Overview

Amazon's Multi-Channel Fulfillment (MCF) service lets sellers use their FBA inventory to fulfill orders from non-Amazon sales channels. Within Seller Central, sellers can customize key MCF settings including packing slip details and carrier preferences. Understanding these options helps sellers maintain brand consistency across channels and manage fulfillment costs effectively.

Key Points / What Sellers Need to Know

• Packing slip customization — Sellers can personalize the merchant name and free-text message that appear on MCF packing slips, allowing brand-consistent fulfillment across all sales channels.
• Merchant name field — This controls whose name appears on the packing slip and should reflect your business name or website, not your Amazon seller name.
• Packing slip text field — A free-text area where sellers can include return policies, customer service contact information, or thank-you messages tailored to their off-Amazon customers.
• Block Amazon shipping option — Sellers can choose to prevent MCF orders from being delivered by Amazon's own logistics network, though this comes with a 5% surcharge on those orders.
• Account-level vs. order-level control — The Amazon shipping block can be configured globally in MCF settings or overridden on a per-order basis through the order creation page or MCF API.
• Surcharge waiver in effect — The 5% surcharge for blocking Amazon shipping on MCF orders is currently waived until June 14, 2027.

Customizing Your Packing Slip

When fulfilling orders from your own website or other marketplaces through MCF, the packing slip is often the only branded touchpoint your customer receives. Seller Central provides two editable fields within the FBA settings section. The merchant name field should contain your business or website name so that customers recognize who fulfilled their order. The packing slip text field allows you to add a custom message, and Amazon recommends using it to communicate return instructions, customer support contact details, or a brief thank-you note. For example, a seller might write something like: "Thank you for ordering from YourStore.com. For returns, please visit yourstore.com/returns." These settings apply to all MCF orders by default and help reinforce your brand identity when Amazon is handling the logistics behind the scenes.
