Double entry system

Double entry system of book keeping is a scientific and complete system of recording the financial transactions of an organisation. According to this system, every transaction has a two fold effect.

The basic principle of double entry system is that for every debit there must be an equivalent and corresponding credit. Debit denotes an increase in assets or expenses or a decrease in liabilities, income or capital. Credit denotes an increase in liabilities, income or capital or a decrease in assets or expenses.


“Every transaction involving money or money’s worth has two fold aspects, the receiving of a value on the one hand and the giving of the same value on the other. This two fold nature in all transactions must be recorded in the books and this gives rise to the term Double Entry Book keeping”.- Munro and Palmer

“Every business transaction has a two-fold effect and that it affects two accounts in opposite directions and if a complete record is to be made of each such transaction it is necessary to debit one account and credit another account. It is this recording of two fold effect of every transaction that has given rise to the term Double Entry”.- J.R Batliboi
