How Much Does a Website Cost in Thailand? What Actually Drives the Price

The first question almost everyone asks is "how much does a website cost", and the honest answer is that nobody can tell you until they know the scope — it is like asking the price of a house without saying how many rooms, how many floors, or what land it sits on.

What you should know before talking to any agency is what actually moves the number, so you can compare quotes fairly and not overpay.

The 7 real cost drivers

1. Page count and structural complexity

A five-page company profile and a fifty-page site with product categories, search, and an article system are different orders of work. Price follows.

2. Custom design or a template

Templates are always cheaper because the design work is already done — the trade is a site that looks like everyone else's. Designing to your brand takes longer but produces something competitors cannot copy.

3. Systems you need to connect

A standalone site and one wired into LINE OA, payments, CRM, inventory, or accounting are not the same job. Every integration adds testing and long-term maintenance.

4. Content — who writes it

If your content is ready, the price drops. If the team writes it from scratch, it rises. And bilingual Thai–English doubles the writing.

5. SEO / AEO from day one, or bolted on later

Building schema, speed, and content architecture in from the start costs slightly more up front and far less than retrofitting it after launch.

6. AI-native capability

A site with a vectorized knowledge base (RAG) so an AI agent answers customers from your real data, voice support, and MCP so the site can be operated by an AI is additional engineering over a standard build — and it is what makes the site work for you around the clock rather than sit there as an online brochure.

7. Care after launch

A website is not finished on launch day. Maintenance, hosting, security updates, and ongoing improvement belong in the quote from the beginning, not as a surprise later.

Timelines worth expecting

The standard engagements we actually run at TecTony:

• Websites — 6–10 weeks from kickoff to launch
• LINE OA / LIFF / chatbot systems — 4–8 weeks to first launch
• Your first working AI system — 4–8 weeks
• 3D work — 3–6 weeks per set

If someone offers a finished corporate site in three days, ask which template it uses and who maintains it afterwards.

Questions to ask any agency before signing

1. What is included in this price — and what is not?
2. Who owns the code and the domain after handover?
3. Can we edit content ourselves, or do we pay for every change?
4. Does it ship with Schema / JSON-LD and an llms.txt for AI engines?
5. Can this site support RAG or an AI agent later, or would it need rebuilding?
6. What is the monthly maintenance fee and what does it cover?
7. If we leave, can we take the site with us?

Why we do not post fixed prices

Because a headline price is only ever one of two things: inflated to cover the worst case, or lowballed to get you on the phone before the extras appear. Neither is fair to you.

We would rather discuss scope first and then give you a number that holds — a free consultation, with no obligation.
