Words of praise from our clients


Great experience, the team help me to digitalize all my accounting processes by scanning all my documents by using Artificial Intelligence Technology to detect and sort document types and amounts. Then they provide me with a Cloud-based Accounting Software linked directly to my CRM. And finally, they set up some automation processes in order to manage and follow up the invoices & payments automatically.

Business Owner


All I can say is great. I'm happy with the accounting service. Thanks to their advice and recommendation, I learned a lot about how to optimize my business and cashflow. I've taken the recommended steps to shift to an analytics accounting style thanks to their cloud-based accounting software that's put the autonomy in my team, and regained their trust. Our productivity is much better now.


Have Questions? We Have Answers.

What is the withholding tax?

Basically, it is the practice of deducting tax from payments to service suppliers, payment of dividends, and payments of interest of THB 1,000 or more. To fully comply with Thai tax laws, withholding tax must be paid first by the person or company making the payment, a withholding tax certificate must then be provided when such a payment is made. This means that the service provider as part of its corporate income tax already paid. At the end of the financial year, withholding tax deducted in payments to a service provider constitutes a tax credit of the corporate income tax of the service provider for the following year.

Why outsource the bookkeeping tasks?

Starting a business is challenging and success may be easier achieved if the management focuses on the core business and outsource bookkeeping to a firm with Certified Public Accountants (CPA) who are knowledgeable of the latest accounting practices in Thailand.

Do you provide any Accounting Software?

Thai accounting rules and regulations are very specifics. That's why instead of trying to adapt to some leading accounting software such as Xerox or Zoho Book. We provide a Cloud-Based Thai Accounting Solution compliant with Local Accounting Rules and Regulations. You can connect your CRM or ERP with our API.

Do I need to pay the corporate income tax?

Companies and partnerships established under Thai laws are subject to income tax on income earned from within and outside of Thailand. Companies and partnerships required to pay income tax include, but are not limited to limited companies, registered ordinary and limited liability partnerships, joint ventures, foundations and associations and a branch of a foreign corporation earning from sources within Thailand. 

What about Digital Transformation and Accounting?

As a leading Tech Accounting Company, we can help you to digitalize your accounting process by implementing a Document Dematerialization process, Cloud Accounting, Automation process, Data Analytics, Artificial Intelligence, Blockchain integration and Interoperability.

Do I need to pay the VAT?

The Value Added Tax (VAT) registration is required for all businesses that reach a sales volume of THB 1.8 million. Currently, the rate is 7%, which is reduced from the nominal rate of 10%. VAT returns must be filed and paid within 15 days of the following month.
