Amazon FBA and Walmart WFS are marketplace-run fulfillment programs: you send inventory into the marketplace's network and it stores, picks, packs, ships, and handles returns for a fee. Target Plus is the opposite model — an invite-only marketplace with no Target-run fulfillment, where sellers must hit Target's delivery standards from their own network. Choosing between them is less a pricing question than an operating-model question: who runs execution, and who owns the inventory pool.
That distinction is easy to miss from the storefront, where all three look like one more channel to switch on. Operationally they pull your supply chain in different directions. FBA and WFS want your inventory inside their walls, priced and prioritized for their marketplace. Target Plus wants proof that your own fulfillment infrastructure can match the delivery experience Target's guests expect from Target itself. Brands that expand across all three without a plan end up with fragmented stock pools, duplicate safety stock, and an invitation from Target they cannot operationally accept.
This comparison covers how the three programs differ as fulfillment models, what they cost at the structural level, how inventory placement works in each, what you can and cannot do with each pool across other channels, and when a brand should run marketplace-native versus channel-agnostic fulfillment.
How Do Amazon FBA, Walmart WFS, and Target Plus Differ as Fulfillment Models?
The core split: FBA and WFS are outsourced execution, Target Plus is graded self-execution. Everything else — fees, placement, multi-channel flexibility — follows from that.
| Dimension | Amazon FBA | Walmart WFS | Target Plus |
|---|---|---|---|
| Who fulfills orders | Amazon's network | Walmart's network | The seller, from own warehouse, 3PL, or 4PL |
| Marketplace access | Open registration | Application with approval | Invite-only, curated assortment |
| Fulfillment fees to the marketplace | Size- and weight-tiered, plus storage and surcharges | Weight-tiered, plus storage; no monthly or setup fee | None — you fund your own network |
| Inventory placement | Amazon distributes stock; inbound placement fees apply | Walmart distributes across WFS centers | You choose warehouse locations and stock levels |
| Multi-channel use of the pool | Yes, via Multi-Channel Fulfillment (MCF), including Walmart orders with conditions | Yes, via Multichannel Solutions for Amazon, eBay, and DTC orders | Inherently channel-agnostic — the same network serves every channel |
| Delivery standard | Prime badge eligibility | TwoDay delivery tags | Ship within 24 hours, deliver within 5 business days via approved carriers |
| Customer returns | Handled by Amazon | Handled by Walmart | Accepted by Target in stores and by mail; reverse logistics coordinated with the seller |
The table rewards a second read. Notice that Target Plus is the only program with zero fulfillment fees — and the only one where that number is misleading, because the cost has not disappeared, it has moved onto your own P&L. Notice too that both marketplace-run programs now officially support fulfilling other channels, which changes the old assumption that FBA stock is trapped stock.
What Do the Three Programs Cost?
Fee schedules change every year, so anchor any decision to the official rate cards rather than screenshots in blog posts. The structural differences, however, are stable.
Amazon FBA stacks a category referral fee (paid by every seller, fulfilled or not) with FBA fulfillment fees tiered by size and weight, monthly and peak storage fees, and event-driven charges such as inbound placement and low-inventory-level fees. For 2026, Amazon's official announcement put the increase at an average of $0.08 per unit sold with no new fee types — but in April 2026 a 3.5% fuel and logistics surcharge was applied to FBA fees in the U.S. and Canada, extending to MCF and Buy with Prime in May, as fuel costs climbed. The current schedule lives on Amazon's Selling Partner fee pages, and the Amazon seller playbook covers how the pieces fit together.
Walmart WFS mirrors the structure with simpler mechanics: a referral fee on each sale, weight-tiered fulfillment fees starting at $3.45 for items up to one pound, storage at $0.75 per cubic foot from January through September with peak-season additions, and surcharges for apparel, hazmat, and low-price items. There are no monthly or setup fees, and Walmart publishes the full schedule on its WFS pricing page. Long-term storage escalates sharply — items held beyond 450 days now trigger a $7.50 per cubic foot monthly fee — which is Walmart telling you plainly that WFS is a flow-through network, not a warehouse.
Target Plus charges a category-based commission on each sale and nothing for fulfillment or storage, because Target performs neither. Your cost side is your own network: warehousing, pick-and-pack labor, and parcel contracts with the approved carriers. The honest comparison is therefore not FBA fees versus WFS fees versus zero. It is marketplace-run fee schedules versus your own cost to serve at Target's required standard — and for brands that already operate a fulfillment network for DTC or retail, the marginal cost of adding Target Plus volume can be lower than either marketplace program.
How Does Inventory Placement Work in Each Program?
Placement is where the control trade-off becomes concrete.
With FBA, you ship to Amazon-designated inbound locations and Amazon spreads inventory across its network to position stock near demand. The inbound placement service fee prices that convenience: send everything to one location and pay Amazon to distribute it, or split shipments across multiple inbound points yourself for reduced or waived fees. Capacity limits and storage utilization surcharges add further pressure to keep your FBA position lean and fast-turning.
With WFS, the mechanics are similar — you ship to designated WFS facilities and Walmart handles distribution across its fulfillment centers — with fewer placement levers to pull and, correspondingly, fewer placement fees to manage.
