Years of Trusted Partnerships & HR Outsourcing Excellence

Our Journey

Professional One has over 40 years of experience in HR outsourcing services. We were the first Thai company to be trusted by leading international IT companies to manage their human resources since 1990, a time when outsourcing policies were just beginning in Thailand. Our expertise in recruitment and selection, accurate and timely payroll processing, long-term employee relations management, and deep understanding of Thai labor law led to us being selected as a key partner in Skilled IT Resource Service Provider in 1997, and we have continued to build trust with leading organizations to this day.

We continuously develop and expand our services to meet the needs of all industries, including Outsourcing, Recruitment, Developer Outsourcing, Visa & Work Permit, and Expat Solutions. We elevate our service standards with ISO 9001, ISO/IEC 20000-1, and ISO/IEC 27001 certifications. Building on this success, we established ProOne IT in 2012 to provide comprehensive IT infrastructure and solutions, committed to supporting your business sustainably.
