The double-entry accounting system was never designed to make recording easy. Instead, it was designed with checking in mind—to make checking quick, easy, and very reliable.

Why Use the Double Entry Accounting System

You could attempt to keep a business’s record of income and expenses by using a simple system.

Wages Purchases
The problem is a business makes many transactions—some of which are cash transactions — some of which are credit transactions—and all of these transactions are mixed together.
Cash Transactions Credit Transactions
This makes checking a simple system difficult and time consuming. Because of this, it’s easy to make mistakes, and if only some of these transactions are incorrect, your records will be rendered useless.

To overcome this problem, modern day accounting systems are based upon the double entry accounting system. This system is not only more reliable, but it is also much quicker and easier to check. With this system, you still record income and expenses.

But you record a duplicate copy of those transactions in other accounts, as well. As you do this, the system is cleverly designed to sort your duplicate record of transactions into homogenous groups of cash transactions and credit transactions.
Debtors Creditors Bank
Once sorted, the transactions shown in these other accounts are in a convenient format for checking against the records of other businesses, such as the bank statement and suppliers statements. If the duplicate record proves to be correct, it follows that your record of transactions shown in the income and expenses should be correct, as well.

Debits & Credits

When recording transactions with the double entry system, you always use two or more accounts. The reason for this is each transaction is deemed to have two sides: money or value comes from somewhere, and that money or value goes somewhere or is used somewhere.

For example, if you pay for telephone expense by check or electronic payment, you withdraw money from the bank and send it to the telephone company. To record this transaction, you would use an account called a checking account or a bank account to show where the money came from.

And you would use an account called a telephone expense account to show where the money was used or where it went.

Each account is also divided into two sides: a credit side and a debit side. The reason for this is sometimes money or value comes from an account, but at other times, it goes to that account. Take the bank account for example. Sometimes you withdraw money from the bank, but at other times, you deposit money into it.

With the double entry system, you overcome this problem by using debits and credits. If money or value has come from an account, you record the transaction amount on the credit side of the account.

In your bookkeeping or accounting course, these accounts are shown as Taccounts, and when you record transactions with T- accounts, you’re always showing a flow of money or value.

Presumably, the words credit and debit were chosen to signify which account is owed for the provision of money or value and which account owes for it. In other words, by using a credit entry, you signify that the account is owed for the provision of money or value.

Regardless of etymology, though, you use the same process to record each and every transaction the business makes no matter whether you’re recording a cash transaction or a credit transaction.

Recording a Loan Whenever you are required to record a cash transaction using debits and credits, begin by asking “where did the money or value come from and where did it go, or where was it used?” For example, suppose a business owner borrowed some money from a friend or relative to start a retail store. When they received the money, the business owner would deposit it in the business’s bank account. To record the deposit transaction, you would use an account known as a loan account and the bank account.

Recording Purchases You use the same process to record all transactions, and with cash transactions, you always update the bank account and one other account. For example, if the business owner buys goods to sell in the store and pays for those goods by check or electronic payment, they will withdraw money from the bank. To record the withdrawal transaction, you would use the bank account and an account known as a purchases account.

Recording Expenses To operate the store, the business owner will need to pay for various expenses. If paying by check or electronic payment, they will withdraw money from the bank. To record expense transactions, you use the bank account and the appropriate expense account.

Recording Sales You show the flow of money the same way regardless of whether you’re recording an expense transaction or an income transaction. For example, if the store owner sold some of the goods for cash, they would deposit the money in the bank. To record the deposit transaction, you would use an account known as a sales account and the bank account.

Checking Cash Transactions By month-end, you should have a complete record of cash transactions. You will have one record of sales and costs in accounts known as income and expense accounts.

Because the bank account contains a duplicate record of your cash income and expense transactions, you can check all of your income and expense accounts by checking the bank account, alone. You do this by checking your bank account against your business’s bank statement.
