#775 2003 · Shuangtong Plastics (双童吸管), Yiwu · Manufacturing / distribution strategy
When Walmart and Dollar Tree became Shuangtong's biggest straw customers, founder Lou Zhongping fired them, calculating that one giant buyer's price leverage was worth less than ten thousand small ones who couldn't dictate terms.
the problem
a manufacturer's largest, most prestigious customers use their sheer purchase volume to squeeze the supplier's margin toward nothing, and the more the supplier grows to serve them the thinner its profit becomes
background
Shuangtong, a plastic-straw manufacturer founded in Yiwu, Zhejiang, grew through the late 1990s and early 2000s by winning orders from major Western retailers, including Walmart and Dollar Tree — exactly the kind of marquee accounts most small Chinese exporters chased. On paper the factory was thriving: production capacity kept expanding to meet the volume these retailers demanded. In practice, margins told a different story. A straw sold for a fraction of a cent, and as foreign big-box buyers came to occupy nearly all of Shuangtong's production capacity, they used that concentration to keep pushing the price down — the factory's own bargaining position weakened in direct proportion to how dependent it had become on a handful of giant customers.
By the early 2000s Shuangtong was larger by volume than it had ever been and less profitable than it had ever been, caught in a trap common to manufacturers who scale by serving retail giants: the customer relationship that looks most like success is also the one doing the most damage to the bottom line, and growing the relationship further only tightens the squeeze.
what everyone would do
Keep chasing and expanding the relationship with major retail accounts like Walmart and Dollar Tree -- the standard growth strategy for a small manufacturer, since marquee big-box customers look like validation and scale, the exact accounts most exporters actively pursue.
what they saw
Lou Zhongping saw that Shuangtong's biggest customers weren't actually its most valuable ones -- their sheer purchase volume was precisely what let them dictate price down toward the factory's cost, so the more the company grew to serve them, the thinner its margin became. The insight wasn't that big customers were bad, it was that concentration itself was the vulnerability: ten small customers who each lacked leverage individually were worth more in aggregate than one large customer who could set terms unilaterally.
the move
In 2003, Lou Zhongping made the decision to abandon Shuangtong's largest customers, Walmart and Dollar Tree among them, and redirect the company's commercial focus toward the domestic Chinese market and a large number of small buyers instead, reasoning that 'if one large customer equals ten small ones, why not find ten small customers instead — a large customer dictates terms, small customers we can negotiate with.' Shuangtong expanded its sales team and became an early adopter of Alibaba's business-to-business trust-certification program to reach thousands of small, independent buyers who each ordered too little individually to ever gain Walmart's pricing leverage.
why it works
By deliberately walking away from Walmart and Dollar Tree and redirecting sales toward thousands of small, independent buyers through Alibaba's B2B platform, Shuangtong traded a handful of relationships with outsized pricing power for a large base of buyers none of whom individually mattered enough to demand the same discounts. Because no single customer in the new base could threaten to walk with a meaningful share of revenue, Shuangtong regained genuine negotiating leverage on price, which is why margins recovered from near-zero to roughly 20% even as the customer count grew into the tens of thousands.
the payoff
Shuangtong's customer base grew to more than 20,000 documented buyers, with sales split roughly 50-50 between domestic and export markets instead of concentrated in a handful of foreign retail accounts. Net margins recovered to roughly 20%, a dramatic rebound from the near-zero margins the big-box relationships had left the company with. The diversified customer base also gave Shuangtong resilience the concentrated model never could: when the 2008 global financial crisis hit export-dependent Chinese manufacturers hard, Shuangtong weathered it while competitors still tied to a small number of large foreign buyers struggled.
where it breaks
This strategy requires having (or being able to build) the sales infrastructure to acquire and service thousands of small accounts instead of a handful of large ones, which is operationally far more demanding -- more relationships to manage, more individual transactions, more customer-service overhead per dollar of revenue. It also depends on a large enough pool of small buyers actually existing for the product in question; a niche or highly specialized product with no viable small-buyer market has no alternative customer base to diversify into, leaving concentration in a few large buyers as the only real option regardless of the pricing pressure it creates.
what came after
Lou Zhongping's 'small customer principle' (小客户原则) became one of the standard-cited cases in Chinese business schools, including MBA programs at Tsinghua and Zhejiang University, for the specific counterintuitive move of deliberately firing a company's largest, most prestigious customers rather than merely diversifying around them — treating customer concentration itself as the risk to eliminate, not just the revenue to protect.