With Target Plus, placement is entirely your decision, and your warehouse footprint effectively is your delivery promise. Hitting five-business-day delivery nationwide on ground service requires inventory positioned within reach of your demand centers; the 24-hour ship window requires receiving, slotting, and wave-planning discipline at each site. This is the structural reason Target's invitation process weighs fulfillment capability so heavily: on Target Plus there is no marketplace network to compensate for a thin one of your own.
Can One Inventory Pool Serve All Three Channels?
Partially — and the rules changed recently, so this is worth getting current on.
FBA stock is no longer Amazon-only stock. Through Multi-Channel Fulfillment (MCF), Amazon fulfills orders from your own site and other marketplaces out of the same FBA pool. The notable shift: Walmart's marketplace policy now permits MCF-fulfilled orders, provided packages ship in blank, unbranded packaging and Amazon Logistics is blocked as the carrier. Amazon has waived the standard 5% carrier-blocking surcharge until January 14, 2027, which reads as a direct bid to become the fulfillment layer for Walmart sellers. The constraints still matter: MCF fees run above equivalent FBA fees, you carry Walmart's delivery-window metrics on Amazon's execution, and your channel data consolidates inside Amazon's ecosystem.
WFS answers with Multichannel Solutions, which fulfills orders from Amazon, eBay, and your own DTC site out of WFS inventory, with two-day or three-to-five-day service levels. The same logic and the same caveats apply in mirror image. The Walmart marketplace playbook covers where WFS and Multichannel Solutions fit in a Walmart growth plan.
Neither program is designed to backstop Target Plus. Target's 24-hour ship window, approved-carrier requirement, and curation of seller operations make marketplace-run fulfillment a poor structural fit, and in practice Target Plus orders ship from seller-controlled networks. If Target Plus is in your channel roadmap, some portion of your inventory must live in infrastructure you control.
The deeper issue with pooling everything into one marketplace's network is gravity. Inventory inside FBA or WFS is priced, prioritized, and reported to serve that marketplace first. Multi-channel programs rent you flexibility at a premium; they do not give you operational control of placement, packaging, carrier choice, or the unified data underneath.
What Does Target Plus Demand From Your Own Network?
Target Plus deserves its own operational readiness check, because it is the program brands most often misjudge. It is invite-only and deliberately small — a curated set of more than 1,500 brands, per Shopify, with Target selecting partners for brand strength, category fit, and assortment gaps, and typically one seller per SKU. Target announced plans in March 2025 to grow the marketplace from roughly $1 billion in GMV in 2024 to more than $5 billion by 2030, adding hundreds of brands per year — so invitations are expanding, but curation is not loosening.
Operationally, the bar is specific: a U.S.-registered entity with EIN, W-9, and DUNS number; EDI or API integration for orders and inventory; shipment within 24 hours of purchase; delivery within five business days through approved carriers; and performance metrics that feed continued eligibility. Miss the standard consistently and the invitation gets withdrawn. The upside is equally specific: access to Target's guest base with minimal SKU-level competition, returns accepted through Target stores, and a marketplace that functions more like a retail partnership than an open auction. Our Target Plus overview covers the program in depth, and the Target Plus seller guide walks through onboarding step by step.
When Should You Run Marketplace-Native vs Channel-Agnostic Fulfillment?
The decision tracks channel count and control requirements, not brand size.
Marketplace-native fulfillment (FBA, WFS) fits when:
- One marketplace generates the clear majority of your revenue, and the Prime badge or TwoDay tag measurably drives conversion in your category
- Your catalog is compact and fast-turning, keeping storage and long-term fees manageable
- Your team is small and outsourced execution buys focus you cannot otherwise afford
Channel-agnostic fulfillment fits when:
- You operate three or more channels — marketplaces, DTC, retail, B2B — and duplicate safety stock across marketplace pools is quietly inflating working capital
- Target Plus, or any seller-fulfilled retail program, is in your roadmap and needs infrastructure you control
- You need packaging, carrier, and data control that marketplace-run programs structurally cannot offer
In practice most scaled multi-channel brands land on a hybrid: a lean FBA position sized to protect Prime economics on hero SKUs, with a channel-agnostic network handling everything else — DTC, B2B, Target Plus, and overflow. The implementation work sits in the split: forecasting demand by channel, setting replenishment cadence into FBA and WFS from your core pool, integrating EDI and marketplace APIs so inventory positions reconcile daily, and routing each order to the node that hits its channel's delivery standard at the lowest landed cost. That orchestration layer — not the warehouses themselves — is what most brands are actually missing.
How Pi-Commerce Runs Marketplace Fulfillment for International Brands
For international brands entering the U.S., this three-program puzzle usually arrives all at once, without the domestic operating history that makes each program's trade-offs familiar. Pi-Commerce operates as a 4PL built for exactly that position: warehouse operations with B2C and B2B fulfillment serving marketplace and retail channels from one inventory pool, EDI connectivity through SPS Commerce, and NetSuite ERP as the financial backbone. The team brings Target retailer operating knowledge as a Target certified vendor — including Target Plus onboarding — alongside Walmart vendor experience and Walmart FSP certification, so the delivery standards described above are requirements the team operates against, not abstractions. Visibility runs from factory production through ocean transit, warehouse, and last mile to final delivery, with a Unified Data Center platform in development to consolidate that view further.
