The accounting cycle involves recording business transactions, preparing financial statements, and closing books at the end of each accounting period. It is based on key assumptions and principles including:
1) Transactions are recorded based on the accrual concept, which matches revenues to expenses in the period they are incurred regardless of when cash is received or paid.
2) Financial statements are prepared at the end of each period using the adjusted trial balance to provide an accurate picture of the company's financial position and performance.
3) The accounting equation (Assets = Liabilities + Equity) must always balance through double-entry bookkeeping, where every transaction has equal and offsetting debits and credits.
