Web Design Thailand: Custom Bilingual Websites for Thai Businesses

Short answer

A custom bilingual (Thai/English) website from ฿12,900, paid once. You own the site outright: no monthly fee, no setup fee, live in 2–4 days, and every page designed around your business rather than a template with your logo dropped in.

94.7%

of people in Thailand are online (67.8M) — your site is judged in seconds, on a phone.

of the population holds a social account (56.6M) — customers compare you on social before they click.

Most "cheap website" deals in Thailand are recycled templates that look like every other shop on the street. The expensive end quotes you tens of thousands of baht upfront with nothing promised in return. WebSiam sits in between: a genuinely custom, done-for-you website in both Thai and English, at one fixed price you agree to once, with the site owned by you.

We build for how Thai customers actually buy. They search Google for your service, they message you on LINE, they pay with PromptPay, and they do all of it on a phone. Your site is shaped around that from day one. The English reads cleanly for expats and tourists. The Thai is written by people who actually speak it, never run through a translation engine.

What you get

Custom design, not a template

Every page is built around your brand, your services, and your customers. No off-the-shelf theme that ten other Bangkok businesses are already running. Your site looks like you, sounds like you, and sells because it matches how you actually win customers.

Real Thai and English, done right

Two proper languages, written by humans, with correct hreflang so Google shows the right version to each visitor. Tourists, expats, and medical-tourism patients get clean English; Thai customers get natural Thai. No clumsy Google Translate.

Nisa, your 24/7 AI concierge

A built-in trilingual chatbot (Thai, English, French) answers questions and captures leads day and night, including the late-night and weekend enquiries that usually slip through. It's LINE-ready, so it meets buyers on the app most Thais already live in.

Live in 2-4 days

Most WebSiam sites go live within two to four days. No waiting weeks for a quote and months for a launch. You send us your details, we build it, you review it, and you go live and start getting found.

You own everything

Your domain, your content, your site. No platform lock-in, no holding your business hostage. If you ever want to walk away, you take all of it with you, which is the opposite of how template builders keep you stuck.

Managed hosting plus local SEO

Secure hosting with SSL and automatic backups is handled for you, so no surprise renewal or downtime bills land on your desk. We set up local SEO so you show up when someone searches your service plus your city, from Bangkok to Phuket, Pattaya, and Chiang Mai.

Templates and freelancers vs a custom WebSiam site

The Thai market splits into two painful extremes. At the bottom, template shops sell ready-made sites that look identical to the competition and rank for nothing. At the top, agencies quote ฿50,000 to ฿150,000 and more, a heavy bill for a small business with no promise of results. In the middle sit freelancers, and Pantip is full of stories of deposits taken and people who vanish before launch.

WebSiam is the middle path that should have existed all along: agency-grade custom work from ฿12,900, a Bangkok team that actually answers, and one fixed price instead of a bill that keeps growing. You own the site outright. The first year of care is included, and after that a yearly fee covers hosting, SSL, backups and security updates — nothing hidden, nothing automatic you didn't agree to.

  • Template shops: cheap, generic, invisible on Google, and not truly yours
  • Big agencies: large upfront fee, slow, risky for a small business
  • Freelancers: deposit risk, ghosting, half-finished work, no support after launch
  • WebSiam: custom build, Bangkok team, live in 2–4 days, owned by you, one fixed price

Built for how Thailand buys: LINE, PromptPay, mobile-first

Most Thais use LINE, and many shoppers chat with a business there before they ever open its website. If your enquiries die somewhere between a LINE message and a follow-up, qualified buyers just walk. Nisa, your AI concierge, catches those leads automatically and keeps the conversation going at 2am.

PromptPay is now a default way to pay across Thailand, and almost every Thai visitor arrives on a phone. So we design mobile-first and fast, with easy PromptPay QR on commerce sites, instead of heavy, slow homepages that visitors abandon and Google holds back under mobile-first indexing.

  • LINE-ready chat and lead capture, where your customers already are
  • PromptPay QR built in for shops and bookings
  • Mobile-first, fast-loading pages designed for Thai smartphone users

Plans for every kind of Thai business

Pick the plan that fits where your business is now. Launch (฿12,900) is a sharp one-page site for solo owners and new businesses that need to get found on Google and LINE fast. Local Growth (฿29,900) is our most popular: up to five custom pages with local SEO and AI chatbot preparation. Commerce & Booking (฿49,900) adds a catalog or booking structure with Thai payment setup. Every plan includes the first year of care, and you own the site from day one.

  • Launch ฿12,900: one-page site, get found on Google + LINE
  • Local Growth ฿29,900 (most popular): up to 5 pages, local SEO
  • Commerce & Booking ฿49,900: catalog or booking, Thai payments
  • Tailored (quote): property portals, 10+ product e-commerce, custom builds

Frequently asked questions

How much does a website cost in Thailand with WebSiam?

Launch is ฿12,900 for a one-page site, Local Growth is ฿29,900 for our most popular plan (up to five pages), and Commerce & Booking is ฿49,900 with a catalog or booking structure. Each is a one-time price and the site is yours. The first year of care is included; after that it renews from ฿3,900 a year for hosting, SSL, backups and security updates. Bigger or more custom projects, like a property portal or a store with 10+ products, get a Tailored quote.

Who owns the website and the domain?

You do, completely. Your domain, content, and site belong to you, with no platform lock-in. If you ever decide to leave, you take everything with you. That's the opposite of template builders that trap your business inside their system.

Do you build websites in both Thai and English?

Yes, bilingual Thai/English is what we do best. Both languages are written by people, not Google Translate, with proper hreflang so Google shows the right version to each visitor. It works well for businesses serving Thai customers alongside expats, tourists, and medical-tourism patients.

How fast can my website go live?

Most WebSiam sites are live within 2 to 4 days. You send us your details and content, we build the custom design, you review it, and we publish. No waiting weeks for a quote or months for a launch.

Can you handle edits for me after launch?

Yes. A Bangkok-based team handles your changes, so you never have to learn anything technical. Local Growth includes five edits a month and Commerce & Booking includes unlimited edits, with no slow, paid, per-change runaround.

Will my site rank on Google and work with LINE?

Yes. We set up local SEO so you get found when people search your service plus your city, whether that's Bangkok, Phuket, Pattaya, or Chiang Mai. Your site is LINE-ready, and Nisa, the built-in AI concierge, captures leads from chat around the clock.
