Amazon FBA (Fulfillment by Amazon) stores, packs and ships orders placed on Amazon.com, and makes those products eligible for Prime on Amazon. Amazon MCF (Multi-Channel Fulfillment) uses the same Amazon warehouses and inventory to fulfill orders from other channels, such as a Shopify store, Walmart Marketplace or TikTok Shop. The main difference is where the order comes from.
FBA is built for Amazon orders, and MCF extends Amazon’s network to everywhere else. FBA is usually the right choice for Amazon sales. MCF works well for brands that already use FBA and have modest off-Amazon volume, because it avoids running a second fulfillment operation.
As off-Amazon volume grows, MCF’s per-order fees, Walmart’s packaging and delivery rules, and the concentration of all inventory in one marketplace’s network become bigger factors. At that point many brands move to a third-party logistics provider (3PL) that runs DTC, marketplace and retail orders from one inventory pool, and keep FBA only where it earns its place.
What Is Amazon FBA?
Fulfillment by Amazon (FBA) is Amazon’s fulfillment program for orders placed on Amazon. Sellers ship inventory to Amazon’s fulfillment centers, and Amazon handles storage, picking, packing, shipping, customer service and returns for Amazon orders. FBA products are eligible for Prime on Amazon, which is a meaningful conversion driver.
FBA costs include referral fees on each sale, per-unit fulfillment fees based on size and weight, monthly storage fees and surcharges for aged inventory. For 2026, Amazon said FBA fees would increase by an average of $0.08 per unit sold, with most changes effective January 15, 2026. For a full breakdown of current rates, see our guide to Amazon FBA fees.
What Is Amazon MCF?
Amazon Multi-Channel Fulfillment (MCF) uses Amazon’s fulfillment network to ship orders from channels outside Amazon.com. A brand’s FBA inventory serves both Amazon orders and orders from its own website, other marketplaces and social commerce channels. Amazon describes MCF as white-label fulfillment with unbranded packaging, and lists standard and expedited shipping options.
MCF appeals most to brands that already sell through FBA and want to extend Amazon’s logistics to DTC and other channels without building a separate fulfillment operation. Amazon reports that sellers using MCF and FBA in a single inventory pool cut out-of-stock rates by an average of 19%.
Amazon FBM: one more option
FBM (Fulfilled by Merchant) means the brand handles Amazon fulfillment itself or through a third-party logistics provider. Orders are listed on Amazon but picked, packed and shipped outside Amazon’s network. FBM gives the most control over packaging, inventory and carriers, and requires the brand or its 3PL to meet Amazon’s shipping performance standards.
MCF vs. FBA vs. a Multichannel 3PL: Side-by-Side Comparison
| FBA | MCF | Multichannel 3PL | |
|---|---|---|---|
| Best for | Amazon-first sellers | FBA sellers with modest off-Amazon volume | Brands selling across DTC, marketplaces and retail |
| Channels supported | Amazon.com | Off-Amazon channels (Shopify, Walmart, TikTok Shop and others) | All channels, including Amazon through FBM or Seller Fulfilled Prime |
| Prime eligibility | Yes, on Amazon | Prime delivery available on the brand’s own website | Seller Fulfilled Prime on Amazon, if the 3PL qualifies |
| Packaging | Amazon-branded | Unbranded | Brand’s own packaging, inserts and kitting |
| Inventory | Held in Amazon’s network | Same pool as FBA | One pool held by the 3PL, with FBA replenishment as needed |
| Returns | Amazon handles Amazon returns | Brand is responsible; returns can be routed to Amazon | Handled by the 3PL under the brand’s policies |
| Customer service | Amazon handles for Amazon orders | Brand handles | Brand or 3PL, depending on the service |
| Pricing | Per-unit fees plus referral and storage fees | Per-order fees by size, weight, units and speed | Contracted rates based on volume and services |
The Real Cost of Amazon MCF in 2026
MCF fees are charged per order, based on size tier, weight, number of units and delivery speed. Single-unit orders cost the most per unit. During the 2026 holiday peak, Amazon’s published rate card lists a standard-speed, single-unit MCF fee of $7.53 for a small standard item of 4 oz or less, rising to $10.97 for a large standard item between 1 and 2 lb. These peak rates apply from October 15, 2026 to January 14, 2027.
