Ecommerce websites that take PromptPay, cards and COD across Thailand

We build ecommerce websites on Shopify or WooCommerce for businesses selling in Thailand. The E-commerce package starts from THB 50,000 as an indicative one-time price.

The package covers the parts that decide whether a Thai customer finishes checkout: PromptPay, card payments, cash on delivery, shipping through Thai couriers, product import and e-Tax invoice setup. Your staff get training and the store goes live against a written launch checklist.

Which platform comes first is your call, and we help you make it with the trade-offs laid out below. If you already know you want a hosted store with a large app market, our work as a Shopify developer in Bangkok is covered on its own page. If you want full control over the code and your data, or you already run a WordPress site, read how we approach WordPress WooCommerce stores.

Who this is for

• Sellers on Shopee, Lazada, LINE or Instagram who want a store they control, with their own customer list and no marketplace rules on layout.
• Shops that started on a simple store builder and now need proper shipping rules, variants, or Thai and English product pages.
• Brands and distributors that sell to both consumers and trade buyers and want one catalogue for both.

Your own store rarely replaces the marketplaces. For most Thai sellers it works as one channel in a mix: Shopee and Lazada bring buyers who search there, while your own site gives repeat customers a direct place to order, keeps their contact data with you under your own PDPA notice, and lets you run your own offers without a marketplace commission on every sale.

Thai shoppers expect to pay the way they pay everywhere else, and a store that only takes cards loses a share of them at the last step. We set up three routes on every store and put a test order through each one before launch.

PromptPay QR

PromptPay is Thailand's national payment system, and its QR code can be scanned by almost any Thai banking app. On the store, the buyer sees a QR at checkout, pays from their phone, and the order is marked paid when the gateway confirms it. The key choice is whether confirmation is automatic through a gateway or manual, with staff checking a bank app. Automatic is worth it once you have more than a handful of orders a day.

Cards

Visa, Mastercard and other cards go through a payment gateway that holds the card data, so your store never stores card numbers. Which gateway suits you depends on your platform, your company registration and the fees you are quoted. Our guide to choosing among payment gateways in Thailand walks through what to ask each provider. We do not quote gateway fees here because they change and are often negotiated.

Cash on delivery

COD still matters for first-time buyers outside Bangkok and for anyone wary of a new shop. It adds work: couriers collect the cash and remit it later, and refused parcels cost you a return trip. We set COD as a payment option with rules you choose where the platform or an add-on supports them, such as a maximum order value or COD only in certain provinces, so it helps sales without becoming a loss.

If your company is registered for VAT, trade and corporate buyers will ask for a full tax invoice, and many will want it electronically. Thailand's Revenue Department runs an e-Tax Invoice system that lets VAT-registered businesses issue tax invoices and receipts in electronic form, with more than one route depending on the business. Which route applies to you, and the application itself, is a matter for you, your accountant and the Revenue Department's e-Tax Invoice portal. We do not give tax advice.

What we set up on the store side

• An optional "I need a tax invoice" step at checkout that collects the buyer's company name, 13-digit tax ID, head office or branch number and billing address.
• Order data laid out so your accounting software or e-Tax service can issue the document without staff retyping details.
• A connection or export to the invoicing tool your accountant uses, where that tool supports it.
• Clear order numbering and receipts, so every invoice traces back to one order.

If you are not VAT-registered yet, we still build the checkout so these fields can be switched on later without a rebuild.

A typical project with us takes about 15 days. A store with a few dozen products and clean data fits that comfortably. A catalogue of hundreds or thousands of items, messy spreadsheets, or many variants per product will take longer, and we tell you that when we quote rather than halfway through. The steps below follow our general website design process, with the store-specific work added.

Some projects have a twist. If you plan to sell without holding stock, read our notes on dropshipping with Shopify from Thailand first. If you run a restaurant and want online ordering, our page on restaurant website design explains how that differs from a product store.

Before you commit to a platform, these guides answer the questions store owners usually ask about payments, platforms and selling online in Thailand.
