If your company has just crossed the threshold where an independent audit is required, the first one is usually the hardest. The problem is not that your numbers are wrong. It is that auditors ask for evidence you never had to organize before. This guide walks through exactly what to prepare, in what order, and where first-time clients lose time. By the end you will know how to make the audit faster, cheaper, and far less stressful.

Why the First Audit Feels Different

An independent audit is not a tax inspection and not a bookkeeping review. The auditor’s job is to gather enough evidence to give an opinion on whether your financial statements are fairly stated. That means they test balances against source documents, confirm items with third parties, and check that your accounting follows Vietnamese Accounting Standards (VAS) and Circular 200/2014/TT-BTC.

The difference from internal accounting is the burden of proof. Your books may be correct, but if you cannot produce the contract, the bank confirmation, or the fixed-asset list behind a number, the auditor cannot rely on it. First-time clients underestimate how much of an audit is document retrieval, not accounting.

What to Prepare, in Order of Priority

1. Closed and reconciled books

Before the auditor arrives, close the period. Cash and bank must reconcile to statements. Receivables and payables sub-ledgers must tie to the general ledger. If your trial balance does not balance, everything downstream slows down.

2. Confirmation-ready lists

Auditors send confirmation letters to banks, major customers, suppliers, and sometimes lenders. Prepare a clean list with names, addresses, and outstanding balances early. Third parties are slow to reply, so this is the item that most often delays the report.

3. Fixed assets and inventory

Have a fixed-asset register with acquisition dates, cost, and depreciation. For inventory, a physical count near year-end with count sheets is strong evidence. If you missed the count, tell the auditor immediately so they can plan an alternative.

4. Contracts and legal documents

Business registration, major sales and purchase contracts, loan agreements, and lease contracts. These support revenue recognition, liabilities, and related-party disclosures.

A Realistic Timeline

Stage	Timing	Your task
Planning	4-6 weeks before deadline	Sign engagement, agree scope and fee
Document request	3-4 weeks before	Send confirmation lists, close books
Fieldwork	1-2 weeks	Answer queries, provide source documents
Review and report	Final week	Confirm adjustments, sign off

A Real Scenario

A trading company came to its first audit with tidy software records but no filing system for contracts. When the auditor sampled ten sales, the accountant had to search email threads for each contract and delivery note. Fieldwork that should have taken five days stretched to two weeks, and the fee rose because of the extra hours. The next year, the same company kept a shared folder organized by voucher number. The audit finished in four days. Nothing about the accounting changed. Only the retrievability did.

Common Mistakes and How to Fix Them

• Treating the auditor as an enemy. Withholding information invites more testing. Fix: be transparent early, especially about known problems.
• Sending confirmations late. Third-party replies control your timeline. Fix: send them the moment books close.
• No revenue cut-off discipline. Recording December sales in January, or vice versa, is a classic finding. Fix: match revenue to the delivery or service date, not the invoice or payment date.
• Mixing personal and company transactions. Common in SMEs and a red flag for auditors. Fix: separate accounts and document any owner transactions as loans or capital.
• Assuming tax books equal financial statements. VAS and tax rules differ, for example on some provisions and depreciation. Fix: understand where they diverge instead of forcing them to match.

Pre-Audit Checklist

• Trial balance closed and balanced
• Bank reconciliations for all accounts
• Receivable and payable aging tied to the ledger
• Fixed-asset register with depreciation
• Inventory count sheets
• Confirmation list with addresses and balances
• Major contracts filed and retrievable
• Prior-year financials and tax returns
• A named contact person available during fieldwork

Conclusion and Next Step

Your first audit is mostly an exercise in organization. If you close the books, prepare confirmations early, and keep source documents retrievable, you remove the friction that inflates both time and fees. The next concrete step: build a folder structure indexed by voucher number now, before fieldwork, so every number has its evidence one click away.

Frequently Asked Questions

How long before the deadline should I appoint an auditor?

Ideally four to six weeks, and earlier if it is your first audit. Confirmations and document gathering take longer than expected, and reputable firms book up near year-end deadlines.

Will the auditor also handle my tax filing?

Not automatically. Audit and tax are separate services. Many firms offer both, but the audit opinion covers the financial statements, not your tax compliance. Agree the scope in writing.

What happens if the auditor finds errors?

They propose adjustments. You can correct the books, which usually preserves a clean opinion. Refusing material corrections can lead to a qualified opinion, which lenders and investors read as a warning.

Can I reduce the audit fee?

Yes, mainly by being prepared. Fees rise with the hours spent chasing documents and resolving queries. Clean, retrievable records are the most reliable way to keep the fee down.
