We believe  our duty as accounting professionals is to help maximize your profitability. This can be achieved through identifying areas for revenue growth, or cost reduction.  Our clients consider us an extension of their company. 

Every month we will provide you with clear, concise and easily understood reports and services for your Management, containing critical financial information for your company to make the right decisions.

Management accounting

Let our team of experienced accountants help you build the financial foundations of your business. And our depth of team means that we’ve always got someone to help meet your needs. Our well-trained accounting staff also oversee your vendor payments and WHT deductions to help give you peace of mind.

Corporate set-up

Getting your company set-up properly is the first right decision you must make. You must engage experienced professionals who understand and can advise you with a complete knowledge of best legal structures, and the accounting and tax issues to which you need to conform before you start any new business transactions in Thailand. This includes pros & cons of BOI, various business licenses and regulatory registrations.

Legal Compliance

The Thai legal system  can be a labyrinth. Our experienced, Thai qualified lawyers can help you navigate that maze with greater ease. Our one-stop-shop for legal compliance includes corporate secretarial, obtaining / renewing visas and work permit, ongoing BOI compliance and other regulatory reporting to a wide range of governmental authorities.

Project accounting & CFO services 

Whether you need  advice on the best  structure for your company, financial or tax planning, a company turn-around, credit control, cash recovery, forensic accounting, or internal controls improvements; whatever your query, an experienced CPA (or Chartered Accountant) is just an email or phone call away.

Tax compliance & advice

Tax compliance can be an enormous headache. Our team of experienced accountants will deal with the Thai  Revenue Department, so you won't have to worry about avoidable delays and costly tax filing errors. Otherwise, the resulting tax penalties and surcharges can grow quickly, while any tax refunds can be very slow. Let our team, with our proven track record, give you an advantage. 

Budgeting & Forecasts 

Sometimes the direction to take your business  can be unclear.  Let our team of experienced accountants help you see where your business  is doing  well, and where it’s underperforming.  An effective budgeting system combined  with regular forecasts are essential tools for the success of your business.

Payroll outsourcing

Outsourcing your payroll ensures confidentiality,  discretely managed and paid per your requirements. And we deliver the additional benefit of having an experienced and up-to-date team of Thai accountants, which is very familiar with local regulations and relevant authorities, who are just an email or phone call away.

We have been using Administration Outsourcing’s service and have found them extremely easy to work with. Their staff are very well trained, competent, reliable, and proactive. Their understanding of various types of businesses and their efficient work reflect the rapid development of our business. We also received a great deal of benefit from their financial advice and financial planning services leaving us to concentrate on our main legal work. We would have no hesitation recommending Administration Outsourcing to other businesses.
