Our Story

Built for growth,
shaped by decades.

PTNP Accounting was founded with a single mission: give businesses in Thailand access to reliable, professional accounting they can trust. From our first clients in the 1980s to the growing companies we serve today, that mission has expanded — from compliance alone to active tax planning.

"We have helped businesses in Thailand through every economic cycle for over four decades. Accuracy keeps you compliant. Good advice keeps you profitable."

Today, PTNP is one of Bangkok's most trusted accounting partners — working with restaurants, hotels, trading companies, and established businesses that want more than a bookkeeper.

Common Questions

About PTNP — FAQs

PTNP Accounting is a Bangkok-based accounting firm founded in the 1980s. We specialize in four core areas: monthly bookkeeping and tax compliance, year-end financial statements and audit, business registration services, and accounting system set-up for Thai and foreign-owned companies. Our team holds CPA (Certified Public Accountant) and TA (Tax Auditor) licenses issued by Thai regulatory bodies, authorizing us to certify financial statements and corporate tax returns. We serve a wide range of industries — including restaurants, retail, hospitality, trading companies, and SMEs — across Bangkok and the surrounding areas. Communication is available in both Thai and English, making us a practical choice for foreign investors and expatriate business owners. Our office is located at 187/47 Songprapha 24, Don Mueang, Bangkok, and we also serve clients remotely via LINE, email, and phone.
Yes. All audit work at PTNP Accounting is handled by accountants holding active CPA (Certified Public Accountant) or TA (Tax Auditor) licenses. CPA licenses are issued by the Federation of Accounting Professions (FAP) in Thailand and authorize the holder to certify financial statements for submission to the Department of Business Development. TA licenses are issued directly by the Revenue Department and authorize certification of corporate tax returns, including PND.50 and PND.51. Both licenses require ongoing professional development and renewal. This means your financial statements, tax filings, and compliance documents are reviewed and certified by professionals who are legally accountable for their accuracy — not outsourced or handled by uncertified bookkeepers. For businesses subject to statutory audit requirements, our licensed auditors fulfill all mandatory certification requirements under Thai law.
PTNP Accounting works with businesses across a broad range of industries in Bangkok and across Thailand. Our regular clients include restaurants and food and beverage outlets, retail shops, hotels and hospitality businesses, import and export trading companies, manufacturing firms, professional service providers, and general SMEs at various stages of growth. We also serve foreign-owned businesses and companies with mixed Thai and foreign shareholders, including those navigating the Foreign Business Act or applying for BOI promotion. Our team is experienced with the specific compliance requirements of each sector — for example, the import documentation needed for trading companies or the payroll complexity of hotels with large hourly staff. If you are unsure whether we have experience in your specific industry, we welcome a free introductory conversation with no obligation.
Yes. PTNP Accounting provides fully bilingual service in Thai and English across all of our core service areas — monthly accounting, year-end filing, and company registration. Our team communicates in both languages via phone, email, LINE, and in-person meetings. All standard documents we prepare — financial statements, tax forms, company registration papers — are Thai-language as required by law, but we translate and explain everything to English-speaking clients clearly and without jargon. This bilingual capability makes us a practical choice for foreign investors, expat business owners, and multinational companies operating in Thailand who need a reliable accounting partner that bridges the language gap. We have worked with clients from Europe, North America, Japan, China, and across Southeast Asia. The initial consultation is free and available in English or Thai, whichever you prefer.
Our office is located at 187/47 Songprapha 24, Don Mueang, Bangkok 10210 — in the northern part of Bangkok, conveniently accessible from Don Mueang Airport and major roads in the area. Office hours are Monday to Friday, 8:30 AM to 5:30 PM. Walk-in clients are welcome during office hours, though we recommend contacting us by phone or LINE in advance so we can ensure the right team member is available to assist you. For clients outside Bangkok or those who prefer remote service, we operate fully online — documents can be shared via Google Drive, LINE, or email, and consultations are available by phone or video call. We serve businesses across Thailand remotely and meet Bangkok clients in person when needed. To reach us, call +66-97-293-3932 or email panida.ptnp.acc@gmail.com during business hours.
