Money Measurement Concept
The money measurement concept defines that only monetary transactions that can be expressed in monetary value are recorded in accounting. Non-monetary transactions are not recorded in the accounting system.
Business Entity Concept
It is also known as the Economic Entity Assumption; the concept holds that the business and the owner are separate entities and must be treated separately. Even for sole proprietorship firms, financial activities must be kept strictly independent from the owner’s personal finances.
Single Entity concept
If there are no debit and credit rules in accounting activities and only personal accounting, including cash and cash content of real accounts are recorded, then this type of accounting approach is known as the single entity concept. This concept is only used in the household sector, but not in the business and organizational sector.
Cost Basis/Cash Basis Concept
Accounting keeps a record only of cash-based transactions of a given period of time. This concept excludes receivable and payable transactions.
Accrual Basis Concept
The accrual basis concept tells that the business transaction includes cash, receivables, and payable transactions. All the transactions that happen over a given period of time should be included in the accounting. It records the revenue when earned and records the expenses when incurred, regardless of when cash is exchanged.
Double Entry Concept
If every financial activity is recorded by using the rule of debit and credit, then such a modern, fundamental, systematic, and scientific concept of accounting is called the double-entry system.
Going Concern Concept
While performing accounting activities, it should be considered that the organization will run forever. This concept defines the rule of accounting preparation with the mindset that the organization never terminates. i.e., organization runs on a perpetual succession basis, meaning the organization continues to exist and operate independently of its members, directors, or owners.
Matching Concept
There must be coordination between the income and expenses of the entity. Those expenses that are related to income-generating activities within a given period of time should be recorded. (Concept of if you invest, you should get a return).
Historical Cost Concept
The historical cost concept tells that organizations record financial transactions considering the original price, not the market price. The valuation of the fixed assets should be recorded in their original price, not in their current value.
Accounting Period Concept
Every 12 months should be considered as an accounting period or fiscal year for the recordkeeping and reporting of financial transactions. The accounting period concept is also called the periodicity concept.
