Accounting Concepts and Conventions
• Entity Concept
o The accounting system must distinguish between the business and its owner/s
o An entity is considered separate from its owners and from any other business
o This concept separates the activities of the business from its owner/s
• Transactions
o The accounting process usually begins with a business transaction
o A transaction is an exchange of property or service with another entity
o Each transaction is recorded in the accounting system based on information from source
document
• Source documents
o These are business records used as evidence that a transaction has occurred
o Common ones include rales receipt, invoices, delivery advices and payroll timesheets
o Some transactions can include multiple source documents
• Monetary unit concept
o Transactions and the source documents on which they are based show the value of the
exchange in terms of money
o Transactions recorded using a consistent monetary unit (national currency)
• Historical cost concept
o The value of each country's currency changes over time
o The value of particular goods and services also change with changes in economic forces
like inflation
o Businesses generally do not record changes in either the value of currency or goods and
services
o A business records its transactions based on dollars exchanged at the time the
transaction occurred
• Accounting equation
o Assets = Liabilities + Owner's Equity
o Balance sheet is a formal representation of this
o Used to analyse business transactions
o An accountant or owner identifies transactions and records them in the business'
accounting system
• Assets
o A business' economic resources that will provide future benefits to the business
o Includes cash, accounts receivable and inventories
o Other types have physical substance e.g. land, buildings and equipment
o Some are instead legal rights like copyrights and brand names
• Liabilities
o Economic obligations (debts) of the business
o Includes accounts payable, wages payable and amounts owed to a financial institution
• Owner's equity
o Is a residual claim on the business representing the owner's current investment in the
net assets (assets - liabilities) of the business
o The capital invested by the owner/s, the profits earned by the business and the
withdrawals of capital all affect owner's equity
o It's a residual because the creditors have the first legal claim to the business assets
