What is Double-Entry System?
Double-entry refers to a system of bookkeeping that, while quite simple to understand, is one of the most important foundational concepts in accounting. Basically, double-entry bookkeeping means that for every entry into an account, there needs to be a corresponding and opposite entry into a different account. It will result in a debit entry in one or more accounts and a corresponding credit entry in one or more accounts.
CONCEPT OF DOUBLE ENTRY SYSTEM:
Among the oldest known and indisputable principles of accounting is the Double Entry principle.
The principle states that, ‘for every debit entry there must be a corresponding credit entry’, which in everyday English means that for every receiver there must be a giver.
The receiver is always regarded as the Debtor whiles the giver as a creditor under this principle.
As far as double entry principle is concerned, there must always be two parties to a transaction.. One entry at the debit side for the debtor or the receiver and the other entry at the credit side for the creditor or the giver.
Brief History of Double-Entry Bookkeeping
Double-entry bookkeeping has been in use for at least hundreds, if not thousands, of years. Accounting has played a fundamental role in business, and thus in society, for centuries due to the necessity of recording transactions between parties.
The early beginnings and development of accounting can be traced back to the ancient civilizations in Mesopotamia and is closely related to the development of writing, counting, and money . The concept of double-entry bookkeeping can date back to the Romans and early Medieval Middle Eastern civilizations, where simplified versions of the method can be found.

Preventing Errors Through Double-Entry Bookkeeping
