How Thai manufacturers win their orders
Relationships first, and the channel is usually a chat app
Thai industrial selling runs on personal relationships maintained through messaging. A purchasing officer sends a drawing or a specification through a chat app to the salesperson they know, and the formal email follows afterwards. The risk is obvious: the negotiation lives on a personal account, and the company sees only the purchase order at the end.
The customer's parent company often decides
In the automotive and electronics supply chains around Chonburi and Rayong, the buying entity in Thailand may be executing a decision taken by a parent group elsewhere. Expect precise documentation, a slow and structured approval, and a supplier audit before volume is committed.
The audit is the real sales meeting
Price gets you quoted; the audit gets you approved. Findings raised on the day become corrective actions, and how quickly those are closed says more about your company to the customer than any presentation.
