Amazon FBA performs 3PL functions but is marketplace-native fulfillment. Amazon MCF is a 3PL service. See how FedEx, Shopify, and ShipBob compare.
The answer changes across two Amazon services. Amazon FBA performs 3PL functions, but it is marketplace-native fulfillment rather than a traditional channel-neutral 3PL. Amazon Multi-Channel Fulfillment (MCF) explicitly calls itself a 3PL service for off-Amazon orders. Classify the service, not the parent-company logo.
Amazon FBA is 3PL-like, but it is not a traditional channel-neutral 3PL. Fulfillment by Amazon stores inventory, picks and packs orders, ships products, handles customer service, and processes returns. Those are core third-party logistics functions.
Amazon's own FBA page calls FBA a program for outsourcing order fulfillment to Amazon. The reason for the narrower "marketplace fulfillment" label is the relationship between the parties: Amazon runs both the marketplace where the sale occurs and the fulfillment program that completes the order.
A traditional 3PL is independent of the storefront. It connects to channels such as Shopify, Walmart, TikTok Shop, and Amazon, then fulfills orders according to the merchant's routing rules. For the broader category definition, see what counts as a third-party logistics provider.
FBA fulfills orders placed through Amazon, while Amazon MCF fulfills orders placed on off-Amazon channels. Amazon's MCF FAQ explicitly describes Multi-Channel Fulfillment as a 3PL service for brand websites, social stores, and other marketplaces.
| Service | Order source | Official classification | Practical role |
|---|---|---|---|
| Amazon FBA | Amazon marketplace orders | Amazon fulfillment program | Stores and fulfills seller inventory for Amazon orders, with Prime eligibility for qualifying offers |
| Amazon MCF | Brand sites, social commerce, and other marketplaces | 3PL service | Uses Amazon inventory and fulfillment capacity for off-Amazon orders |
FBA and MCF can draw from the same inventory pool. The inventory does not become "traditional 3PL inventory" just because MCF ships it, but the service relationship changes: MCF is Amazon acting as an outside fulfillment provider for a sale made somewhere else.
| Entity or service | Closest category | What the service does | Is it a 3PL? |
|---|---|---|---|
| Amazon FBA | Marketplace fulfillment | Stores and fulfills inventory for Amazon orders | 3PL-like, not a traditional channel-neutral 3PL |
| Amazon MCF | Third-party logistics | Fulfills off-Amazon orders from Amazon's network | Yes |
| FedEx parcel delivery | Carrier / 2PL-like transport | Moves packages after pack-out | No |
| FedEx Fulfillment | Third-party logistics | Stores inventory and picks, packs, ships, and handles returns | Yes |
| Shopify | Commerce platform | Routes orders and connects merchants to outside fulfillment partners | No |
| ShipBob | Third-party logistics | Stores inventory and fulfills orders across ecommerce channels | Yes |
Classify the named service, not the logo. Amazon, FedEx, and Shopify each sit across multiple parts of the commerce and logistics stack, so one parent-company label produces the wrong answer.
Amazon FBA is not a 4PL because FBA executes fulfillment instead of managing a merchant's portfolio of logistics providers. Amazon defines a fourth-party logistics provider as a strategic control layer that can manage multiple 3PLs and other supply-chain partners.
Amazon as a company offers marketplace, fulfillment, transportation, warehousing, and supply-chain services. That breadth does not make every Amazon service a 4PL. When the question is about FBA, the accurate label is marketplace-native fulfillment with 3PL functions. When the question is about MCF, Amazon's own label is 3PL service.
FedEx parcel delivery is a carrier service, but FedEx Fulfillment is a 3PL operation. The carrier side moves a packed shipment from origin to destination. FedEx Fulfillment receives and stores merchant inventory, integrates with sales channels, and picks, packs, ships, and processes returns.
FedEx's current fulfillment workflow shows the distinction clearly: merchants send inventory into FedEx facilities before orders arrive. FedEx then performs the warehouse work and can hand the parcel to FedEx or another carrier. The warehouse operation is 3PL work; the final transportation leg is carrier work.
Shopify is not a 3PL. Shopify is the commerce platform and fulfillment-partner interface, while outside providers perform the physical logistics. Shopify's current Fulfillment Network connects merchants to Flexport and to other 3PL apps.
Shopify lists Amazon MCF, Bigblue, DHL Fulfillment, GoBolt, Mayple, Shipfusion, and ShipBob among the 3PL services available through its Fulfillment Network. Shopify can route orders and inventory data to those providers, but the provider stores the inventory and fulfills the order.
