What are the Accounting principles and concepts?

Accounting basics are the building blocks of accounting theory such as:
- what asset, liabilities, equity, revenue and expenses are;
- double sided accounting; and
- time value of money.

Accounting concepts generally refers to the four pillars of accounting theory:
- Going Concern: the assumption that the company you are accounting for is going to continue to operate in the future (and not be wound-down or go bankrupt unless there is compelling evidence to the contrary).
- Consistency: the accountant will use the methods of valuing and recording transactions year-over-year unless they disclose otherwise.
- Conservatism: the accountant will be cautious about what and when they record items on the books.
- Matching: revenues and expenses which are related should be recorded over the same accounting period.
