What Is an Audit? Answers for Beginners

An audit is the process of verifying the accuracy of the financial statements and supporting accounting documents by a certified public accountant (CPA), to give assurance that the financial information presents the company's financial position correctly under financial reporting standards. If you run a business in Chiang Mai or nearby, understanding this is the most important first step in building transparency and credibility for your business.

Why SMEs in 2026 Must Not Overlook the Importance of an Audit

In the economy of 2026, where information matters more than ever, an audit is not just a tax matter but the core of business sustainability. The reasons you should take it seriously are:

  • Building credibility with financial institutions: if you want to apply for a loan to expand the business, audited financial statements are the most important passport
  • Preventing tax problems: an audit helps detect errors before they become penalties or surcharges with the Revenue Department
  • Accurate tax planning: audited information gives the owner an overall picture of expenses and opportunities for legitimate tax deductions
  • A legal requirement: Thai law requires a limited company to prepare financial statements and have them audited by an auditor before filing them with the Department of Business Development (DBD) every year

If you are looking for an adviser who understands the nature of local business, YMTD's Chiang Mai accounting services will help you manage these matters professionally and greatly reduce the risks that could arise.

The Process: Audit Steps SMEs Need to Prepare For

Many people worry that an audit is complicated, but if your documents are well managed the process runs very smoothly. The main steps are:

  1. Gathering documents: prepare the journals, general ledger, trial balance, tax invoices, receipts and all contracts in full
  2. The auditor's planning: the auditor assesses risk and decides on audit procedures, such as sampling documents, reviewing bank balances or counting inventory
  3. Performing the audit: the auditor checks whether the accounting entries are recorded correctly under accounting standards
  4. Issuing the report: the audit findings are summarized and an opinion on the financial statements is issued. Once cleared, the statements can be filed with the Department of Business Development immediately

For business owners who do not have time to manage documents themselves, getting help from an experienced Chiang Mai accounting service that understands the 2026 tax system will save you a lot of time and reduce errors in gathering documents.

Common Bookkeeping Mistakes for Beginners

From the work of YMTD Accounting Partner, we find that the main problems that hold up an audit usually come from:

  • Mixing personal money with company money: this is the most serious mistake, and it can make it difficult to prove income and expenses
  • Incomplete or lost documents: not filing expense receipts by category means the auditor cannot certify those items
  • Recording entries late: doing the books once a year, or leaving them too long, leads to errors in recording the data

Our Chiang Mai accounting services team is ready to advise you on organizing your documents from the start, so that your business can move forward without obstacles.
