About us
Kingdee ERP partner in Thailand — Siamrajathanee (SO)
Siamrajathanee Public Company Limited is a full-service outsourcing and digital transformation provider. Back-office work is our profession, not a side business, so we design Kingdee ERP projects that do not end on handover day.
Our story
Over 50 years of keeping business operations running every day
Siamrajathanee has served Thai organizations for more than 50 years, covering workforce management, corporate car rental with drivers, landscaping, industrial waste management and digital services under SO NEXT.
Today we are listed on the Stock Exchange of Thailand under the ticker SO, managing more than 200,000 staff and over 10,000 vehicles in service. That experience means we understand both the front line and the numbers in the books.

Why Kingdee comes with SO
Software alone is not enough — someone must be accountable for results
Kingdee Cloud ERP is widely used by fast-growing companies across Asia. What makes it work for Thai organizations is process design, approval rights, integration with existing systems and a team that supports you after go-live.
So SO is not just an installer but a partner that stays with you from the first assessment until the system is part of daily work. If your internal team is not ready, we can also run operations on the system for you.
- On-site assessment before proposing scope and price
- Demos on your real business processes
- Role-based user training, not just screen walkthroughs
- A support team, plus the option to outsource operations
