Overview

Amazon has published an updated guide outlining the full range of integration options available through its Multi-Channel Fulfilment (MCF) program. MCF allows sellers to use Amazon's fulfilment network to ship orders from non-Amazon sales channels, including independent websites, social media shops, and other marketplaces. For sellers looking to scale beyond Amazon without juggling multiple fulfilment providers, understanding these integration pathways could significantly simplify operations.

What MCF Actually Does

Multi-Channel Fulfilment lets sellers store inventory in Amazon's fulfilment centers and use that stock to fulfil orders from any sales channel — not just Amazon.com. When a customer orders from your Shopify store, your own website, or a social media marketplace, Amazon picks, packs, and ships the product using the same logistics infrastructure behind Prime delivery. The core benefit is inventory consolidation: instead of splitting stock across multiple warehouses or third-party logistics providers, everything lives in one place. This can reduce shipping costs, speed up delivery times, and eliminate the operational headache of managing separate fulfilment workflows for each channel.

Integration Options at a Glance

• Amazon-Built Apps — Free applications developed and maintained by Amazon that connect MCF directly to your ecommerce website with minimal technical setup.
• Third-Party Apps — Independent software tools that link MCF with ecommerce platforms, marketplaces, and order management systems, offering broader compatibility and more advanced features.
• Custom API Integrations — Direct access through the Selling Partner API (SP-API) or the legacy Marketplace Web Service (MWS) for fully customized fulfilment workflows.
• Order Management Connectors — Pre-built connectors that tie MCF into popular order management platforms for centralized fulfilment control.

Amazon's Own Free Apps

Amazon offers a suite of free integration apps designed for straightforward connections between MCF and popular ecommerce platforms. These are maintained by Amazon's development teams, so they tend to receive prompt updates when fulfilment systems change. Because there are no subscription fees, they represent the lowest-cost entry point for sellers who want to start fulfilling off-Amazon orders through MCF. The trade-off is fewer customization options compared to third-party alternatives, but for sellers running a single direct-to-consumer site alongside their Amazon storefront, the native apps are often the most practical choice.
