Chief Financial Officer
Primus Financial is led by Papob Chutrakul, CA — a Registered Chartered Accountant with Australia & New Zealand credentials, TFAC registered in Thailand, and over a decade of corporate accounting and financial management experience.
Papob's background spans Big 4 audit, ASX Top 200 in-house M&A and FP&A, and executive-level finance leadership within some of Thailand's largest corporate groups — giving him a rare combination of international rigour, board-level perspective, and deep local market knowledge that most accounting firms simply cannot offer.
As a multiple start-up founder himself, he understands the scaling journey from the inside — the cash flow pressures, the compliance blind spots, and the financial clarity needed to grow with confidence.

Accounting Manager
Saengphop Kathinthet leads the accounting team at Primus Financial, bringing more than 15 years of experience across both sides of the profession — eight years managing statutory audits and seven years running the full accounting function of a Thai accounting firm. That combination means every set of books he oversees is prepared the way an auditor expects to find it.
As Accounting Manager he owned the general ledger, payables, receivables and fixed assets for a portfolio of client companies, closed the books monthly and annually, prepared full financial statements under Thai Financial Reporting Standards (TFRS), and filed PND, VAT and social security returns alongside the annual PND.50 to the Revenue Department and DBD. He also designed accounting systems, internal controls and production costing for clients and led the team delivering them.
Earlier, as an Audit Manager, he planned and supervised audit engagements from budget and engagement letter through to the auditor's report, working directly with company owners on findings and best practice. Saengphop graduated with first-class honours in Accounting from Ramkhamhaeng University, is a TFAC-registered accountant, and has passed five of the six papers toward his Thai CPA licence.

Client Testimonials
Trusted by businesses
across Thailand
What our clients say about working with Primus Financial.
As a business owner, I rely on their accounting and financial services for their speed and accuracy. Their trustworthy team consistently delivers high-quality results that have greatly enhanced our financial management.
Primus Financial consistently demonstrates a high level of competence, flexibility, and reliability in managing our financial matters. I have complete confidence in Papob, who collaborates closely with our finance team to ensure efficient and seamless execution.
Papob prepares our monthly financial reporting packs for our small business; including key performance indicators, historical financials, and forward-looking forecasts. The reporting packs are what you expect to see in the board pack of a multi-billion dollar company. I would highly recommend his CFO services to any business.
Even though we are a startup, I feel like I'm treated as the biggest and most important client in their portfolio. I can reach out with any question at any time and always receive quick, clear answers. What stands out most is how proactive they are with strategic advice — they truly understand the challenges of starting a business with limited manpower and actively think along with us. Primus Financial operates like a professional Family Office, but with the warm feeling that you're actually part of the family.
Primus Financial has been an essential partner since our pre-opening phase. They helped us get our company structure right from the start and have handled all our monthly accounting, payroll, and tax ever since. It's a huge relief to focus on our operations knowing the compliance side is fully covered. I'd highly recommend them to anyone starting a business in Bangkok.
