What Auditors Actually Look For — And How to Prepare
Demystify the audit process. Learn what auditors examine during fieldwork, what questions they’ll ask, and how to answer confidently. Real auditors explain their priorities.
Most companies worry about the wrong things during audits. We’ll show you exactly what matters to auditors and how to prepare properly.
Why Auditors Ask the Questions They Do
Auditors aren’t trying to catch you out. They’re looking for evidence that your financial statements are accurate and your systems work properly. That’s it. But they’re thorough because that’s their job — they need to be confident enough to sign off on your numbers.
Understanding what they’re actually checking for helps you prepare better. You’ll know what documents to organize, what processes to have in place, and what explanations they’ll want to hear.
Transaction Documentation
Supporting invoices, receipts, and evidence for every significant transaction recorded in your books.
Internal Controls
Processes that prevent errors or fraud — approvals, segregation of duties, reconciliations, and reviews.
Accounting Policies
Clear, documented policies for revenue recognition, expense classification, depreciation, and other estimates.
What Happens During Fieldwork
1
Planning & Risk Assessment
Auditors review your business, industry, and previous audit results. They’re identifying where errors are most likely — that’s where they’ll focus.
2
Testing Transactions & Balances
They’ll select sample transactions from your books and ask for supporting documents. They’re checking that recorded amounts match actual evidence — invoices, bank statements, contracts.
3
Evaluating Internal Controls
They’ll walk through your approval processes, ask who checks what, and observe how you handle transactions. Are controls actually working, or just documented?
4
Verification & Confirmation
For major balances like receivables or payables, auditors may contact your customers or suppliers directly to verify amounts. This isn’t about trust — it’s standard procedure.
Questions You’ll Definitely Get Asked
Revenue Recognition
“Walk us through how you recognize revenue. When do you record a sale?” They’re checking that you’re following accounting standards and not accelerating revenue recognition. Have a clear policy documented — percentage of completion, point of delivery, whatever your method is.
Cut-off & Period-End Transactions
“Show me how you handle transactions near year-end. How do you make sure December sales aren’t recorded in January?” This catches intentional misstatement. You need documented procedures for cut-off.
Estimates & Judgments
“How do you calculate your depreciation rates? Bad debts? Provisions?” Estimates involve judgment. Auditors want to see that you’ve thought this through and can defend your numbers. Write down your assumptions.
Related Party Transactions
“Do you have any transactions with related parties — directors, family members, other companies you control?” You need to disclose these and show they’re at arm’s length. Even innocent transactions need documentation.
Your Practical Preparation Checklist
Organize Documents
Gather all supporting documents for significant transactions — invoices, contracts, bank statements, receipts. Create an index so auditors can find things quickly.
Document Policies
Write down your accounting policies — how you recognize revenue, depreciate assets, handle provisions. One or two pages per policy is fine.
Review Reconciliations
Make sure bank reconciliations are current. Reconcile balance sheet accounts to supporting details. Document any unusual items.
Verify Controls
Walk through your approval processes. Make sure the people who should be approving transactions actually are. Document who has what access.
Review Prior Issues
If last year’s audit raised any points, make sure you’ve addressed them. Auditors will ask what you’ve done to fix previous findings.
Brief Your Team
Make sure finance staff know auditors are coming. They should understand what questions might come up and know who to refer them to.
“The companies that prepare best aren’t the ones with perfect numbers — they’re the ones that know their numbers and can explain them. Auditors respect that.”

The Bottom Line
Auditors aren’t your adversaries. They’re looking for evidence that your financial statements are accurate and your systems work. When you understand what they’re checking for, you can prepare confidently.
Focus on three things: organized documentation, clear policies, and functioning controls. Get those right and you’ll breeze through fieldwork. You’ll know what auditors are looking for — and they’ll see you’re ready.
