The concepts of accounting include:
1. **Accrual Concept**: Revenues and expenses are recorded when they are earned or incurred, not when cash is received or paid.
2. **Consistency Concept**: Accounting methods should be applied consistently from one period to another.
3. **Going Concern Concept**: Assumes that a business will continue to operate indefinitely.
4. **Matching Concept**: Expenses should be matched with the revenues they help to generate in the same period.
5. **Economic Entity Concept**: Business transactions are separate from the personal transactions of its owners.
6. **Monetary Unit Concept**: Only transactions that can be measured in monetary terms are recorded.
7. **Time Period Concept**: Financial statements are prepared for specific periods of time, such as months or years.
