Hi @Seller_EDBEkvsotsAlM,

Yes, you can use Multi-Channel Fulfillment (MCF) to fulfill orders from other platforms using your FBA inventory! Let me share what I found in the help pages.

According to Multi-Channel Fulfillment: Fulfill orders for your sales channels, MCF lets you "leverage Amazon's fulfillment network and expertise to pick, pack, and deliver orders from all your ecommerce channels."

The good news is that if you're already using FBA, you won't need any additional setup. The help page mentions that MCF orders "will be fulfilled from the same pool of inventory at Amazon fulfillment centers that is used for your FBA orders."

A few helpful things to know:

• Your orders will ship in unbranded packaging without Amazon branding (see "Unbranded packaging" section in Supply Chain Portal: Fees, settings, and support)
• There are two delivery speeds: Standard (3 business days) and Expedited (2 business days)
• You can check the current fees at Fulfillment fees for Multi-Channel Fulfillment orders

By the way, new MCF fees just went into effect on January 15, 2025, so make sure to review the current rates when planning your pricing strategy.

To make things easier, Amazon offers integration tools to help automate your eBay orders. You might want to check out the MCF Integration Selection tool mentioned in the help pages.

Hope this helps you get started!
