What a Retail & e-commerce website needs

01

Product pages that sell

Images, reviews and buy buttons where people decide.

02

Every payment method

Cards, PromptPay and instalments in one place.

03

Membership and points

Points and coupons that bring buyers back.

The short answer

Does an online shop need its own website if it already sells on Shopee and Lazada?

Yes. Marketplaces help people find your products, but your own site lets you own customer data, set prices and offers freely, avoid competing with other sellers on the same page, and build membership that brings buyers back. A good store has clear product pages, a short checkout with cards and PromptPay, connected stock and shipping, and sales tracking from ads.

How Thai online shoppers search and decide in 2026

Thai e-commerce is growing fast. Momentum Works reported that platform e-commerce sales in Thailand grew 51.8% year on year in 2025. Most of that happens on big marketplaces and through video selling: many shoppers first see a product in a short clip or live stream, then search the brand name to read reviews and compare prices.

This is where a brand website matters. When shoppers search your brand on Google, they want an official-looking site with full product details, a clear returns policy and real contact options. The site is both a shop and proof that the brand is real.

Repeat buyers are usually the most profitable group, because you don’t pay full ad costs or platform fees every time. Moving customers from marketplaces to membership on your site or friends on your LINE OA is a long-term goal worth planning for.

Must-have pages and features

The product page is the most important page in an online store. It needs images from several angles, clear sizes or specifications, price, colour and size options, stock status, reviews and a buy button visible straight away on a phone. Shipping cost and delivery time belong near the buy button, because they are what makes people hesitate most.

Checkout should be as short as possible: allow guest checkout, remember addresses for next time and show the full total including shipping before the final step. Every extra step is another chance for a customer to abandon the cart.

  • Category pages with filters and search
  • Product pages with images, details, reviews and stock
  • Cart and a short checkout
  • Member accounts, order history, points and coupons
  • Shipping, returns and privacy policy pages
  • Order tracking page

Integrations that matter in Thailand

For payments, Thai shoppers expect credit and debit cards, PromptPay QR and, for higher-priced items, instalments. All of this is available through a payment gateway that serves Thailand. Payments should be confirmed automatically, not by asking customers to send a transfer slip and wait for an admin to check it, which is slow and error-prone.

Behind the scenes, connect to couriers so tracking numbers are created automatically, and sync stock between the site, marketplaces and any physical shop so you don’t sell items that are gone. For marketing, install Meta Pixel with Conversion API, Google Analytics 4 and Google Merchant Center so products can appear in Google Shopping, and use LINE OA for order updates and member offers.

Content, SEO and AEO for online stores

Don’t use manufacturer descriptions or copy that matches other sellers on marketplaces. Write your own in the brand’s voice and answer the questions customers ask most: how does the size run, what does it work with, how do I care for it. Original content like this helps both sales and search rankings.

Category pages should carry a short text explaining who the range is for, and product pages should use Product structured data with price, stock and review rating so Google and AI tools read them correctly. Buying guides and model comparisons are the kind of content AI assistants tend to draw on when someone asks what to buy.

Trust and legal points to watch

Online shops in Thailand are generally expected to register as e-commerce businesses with the Department of Business Development (DBD), and can apply for a trust mark to display on the site. Show your registered business name, address and clear contact details, plus a returns policy that is easy to understand. Check the latest requirements with the DBD before you launch.

Stores collect a lot of personal data, including names, addresses, phone numbers and purchase history, so PDPA applies: a cookie banner with real choices, separate consent for marketing messages, and never storing card details yourself. Leave card handling to a payment gateway that meets security standards.

How to measure results

The core numbers for a store are revenue, conversion rate, average order value and repeat purchase rate. Then look at where people drop out most: viewing products without adding to cart, or adding to cart without paying. Each point has a different fix.

For ads, track return on ad spend (ROAS) based on real sales, which depends on a correctly installed Pixel and Conversion API. Compare the cost of winning a new customer with what that customer spends over time. That tells you how much you can spend on ads and still make a profit.

