Amazon multi-channel fulfillment (MCF) is a service that lets sellers use Amazon's FBA warehouses and logistics network to fulfill orders placed on non-Amazon sales channels, including Shopify, Walmart, TikTok Shop, and a brand's own website. Orders pull from the same FBA inventory pool, with delivery options ranging from two to five business days inside the US.
Amazon multi-channel fulfillment (MCF) extends Amazon's fulfillment infrastructure beyond the Amazon marketplace. If you already store inventory in Amazon's network for FBA, MCF lets that same inventory ship customer orders from Shopify, BigCommerce, Walmart, eBay, TikTok Shop, SHEIN, or your own DTC site — without standing up a separate 3PL or warehouse operation.
For brands juggling multiple sales channels, MCF can feel like a shortcut. One inventory pool, one operator, one set of SLAs. But the model carries trade-offs that matter once you understand how it actually prices, packages, and ships orders — especially for DTC brands manufacturing in Asia who are weighing MCF against direct fulfillment from the point of production.
You send inventory to Amazon's fulfillment centers the same way you would for FBA. When an order comes in from a non-Amazon channel, you submit a fulfillment request through Seller Central, the MCF API, or a third-party integration (Shopify and Walmart have native connections as of Amazon's September 2025 expansion).
Amazon picks, packs, and ships the order from the nearest fulfillment center. You pick the delivery speed at order creation:
Inventory is shared across FBA and MCF by default — meaning the units you store for Amazon orders are the same units fulfilling Shopify orders. You can also block MCF from pulling FBA inventory if you want to keep pools separate.
MCF charges a per-unit fulfillment fee based on item size, weight, and selected delivery speed. Storage fees are billed monthly per cubic foot, with higher rates from October through December. Unlike FBA, MCF orders are not subject to Amazon referral fees because the sale happens off-platform.
Pricing varies significantly by category and speed tier. A standard-size apparel item shipped at two-day speed will cost meaningfully more than the same item at five-day speed. For accurate cost modeling, you'll want to run your own SKUs through Amazon's MCF rate calculator — published rate cards change frequently.
MCF works when you're already operating heavily inside Amazon's ecosystem and want a simple way to fulfill spillover channels without onboarding a separate 3PL. It's a reasonable bridge for brands with low non-Amazon volume that doesn't justify dedicated infrastructure.
The model breaks in a few predictable ways:
The fundamental difference is where your inventory sits and when capital gets committed.

For brands manufacturing in Asia, the legacy MCF path means paying for inventory, shipping it across an ocean, paying duties, and storing it — all before a single non-Amazon order is placed. Direct fulfillment from the point of manufacture compresses that cycle by keeping inventory upstream and committing units only when orders come in.
This is the same model Shein and Temu use to move billions of units globally, and it's the structural reason their cash conversion cycle is fundamentally different from a brand running on bulk freight plus MCF.

MCF is a workable patch for brands deep inside Amazon's ecosystem. It's not a solution for the structural problem most DTC brands face: capital trapped in inventory sitting in domestic warehouses, months before it sells. Portless ships orders directly from your manufacturer in Asia to customers in 75+ countries in five to eight days — no bulk freight, no upfront duties on unsold stock, no Amazon-branded boxes.
