Understanding Adjusting Entries and Why They Matter
Learn how adjusting entries capture revenues and expenses in the correct period, and why they’re essential for accurate financial reporting.

Here’s the thing: your books need to match reality. Not when you actually get paid—when you actually earned the money. Same with expenses. You’ve probably heard about “accruals” and “deferrals.” They’re not complex, but they’re critical. Get them wrong, and your financial statements are misleading. Get them right, and you’re audit-ready.
Auditors spend significant time on these entries because they directly affect your net income. That’s why we’re walking through each type with concrete examples you’ll recognize.
Think of these as timing adjustments. You’ve earned revenue or incurred an expense—now you need to record it in the right period. Here’s each one:
You’ve delivered work or goods, but haven’t received payment yet. This is income you’ve earned but not collected. Example: You completed a consulting project in December, but the client pays you in January.
Journal entry: Debit Accounts Receivable, Credit Revenue
You’ve incurred an expense but haven’t paid for it. You owe money for something you’ve already used. Example: Utilities consumed in December but billed in January.
Journal entry: Debit Expense, Credit Accounts Payable
You’ve received payment for work you haven’t done yet. It’s income received in advance. You’ll recognize it as revenue when you deliver the goods or services. Example: Annual software subscription paid upfront in January for 12 months of access.
Journal entry: Debit Cash, Credit Unearned Revenue
You’ve paid for something you haven’t used yet. It’s an expense you’ve prepaid. You’ll record it as an expense over the period you use it. Example: Office insurance paid in advance for 12 months.
Journal entry: Debit Prepaid Expense, Credit Cash
Let’s walk through a concrete scenario. You’re a consulting firm. In December, you bill a client $8,000 for work completed. You expect payment in January. Here’s what happens:
Work is completed (Dec 31): You’ve earned the revenue. Record it now—don’t wait for payment.
The adjusting entry (Dec 31): Debit Accounts Receivable $8,000 / Credit Service Revenue $8,000. This shows the income in the correct period.
Payment arrives (Jan 15): Debit Cash $8,000 / Credit Accounts Receivable $8,000. You’re just collecting what you already recorded.
Without that adjusting entry in step 2, your December revenue would be understated and your January revenue overstated. Your financial statements wouldn’t reflect what actually happened.
December 31st is a cutoff date. Everything that belongs to 2026 goes in 2026’s statements. Everything that belongs to 2027 goes in 2027’s statements. No overlap, no ambiguity.
That’s where accruals and deferrals come in. They help you separate what belongs to each year. You might have:
Get the timing wrong on even a few items, and your net income can swing significantly. Auditors know this. They’ll ask detailed questions about how you identified and recorded these adjustments.
Auditors don’t just check if you recorded accruals—they verify they’re correct and complete. Here’s what they’ll examine:
Did you capture all accruals and deferrals? They’ll test for items you might’ve missed—unpaid invoices, pending bills, contracts with unusual terms.
Are the amounts correct? They’ll recalculate accruals and trace them to supporting documents—contracts, invoices, delivery confirmations.
Can you back it up? Have you documented your reasoning? Keep a log of adjusting entries with dates, amounts, and the business reason for each one.
Does it belong in this period? They’ll verify the economic event actually occurred in the year being audited, not before or after.
You don’t want to scramble when your auditor arrives. Start early. Begin in November—not January. Here’s a practical approach:
Review contracts: Identify anything with payment terms that might span year-end. Service contracts, retainers, annual memberships.
Confirm outstanding invoices: Which client invoices are unpaid as of December 31? These are accrued revenue.
Check for unbilled expenses: Utilities, rent, wages—anything you’ve used but not yet been billed for?
Verify prepaid items: Insurance, subscriptions, licenses paid in advance. Calculate how much belongs to next year.
Identify deferred income: Payments received for work you haven’t completed yet. Track how much revenue you’ll recognize in each future period.
Document everything: Create an adjusting entries schedule. Show the debit and credit, the amount, and the business reason. This is what auditors want to see.
Accruals and deferrals aren’t optional—they’re fundamental to accurate financial reporting. You’ve earned revenue, so record it. You’ve incurred an expense, so book it. Don’t wait for payment or the bill to arrive.
The effort you put in now, before your audit, pays dividends. You’ll have supporting documentation ready. Your auditor won’t need to hunt for information or question your judgment. Your statements will be accurate and audit-ready. That’s the goal.
Don’t wait until December 31st to think about accruals. Start your year-end closing checklist now. Review contracts, confirm invoices, and prepare your adjusting entries schedule. You’ll be ahead when your auditor arrives.