Several other charges affect the final cost. Amazon applies a 3.5% fuel and logistics surcharge to US MCF fulfillment fees, adds a 100% surcharge for standard-size orders shipped to Alaska, Hawaii and US territories, and adds a per-unit fee for lithium battery items. Amazon’s 5% surcharge for blocking Amazon Logistics as the carrier, which Walmart orders require, is waived for MCF orders through January 14, 2027. On the savings side, Amazon’s MCF Preferred Pricing program offers FBA sellers 15% to 25% off fulfillment fees for the first six months through a mix of MCF discounts and FBA credits.
Product eligibility matters too. Amazon can refuse products that fall under its restricted product rules, so brands with hazardous, regulated or oversized items should confirm eligibility before planning around MCF.
Is Amazon MCF cheaper than a 3PL?
It depends on order profile and volume. MCF is often cost-effective for low off-Amazon volume, because the brand avoids setup costs and a second inventory location. For brands with steady DTC, wholesale or marketplace volume, a 3PL’s contracted rates, multi-unit order handling and custom packaging usually compare well against MCF’s per-order fees, especially for single-unit orders, which carry MCF’s highest per-unit cost. The fair comparison is total landed cost per order by channel, including surcharges, returns and the cost of stockouts.
Using MCF for Walmart, TikTok Shop and Shopify Orders
Amazon is making it easier to run other channels through its network. At Accelerate 2026, Amazon introduced multichannel selling tools in Seller Central that connect listings, orders and profitability across eBay, Shopify, TikTok and Walmart. Sellers can view unshipped orders from every channel, fulfill off-Amazon orders through Amazon and sync tracking back to the source channel. Amazon says the tools come at no additional cost and roll out gradually to US sellers over the coming months. Amazon also notes that more than 95% of independent sellers in its store already sell across multiple channels.
Shopify
Shopify merchants can select Amazon MCF as a fulfillment option from Shopify admin, link their Seller Central account and route orders to MCF automatically. Since September 2026, MCF merchants can also add Prime delivery and the Prime badge to their own websites at no cost beyond standard MCF fees. Amazon reports that early adopters ship more than 40% of eligible orders with Prime delivery on average.
TikTok Shop
TikTok Shop orders reach MCF through connector apps that link TikTok Shop to Seller Central and fulfill orders from FBA inventory automatically. Amazon’s MCF for TikTok Shop guide requires an active TikTok Shop seller account and an Amazon seller account with FBA inventory. Amazon recommends sending TikTok Shop returns to a seller-controlled address rather than an Amazon warehouse, which means brands still need a returns process outside Amazon’s network.
Walmart Marketplace
Walmart allows MCF, with conditions. Walmart’s shipping and fulfillment policy permits MCF only when orders ship in neutral packaging using unbranded delivery vehicles, with no logos or branding from another retailer. In practice, that means using MCF’s unbranded packaging and blocking Amazon Logistics as the carrier. Walmart also requires sellers to ship orders within two operational days unless an exemption applies, and to meet each order’s expected delivery date.
Walmart measures sellers on those requirements. Its seller performance standards require an on-time delivery rate of 90% or above, a valid tracking rate of 99% or above and a cancellation rate of 2% or below. A brand using MCF for Walmart orders is accountable for those metrics, even though Amazon is doing the shipping.
Data and Control Trade-Offs
MCF works by sending order details to Amazon so Amazon can ship them. That includes the customer’s name, shipping address and order contents for every off-Amazon order. Amazon’s MCF service terms limit how Amazon can use that personal data to fulfillment, customer service on the seller’s behalf, fraud prevention and legal compliance, and state that Amazon deletes it when a seller stops using MCF, unless the law requires otherwise. Brands should still understand what data leaves their systems and review the terms with their legal team, particularly for sensitive categories.
Inventory concentration is the second trade-off. When FBA and MCF share one inventory pool, every channel depends on Amazon’s network, capacity rules and fee changes. That pool makes stock easier to share, but it also means an inbound delay, a capacity limit or a peak-season fee change affects DTC, Walmart and TikTok Shop at the same time as Amazon. Brands that keep some inventory outside Amazon have a fallback when that happens.
Branding and customer experience are the third. MCF’s unbranded packaging solves the Amazon box problem, but it is still generic packaging. Brands that rely on custom boxes, inserts, samples or kitting for DTC and subscription orders can’t deliver that experience through MCF.
