Four Thai rules usually come up for a SaaS company with Thai customers: the PDPA, which reaches offshore providers; the Copyright Act's default that employees own the code they write unless agreed otherwise in writing; the Foreign Business Act once you form a foreign-owned Thai company; and the platform rules if your product is multi-sided.
| Check | Why | Source |
|---|---|---|
| Personal data | Applies to offshore providers serving people in Thailand | PDPA s.5 |
| Code ownership | Employees own their work unless agreed in writing; contractors' work belongs to the client unless agreed otherwise | Copyright Act ss.9, 10 |
| Thai entity | A company 50% or more foreign-owned has its activity checked against the Act's lists | Foreign Business Act s.4, List 3 |
| Platform rules | If the product connects users for transactions | Royal Decree B.E. 2565 |
