Accounting is the process of recording all financial transactions of a business over its lifetime. It is one of the most important and necessary functions for any business.

There are two major kinds of accounting. In this blog, we will discuss the single entry system of accounting. We will understand what exactly the single entry system is, its advantages, and why it is not as widely used as the double-entry system of accounting. 

What is Single Entry System

Let’s use the example of a fictional bakery to better understand this concept. 

Introducing: Razor Bakery. Our name is sharp, but our bread is soft! 🍞


Razor Bakery started out as a tiny bakery operated out of its owner’s home kitchen. At this initial stage, the owner – let’s call her Mrs. Pay – recorded Razor Bakery’s transactions roughly in a book of accounts called a cashbook. 

If she bought flour for Rs 400 on the 21st of October, she would record it in her cashbook as

Date Purchase Expense (Rs) Income (Rs)
21-Oct-2022 Flour 400


This is called the single entry system. This system of accounting is extremely simple – only payments and receipts are recorded. 

If Mrs. Pay earned Rs 700 from business on the 22nd of October, she would record it as –

Date Purchase Expense (Rs) Income (Rs)
21-Oct-2022 Flour 400
22-Oct-2022 Sales 700


Let’s now look at the advantages of the single entry system. 

Advantages of Single Entry System 

1. Economical

A major advantage of the single entry system is that it is economical, especially for businesses at earlier stages, where the founder also dons the hat of accountant. It does not require the services of a professional accountant, or expensive accounting software. All you need is a pen and a notebook. Maybe even an Excel sheet, if you’re feeling fancy. 

2. Simplicity

The reason many small businesses prefer using the single entry system is that it is simple. There are no major rules to follow, and anybody can do it – even people with no accounting knowledge. 

Unfortunately, this simplicity means that the single entry system has more disadvantages than advantages. 

Disadvantages of Single Entry System 

1. Incomplete records

It may seem like the purchase of flour has only one dimension – but this is not the case. Every transaction has two sides to it. 

The single entry system only records one side of the transaction. We can see from Mrs. Pay’s cashbook that she spent Rs. 400 on flour on the 21st of October, but we don’t know how she paid for it. 

2No scope for financial analysis

Looking at a cash book would give no insight into a business’s financial position, since it does not record the cash balance or amount owed to creditors at the end of the quarter.

To get this information, we would have to manually calculate the total amount spent on flour after poring through her entire cash book – inefficient and tedious.

The best way to know if you are improving is by comparing current performance with past performance, and the single entry system simply does not facilitate this. 

3. Unscientific and inconsistent

As mentioned before, the single entry system of accounting does not subscribe to a set of fixed rules and formats, unlike the double entry system of accounting. 

This means that every business has a different way of recording its transactions, making it impossible to compare performance across businesses. 

Thankfully, the double entry system of accounting addresses all these concerns and more. But what exactly is it? How does it work? Read our blog on Double Entry Accounting to understand in detail.
