What is Double-Entry?
The double-entry is an accounting system to record a transaction in a minimum of two accounts and is based on a dual aspect i.e. Debit and Credit and this principle requires that for every debit there must be an equal and opposite credit in any transaction.
Explanation
Double-entry is the first step of accounting. To understand any accounting entry, one should know about this system. Each accounting transaction is recorded in a minimum of two accounts, one is a debit account, and another is a credit account. Also, the transaction should be balanced i.e.; the credit amount should be equal to the debit amount.
Features of Double Entry
- Two Parties: There are two parties involved, one is the receiver, and another is the giver. The receiving party is debited, and another party is credited. For example, A purchases goods from B, where A is a receiver party, and B is a giver party.
- Equal Effect: Each transaction should have an equal financial effect. The debit amount should be equal to the credit amount.
- Separate Legal Entity: This system of accounting records the transaction separate from its owners.
- Debit and Credit: There are two aspects for recording any transaction, Debit aspect, and Credit aspect.
Principle of Double Entry
Double-entry is based on a simple principle, that for every debit, there must be an equal and opposite credit. There should be at least two accounts involved in any transaction.
Debit Side = Credit Side
The double-entry is based on debit and credit accounts of the transaction. So, we need to understand what account kind debits and what credits.
There are three different types of accounts, Real, Personal and Nominal Accounts. Rules of recording the transactions are decided based on the type of account.

#1 – Real Accounts – Debit what comes in and Credit what goes out. Real accounts include Pant & Machinery, Buildings, Furniture, or any other Asset account. So when we purchase Machinery, Machinery account is debited and when we sell Machinery, Machinery account is credited.
#2 – Personal Accounts – Debit the Receiver and Credit the Giver. The personal account includes the account of any person like an owner, debtor, creditor, etc. When we make payment to our creditors, the receiver account is debited, and when we receive the payment, then the giver account is credited.
#3 – Nominal Accounts – Debit all Expenses and Losses and Credit all Incomes and Gains. Nominal accounts include all the Expense, Income, Profit, and Loss accounts. For example, the Salary Paid account is debited, and the rent received account is credited.

A Limited makes a payment for the Goods next Month.
A Limited Purchases Machinery worth $30,000 by paying cash:
A Limited received Rent on Building $1,500:
