TL;DR

Social commerce is the part of e-commerce where products are found and sold on Facebook, Instagram, TikTok and LINE; live commerce is one of its formats.
TikTok Shop operates in Thailand with in-app ordering, while Facebook and Instagram Shops send buyers to the shop's website, so many Thai shops close sales on a website or in chat.
Measure social sales from paid orders: Seller Center reports, UTM plus pixels for website sales, and source tags logged by admins for every chat order.
Platform risk is real: algorithm changes, account suspensions and fee changes, so keep two sales channels and move buyers into a LINE Official Account you control.

Social commerce is selling where discovery, the buying decision and, in many cases, the order itself happen on social media platforms such as Facebook, Instagram, TikTok and LINE, rather than only on a brand's website. A customer sees a product in their feed, asks about it in chat, and orders from the same place.

This article explains how social commerce differs from e-commerce and live commerce, the main formats, the steps to start selling on social, where ads help, how to measure sales from social, and the risks of depending on a platform. All numbers in the examples are hypothetical and only illustrate the method. None of them are real results from any business.

E-commerce is any form of online selling: a brand's own website, marketplaces and shopping apps. Social commerce is a subset of e-commerce that uses social media as the place to sell. The main difference is where buying intent comes from. On a website or marketplace, customers usually arrive already looking for a product. On social, customers are watching videos or chatting with friends and come across a product along the way. Selling therefore has to start with content that makes people stop scrolling, before it gets to price and checkout.

Live commerce is selling through live streams: the seller shows products, answers questions and closes sales in real time. When the stream runs on a social platform such as Facebook or TikTok, live commerce is one format of social commerce. The difference is that social commerce also covers posts, short videos, in-platform shops and chat selling as well as live streams.

In practice most shops combine several formats, for example short videos to get attention, live streams to clear stock during promotions, and chat to close sales with customers who are still undecided.

Shops on Facebook and Instagram

Meta offers a Shops feature that lets businesses build a product catalog and tag products in posts. Meta has retired in-app checkout for Shops, so tapping a tagged product now sends customers to the shop's website to pay. Shops that prefer to close in chat usually pair the catalog with click-to-message ads instead. Feature availability can change, so check Commerce Manager before planning where to close the sale.

Even without in-app payment, the catalog is still useful, because it feeds catalog ads that automatically show each person products that match their interests.

TikTok Shop

TikTok Shop operates in Thailand. Sellers list products and tag them in videos or live streams, and viewers can view and order without leaving the app. Shops can also work with creators on an affiliate basis: the creator tags the shop's product in their own clip and earns a commission when someone buys. Shop requirements, fees and prohibited-product rules are set by TikTok and can change, so sellers should read the current terms in Seller Center before starting.

Chat selling on LINE and Messenger

In Thailand, chat selling has been common for years. Customers see a product in a post or ad, message the shop to ask about size, colour or shipping, and then pay by PromptPay QR transfer. LINE Official Account suits this model because it has chat, customer tags, auto-replies and broadcasts to existing customers. The limit is that chat selling depends heavily on people. As chat volume grows, you need a response team or tools to manage it, or customers wait too long and drop off.

Live selling

Live streams on Facebook or TikTok suit products people need to see for real, such as clothing, cosmetics, food and collectibles. Viewers can ask questions immediately, and sellers can create urgency with limited quantities or live-only prices. How to set up live selling, from scripts to order handling, is covered on our live commerce service page.

Choose platforms based on your customers, not on trends. Look at where your target customers spend time and whether your product suits short video, still images or chat. Start with one or two platforms.
Prepare complete product information: clear photos, size, colour, material, price, shipping cost and return policy. The same set of information works in the catalog, in posts and in chat replies.
Set up business accounts and catalogs. Use Meta Business Suite for Facebook and Instagram, Seller Center for TikTok Shop, and a LINE Official Account for chat.
Decide where the sale closes: in the app, on the website or in chat. Then make the path as short as possible. Every extra step is a point where customers can drop off.
Set up the back end: stock deduction, packing, shipping and after-sales questions. If you sell on several channels, keep stock in one place so you do not oversell.
Produce content consistently. Social platforms reward consistency, so plan a posting and live schedule your team can actually sustain.
Set up measurement from day one: pixels, UTM parameters and recording the order source in chat, explained in the measurement section below.

Organic content only reaches the people the platform chooses to show it to, which is hard to predict. Ads let a shop decide who sees what, when and how often. In social commerce, ads do four main jobs.

