E-commerce Websites for Businesses That Actually Sell
Last updated 16 September 2026
TumWebSME builds custom-coded online stores for businesses that already sell — social-first brands, shops with a physical location that want to reach beyond it, and businesses whose selling model does not fit a standard store template. Because we write the code, the product structure and the checkout follow how you actually sell.
To be clear: your own store does not replace the marketplaces or the page you sell on today, and we do not promise a sales increase. What it gives you is a channel where you set the rules, keep the customer data, and pay no per-order commission. Our team is in Bangkok and runs projects anywhere in Thailand online. Pricing is the same package table shown below.
@tumwebsmeYou already sell on marketplaces — why your own store too?
Marketplaces do what a new website cannot do on day one: put your product in front of people who have never heard of your brand. Keep selling there. What they do not give you is the customer relationship, the data, or the margin the commission takes — and when the platform changes its rules or its fees, you simply absorb it. Your own store is where repeat buyers, followers and people searching your brand by name can buy directly.
Stores fail on the boring parts, not the design
The stores that struggle rarely fail on looks. They fail on product data structured badly at the start, stock that stops matching reality, a shipping cost that surprises people at checkout, and a payment method the customer does not use. We settle those questions before any code is written.
- Products, variants (colour, size, pack) and stock modelled separately and correctly
- Shipping charged the way you actually charge it — by weight, by zone, or free over a threshold
- Payment methods your customers really use, connected to the provider account you hold
- Order status and tracking pages, so buyers can check without messaging you
Speed and stability at checkout are revenue questions
A slow About page costs nothing. A slow product page and a checkout that stalls cost sales, because someone about to pay reads a frozen screen as a risk to their money. We compress product images, load only what a page needs, and test the full purchase flow on real phones before handover. Traffic also arrives in bursts on campaign days — TCG Thailand, a trading-card auction marketplace, was built for that pattern from the start. Selling beyond your own province or country adds another layer: language, shipping cost shown per destination, and payment methods that differ by country.
What building a store actually involves
We start with the catalogue: your real product list, agreed into categories, products and variants. It is the one thing that is expensive to change later. Next come the owner decisions — how you ship, how you charge for it, how you take payment — explained with their trade-offs before anything is designed. You approve the design, then test a staging link and place a real order on your own phone.
The last step is the admin handover, and it decides whether the store survives. You add a product, change a price and mark something out of stock yourself before launch, because a catalogue nobody maintains stops matching the real shelf within months.

Frequently asked questions
Should I close my marketplace shops if I get my own store?
No, and we do not recommend it. Marketplaces still bring discovery from people who do not know your brand. Your own store serves the customers who already do. Most sellers run both.
Do I have to load the products myself?
We load an agreed first set at launch. After that you maintain the catalogue through the admin panel — adding products, changing prices, marking items out of stock — with training before go-live.
Which payment methods can you support?
We connect the payment provider you hold an account with, and can keep bank transfer with proof of payment if your customers still use it. The provider contract stays yours; we integrate and test it.
Can I sell to customers outside Thailand?
Yes, with three decisions made up front: which languages, how shipping cost and delivery time are shown per destination, and which payment methods appear in each country. Included languages per package are in the price table.
How long does an online store take?
Longer than a standard business website, because the catalogue has to be structured and the purchase flow tested end to end. The estimate depends on product count and variant complexity, and custom systems start with a written scope (SRS).
