You can talk about the history of double entry system for hours, that how the system has evolved over the years but letâ€™s keep it simple and understand how double entry system works.

What is Double Entry Accounting System?

Not able to understand ? See this, if you are buying a mobile by paying 20,000 Rs in cash.

If you closely look at the above example, the transaction as two parts in it: You are receiving a mobile which can be called as receiving aspect. The second one, you are paying cash which can be termed as giving aspect.

receiving and giving aspect

Now when you apply the double entry system of bookkeeping, it recognizes and records both the aspect; receiving and giving aspect in the books of accounts.

Considering the above definition, every transaction will have at least two accounts which are impacted. In the above example, computer is one account and cash is the other account.

So, when books are maintained using double entry accounting system, every transaction involves a debit entry in one account and credit entry in another account. This because, you have an account which receives the value and another account which has given the value.

When you look at the above example, computer account will be debited since it has received the value (inward) and cash account will be credited because it has given the value (outward).

To summarize, under double entry accounting system, in every transaction an account is debited, and some other account is credited.

Before you record, find out two accounts affected by a particular transaction and next, out of these two accounts which account is required to be debited and credited.
