The accounting cycle begins by capturing every financial event a business experiences. Each time the company buys inventory, pays an employee, or makes a sale, that transaction is analyzed and recorded as a journal entry. This entry always follows the rules of double-entry bookkeeping, debiting one account and crediting another to keep the fundamental accounting equation, $Assets = Liabilities + Equity$, in balance.

These individual journal entries are then posted to the general ledger, which is the complete record of all financial transactions. Think of the ledger as a collection of all the individual accounts, like Cash, Accounts Receivable, and Sales Revenue. At the end of an accounting period, we need to check if our bookkeeping is mathematically correct. We do this by preparing an unadjusted trial balance.

If the totals match, it's a good sign, but it doesn't mean the financial records are perfect. It only confirms the math of our debits and credits is balanced. It won't catch an entry that was never recorded or one posted to the wrong account. More importantly, it doesn’t account for economic events that have occurred but haven't been recorded yet through a daily transaction. That's where adjusting entries come in.

Financial statements should reflect a company's performance and position accurately for a specific period. This is achieved through accrual basis accounting, which requires us to follow the matching principle. The matching principle dictates that expenses must be matched with the revenues they helped generate, regardless of when cash changes hands.

Adjusting entries are journal entries made at the end of an accounting period to align revenues and expenses to the proper period. They ensure the financial statements are a true reflection of the company's activities. These entries always involve one income statement account (a revenue or expense) and one balance sheet account (an asset or liability).

Adjusting entries fall into two main categories: deferrals and accruals.

Let's break down the types within these categories:

• Prepaid Expenses (a deferral): A company pays for an expense in advance, creating an asset (like Prepaid Insurance or Supplies). An adjusting entry is needed to recognize the portion of the asset that has been used up during the period. For example, if a company pays $1,200 for a year of insurance, at the end of each month, it would record $100 of Insurance Expense and reduce the Prepaid Insurance asset by $100.

• Unearned Revenue (a deferral): A company receives cash from a customer before providing the service or product. This creates a liability (Unearned Revenue). The adjusting entry recognizes the portion of the revenue that has been earned during the period. If a magazine publisher receives $120 for a yearly subscription, it would recognize $10 of Subscription Revenue each month and reduce the Unearned Revenue liability.

• Accrued Expenses (an accrual): An expense has been incurred, but the company hasn't paid for it yet. A common example is employee salaries. If the accounting period ends on a Wednesday, but payday is Friday, the company must record the salary expense for Monday, Tuesday, and Wednesday and create a corresponding liability (Salaries Payable).

• Accrued Revenue (an accrual): A company has earned revenue by providing a service, but it hasn't billed the customer or received payment yet. The adjusting entry records the revenue and creates an asset (Accounts Receivable) to reflect the amount owed by the customer.

After all adjusting entries are journalized and posted to the general ledger, an adjusted trial balance is prepared. This new trial balance includes the updated balances of all accounts. It serves as the final, accurate source of data for creating the financial statements: the Income Statement, the Statement of Retained Earnings, and the Balance Sheet.

The adjusted trial balance confirms that debits still equal credits after all adjustments and provides the organized, correct figures needed for reporting.

The final steps of the cycle involve closing the books for the period. This means resetting the balances of all temporary accounts to zero to prepare them for the next period.

• Temporary Accounts include all revenue, expense, and dividend accounts. They relate to only one accounting period.
• Permanent Accounts are all balance sheet accounts, including assets, liabilities, and equity. Their balances carry forward from one period to the next.

The closing process involves making journal entries to transfer the balances of all temporary accounts into the Retained Earnings account. First, revenue and expense accounts are closed to a summary account called Income Summary. Then, the balance of Income Summary (which equals the net income or loss) and the Dividends account are closed to Retained Earnings.

After the closing entries are posted, a post-closing trial balance is prepared. This final trial balance lists only the permanent (balance sheet) accounts, as all temporary accounts now have a zero balance. Its purpose is to verify that debits still equal credits and that the books are ready for the start of the next accounting period. The cycle is now complete and ready to begin again.

This systematic process ensures that financial information is recorded consistently and accurately, providing a reliable foundation for business decisions.
