Shopee, Lazada and TikTok Shop have all raised their sales transaction fees and introduced additional service charges, leading to higher costs for merchants.
This trend signals the platforms’ drive to increase profitability, while also reflecting their dominant market power by placing a greater financial burden on sellers.
Moreover, TikTok Shop has for the first time expanded its “Pay later” financial service to encompass a broader range of users after piloting a trial among a small number of users late last year.
TikTok Shop’s rivals, Shopee and Lazada, have long been operating this kind of service.
Industry analysts warn that these platforms are no longer just marketplaces — they now control payment systems, logistics, advertising, financial services, and insurance, all powered by behavioural data from over 30 million users.
On Sept 15 this year, Shopee increased its sales transaction fee by another 0.6-1 percentage point, depending on the category, along with a new “Platform Infrastructure Fee” of 1 baht per order.
On Sept 28, Lazada raised its seller fees by 2 percentage points for both regular sellers and LazMall merchants.
Effective as of Oct 1 this year, TikTok Shop said it would be adjusting its platform fees as part of a broader investment strategy “to maintain a safe, sustainable, and inclusive ecosystem”. The new fees are a Commerce Growth Fee of 5.35% for electronics and 6.42% for other categories, capped at a maximum of 199 baht per unit (including VAT), and an Infrastructure Fee of 1.07 baht, which will be waived for sellers with fewer than 100 monthly orders.
In a statement, TikTok Shop said: “We continue to be committed to enabling businesses of all sizes. In 2025 alone, in Thailand, TikTok Shop is investing over US$2 million [64.7 million baht] to promote Thai companies. We recently launched a TikTok Shop E-commerce Curriculum for entrepreneurs in partnership with the Ministry of Digital Economy and Society.”
Pawoot Pongvitayapanu, honorary president of the Thai e-Commerce Association, said Thailand’s digital economy faces growing concerns over the dominance of e-commerce platforms, which are rapidly evolving into commercial infrastructure giants.
By leveraging customer data — such as purchase habits, payment patterns, and delivery preferences — platforms are building powerful engines for personalised promotions, upselling, and cross-industry expansion.
This poses significant risks to five key sectors.
Regarding banking and finance, the platforms compete by offering lending and instalments such as “buy now, pay later” services during the payment process, using real-time payment data to assess creditworthiness, which is often more accurate than traditional credit bureaus.
Their proprietary e-wallets also divert transaction fees away from banks, while those financial institutions lose access to stock-keeping unit-level data, weakening their ability to offer competitive pre-approved loans.
Retailers and brands are increasingly dependent on platforms for visibility, often paying for promotion in a “pay-to-play” model.
Platforms have also launched their own private-label products based on top-selling items, undercutting suppliers. Loyalty tools such as coupons and points keep customers within the platform ecosystem.
For logistics and warehousing, the e-commerce platforms are building their own delivery networks and fulfilment centres, setting service levels and pricing.
With access to end-to-end route and cost data, they can optimise operations beyond the reach of traditional logistics providers.
When it comes to the media and advertising sector, their budgets are shifting towards platform ecosystems, where closed-loop attribution links ads directly to sales.
The platforms’ first-party data enables precise retargeting and personalised promotions, reducing reliance on traditional media.
The platforms offer insurance services, covering parcels and accidents.
Their future expansion could reach travel, health, education, telecom, and utilities — any service that can be embedded at the checkout and supported by user data.
Mr Pawoot explained how platforms tighten their grip by use of a data flywheel, as more sales generate more data, enabling better recommendations and higher conversion rates.
They can have a cross-sell engine by using points and coupons that link products with financial, insurance, and logistics services.
Mr Pawoot suggests businesses collect first-party data via customer relationship management and owned channels (such as the web, apps, and Line) while using marketplaces to acquire new customers, then convert them into brand members.
The businesses should partner with banks and insurtechs to embed financial and insurance services.
They should collaborate on logistics to negotiate better service levels and pricing. Mr Pawoot urged the government to step in and ensure fair competition. Without intervention, monopolistic platforms could expand unchecked, threatening the survival of traditional businesses across multiple sectors.
“Marketplace platforms are no longer just selling products — they’re becoming the backbone of Thailand’s commercial infrastructure,” Mr Pawoot said. “If businesses don’t act now to reclaim data and embed their own services, they risk losing margins, bargaining power, and loyal customers.”
