Fulfillment for SHEIN Sellers
SHEIN Marketplace moves fast — viral SKUs sell out in hours and handling time SLAs are tight. If you are still picking and packing your own orders, you will miss the wave. We pull SHEIN orders into our WMS, ship same-day from Paramount, CA, and push tracking back so your seller performance stays in good standing while you focus on next drops.
What syncs automatically
SHEIN Marketplace orders flow into our WMS so fast-fashion sellers can keep up with the volume without missing handling SLAs.
Orders
SHEIN Marketplace orders pull into our WMS in real time so high-velocity SKUs ship before the buyer changes their mind.
Inventory
Quantities sync back to SHEIN listings so trending items do not oversell when they go viral.
Tracking
Tracking numbers upload to each SHEIN order on dispatch to satisfy handling time and tracking validity requirements.
SKU mapping
SHEIN variant SKUs map to your master SKUs so size and color variations pick correctly under volume.
Why brands using SHEIN Marketplace choose 3PLGuys
Built for fast-fashion velocity
Apparel that sells in waves needs fast pick paths and same-day ship cutoffs. Our slotting and shift coverage keeps up with viral momentum.
Apparel-ready packing
Polybag packing, hangtag awareness, and folded-vs-rolled handling are standard. Your garments arrive looking sellable, not crumpled.
Handling time SLA protection
Same-day shipping for orders before our cutoff keeps your SHEIN handling time and on-time rate inside performance thresholds.
Variation-heavy SKU support
Apparel runs deep in sizes and colors. Our WMS handles thousands of variants per style without picking errors.

Apparel returns get inspected, restocked, or flagged for liquidation. Decisions log in your portal so refunds happen inside the return window.
