Subsidiary Books

The accounting process starts with the identification of transactions of financial and non-financial nature. All financial transactions are first recorded in Journal. This is known as Books of Original Entry. A small business has a lesser number of transactions and therefore, it is possible to record all business transactions in one book i.e. Journal. However, when business grows, the number of business transactions also increases. It is a very time-consuming, difficult, and tedious task for a firm to record such voluminous transactions and events in one single book. Thus, in order to save time and effort, it is advisable to subdivide the Journal into Subsidiary Books to record the transactions of similar nature in a separate book.

These sub-divided Journals are popularly known as Subsidiary Books. These books are also termed as Special Purpose Books or Special Journals or Books of Original/Primary/Prime Entry. Sub-division of Journal provides scope for division of work which leads to the improvement in efficiency and effectiveness. In other words, subsidiary books provide ease and convenience to record transactions of similar nature in a separate book. Journal entry is not required for the transactions which are entered in these books.

Quick and Efficient Recording: When the size of a business is large, then definitely its number of business transactions will also be high. It is a very tedious and time-consuming process to record all the transactions in a Journal. By maintaining separate books, then recording of such voluminous transactions can be done in lesser time and more efficiently. So, due to this reason, the need for maintaining special purpose books arises.

Similar Nature: In every business organization, there are various transactions that are similar and repetitive in nature. It will be more convenient to record all similar transactions in one place as it helps in the division of work among the employees. Thus, this need can be fulfilled by preparing the special purpose books.