Returns and customer service are the fourth. Under the MCF terms, the brand is responsible for accepting and processing returns and issuing refunds, and Amazon has no customer service obligations toward shoppers beyond passing along inquiries and fulfillment status. MCF handles the box, and the brand still owns the customer relationship and everything that follows the delivery.
When FBA Makes Sense
FBA is the right call when Amazon is a brand’s primary channel. Prime eligibility on Amazon and Amazon-native fulfillment are hard to match for Amazon orders, and FBA removes most of the logistics work for those sales. FBA also suits early-stage brands that want operational simplicity, and high-velocity SKUs where fast delivery and Prime placement drive conversion on Amazon.
When MCF Makes Sense
MCF makes sense for brands that are primarily FBA sellers and want to extend fulfillment to a smaller DTC store or secondary marketplace without managing a separate 3PL. It also makes sense when off-Amazon order volume is low enough that MCF’s per-order fees stay modest, and when the brand’s products don’t depend on custom packaging.
When a Multichannel 3PL Makes More Sense
A dedicated 3PL becomes the stronger option when off-Amazon volume grows to the point where MCF fees are material, or when the brand needs to meet Walmart’s delivery standards, ship wholesale and retail orders, or deliver a branded unboxing experience. It also makes sense when the brand wants inventory and fulfillment decisions made around the whole business, not one marketplace.
The most efficient setup for many growing brands is one inventory pool managed by a 3PL that fulfills every channel. Cart.com runs DTC, marketplace and retail orders from one inventory pool, so stock isn’t split across separate operations or stranded in the wrong network. Brands can keep FBA for Amazon where it performs well, replenish FBA from the same pool, and fulfill DTC, Walmart, TikTok Shop and wholesale orders with their own packaging and policies. Commerce Services by Cart.com connects that fulfillment operation to marketplace management, so inventory, advertising and channel decisions work from the same data.
Can I use FBA and a 3PL at the same time?
Yes, and many multichannel brands do. A common setup keeps FBA for Amazon orders, uses a 3PL for DTC, other marketplaces and retail, and has the 3PL replenish FBA from the main inventory pool. That gives the brand Prime eligibility on Amazon, branded fulfillment everywhere else and a fallback if Amazon inventory runs low.
Frequently Asked Questions
What is the difference between Amazon MCF and FBA?
FBA fulfills orders placed on Amazon.com and makes products Prime-eligible on Amazon. MCF uses the same Amazon warehouses and inventory to fulfill orders from other channels, such as Shopify, Walmart Marketplace and TikTok Shop. FBA is for Amazon orders, and MCF extends Amazon’s network to off-Amazon orders.
Does Amazon MCF ship in Amazon-branded boxes?
No. Amazon describes MCF as white-label fulfillment with unbranded packaging. That matters for Walmart Marketplace, which only allows MCF orders shipped in neutral packaging with no other retailer’s branding. MCF does not support custom branded boxes or inserts.
Can I use Amazon MCF for Walmart orders?
Yes. Walmart allows MCF when orders ship in neutral packaging using unbranded delivery vehicles, which in practice means blocking Amazon Logistics as the carrier. Amazon’s 5% surcharge for blocking Amazon Logistics is waived for MCF orders through January 14, 2027. Sellers remain responsible for Walmart’s standards, including a 90% on-time delivery rate and a 99% valid tracking rate.
How much does Amazon MCF cost in 2026?
During the 2026 holiday peak, from October 15, 2026 to January 14, 2027, Amazon’s standard-speed MCF fee for a single-unit order ranges from $7.53 for a small standard item of 4 oz or less to $10.97 for a large standard item between 1 and 2 lb, plus a 3.5% fuel and logistics surcharge. Multi-unit orders cost less per unit, and expedited delivery costs more.
Who handles returns for Amazon MCF orders?
The seller does. Under Amazon’s MCF terms, the brand is responsible for accepting and processing returns and issuing refunds. Returns can be routed back to an Amazon fulfillment center so sellable units go back into inventory, and Amazon recommends a seller-controlled return address for TikTok Shop orders.
When should a brand switch from MCF to a 3PL?
A brand should consider a 3PL when off-Amazon volume makes MCF’s per-order fees material, when it needs custom packaging or kitting, when it sells wholesale or retail, or when it wants inventory outside Amazon’s network. Many brands keep FBA for Amazon and use a 3PL with one inventory pool for every other channel.
