The Accounting Cycle

From Receipt to Report

The accounting cycle is the fixed sequence that turns raw business events into usable financial statements. Every firm, every period, every time:

1. Identify transactions from source documents — invoices, receipts, bank statements. If no document exists, neither does the transaction (the paper trail is not a formality; it is the evidence base).
2. Journalize — record each transaction as a journal entry (date, accounts, debit, credit, narration). The journal is the chronological record.
3. Post to the ledger — transfer each entry to the relevant T-accounts in the general ledger. The ledger is the by-account record: same data, different index.
4. Prepare a trial balance — list every ledger account and its balance. Total debits must equal total credits. If they don't, hunt the posting error.
5. Adjust — accruals and deferrals that align revenues and expenses with the period they belong to (next unit lesson: adjusting entries).
6. Prepare financial statements — the income statement, balance sheet, and cash flow statement are built from the adjusted trial balance.
7. Close — zero out temporary accounts (revenues, expenses) by transferring their balances into retained earnings. This resets the income measurement for the next period.
8. Post-closing trial balance — verify that only permanent accounts (assets, liabilities, equity) remain and that they still balance.

The accounting cycle: journal → post → ledger → list → trial balance → adjust → statements → close → next period.

The cycle's genius is separation of concerns: the journal captures when, the ledger sorts what, the trial balance checks arithmetic, adjustments enforce matching, and closing resets the clock. Each step makes the next step's job possible — and each step's output is auditable independently.

Same data, two indexes

Common pitfall: Treating a balanced trial balance as proof the books are right. It only proves debits equal credits — a transaction posted to the wrong account, recorded twice, or omitted entirely balances perfectly and is still wrong.
