How to Set Up Amazon Multi-Channel Fulfillment (MCF)

What MCF is and how it works

Amazon Multi-Channel Fulfillment (MCF) lets you leverage Amazon's fulfillment network for orders placed outside of Amazon. If you sell on Shopify, your own website, eBay, Walmart, or any other channel, MCF lets you fulfill those orders using the same FBA inventory sitting in Amazon's warehouses.

The flow: a customer orders on your Shopify store → you (or your integration) submit the order to Amazon via the MCF API → Amazon picks, packs, and ships the product from their fulfillment center → the customer receives the order. The key difference from FBA: these orders don't carry the Prime badge and don't contribute to your Amazon BSR.

MCF supports three shipping speeds: Standard (3-5 business days), Expedited (2-3 days), and Priority (next day). Costs increase with speed, and the service is available in the US, UK, and several other marketplaces.

MCF vs. standard FBA

MCF uses the same inventory and warehouses as FBA, but the pricing and terms differ:

Higher fulfillment fees: MCF charges approximately 20-30% more per unit than standard FBA fulfillment. This premium covers the additional complexity of non-Amazon order processing.

Shared inventory: MCF and FBA draw from the same inventory pool. A busy day on Shopify reduces stock available for Amazon customers. This requires careful inventory planning, especially during peak seasons like Prime Day or Q4.

No Prime benefits: MCF orders don't earn Prime badges, don't count toward your Amazon sales rank, and don't build your Amazon review velocity. They're purely fulfillment transactions.

MCF vs. third-party logistics (3PL)

The core trade-off is simplicity vs. cost and branding control:

MCF advantages: Single inventory pool (no splitting between FBA and a 3PL), Amazon's reliable delivery network, no 3PL relationship to manage, easy setup if you're already using FBA.

3PL advantages: Lower per-order costs (typically 20-30% cheaper than MCF), custom branded packaging and inserts, branded packing slips, no inventory sharing risk with your Amazon channel, and more control over the customer experience.

MCF pricing breakdown

MCF pricing is based on product size tier and shipping speed. As of 2026:

Standard size (under 20 lbs):

• Standard shipping (3-5 days): $5.85-8.20 depending on weight
• Expedited (2-3 days): $7.50-10.50
• Priority (next day): $10.00-15.00

Oversize items: Significantly higher, $10-25+ depending on dimensions and weight.

Compare these to your 3PL's all-in cost (storage + pick & pack + shipping) to determine which is more economical for your specific product mix and order volume.

Using MCF with Shopify

Amazon offers a free Shopify app called "Buy with Prime" that integrates MCF directly into your Shopify store. When enabled, Shopify orders can be automatically routed to Amazon for fulfillment. The app handles order submission, tracking number updates, and inventory sync.

Alternative integrations include ShipStation (which can route orders to MCF based on rules), Deliverr (now part of Flexport), and custom API integrations via Amazon's SP-API. For sellers expanding from Amazon to Shopify, MCF provides the easiest path since you're already using FBA.

The branding trade-off is significant for DTC brands. If your Shopify store emphasizes brand experience with custom packaging, inserts, and unboxing moments, MCF's generic packaging undermines that. Consider MCF only if your DTC customers prioritize fast, reliable delivery over branded experiences.

When MCF makes sense

Good fit: You're just starting multi-channel sales (under 200 orders/month from non-Amazon channels), you want simplicity over optimization, your brand doesn't rely on custom unboxing experiences, and you don't want to manage a separate 3PL relationship.

Not a good fit: Your non-Amazon volume exceeds 500 orders/month (3PL becomes significantly cheaper), you're a DTC brand where packaging is part of the experience, you need to keep Amazon and non-Amazon inventory separate to prevent stockouts during peak Amazon periods, or you're already established with a 3PL that meets your needs.

The middle ground: some sellers use MCF as a backup fulfillment option. Primary fulfillment goes through their 3PL, but if the 3PL has delays or stockouts, orders can be rerouted to MCF automatically. This hybrid approach provides reliability without making MCF your primary fulfillment channel.
