Guide · China fulfillment models
A coordination layer, a dropshipping agent and an inventory 3PL are three distinct models for moving goods from China to overseas buyers. A coordination layer coordinates parcels a merchant has already bought from its own suppliers — receiving, consolidating, repacking and forwarding them per shipment, without holding inventory. A dropshipping agent sources and purchases products on the merchant’s behalf, then fulfills orders. An inventory 3PL stores the merchant’s stock in its warehouses and picks, packs and ships from that stock.

This is a comparison of models, not of vendors. As reference points: the dropshipping-agent model is what platforms such as CJdropshipping operate (they source products and fulfill orders on the seller’s behalf); the inventory-3PL model is what fulfillment networks such as ShipBob operate (they store the seller’s inventory and ship orders from their warehouses). Both are legitimate models — they solve different problems than a coordination layer does.
| Dimension | Coordination layer | Dropshipping agent | Inventory 3PL |
|---|---|---|---|
| Definition | Coordinates the China leg for parcels the merchant bought from its own suppliers: receiving, value-added services, consolidation, dispatch, tracking, settlement. | Sources, purchases and fulfills products on the merchant’s behalf; the agent sits between the merchant and the factories. | Receives the merchant’s bulk inventory into its warehouse, then picks, packs and ships each order from stored stock. |
| Who owns the supplier relationship | The merchant. It selects suppliers, places orders and pays them directly; the coordination layer never handles the purchase payment. | Largely the agent. The merchant typically chooses products from the agent’s catalog or sends links; the agent buys from factories it selects. | The merchant sources and buys goods itself, then transfers the stock into the 3PL’s custody. |
| Inventory commitment | None. Parcels flow through per shipment; there is no storage commitment. | Usually none for the merchant — goods are bought per order or held briefly by the agent. | Required. The model only works with stock pre-positioned in the 3PL’s warehouse, with storage fees while it sits. |
| Pricing model | Pay per shipment: a packed quote plus itemized service fees per parcel or consolidation. | Product price + service margin + shipping, quoted by the agent; the product cost includes the agent’s markup. | Receiving + storage (per volume per month) + pick-and-pack fee per order + shipping. |
| Quality and cost control of goods | Full merchant control — the merchant negotiates its own factory prices and specs. | Depends on the agent’s sourcing; the merchant does not usually see the factory price. | Full merchant control over sourcing; the 3PL only handles what it receives. |
| Best fit | Established merchants with multiple China suppliers who want per-shipment consolidation, prep and forwarding without warehousing. | New sellers who have no suppliers yet and want product sourcing and fulfillment handled in one place. | Sellers with predictable volume on stable SKUs who want fast local dispatch and accept storage costs. |
If the problem is “I need products and someone to ship them,” an agent model bundles sourcing and fulfillment. The trade-off is that the factory price and quality decisions sit with the agent, not with you.
If you have stable SKUs and predictable volume, pre-positioning inventory buys the fastest last-mile dispatch. The trade-off is capital locked in stock plus storage fees whether the goods sell or not.
If you already buy from multiple China suppliers and the pain is receiving, consolidating, prepping, forwarding, tracking and reconciling those parcels — a coordination layer does exactly that scope, per shipment, without taking over purchasing or requiring inventory.
The models also combine: some merchants start with an agent, move to owning their suppliers plus a coordination layer for the China leg, and add a destination-country 3PL only for their fastest-moving SKUs.
WooliiPorter operates the coordination-layer model: merchants keep their own China suppliers and pay them directly, and WooliiPorter coordinates receiving, value-added services (with mandatory photo evidence), consolidation, FBA first-leg, dispatch and unified tracking — settled per shipment as explainable fee line items. It is not a buying agent, never handles the purchase payment, and never forces an inventory commitment.
WooliiPorter now offers both fulfillment modes on that foundation. Merchants can start supplier-direct with pass-through forwarding — no stocking at all — and, as volume grows, optionally hold merchant-owned inventory at the China warehouse and dispatch fulfillment orders from it. Ownership of the goods stays with the merchant in both modes, stocking is always opt-in, and storage is billed transparently from the same immutable stock ledger that computes inventory levels. This does not change the three model definitions above: WooliiPorter remains a technology-driven coordination layer, with optional stocking as an extension rather than a pivot to an inventory-led 3PL.