ShipBob is a traditional ecommerce 3PL. Merchants send inventory to ShipBob's fulfillment network, connect their sales channels, and use ShipBob to store, pick, pack, ship, and manage returns.
ShipBob is a useful control example because the company is not also the marketplace where the customer checks out. The merchant keeps the storefront and customer relationship while ShipBob performs the logistics. See the ShipBob review for the provider's network, pricing model, and merchant fit.
Use three questions to classify the service:
| Question | If yes | Likely category |
|---|---|---|
| Does the provider store inventory and pick and pack customer orders? | The provider executes outsourced fulfillment | 3PL |
| Does the provider only move a shipment after someone else packed it? | The provider supplies a transport mode | Carrier / 2PL-like service |
| Does the provider manage several 3PLs and other supply-chain partners for the merchant? | The provider acts as the strategic control layer | 4PL |
Marketplace fulfillment creates the main edge case. FBA performs the warehouse tasks of a 3PL, but Amazon is also the marketplace where the customer buys. MCF is cleaner to classify because the customer buys elsewhere and Amazon fulfills the order as an outside service.
The label matters because it tells you which part of the operating model you are outsourcing. FBA is built around Amazon sales and Prime eligibility. MCF extends Amazon's network to other channels. A traditional 3PL can support a broader channel mix and merchant-controlled workflows.
The detailed choice depends on product size, channel mix, packaging, service requirements, and cost. The Amazon FBA review covers FBA itself, while the vetted 3PLs for Amazon sellers guide covers prep, replenishment, and multichannel providers.
Amazon FBA performs the physical work associated with a 3PL, but its marketplace-native role makes "marketplace fulfillment" the more precise label. Amazon MCF is explicitly a 3PL service for off-Amazon orders. FedEx can be either a carrier or a 3PL depending on the business unit. Shopify is the platform connecting merchants to 3PL partners. ShipBob is a conventional ecommerce 3PL.
The shortest reliable rule is simple: classify the service being purchased, then ask who stores the inventory, who picks the order, where the sale occurs, and whether another company is coordinating multiple providers.
Amazon FBA performs 3PL functions such as storage, picking, packing, shipping, customer service, and returns. Because Amazon also operates the marketplace where the sale occurs, FBA is more precisely classified as marketplace-native fulfillment rather than a traditional channel-neutral 3PL.
Yes. Amazon explicitly describes Multi-Channel Fulfillment as a 3PL service for off-Amazon orders. MCF can fulfill orders from brand websites, social-commerce stores, and other marketplaces while drawing from the same inventory pool used for FBA.
The answer depends on the Amazon service. FBA is marketplace fulfillment with 3PL functions, and MCF is an explicitly labeled 3PL service. FBA is not a 4PL because it executes fulfillment instead of coordinating several 3PLs as the merchant's strategic control layer.
FedEx parcel delivery is carrier service, not 3PL fulfillment. FedEx Fulfillment and FedEx Supply Chain are different: those operations can receive and store inventory, integrate sales channels, pick and pack orders, ship parcels, and process returns, which is a 3PL model.
No. Shopify is an ecommerce platform. Shopify's Fulfillment Network connects merchants to outside 3PL services such as Flexport, Amazon MCF, DHL Fulfillment, Shipfusion, and ShipBob. Those providers hold inventory and fulfill orders; Shopify supplies the commerce and connection layer.
Yes. ShipBob is an ecommerce 3PL because merchants send ShipBob inventory and ShipBob stores, picks, packs, ships, and processes returns across connected sales channels. ShipBob is independent of the storefront where the customer makes the purchase.
FBA is a fulfillment program, not a building. Amazon operates fulfillment centers where enrolled FBA inventory is stored and orders are picked, packed, and shipped. The fulfillment center is the facility; FBA is the service and operating system that uses those facilities.
Yes. A traditional 3PL can fulfill merchant-fulfilled Amazon orders or work upstream by receiving, inspecting, labeling, storing, and replenishing inventory for FBA. The required setup depends on the seller's Amazon program, Prime requirements, and the 3PL's FBA-prep capabilities.
Sloane covers ecommerce operations, fulfillment strategy, and the practical tradeoffs operators face when selecting a 3PL partner.
A 3PL (third-party logistics provider) stores your inventory and ships your orders for you. Most ecommerce brands adopt one at 500-1,500 orders/month. The term spans four operating models: distributed DTC, category specialist, enterprise, and marketplace fulfillment.