Common mistakes

Many stores spend on ads before product pages and checkout are ready, paying to send people to a site that is hard to buy from. Another problem is a site that looks good on a computer but is awkward on a phone, where most shoppers actually buy.

Another thing often overlooked is the experience after purchase. Stores that don’t share delivery status, reply slowly or make returns hard lose customers who might have come back, and collect reviews that make new shoppers hesitate. Store design has to cover the whole journey, from first seeing a product to receiving it.

  • Accepting only bank transfer with a slip
  • Hiding shipping cost until the last step
  • Website stock that doesn’t match real stock
  • Using the same images and copy as other marketplace sellers
  • No way to keep customer details to bring them back

A realistic launch roadmap

A store with a modest range on a ready-made platform can often launch in about 6 to 8 weeks. Stores with hundreds of products, stock synced to back-office systems or complex membership usually take 10 to 16 weeks. Preparing product data and photos nearly always takes longer than expected, so start on day one.

Don’t launch with full ad spend on day one. Use a small budget for the first two to four weeks to confirm payments, notifications and shipping all work, then scale up once you are confident. Big sale dates such as 11.11 or 12.12 are a bad time to switch on a new store; launch several weeks before.

  • Weeks 1–2: choose the platform, plan categories and start product data
  • Weeks 3–5: design home, category, product and checkout pages
  • Weeks 5–8: build and connect payments, shipping, stock and tracking
  • Before launch: place real test orders with every payment method
  • After launch: add ad channels one at a time and adjust from real data

Frequently asked questions

Is selling only on marketplaces enough?

It is enough to start, but it has long-term limits. You don’t own the customer data, you pay fees on every order and you compete on price with similar sellers on the same page. Most stores that grow steadily use both: marketplaces to find new customers, and their own site and LINE OA to bring existing customers back.

Should we use a ready-made platform or build a custom store?

Most stores do well starting on a ready-made platform: it launches quickly, has payments and shipping built in and is easy to run. A custom build makes sense for specific needs, such as ERP integration, tiered wholesale pricing or complex membership. Choose based on what the business will need in two to three years, not just on launch day.

Do we need to accept PromptPay?

Yes. Many Thai shoppers are used to scanning a PromptPay QR, and some don’t use credit cards. The key is automatic confirmation through a payment gateway, not asking customers to transfer and send a slip for checking. Automatic confirmation gives customers instant reassurance, cuts admin work and lowers the risk of fake slips.

What is Conversion API, and do we need it?

Conversion API sends purchase data from your site’s server straight to the ad platform, instead of relying only on the browser pixel, which can be blocked or miss events. With more complete data, the ad system learns better and you see ad-driven sales more accurately. For stores that advertise regularly, it is essential.

How do we get customers to buy again?

Start with a good first experience: on-time delivery and clear status updates. Then invite people to join membership or add your LINE OA with benefits that matter, such as points, birthday coupons or early access to new products. Send messages based on behaviour, like a reminder when a regular item is likely running out, instead of the same promotion to everyone.

What do we need to register before opening an online store?

In general, online sellers in Thailand need to register their e-commerce business with the Department of Business Development, and may need to register for VAT once revenue reaches the legal threshold. Some products, such as food, cosmetics or supplements, also need approval or notification with the Thai FDA. Check with the relevant agencies or a legal and accounting adviser before you start selling.

How much do product photos matter?

A lot. Online shoppers can’t touch the product, so photos have to do that job. Include several angles, a shot that shows scale next to a person or object, close-ups of materials and photos of the product in use. Short videos help a great deal for items that need to be seen moving, such as clothes or appliances, as long as files are compressed to load fast on a phone.

Do we need a mobile app as well?

Most stores don’t yet. A mobile-first website plus LINE OA covers most needs. An app suits stores with many regular customers who buy often and need features the web handles less well, such as an in-store membership card or targeted notifications. Get a website that sells well first, then consider an app once your data supports it.

When will a new store start getting sales from Google?

From organic search, it usually takes several months, depending on competition in your category and the quality of your content. Google Shopping ads through Merchant Center can bring sales much sooner if product data is complete and accurate. A common approach is to use ads early while building content and SEO to rely less on paid traffic over time.
