The audit date is close, but the records are not in one place. Bank statements sit in the accounting system, payroll reports are in a provider portal, vendor bills are in email, and unusual transactions are buried in messages with the owner or operations team. That scramble is common for small and midsize businesses, but it makes simple questions take too long to answer.
An audit ready checklist should do more than list documents. It should show a clear trail from each reported number to its source document, approval, reconciliation, and final treatment. It should also tell finance, payroll, HR, and operations who owns each task, what happens before the audit, how requests are handled during fieldwork, and what gets improved afterward.
The eight checks below focus on the records auditors test most often. They also include a short document-gathering plan, practical examples from construction, healthcare, professional services, and other SMB settings, and ways to reduce the burden on an already busy team. If your staff is stretched thin, a bookkeeping or CFO partner such as MyOfficeOps can help organize the work. Businesses in regulated fields can also compare the process with guidance on preparing for an AHPRA audit.
1. Organize and Reconcile All Bank and Credit Card Accounts
The first reconciliation often surfaces duplicated entries. A fuel charge may have entered the books once from a receipt and again through a bank feed. Other reviews uncover personal charges in business accounts, or a bookkeeping error that has distorted profitability reporting for months. Correcting these items is easier while the transactions and business context are still familiar.
Every bank account and credit card should appear in the books, with recorded activity agreeing to the statements for the period under review. Work through each account month by month. Document timing differences, including checks that have not cleared and deposits still in transit. A bank account reconciliation guide can help standardize the working file and review steps.
What to check before the auditor asks
Use the accounting software's reconciliation tools, but treat a green status as a starting point, not proof. Retain the reconciliation report, bank statement, outstanding-item list, and supporting notes together.
- Cover every account: Include operating accounts, savings, credit cards, merchant accounts, and accounts used for a project or separate entity.
- Track open items: Maintain a current list of pending checks, deposits in transit, disputed charges, and transactions awaiting classification.
- Explain unusual activity: Record the reason for a large payment, owner charge, transfer, or customer refund.
- Work in a sensible order: If the books are behind, begin with the most recent month and work backward. Mark unfinished periods and explain what remains.
Practical rule: A reconciliation provides evidence only when another person can understand the difference and why it remains open.
Finance should own the reconciliations. Operations can confirm project-related purchases, while owners or department leaders approve personal-use corrections and unusual transfers. Before the audit, assign these confirmations and approvals clearly. During fieldwork, provide one complete file instead of separate statements, screenshots, and explanations. Afterward, set a monthly close deadline so the process becomes routine rather than an annual emergency.
2. Review and Document All Journal Entries
Owner distributions posted to an expense account, a year-end revenue adjustment without a contract attached, provider expense allocations calculated but never explained. These are the journal entries auditors question first because they can change reported results without passing through routine billing or payment controls.
Journal entries include corrections, accruals, reclassifications, closing entries, and other adjustments. For each one, an auditor will want to know who prepared it, why it was needed, what evidence supports it, and who reviewed it. Resolving weak documentation before fieldwork gives the business time to correct the entry and explain the decision.
Build a journal entry trail
Keep a journal entry log throughout the year. Each entry needs a unique reference, date, preparer, reviewer, business reason, accounts affected, and links to supporting documents. Make the records easy to match. Entry J-104 should point to a file with the same reference, not a general folder containing unrelated attachments.
- Require support every time: Attach contracts, invoices, schedules, calculations, or approval emails.
- Separate preparation and review: The person who creates an entry should not be the only person deciding that it is correct.
- Flag higher-risk entries: Apply a company-approved threshold or risk rule for extra review instead of relying on memory at year-end.
- Explain the business purpose: “Move expense to correct department” is stronger when it identifies the invoice, department, and reason for the original error.
A useful journal entries reference can help newer staff distinguish entries from corrections that belong in the normal transaction process.
Finance should own the log. Department managers can confirm allocations and business reasons, while HR or operations may need to validate entries tied to staffing, projects, or service delivery. Assign those responsibilities before the audit, then provide the auditor with each entry, its support, and approval as one package during fieldwork.
After the audit, record every proposed adjustment and decide whether the underlying process needs to change. A recurring correction usually signals a workflow problem, not only a one-time mistake.
