Below, through this article and the case of Shein, we will gain a concrete, practical understanding. PDA supply chain.

 

 

The secret weapon behind Shein’s rise: PDA Supply chain

 

In China, people may be unfamiliar with “ Shein ” I’m not very familiar with it, but overseas, this company is extremely popular.

A leading application data analysis software from abroad App Annie and Sensor Tower Data show that as of 2021 year 11 Month, Shein ( SheIn ) is global 60 Number one in a country or region iOS shopping app, and in 15 Orders from countries and regions ( Android ) It ranked first in app downloads and even briefly surpassed the app of U.S. e-commerce giant Amazon, becoming the top app in the United States. iOS and Google Play The shopping app with the highest number of downloads on the platform.

As of 2021 year 11 Month, Shein is in Instagram 、 TikTok And Facebook ( Facebook ) The number of followers on social media has already reached nearly 3 Hundreds of millions of people, company 2020 Annual total revenue 90 Several hundred million dollars, nearly doubling from the previous year, consecutively… 8 Annual revenue has achieved 100% Growth, with over annual active users 3000 Ten thousand people, took on 1.2 One hundred million registered users.

The predecessor of Shein was founded in 2008 In [year], the company was founded in Nanjing, China, by Xu Yangtian, who began his career in search engine optimization. Early on, Xu recognized the emerging opportunities in cross-border e‑commerce and launched a cross‑border business selling wedding dresses—then the second-largest category in the sector after consumer electronics. Leveraging this strategy, Xu Yangtian secured… SheInside.com its domain name and established its own independent website.

2012 In that year, Xu Yangtian officially abandoned the wedding‑dress business and used… SheInside.com The domain name was fully pivoted to cross-border women’s fashion, keeping pace with fast‑fashion trends, and thus Shein’s story began.

2015 Year, SheInside It has been rebranded as SHEIN, and its product lineup is expanding to cover all categories, with a commitment to building a cross-border platform. B2C A fast-fashion apparel brand. Currently, Shein operates through its own independent websites, dedicated mobile apps, and online platforms such as Amazon, serving markets across the United States, Europe, India, the Middle East, Southeast Asia, and beyond. 200 Products are sold in multiple countries and regions, with peak daily shipment volumes exceeding 300 Ten thousand items.

To a certain extent, Shein outperforms the leading international fast-fashion brands. —— In 2020 When the COVID-19 pandemic struck, including leading international fast-fashion brands Zara While numerous global fast-fashion brick-and-mortar stores have suffered a severe blow, Shein has instead achieved growth against the trend by focusing exclusively on online channels. 2020 In the year, Shein’s revenue growth was 253.4% , and Zara Revenue declined during the same period. 27.9% 。

“ Affordable and a wide variety of styles ” This is the impression many consumers have of SHEIN. Its product lineup is divided into four categories: standard-size women’s wear, plus-size women’s wear, children’s wear, and men’s wear. The price ranges listed on the official website are as follows: 2 ~ 77 U.S. dollar, 4 ~ 75 U.S. dollar, 2 ~ 35 U.S. dollar, 5 ~ 71 U.S. dollars, with the prices of most products ranging from 20 Below one US dollar.

A college student from Georgia, USA, posted their Shein shopping list on Facebook, and the order shows that they purchased 16 items, total 108 US dollars, the cheapest trinkets cost only 1.38 The U.S. dollar, and also 6 The Lady of the Dollar T shirt, 12 A dress made of dollars ……

 

 

In addition, SHEIN’s official website also displays the number of new arrivals for the past week. 2020 year 5 month 24 Day, 25 Day, 26 The number of new arrivals across all categories for Rihyin women’s apparel has reached 3 839 style, 3 936 style, 4 067 item. It is reported that, 2019 Yinxin’s annual new-product launch volume reaches 15 Tens of thousands of items, with new arrivals added on average each month. 1 Over ten thousand models—this means it can catch up in just one to two months. Zara The total number of new items launched throughout the year.

In addition to its low prices and wide variety of styles, SHEIN’s marketing strategy has also played a key role in driving its explosive sales. As early as… 2011 In that year, Shein began leveraging social media influencers to promote its products and drive traffic to its platform. However, Shein’s ability to respond swiftly ultimately stems from the robust supply chain that underpins it.

 

Supporting sales revenue PDA Supply chain

2014 year's SheIn It has already gained some recognition within the industry, and its primary business model is as follows: the company sources merchandise from Guangzhou’s Shisanhang Clothing Wholesale Market, modifies the wholesalers’ product images, and uploads them to its website. Once a customer places an order, a dedicated representative handles procurement at the wholesale market and arranges shipment.

 

As the company’s overseas expansion accelerates, as of 2014 By the end of the year, its monthly sales had already reached 3000 Ten thousand yuan—supply-chain issues are beginning to surface.

According to the recollection of a company executive at the time, someone directly laid out the company’s predicament to its founder, Xu Yangtian: “ The company’s key challenge is an overabundance of product SKUs, which makes it impossible to stock every item. Instead, we must source products from the market based on customer orders, leading to lengthy lead times and a poor user experience. While new user acquisition is growing rapidly, retention remains low. At the same time, our marketing expenses continue to rise, creating a self‑reinforcing cycle that is far from sustainable. ”

After much deliberation, Xu Yangtian decided to integrate the upstream and downstream links to build a fully integrated supply chain.

 

Starting from consumer demand

Drive the entire supply chain

 

Accurately understanding market trends and consumer needs is the first step for fast-fashion brands to capture market share.

The traditional fashion industry develops clothing on a seasonal basis, and it takes… from design to production to being placed on store shelves. 3 months. As the pioneer of fast fashion, Zara It’s not about guessing—it’s about following the trends.

Zara Designers and buyers often identify emerging trends from the latest collections unveiled at major fashion shows, then reinterpret and combine these elements into their own designs. Its global… 7000 Many stores also collect customer feedback daily and transmit this information to the company’s headquarters data center for reference by the design team.

The practices of Shein and Zara Similar, but with differences.

Born in the internet era, Shein’s greatest strength lies in its adept use of digital technologies, which bring it closer to consumers and foster richer, more meaningful engagement. Across multiple social media platforms, Shein leverages interactive content, influencer‑driven livestreams, short videos, and other formats to connect with its audience, amassing hundreds of millions of followers.

Meanwhile, SHEIN leverages digital tools to collect data and analyze consumer demand. At an event, the former general manager of SHEIN Mobile unveiled the company’s tracking system: it aggregates products from a wide range of online apparel retailers, systematically summarizing current trends in color palettes, price fluctuations, and pattern motifs. Designers and buyers then synthesize these insights—gathered across multiple channels—to craft new collections.

Shein is also on Google. (Google) of customers. It leverages a search trend detector (Google Trends Finder) Discover the search volume and upward trends for trending keywords across products from different countries, such as which colors, fabrics, and styles are likely to be popular.

For example, Shein accurately predicted 2018 In the summer, lace styles popular in the U.S. and all-cotton fabrics favored in India were in vogue. In addition, SHEIN has built its own IT team and developed a proprietary algorithmic framework that can predict inventory levels by analyzing users’ likes, shares, engagement behaviors, as well as their purchasing patterns, decision-making processes, and time spent in the shopping cart. (SKU) Future demand.

 

“ Small orders, quick response ” Agile supply chain

 

Shein on 2015 A branch was established in Guangzhou this year. Guangzhou is home to China’s most renowned textile, apparel, and fashion industry cluster, as well as a relatively well-developed infrastructure for cross-border logistics and other related services.

Shein has built its own design team, initially setting up temporary workshops for garment pattern-making. By the time… 2016 In that year, Shein already had a… 800 A team of people quickly designs garments, creates prototypes, and then sends them to the factory for production.

 

 

In addition to its in-house team, SHEIN also enhances its design capabilities by engaging external designers, enabling it to more flexibly adjust the volume of designs. For example, it has… 2021 Launched a designer incubator this year. “SHEIN X” , aiming to provide independent fashion designers and illustrators with opportunities to collaborate with SHEIN and expand their brands to a wider audience.

SHEIN X Designers only need to focus on creation, while leaving manufacturing, marketing, and sales to Shein. Designers can share in the profits and retain ownership of their designs. Since… 2021 year 4 Starting this month, SHEIN will launch new designer‑collaboration apparel every month.

In addition, to accelerate the process from design to sampling, SHEIN is further leveraging both internal and external human resources by… 3D The application of digital tools—such as virtual design, digital pattern‑making, and fabric libraries—helps accelerate the process from design to sample production. These capabilities form a key foundation for Shein’s ability to launch hundreds or even thousands of new items every day.

Another key foundation for Shein’s rapid product launches lies in its manufacturing process. Since 2014 Starting in [year], Shein began vigorously supporting its own contract manufacturers and grassroots supplier network, in order to establish what is critical to fast-fashion brands. “ Small orders, quick response ” Ability.

Shein's “ Small orders, quick response ” , allowing a single clothing style to have only 100 One order is enough to start production. This means that, using the same… 3 000 One piece of clothing to test market response; competitors may test at most… 6 a single style, whereas SHEIN can test up to 30 a style, so its appearance “ Bestseller ” The probability will be higher.

 

Moreover 100 Even small batch sizes mean that Shein can afford to experiment with different fabrics and color combinations at a lower cost of failure. As a result, Shein’s apparel feels more vibrant and youthful, featuring bold hues, an eclectic mix of materials and prints, and few classic black‑white‑gray staples.

 

Collaborate with suppliers for mutual benefit and win-win outcomes.

 

Shein Company “ Small orders, quick response ” Building capabilities is far from smooth sailing.

 

2014 In that year, almost no factories were willing to take on even a single product from Shein. 100 Such a small order. At the time, one supplier stated: “ The machine’s one-time startup alone exceeds this cost; if we proceed, we’ll be losing money. ” In this situation, a former mid-level manager at Shein believes that “ At the outset, the most important thing Shein did was to be willing to wait for and support its factories. ”。

 

 

For example, SHEIN handles the pattern-making and sample production itself, with costs ranging from a few hundred yuan to over a thousand yuan. By contrast, if a factory were to handle this task on its own, one… 100 Even a single order might not generate that much profit. SHEIN will also place slightly larger orders, taking on the inventory pressure itself. ——“ Suppose I think you’re doing… 80 It’ll lose money, I’m out. 100 For this order, I am willing to assume the inventory myself. ”

 

In terms of payments, Shein never delays settling accounts with its suppliers and strives to expedite the payment process, typically… 30 ~ 45 Payment can be settled within one day. “ If the payment date falls on a weekend, SHEIN will process the payment on Friday instead of postponing it to Monday. ” A supplier stated in an interview.

 

In addition, Shein sometimes even lends money to factories to help them purchase premises and upgrade their equipment, thereby supporting like-minded suppliers in growing together. The head of one factory said: “ Right now, everyone is scrambling to do business with Shein. "2015" In that year, Shein relocated its Guangzhou supply-chain hub to Panyu, and nearly all the factories that had previously partnered with Shein moved along with it.

 

Through this model of mutual support, SHEIN has so far developed more than 300 The home’s ready-to-wear supplier and 100 Home textile and accessory supplier, Hundreds of factories clustered around it, forming an industrial ecosystem—yet not a single one is owned by SHEIN.

 

In return, SHEIN places higher demands on suppliers’ service and product‑category quality. Its supplier performance evaluation focuses on four key metrics: on-time fulfillment rate for rush orders, on-time preparation and shipment rate, defect rate, and new‑product launch success rate. One factory that has partnered with SHEIN noted that the bar for collaboration is now very high. “ The delivery date for the repeat order is 8 days (whereas traditional factories typically take more than half a month); the number of loose threads on a single garment must be fewer than 3 Root, and not exceeding 3 Centimeters long; dimensional tolerance is within 2 Within centimeters ”。

 

A digital supply chain serves as the underlying backbone.

 

Digitalization is the backbone of SHEIN. “ Small orders, quick response ” Another key factor is that SHEIN has developed a supply-chain information system that is difficult for imitators to replicate, with dedicated systems tailored to each stage of the supply chain.

 

Take the production department as an example: all of Shein’s contract manufacturers and suppliers can access the production management system ( Manufacturing Execution System ， MES ), enabling real-time, visual tracking of every stage in each order, thereby optimizing scheduling and boosting production efficiency.

 

 

However, this supply-chain information system did not come into being overnight. According to a former middle-level manager, initially, Shein’s entire back-end supply chain relied on a single information system.

 

As the number of partnered suppliers continued to grow, SHEIN began implementing more targeted, diversified information systems and instituted an internal process of performance‑based selection, ultimately giving rise to the supply chain information system it operates today.

 

Currently, SHEIN requires all partner factories to use its supply-chain information system. Hundreds of factories that had never been digitized have now been integrated into a single platform, enabling end-to-end process visibility and facilitating optimization through data accumulation and analysis.

 

Currently, Shein’s comprehensive supply chain system, logistics network, and enterprise resource planning ( Enterprise Resource Planning ， ERP ) Both the system and the entire sales forecasting framework rely on a comprehensive set of data‑driven algorithms to achieve optimization and integrated coordination.

 

With these capabilities, Shein’s suppliers deliver far faster than the industry standard. Earlier, Shein required its contract manufacturers to complete the process—from order placement to delivery of goods to the Foshan satellite warehouse—within a maximum timeframe of 15 Heaven. Arrive 2020 In that year, this cycle had already been shortened to 11 Heavens, seven or eight days is the usual pace.

 

According to a top supplier of Shein, it takes only… from receiving an order and sourcing the fabric to delivering the finished garments to their warehouse. 5 Heaven: Fabric Production 1 Heaven, cutting, sewing, and finishing 3 Heaven, secondary processes (embroidery and printing) 1 Heaven. When faced with surge orders for a hit product, SHEIN’s suppliers can even deliver faster. By contrast, across the entire fast-fashion industry, the average lead time for suppliers—including those of traditional, world‑leading brands—is typically… 15 ~ 20 Heaven.

 

Support for warehousing and logistics resources

 

Shein’s supply chain center has allocated its largest workforce to the warehousing and logistics department, The warehousing department alone has more than … worldwide. 4000 Employees—this nearly accounts for the entire supply chain center. 80% Human resources.

 

Shein can now ship to more than 220 It delivers to markets in multiple countries and regions, with dedicated support websites in the United States, Spain, France, Russia, Germany, Italy, Australia, and the Middle East. SHEIN fulfills orders by shipping products from warehouses located at these global sites directly to consumers in each region.

 

According to a study on SHEIN’s global warehouse network, the company currently operates three types of warehouses worldwide: domestic fulfillment centers, overseas transit hubs, and overseas operational warehouses.

 

Its domestic central warehouse is located in Foshan, Guangdong, with several satellite warehouses nearby. Globally 95% The product is shipped from the domestic central warehouse. As of 2019 In the year, the Foshan central warehouse held approximately 3 000 Ten thousand items, approximately is 40 Ten thousand～ 50 ten thousand SKU 。

 

Meanwhile, Shein operates multiple overseas transit warehouses worldwide, located in countries and regions such as Saudi Arabia, Dubai, Italy, Australia, Vietnam, and Indonesia. These overseas transit warehouses are responsible only for receiving returns from consumers and do not handle shipments. The inventory at these overseas transit warehouses is approximately… 1 000 Ten thousand items, approximately is 15 ten thousand SKU 。

 

In addition, Shein operates fulfillment warehouses in Hong Kong, Delhi, the northeastern United States, and the western United States, which are responsible for delivering to their respective service areas. These overseas fulfillment centers generally handle approximately… 5% of global shipments.

 

Over the past few years, despite Shein’s substantial investments in overseas warehousing to accelerate cross-border logistics, it still lags behind the world’s leading brands in this area.

 

According to the “China Cross-Border E-Commerce Development Report” jointly released by Google and Deloitte, Zara Delivery times in the United States are typically 3 ~ 5 Heaven, but at present, Shein’s delivery time in the U.S. market is at least one week. In the U.S. market, Shein primarily offers standard shipping ( Standard Shipping ) and express delivery ( Express Shipping ) Two delivery options.

 

The Shein app indicates that after placing an order, selecting standard delivery requires 16 ~ 17 The item can be delivered, and choosing express delivery also requires… 8 ~ 9 Heaven. Of course, this is also due to the outbreak of the COVID‑19 pandemic, which has led to longer customs clearance times for international freight. 2 ~ 4 Heavens, but overall, the delivery time for Shein’s products isn’t exactly short.

 

At present, SHEIN has largely completed the construction of its backend supply-chain ecosystem. Its primary business process unfolds as follows: starting with consumer demand, it gathers relevant insights through buyers, brick-and-mortar stores, and web-scraping technologies, then relays this information to the product planning and design teams for initial conceptualization.

 

Then, the front end attracts consumers through multi-channel marketing and ad placements, while the back end collaborates with upstream suppliers in the supply chain, by… “ Small orders, quick response ” Complete the order. Finally, warehousing and delivery handle the last-mile delivery to the consumer. The entire process relies on its digital supply-chain capabilities.
