E-commerce Website Development Thailand: Online Stores That Sell
Services · Southern Whale
E-commerce website development in Thailand on WooCommerce, Shopify or a custom build, with PromptPay and card payments, Thai shipping, product-level SEO, and store migrations that keep your Google rankings. Designed for your approval first.

A store with a cart vs a store that sells
Most online stores that don’t sell aren’t missing a shopping cart. Every platform has one from day one. What’s missing is the path between seeing a product and paying for it.
- Can’t be found: product pages have no structure Google can read, so shoppers searching the product name find someone else
- Not trusted: no reviews, no shipping information, no reason to believe the order will arrive
- Hard to pay: customers transfer money and send a slip on LINE, and half give up on the way
- Slow: product pages load slowly on mobile, so shoppers leave before seeing the price
So we don’t start by picking a theme. We start by finding where your customers drop off, then build the store to fix that.
Platforms we build on
We’re not tied to one platform; we choose based on your store’s size and how much you want to control.
| Platform | Best for |
|---|---|
| WooCommerce | Stores that want to own the system: no per-order fees, unlimited customisation, every Thai payment method, finer SEO control. Suits catalogues from dozens to thousands of products |
| Shopify | Stores that want to launch fast without managing a server, in exchange for monthly fees and transaction charges |
| Custom build | Special requirements such as tiered wholesale pricing, multi-vendor marketplaces, or integration with existing back-office systems |
For a detailed comparison, read our e-commerce platform guide.
What a Thai online store needs from day one
- Payments Thai customers actually use: PromptPay QR with automatic confirmation, cards and mobile banking through licensed payment providers, so nobody has to send or check transfer slips
- Accurate shipping costs: by weight, by zone or free over a threshold, connected to the carriers you already use
- Proper documents: receipts and tax invoices from the system, plus guidance on Thailand’s e-commerce registration and the DBD Registered trust mark
- The channel customers use to ask: a LINE button on product pages, because many Thai shoppers want to ask before paying
Product-level SEO
A store with hundreds of products only gets customers from Google when every product page is built to be found, not just the homepage.
- Readable product and category URLs, not random numbers
- Product schema so price, stock status and reviews can appear in search results
- Category pages with real content, not just a grid of photos
- No duplicate pages from colour, size and sort filters, the most common reason online stores lose rankings
- Fast mobile pages, since most shoppers buy on their phones
Migrating your store without losing rankings
Many stores come to us to leave their current platform: off a website builder, from Shopify to WooCommerce, or onto their own site after years on Shopee and Lazada. A badly handled migration is where Google rankings disappear overnight, so we always:
- List every old URL: products, categories and pages that get Google traffic
- Map old URLs to new pages one by one and set 301 redirects, never everything to the homepage
- Move products, customers and order history, then check everything is complete before launch
- Launch during a quiet sales period and watch Search Console afterwards to catch any page that slips
Real example: we moved a 1,576-product genuine-parts store off iGetWeb to WordPress with 301s for all 3,274 old link IDs. Read the catalogue migration case study. For catalogues with thousands of SKUs, see our catalogue migration and technical SEO service.

When we might not recommend a website yet
- You’re just starting and don’t know what sells yet. Test on a marketplace first, then build a site once you know your best sellers.
- You have a handful of products and sell mostly through chat. A LINE shop may be enough and cheaper.
- You expect instant sales with no plan to bring visitors. A site nobody sees sells nothing, so plan SEO or ads alongside it.
We’ll tell you honestly in the first conversation which way your store should start.

Frequently asked questions
How much does an e-commerce website cost in Thailand?
It's quoted after we review the scope. The cost depends on the number of products, the platform, and what needs connecting, such as payments, shipping, stock or a migration from your current store. We review your store first, quote a written scope, and design the key pages for you to see before you commit.
How long does it take to build an online store?
A store with a modest catalogue on a standard WooCommerce setup takes less time than one that needs a data migration or custom features. Typically a few weeks to two or three months; we estimate after a short brief.
Should we use WooCommerce or Shopify?
WooCommerce suits stores that want to own the system, customise deeply and avoid monthly platform fees. Shopify suits stores that want to launch fast without managing a server. We help you choose based on store size, team and sales plans.
Are there per-order fees?
With WooCommerce the website takes no per-order fee; you only pay your payment provider's rates. That's different from marketplaces, which take a share of every sale.
Can we update products ourselves?
Yes. We hand over an admin where you add products, change prices and manage orders, with a manual and training.
Can you migrate our store from a website builder or Shopify?
Yes, from any platform. We collect every product and old link, move products, customers and orders, and set page-to-page 301 redirects so the rankings you've built don't disappear.
