About E-Commerce China Agency

Why Independence Matters

Being independent matters more than most brands realize before they enter China. Platform-affiliated agencies tend to push whatever ad product their parent company is selling that quarter, whether or not it fits the brand. Because EAC is not owned by Alibaba, JD, or ByteDance, our recommendations are based on what actually moves sales for a specific brand and category, even when that means spending less on advertising and more on fixing the store, the pricing, or the product listing first.

Our Leadership

Harry Huang

Founder

Harry Huang founded E-Commerce China Agency and leads it today. Before starting EAC, Harry spent several years at Volkswagen in China, where he worked on digital and ecommerce projects for one of the largest automotive groups operating in the country. That corporate background gave him a rare mix: the discipline and reporting standards of a multinational, combined with a deep, practical understanding of how Chinese platforms actually convert traffic into sales.

Harry has 8 years of ecommerce experience in China, across Tmall, JD.com, and Douyin. He has personally overseen store strategy and performance for some of EAC’s largest accounts, including Nestle, Vitabiotics, and Ferrero. His approach is straightforward: set a clear ROI target before a campaign starts, then build the store, content, and media plan backward from that number. Brands that work with Harry usually say the same thing, that he tells them what will not work as clearly as what will.

Matt Sun

Chief Ecommerce Officer

Matt Sun joined EAC after 10 years managing Tmall stores and ecommerce operations, including time spent inside Alibaba itself. That platform-side experience means Matt understands Tmall’s ranking logic, promotion calendar, and category rules from the inside, not just from the outside looking in as most agencies do.

As Chief Ecommerce Officer, Matt owns ecommerce delivery across EAC’s client portfolio: store health, product listings, promotion planning, and the operational side of livestream and campaign events. He has led Tmall management and ecommerce operations for brands like ThaiBev, Yili Group, Lyfen, and Beats. Matt’s team is the one that makes sure a campaign a client approves in a strategy deck actually runs correctly on the platform, on time, with the right pricing and stock in place.

Our Team in Kunshan

EAC operates with a team of 50 people based in Kunshan, near Shanghai. The team is organized by function: Tmall and JD store managers, Douyin content and livestream specialists, paid media buyers, customer service, and graphic designers who produce listing pages and campaign creative in-house. Having the full team under one roof in Kunshan means store managers, content producers, and media buyers sit next to each other, which cuts down the back and forth that usually slows down ecommerce execution when an agency outsources pieces of the work to different vendors.

Most of our team members have worked exclusively on Chinese platforms for their entire career. They are not generalist marketers who added Tmall to their resume, they are ecommerce specialists who have never worked outside the Chinese platform ecosystem. That specialization is a big part of why our clients keep renewing year over year instead of testing three agencies before finding one that delivers.

The Kunshan location also keeps our cost structure lean compared to agencies based in downtown Shanghai or Beijing, without any loss of talent quality. Kunshan sits close enough to Shanghai that our team can meet clients, attend platform events, and visit warehousing or manufacturing partners easily, while avoiding the overhead that gets baked into agency fees when an office sits in a central business district. That saving goes back into the account, either as more content production, more testing budget, or a lower monthly retainer.

Results We Have Delivered

ROI 1:10

Nescafe

Our best result to date. Store management and campaign work delivered a 1 to 10 ROI. Coffee is one of the fastest growing categories on Chinese platforms right now, and an established brand like Nescafe benefited from a store and content refresh that matched where Chinese coffee consumers actually spend their time, which is Tmall for repeat purchase and Douyin for discovery.

15M USD cumulative

Vitabiotics

One of our longest-running health supplement accounts. Our team built and grew the brand’s Tmall presence to 15 million USD in cumulative sales, supported by WeChat mini-program integration and ongoing content and CRM work. Health supplements require heavy trust-building in China, so a large part of the work went into product education content and third-party validation, not just paid traffic.

12M RMB · ROI 1:4

Lyfen

For Lyfen, a snack and food brand, EAC drove 12 million RMB in sales with a 1 to 4 ROI. Store management, promotion calendar planning around key shopping festivals, and consistent content refresh were the main levers behind the result. Snack categories move fast in China, and staying visible during festival periods like 618 and Double 11 made most of the difference.

3M RMB · ROI 1:3

ThaiBev

Our team managed Tmall store operations and campaign execution for ThaiBev, reaching 3 million RMB in yearly sales with a 1 to 3 ROI on ad spend. The work combined store optimization, seasonal campaign planning, and paid media on Tmall, focused on building repeat purchase behavior in a category where brand loyalty in China is still being formed.

ROI 1:3

Beats

EAC ran an ecommerce marketing campaign for Beats, achieving a 1 to 3 ROI. Consumer electronics and audio products sell heavily on content and social proof in China, so the campaign leaned on Douyin content and KOL placements alongside Tmall store promotion to drive both awareness and direct sales in the same push.

ROI 1:3 at launch

Yili Group, New Water Brand

When Yili Group launched a new bottled water brand, EAC supported the ecommerce side of the launch, reaching a 1 to 3 ROI during the initial go-to-market phase. For a new brand entering an already crowded category, that number reflects the cost of building visibility and trial before repeat purchase and organic search traffic start doing more of the work.

Why Brands Choose EAC

Most ecommerce players want to increase their sales in China and are searching for a competitive agency that uses its budget efficiently, has professional staff, and stays dedicated to helping partners grow year over year. Here is why working with an independent ecommerce agency like EAC tends to outperform going direct or working with a platform-affiliated vendor:

• Market understandingOur team has a deep, current understanding of local market dynamics, consumer behavior, and platform rules. That knowledge is what lets us position products correctly and adapt marketing strategy to Chinese consumers instead of translating a Western campaign and hoping it works.
• Platform expertiseChina’s ecommerce ecosystem is dominated by Tmall, Taobao, JD.com, and Douyin. Each platform has its own rules, user base, and optimization logic. Our team specializes in each of these platforms individually rather than treating them as one generic China channel.
• Digital marketing executionDigital marketing in China runs on platforms that most Western marketers have never used as a buyer. Our content, KOL, and media buying teams work inside these platforms daily, which is the only way to keep up with how fast the rules and best practices change.
• Operational supportLogistics and customer service in China are complex given the country’s size and the pace consumers expect. Our Kunshan team handles listings, promotions, customer inquiries, and coordination with warehousing partners, so our clients are not managing that complexity from abroad.