3. Prepare and Verify Accounts Receivable Aging
An accounts receivable aging report reveals what customers owe and how long each balance has been open, information auditors use to test whether reported revenue will convert to cash. An old invoice may be valid, disputed, covered by a payment plan, duplicated, or unlikely to be collected. Finance should identify the situation behind each material balance before the audit begins.
Review the report for customers with overdue balances, duplicate invoices, unresolved credits, or patient accounts that remain difficult to collect despite correct billing. Leaving every old balance unchanged can overstate expected cash receipts and invite questions about the financial statements.
Review each open balance
Send detailed customer statements where appropriate and compare responses with the accounts receivable ledger. For older items, retain evidence of calls, emails, letters, disputes, and payment arrangements. If a balance is unlikely to be collected, discuss the appropriate accounting treatment with the responsible finance professional and document the decision.
- Confirm the invoice exists: Match the invoice to the contract, engagement letter, service record, or delivery evidence.
- Check for duplicates and credits: A credit memo, duplicate billing, or unapplied payment may mean the customer owes less than the report shows.
- Document collection activity: Keep notes showing what the business did to resolve older balances.
- Review expected losses: If specific amounts appear uncollectible, record the appropriate reserve or write-off under the business's accounting policy.
The accounts receivable aging report template gives finance a consistent starting point for grouping balances and recording follow-up.
Finance owns the aging report. Sales and account managers can explain customer disputes or service issues, while clinic administrators can verify patient account details. Before fieldwork, assign these tasks and tie the aging report to the general ledger. During the audit, provide support for significant balances, including invoices, correspondence, payment records, and documented decisions.
After the audit, record proposed adjustments and assign follow-up owners. Make receivables review part of the monthly close so collection issues are addressed before the next audit cycle.
4. Complete Accounts Payable Reconciliation and Cutoff Testing
Accounts payable testing focuses on whether the business recorded every obligation in the correct accounting period. A construction company receives a $45,000 subcontractor invoice in January for work completed in December. Under accrual accounting, that expense belongs in the earlier period, and the auditor will check whether it was recorded there.
Cutoff errors can also arise from duplicate payments, missing credits, disputed invoices, or bills sitting in an approval queue. These issues affect both the expense balance and the amount owed to vendors, so the supporting records need to show what was received, approved, recorded, and paid.
Check the bills around the reporting date
Compare the accounts payable aging with unpaid invoices, subsequent payments, purchase orders, receiving records, and vendor statements. Prepare a year-end schedule listing the invoice date, service date, receipt date, payment status, and accounting period. Finance can then explain the treatment of each item instead of reconstructing decisions during fieldwork.
- Record bills promptly: Route invoices from shared inboxes and personal email accounts into a controlled workflow.
- Test the boundary: Review invoices received just before and just after the reporting date, especially for services already delivered.
- Confirm large balances: Ask significant vendors to verify unpaid amounts when the balance could affect the financial statements.
- Trace later payments: A payment after year-end may identify an obligation that existed before year-end.
- Check credits and duplicates: Match credit memos, payment records, and vendor statements to the ledger so liabilities are not overstated.
Operations and purchasing should confirm when goods or services were received. Finance owns the reconciliation and cutoff file, while department managers resolve disputed invoices and approve corrections. Before the audit, assign these tasks and assemble invoices, approvals, receiving evidence, and payment details. During fieldwork, provide that support with the related ledger entries. After the audit, record adjustments and give each workflow issue an owner. A monthly cutoff review reduces the amount left to resolve at year-end.
5. Reconcile Payroll Records and Tax Filings
Payroll errors are hard to explain because several records should agree at once. The payroll register should connect to the accounting ledger, cash payments, tax filings, employee reporting, and liability accounts. Finance shouldn't assume the payroll provider's report automatically matches the books.
A professional services firm might fail to accrue the final pay period. A construction company could find that gross wages in the ledger don't match amounts reported on employee forms. A healthcare practice may have employer health insurance contributions recorded incorrectly. These differences often come from timing, corrections, benefit treatment, or manual entries, so the explanation needs to be written down.