Amplify content that already works. Promote posts or clips with high engagement instead of building new ads from scratch.
Drive people into chat. Meta offers click-to-message ads that take viewers straight into Messenger, Instagram Direct or WhatsApp, which suits shops that close sales in chat.
Show products from the catalog. Catalog ads pull products that match each person's interests, including people who viewed a product but did not buy.
Push people into lives or the shop. TikTok has ad formats tied to TikTok Shop products and to live promotion, which help a stream get viewers early on.

The measurement problem in social commerce is that orders can happen in several places: in the app, on the website and in chat. Each needs a different way of recording. This table summarises how each sales channel is measured.

How to measure sales from social
Sales channel	How sales are recorded	What to watch
In-app shop, such as TikTok Shop	Sales reports in Seller Center, split by video, live and creator	Data stays in the platform; you have to download it and combine it with other channels yourself
Sending customers to buy on the website	UTM parameters on links, plus Meta Pixel and Conversions API or TikTok Pixel, and GA4	Each platform's numbers can double count; use real order data as the baseline
Closing sales in LINE or Messenger chat	Tag customers by source and log each order with its channel in a sheet or back-end system	If admins do not log every order, social sales will look lower than they are
Live selling	Count confirmed order comments and payments per live	Order comments are not payments; count only paid orders

Numbers to track

Paid sales by channel, not orders placed or comments
Chat close rate: orders divided by new chats
Ad cost per order, compared with gross profit per order
Repeat purchase rate for customers from each platform
Return or cancellation rate, which tends to be higher for quick-decision purchases

A hypothetical calculation

Suppose a clothing shop spends 15,000 baht on click-to-message ads in a month and gets 600 new chats. Admins close 90 orders, so the chat close rate is 15% and the ad cost per order is about 167 baht. If the average order is 890 baht and gross profit per order is 350 baht, the campaign is profitable. But if admins reply so slowly that the close rate drops to 8%, the cost per order rises to about 313 baht. The example shows that in chat selling, response speed affects profit about as much as the ads do.

The risks of depending on a platform

Social commerce lets you start selling fast, but you are building a business on someone else's land. These are the risks to understand before you invest effort.

Algorithms change constantly. The organic reach you used to get can drop without notice.
Accounts can be suspended. An unintended policy breach, such as an exaggerated product claim, or being reported, can get an account or shop closed temporarily.
Fees and terms can change. Platforms can adjust fees, commissions and payment terms, so recalculate your margins every time they do.
You do not fully own the customer data. Especially with in-app sales, you may not get a direct way to contact customers again.
Price competition. When many shops sell the same product on one platform, customers can compare prices in seconds.

How to reduce the risk

A workable approach is to spread sales across at least two channels and gradually move customers into channels the shop controls. For example, invite customers to add the shop's LINE Official Account with a perk for their next purchase, or collect phone numbers and emails with consent under Thailand's PDPA. Always keep backups of product data, images and sales reports outside the platform, so that if an account has problems the shop can open a new channel quickly.

The Thai market has specific traits worth planning for. First, buying through chat is normal, and many customers expect to message before transferring money, so shops that reply fast with complete information have an edge. Second, PromptPay QR makes payment in chat easy, but shops need a step to verify transfer slips and guard against fake ones. Third, cash on delivery is still an option some customers expect, which adds the risk of refused deliveries, so shops should track that rate by channel. Finally, advertising for some product types, such as supplements, cosmetics and health products, is governed by both Thai law and platform policies on claims, so check ad copy before every launch.

Social commerce is selling on social media: customers see products, ask questions and order on platforms such as Facebook, Instagram, TikTok or LINE, without having to start on the shop's website.

E-commerce is all online selling, while social commerce is the part of e-commerce that uses social media as the place where products are discovered and sold. Customers usually come across products while watching content rather than searching for them.

Yes, when the stream runs on a social platform such as Facebook or TikTok, live commerce is a format of social commerce that sells through real-time live video.

Start with the platform your target customers use most and that suits your product: products that need demonstrating fit short video or live streams, while products customers ask a lot about before buying fit chat selling on LINE.

No, you should not depend on one channel, because platform algorithms, policies and fees can change. Keep at least two sales channels and move customers into channels you control, such as a LINE Official Account or a membership base.

Social commerce that works needs content that stops people scrolling, ads that move them to the point of sale, and measurement based on paid orders. The Relevant Audience team can plan and manage social media advertising connected to your shop's sales channels.
