Looking for audit & assurance services in Thailand?
At SiamConsult, we deliver clear, compliant, and client-focused audits that protect your business and boost your financial credibility.

What is an Audit?

An audit is an independent examination of your company’s financial statements and records.
Thai law requires nearly all registered businesses to complete this process. Audits are designed to ensure your accounts are accurate and meet all legal standards.

They also help you withstand scrutiny from the Thai Revenue Department and other official authorities, such as the Department of Business Development (DBD) and the Federation of Accounting Professions of Thailand (TFAC).

A well-managed audit not only protects you from penalties and surprises. It also provides valuable insight into your business’s true financial health.
You gain the tools to build trust with partners, banks, and investors.

Why Due Diligence Matters

If you’re planning to invest, acquire a company, or enter a new partnership in Thailand, due diligence is essential.

Our thorough Due Diligence services in Thailand uncover legal risks, financial realities, and hidden liabilities – in advance!
This is also a form of audit, which helps you protect your investment and make confident, informed decisions before signing any binding contracts.