Keep the payroll file complete
Compare payroll registers with the general ledger and payroll tax filings. Review federal filings such as Form 941, year-end Form W-2 and W-3 records, state filings, payment confirmations, and any correction paperwork. Keep the reconciliation for each period, not just a final year-end summary.
- Review accruals at close: Check unpaid wages, payroll taxes, benefits, bonuses, and other liabilities at month-end and year-end.
- Organize by filing type: Keep federal, state, local, and employee reporting records in a logical folder structure.
- Explain corrections: Attach the payroll provider report, approval, and accounting entry for each adjustment.
- Include HR support: HR should confirm hiring, termination, compensation, benefits, and leave changes that affect payroll.
The IRS says businesses should keep employment tax records for at least four years after filing the fourth-quarter return for the year, and certain records connected with qualified sick leave wages, qualified family leave wages, and certain employee retention credit wages should be kept for at least six years. See the IRS employment tax recordkeeping guidance for the specific categories.
Payroll should own the source reports, finance should reconcile the accounting, and HR should explain employee changes. During the audit, use one controlled document set. Afterward, review every difference and update the payroll-to-ledger process if the same issue could happen again.
6. Identify and Document All Significant or Unusual Transactions
Routine transactions usually have routine support. Unusual transactions need more context because an auditor can't understand their purpose from the general ledger description alone. Create a running list of one-time sales, equipment purchases, loans, owner withdrawals, settlements, unusual discounts, related-party activity, and other items outside normal operations.
A law firm may need to explain a large client settlement. A construction contractor might need to show why a major equipment purchase was necessary for the business. A healthcare practice could be asked to support a significant provider bonus or distribution. The transaction may be valid, but the file should make that clear without forcing someone to search through old email.
Capture the reason, not just the amount
Set a review threshold that fits the size and risk of the business. Don't use a threshold as an excuse to ignore smaller unusual items. A small transaction can still matter if it involves an owner, related party, unusual terms, or a new type of activity.
- Describe the event: State what happened, when it happened, and why the business entered into it.
- Attach the agreement: Include contracts, invoices, settlement documents, loan papers, purchase records, or customer communications.
- Show approval: Save owner, manager, or board approval where applicable.
- Connect the accounting: Identify the ledger account, journal entry, payment, and financial statement line affected.
- Record exceptions: If support arrived late or a process was bypassed, explain the reason and the corrective action.
Operations and department leaders often know the business reason better than finance. Finance should maintain the transaction register, while owners or authorized managers confirm approval. During fieldwork, provide a short summary with the evidence. Afterward, add recurring transaction types to the standard approval workflow so they stop being “unusual” from a control perspective.
7. Audit and Correct Asset and Liability Account Balances
Assets and liabilities need more than a ledger balance. The business should be able to show that each significant asset exists, belongs to the business, and is recorded under the right accounting policy. It should also be able to prove that loans, leases, credit lines, and other obligations match the current agreements and statements.
A construction company might still carry equipment that was sold years ago. A professional services firm could have a lease obligation missing from its records. A healthcare practice may have an incorrect depreciation calculation for medical equipment. These errors can distort both the balance sheet and the costs reported in the income statement.
Build evidence around the balance sheet
Maintain a fixed asset register with purchase date, cost, location, description, serial number where relevant, depreciation details, and disposal status. Keep loan statements, credit agreements, lease documents, and repayment schedules by account. For valuable equipment, photographs and serial numbers can help operations confirm that the item is still on site.
A practical review should include:
- Existence: Walk through the facility or job sites and confirm that significant assets are present.
- Ownership: Match purchases to invoices, contracts, titles, or other ownership records.
- Valuation: Check depreciation, impairment indicators, disposals, and repairs that may have been classified incorrectly.
- Completeness: Compare loan and lease statements with the liability accounts and search for obligations outside the accounting system.
- Classification: Confirm that current and long-term portions, equipment and repairs, and other categories follow the business's accounting policy.
Finance should prepare the schedules. Operations can verify assets, and owners or managers should approve disposals and new financing. During the audit, provide the register and supporting documents as a connected package. Afterward, schedule a regular asset and liability review instead of waiting for the next year-end close.
