Which website does your Bangkok company need?

In Bangkok, your website talks to clients, partners, investors and future hires at once. Start from the result you want to measure, then pick the format.

Four website formats for companies, by goal and by what you measure

How does SEO work in English and Thai?

Bilingual SEO means two sets of pages, not one site with a translate button.

  • One address per language. English and Thai pages each have their own URL, linked by hreflang tags so Google shows the right version.
  • Thai keywords researched in Thai. Thai is written without spaces between words, and people search with their own phrases, such as รับทำเว็บไซต์ for a web design service. Titles and descriptions are written natively, not translated.
  • A solid technical base. Mobile-first pages within Google’s “good” Core Web Vitals, structured data and Search Console set up for both languages.
  • Ready for AI answers. A direct answer at the top of each page, clear FAQs and consistent company details help ChatGPT, Perplexity and Google’s AI Overviews cite you.

Good to know: nobody can guarantee the first position on Google. Rankings are built over time and measured in Search Console.

How do you sell online in Thailand?

A Thai store should accept the methods your customers use. Through Stripe or Opn Payments (Omise), it can take cards and PromptPay, paid in baht by scanning a QR code in a banking app; Opn also supports TrueMoney Wallet, Rabbit LINE Pay and mobile banking. Fees vary by provider and are checked at project time.

Each payment is confirmed by a webhook, a message the provider sends to your server the moment a payment succeeds, so the order is validated even if the customer closes the page. Shopify is the quick route for a classic catalogue; a custom Next.js store makes sense for B2B accounts, specific pricing or a link to your stock system.

How does your site connect to your CRM, LINE and internal tools?

  • Your CRM

    Every form or chat lands in HubSpot, Salesforce or your own CRM, with the source and campaign attached.

  • Your LINE Official Account

    An add-friend button, LINE Login, and order or appointment updates through the Messaging API, scoped with you.

  • Your team

    A new lead or order posts an alert in Slack, Microsoft Teams or WhatsApp, so nobody waits for an answer.

  • Your office tools

    Quotes in Google Sheets or Excel, meetings in Google Calendar or Outlook, invoices in your accounting tool.

When should a website become a web app?

As soon as clients log in, request quotes, follow orders or download documents, you need a web app: a site with accounts, data and business rules. We build customer portals, B2B quoting tools, back-offices and SaaS products with React, TypeScript, Node.js, Python and PostgreSQL.

A recent mission: a customer portal with online quotes for an insurance and services group. Our own product, Madata, a multi-company SaaS ERP on the web, iPhone and Android (case study in French), was designed and deployed end to end by our team. If your users need a phone app, see app development in Thailand.

Frequently asked questions about web design in Bangkok

How long does it take to build a corporate website in Bangkok?

A corporate showcase website is delivered in a few days once the content is ready. An online store or a web app is built in stages, with a first usable version early on, because catalogues, payments and integrations need testing. Jingi Agency sets the schedule and a fixed quote broken down by stage after a free scoping call.

Can you do SEO in both English and Thai?

Yes. Each language gets its own pages, titles and descriptions, linked by hreflang tags so Google shows the right version. Thai keywords are researched in Thai, since Thai is written without spaces between words and people search with their own phrases. We also set up Search Console, structured data and fast mobile pages. Nobody can guarantee the first position.

Which payment methods can an online store in Thailand accept?

Through a provider such as Stripe or Opn Payments (Omise), a Thai online store can accept cards and PromptPay, the QR code payment made in baht from a banking app. Opn also supports TrueMoney Wallet, Rabbit LINE Pay and mobile banking. Jingi Agency helps you choose the provider; fees vary and are checked at project time.

Can the website connect to our CRM and LINE Official Account?

Yes. Forms and chats can create contacts and deals in HubSpot, Salesforce or your own CRM, together with the campaign that brought them. On the LINE side, we can add an add-friend button, LINE Login and order or appointment updates through the Messaging API. Jingi Agency connects these tools through their APIs and documents every connection.

Can you redesign our existing website without losing our Google rankings?

Yes. We audit the current site, keep the content and pages that already rank, and set up permanent 301 redirects that send visitors and search engines from each old address to the new one. After launch we watch Search Console for errors. A redesign is also the right moment to add proper Thai or English pages.

Who owns the website and the code?

You do. The domain, hosting access, source code of a custom site, Google accounts, payment provider account and content are all in your company’s name and handed over with documentation. If you change provider one day, you leave with the whole website. Jingi Agency remains available for maintenance if you want it.
