Industry Standard Definition
View Official Definition
Multichannel Fulfillment (MCF) is an Amazon fulfillment program where sellers store inventory in Amazon’s fulfillment centers and use that same stock to ship orders from non-Amazon channels— including their own website, marketplaces, and social commerce platforms.
— Amazon Multi-Channel Fulfillment Documentation (Accessed 2025)
Operationally, MCF reuses the FBA storage, picking, packing, and carrier network but routes shipments to customers whose orders originate on systems such as Shopify, WooCommerce, Walmart Marketplace, eBay, Etsy, or TikTok Shop.
MCF Program Scope & 2025 Configuration
View Core Program Settings
| Dimension | 2025 MCF Pattern | Notes |
|---|---|---|
| Inventory Source | Shared with FBA inventory | MCF pulls from the same FC stock used for Amazon FBA listings. |
| Eligible Channels | Webshops, marketplaces, social commerce | Typical: Shopify, WooCommerce, BigCommerce, eBay, Etsy, Walmart, TikTok Shop. |
| Delivery Speeds | Standard, Expedited, Priority | Speeds vary by region and service level; not always the same as Prime. |
| Packaging Options | Amazon-branded or unbranded (no-Amazon-logo) packaging | Unbranded packaging often used to avoid cross-channel branding conflicts. |
| Billing Model | Per-unit fulfillment + storage + surcharges | Fee structure similar to FBA, with MCF-specific rate cards by size / weight. |
| Policy Dependencies | FBA inbound rules, storage limits, IPI | MCF performance is constrained by the same FBA capacity and compliance rules. |
Regional Nuance — MCF in US, EU & UK (2025)
View Regional Differences
| Region | Program Notes | Key Expectations |
|---|---|---|
| United States (US) | Largest MCF footprint with dense FC network and strong carrier integrations for 2–5 day coverage. | Sellers often use MCF as a backup or overflow for DTC and marketplace orders, while managing IPI score and storage surcharges closely. |
| United Kingdom (UK) | MCF routes across a compact geography, simplifying 1–2 day delivery, but subject to UK VAT and post-Brexit import rules. | Brands must align MCF shipments with UK VAT invoicing, returns handling, and Royal Mail / courier expectations. |
| European Union (EU) | Often paired with Pan-EU FBA for multi-country coverage. MCF shipments interact with OSS / IOSS VAT frameworks. | Businesses must align stock locations, VAT registrations, and IOSS numbers to avoid tax and import mismatches when shipping cross-border within the EU. |
| Cross-Border from China | Inventory typically flows into US/EU FBA/MCF via ocean or air freight. Subject to UFLPA, Section 301, and de minimis enforcement. | MCF performance depends on compliant inbound routing—incorrect HTS, origin, or paperwork can delay inventory and stall all multichannel orders. |
MCF Workflow Components — OMS to Amazon FC (2025)
View MCF Workflow Structure
| Component | Examples | Primary Fulfillment Function |
|---|---|---|
| Order Capture & OMS | Shopify, WooCommerce, Walmart, eBay, TikTok → OMS | Aggregates orders from all channels and applies routing rules (MCF vs 3PL vs in-house). |
| API / Integration Layer | Amazon SP-API, MCF API, 3PL WMS API | Sends order data and shipping options to Amazon MCF while syncing inventory back to each channel. |
| Inventory Pooling | Shared FBA / MCF inventory, safety stock buffers | Centralizes stock but requires careful allocation to avoid FBA stockouts and oversells. |
| Fulfillment Execution | Amazon FC picking, packing, carrier handoff | Uses FBA infrastructure to prepare and ship orders to end customers on non-Amazon channels. |
| Tracking & Status Updates | MCF tracking feeds, channel notifications | Pushes tracking numbers back to OMS / channel to close the loop on customer notifications. |
| Returns & Reverse Logistics | MCF returns workflows, 3PL returns center, RMA | Handles refunds, restocking, and disposition across multiple sales channels. |

Maxwell Anderson, Editor-in-Chief & Data Director, WinsBS Research:
“MCF is not a replacement for a full 3PL stack—it is a strategic extension of FBA capacity. The most common failures we see are not about Amazon shipping speed, but about:
• poor inventory pooling between FBA, MCF, and external 3PLs
• misaligned delivery promises on Shopify / Walmart vs MCF service levels
• zero buffers for FBA restock limits and IPI changes
• no redundancy when FCs throttle inbound or change regional routing
High-performing brands treat Amazon MCF as one of several nodes in a multi-warehouse design: Amazon FCs for certain SKUs or regions; 3PL warehouses for DTC, B2B, and value-added services. This is where an OMS and a Prime-capable 3PL partner become critical.”
- Multi-warehouse fulfillment across US hubs (Dallas, Portland, New Jersey) alongside FBA / MCF.
- Unified OMS / WMS integrations with Amazon SP-API and major carts.
- FBA & MCF prep services, cartonization, and compliant inbound routing from Asia.
- Centralized returns handling and B2B / crowdfunding fulfillment beyond what MCF covers.

MCF FAQ — Common Questions
How is MCF different from FBA?
FBA covers orders placed on Amazon—storage, picking, packing, shipping, and customer service. MCF uses the same inventory and FC network to ship orders from non-Amazon channels such as your own website or other marketplaces. MCF fees and delivery speeds are separate from standard FBA Prime promises.
Can I use MCF for Shopify or Walmart orders?
Yes. Many brands connect Shopify, Walmart, eBay, and other channels to MCF via OMS or direct apps. Orders flow into Amazon’s FCs, which then ship to end customers using the MCF rate card and service levels. You must ensure your site’s delivery promises match actual MCF transit times.
Does MCF use Amazon-branded packaging?
By default, MCF may use Amazon-branded packaging in many regions, but unbranded options are increasingly available. Brands concerned about cross-channel branding or marketplace rules often choose unbranded packaging or route sensitive orders through an external 3PL instead.
Should I rely only on MCF instead of a 3PL?
For small catalogs or early-stage stores, MCF can be a quick way to gain reliable outbound shipping. However, it does not replace a full 3PL for B2B shipments, crowdfunding waves, custom packaging, kitting, returns processing, or multi-region warehouse design. Most mature brands use a hybrid approach combining MCF with dedicated 3PL fulfillment.
