Year-End Financial Audits Made Simple: What to Do Before Auditors Arrive

Hearing the word audit is enough to make even the most organized business owner feel a little uneasy. It’s not just about compliance — it’s about proving that your numbers tell an accurate story of your business.

But here’s the truth: a year-end financial audit doesn’t have to be stressful. With the right preparation, it can actually be one of the most valuable moments in your financial year. It’s your chance to validate your data, strengthen your controls, and build confidence in your numbers.

So before the auditors walk in (or log in), here’s what you can do to make the process smooth, efficient, and maybe even a little satisfying.

Get Your Books in Order

An audit starts with your books — so make sure they’re clean, current, and complete. Review all your financial accounts and confirm that every transaction is recorded correctly.

Reconcile bank accounts, credit cards, loans, and payroll to ensure your balances match. Verify that all adjusting entries (like depreciation, accruals, or prepaid expenses) are updated. The goal is to hand over a complete, accurate financial picture — not a stack of unresolved questions.

If your accounting system has been updated throughout the year (with the help of Decimal, ideally), this step should be quick. If not, this is the moment to catch up before the auditors do.

Organize Your Supporting Documents

Auditors don’t just want numbers — they want proof. Make sure every figure in your books can be backed up with documentation. This includes:

• Invoices and receipts
• Bank and credit card statements
• Loan agreements
• Payroll records
• Tax filings
• Contracts and leases

Organize these files by category and date, and store them digitally in a shared drive or your accounting software. The easier it is for auditors to trace a transaction to its source, the faster (and smoother) the process will be.

Review Key Accounts and Adjustments

Before the audit begins, take a closer look at the areas most likely to raise questions. Focus on:

• Accounts receivable and payable aging reports
• Fixed assets and depreciation schedules
• Inventory counts and valuation methods
• Revenue recognition policies

If there were major changes during the year — like a new revenue stream, a merger, or new accounting software — document them clearly. Transparency makes a huge difference.

Evaluate Internal Controls

Auditors don’t just check your numbers — they also assess how you manage them. Internal controls are the systems that protect your business from errors, fraud, or oversight.

Take time to review your processes for authorizations, approvals, and reconciliations. Who handles cash receipts? Who approves expenses? Is there a clear separation of duties? Tightening up internal controls now not only improves audit readiness but strengthens your entire operation.

Prepare Your Team

Audits are smoother when everyone’s on the same page. Make sure your finance and operations teams know what’s coming, what the auditors will need, and where to find information quickly. Assign one point of contact (or partner with Decimal) to coordinate communications and document requests.

That single point of coordination prevents confusion, reduces overlap, and helps maintain a calm, organized flow throughout the audit process.

Turn the Audit Into an Advantage

When it’s over, don’t just file the report away. Your audit results are a goldmine of insight. Look at the findings and recommendations — they can reveal process inefficiencies, documentation gaps, or opportunities for better financial controls.

A clean audit isn’t just a stamp of approval — it’s a sign that your systems are working, your data is reliable, and your business is ready to scale.