8. Prepare a Trial Balance and Review for Unusual or Unexpected Balances
The trial balance is the final wide-angle view of the books before financial statements are prepared. It lists the balances in the accounts and helps finance spot errors that individual reconciliations may miss. Read it line by line and ask whether each balance makes sense for the business.
A consulting firm might see retained earnings fall sharply without a clear reason. A construction contractor could find a negative accounts payable balance. A healthcare practice might have an expense account with a credit balance when it should normally carry a debit. These are not automatically errors, but they deserve an explanation and supporting work.
Use the trial balance as a question list
Compare the current trial balance with the prior period and investigate changes that don't match revenue, staffing, projects, financing, or other business activity. Review accounts that should be cleared, including temporary accounts and suspense or clearing accounts. Confirm that the chart of accounts separates transaction types clearly enough for the financial statements to tell a useful story.
- Check account direction: Look for assets, expenses, liabilities, equity, and revenue accounts carrying an unexpected sign.
- Review dormant accounts: Investigate accounts that should be zero but still contain activity.
- Trace unusual movement: Link large changes to reconciliations, journal entries, contracts, or operational events.
- Ask for an independent review: Someone who didn't prepare the books may notice a pattern the preparer has learned to overlook.
Finance owns the trial balance review, but department managers can explain changes in payroll, project costs, sales, or equipment. During the audit, keep the reviewed trial balance, adjustment log, and supporting schedules together. After the audit, turn recurring questions into monthly close checks.
The structure of those checks should reflect the audit's scope. Financial statement audits, IRS examinations, lender field exams, SOC or ISO reviews, and payroll or tax audits don't request the same evidence. Start by confirming the engagement, building a request log, assigning owners, and identifying which records must be retained. PCAOB standards require auditors to retain audit documentation for seven years in the stated public-company audit circumstances, and the final documentation set must be assembled within 45 days after the report release date. Federal award audits generally require retention for a minimum of three years after the audit report is issued, with agencies able to extend the period in writing. The PCAOB audit documentation standard explains those requirements.

Turn Audit Prep Into a Year-Round Habit
Audit preparation works best as a normal operating rhythm. Reconcile bank and credit card accounts monthly. Save support when a journal entry is created, not months later. Review receivables, payables, payroll, tax filings, assets, liabilities, and the trial balance during the close process. A shared, secure folder should serve finance, payroll, HR, and operations, with clear naming, controlled versions, and owners for each file.
Records also need to remain available after the audit. IRS Publication 583 says businesses should keep records as long as they may be needed to administer tax law, generally until the period of limitations for the return expires. It also states that employment tax records should be kept for at least four years after the tax is due or paid, whichever is later. The IRS recordkeeping publication provides that guidance. Separate business-record guidance also identifies ownership records such as formation documents, bylaws, stock ledgers, and property deeds as records that may need permanent retention, while payroll tax records commonly require at least four years of retention. See this business records retention guidance when designing the company's policy.
During the audit, name one main contact. That person should route requests to the right owner, answer from the controlled document set, and maintain a request log with the question, assigned person, response, open issue, and due date. Finance can handle reconciliations and schedules, payroll can provide filing records, HR can support employee changes, and operations can confirm purchases, assets, customer activity, and service dates. This division keeps the auditor from receiving conflicting versions of the same information.
After the audit, don't file the report and forget the process. Record each adjustment, control issue, unanswered question, and improvement opportunity. Assign an owner and a due date. If a missing approval caused a delay, fix the approval path. If a recurring reconciliation takes too long, change the workflow or system. Internal control quality matters because the COSO framework groups effective control into five components, including the control environment, risk assessment, control activities, information and communication, and monitoring activities. The COSO framework overview explains how those pieces work together.
Access deserves specific attention when the business uses cloud accounting, outsourced finance, multiple entities, or remote staff. Maintain an inventory covering human users, service accounts, and AI identities. Remove standing or broad privileged access where possible, use just-in-time access that expires, document approvals, and keep centralized logs tying privileged actions to specific requests. Readiness material reports that 34% of companies fail their first readiness assessment because of access-control gaps, including shared credentials, excessive permissions, or missing MFA, as described in this 2026 access-control benchmark. This is a control task for IT and operations, but finance should care because the accounting system's access history can become audit evidence.
