of debits is always equal to the total of credits.

Accounting equation gives rise to the balance sheet. Once the trial sheet is prepared then, it becomes easy to prepare a balance sheet and income statement of the business.


Accounting includes a process which has the sequence of procedures used to keep a record of what has happened in the organization and to report what financial effect of those things on the financial status of the organization.

The accounting process includes the following steps:-

  1. Transaction
  2. Analyze & Classify
  3. Journalize
  4. Posting
  5. Balancing
  6. Trial Balance
  7. Adjusting Entries
  8. Adjusted Trial Balance
  9. Closing Entries
  10. Financial Statements
  11. Post Closing
  • A step-by-step explanation of this procedure is:



Transaction means the exchange of money between two parties & this must be recorded in the organization’s accounting system. The exchange between two parties must be measurable in money.


Sometimes, the accounting department is not always available where the transaction takes place. So, it is very necessary to prepare a paper or computer record to keep track of daily transactions occurs.
Analyze means to examine something and then, explain & interpret it. It involves:

  1. What happened? At first, we will examine that – What kind of business took place? Did we charge our customers for something, get money for something, gave money to buy something.
  2. What accounts will change? We want to know about all the accounts individually (Assets, Expenses, Liability, Owner’s Equity) that what increases and what decreases. Any time when a transaction takes place, it affects two accounts or at least two accounts will change.
  3. How will they change? Will the account increases or decreases.
  4. Do they get a Debit or Credit? It is recorded in T-accounts that is it (transaction) debited or credited.
Journals are also called the “ book of original entry” because when any financial transaction occurs it is recorded in the journal in the first instance. Journal is a book where we kept the daily record of all the transactions occurs in the organization.
Posting is the process of transferring or post the information of the financial transactions in the journal to the appropriate accounts where they fall. Balancing is a process of adjusting the increases by adding the increases to and decreases by subtracting the decreases from the previous balance in an account.
Trial balance is the list of balances of all the ledger accounts. Debit balance is recorded in one column while a Credit balance is recorded in one column, then each column is totaled and compared which proves that Debit = Credit.


  • The Single-entry system involves an incomplete record of transactions while the Double-entry system involves complete recording of transactions.
  • The Single-entry system requires one-sided entry whereas in Double-entry system two-sided entries are required as every transaction affects two accounts.
  • Errors are hard to identify in the Single-entry system while Double-entry system errors are easy to locate.
  • The nature of Single-entry system is simple as compared to the Double-entry system as it is complex.
