The small-batch, on-demand manufacturing model has been the bread and butter for Shein’s rapid growth, with the e-commerce retailer reportedly making more than $30 billion in revenue in 2023.
Partnering with roughly 5,400 third-party contract manufacturers in China, Shein can churn out tens of thousands of new styles daily. The company places orders to suppliers to be delivered in days, shipping roughly 5,000 metric tons of goods via air freight per day, according to data from Cargo Facts Consulting.
The fashion firm also leverages real-time data to quickly analyze demand and replenishes orders as needed, while also allowing it to quickly boost production of popular items and drop products that do not sell as expected. Using this data, Shein can reduce storage costs and limit inventory waste—further allowing the company to maintain low prices in the form of $10 dresses and $5 shirts.
