Introduction to Bookkeeping

What is Bookkeeping?

Bookkeeping is the process of recording all business financial transactions in a systematic manner.

It answers:

  • What money came in?
  • What money went out?
  • Who owes the business?
  • Who the business owes?

It is important to note that bookkeeping is not accounting. Bookkeeping is merely recording transactions while accounting refers to interpreting transactions and then proceeding to record them.

The Accounting Equation

Everything in bookkeeping is based on the accounting equation, the formula is as follows:

Assets = Owner's Equity + Liabilities
Element Meaning
Assets What the business owns
Liabilities What the business owes
Equity Owner's claim to the business

Double Entry Principle

Every transaction affects at least two accounts.

For every DEBIT there must be a CREDIT.

'Debit' refers to money coming into the business while 'Credit' refers to money owed by the business.

Trial Balance

A Trial Balance lists all ledger balances. Your total debits should equal your total credits — if they match, the arithmetic is likely correct.
