The Risk Every Bangkok Accounting Firm Faces

Your team is using ChatGPT to:

The consequences are severe:

  • ฿20 million in PDPA fines
  • Loss of client trust and reputation damage
  • Professional liability and negligence claims
  • Regulatory sanctions from the Federation of Accounting Professions
  • Criminal liability for executives under PDPA Section 79
