> **TL;DR:** Over 95% of independent sellers in Amazon's store also sell through other retail channels, so the multi-channel question is settled in practice. Brands still have to choose which channels, in what order, and what each one asks of the operation behind them. Amazon holds the largest pool of demand and the tightest fee structure. eBay's US marketplace grew 24% last quarter on collectibles, motors, fashion, and refurbished goods. Vertical marketplaces such as Wayfair and Chewy own a category and make the brand ship every order. Walmart Marketplace is growing fastest from a small base. TikTok Shop concentrates its revenue in a few hundred sellers. Faire, distributors, and retail change the unit you ship from a parcel to a case pack. Choose by fit and stage, then build a fulfillment layer that serves all of them.

In Amazon's [2025 Small Business Empowerment Report](https://sellingpartners.aboutamazon.com/impact), the company states that over 95% of independent sellers in its store also sell their products in other retail channels. More than 75,000 of those sellers cleared $1 million in sales last year, and the average US independent seller did more than $375,000 in Amazon's store alone.

Consider that from the other direction. The sellers doing real volume on the largest marketplace in the country rarely sell only there. The strategic debate over "Should I go multichannel?" has been settled with an emphatic "Yes!" for some time now.

The harder choices come next: which channels to run, in what order, and what each one asks of the operation behind them. Every channel brings demand and a set of unique operating requirements. Amazon wants a brand's inventory sitting in its buildings. Faire wants a case pack. TikTok wants units out the door the afternoon a video lands. Each one lands as a different job on a warehouse floor. A brand that adds channels faster than it adds operational capability pays in chargebacks, cancellations, and late-shipment metrics.

## What Each Channel Asks of Your Warehouse

Channel strategy gets discussed as a marketing decision and executed as a fulfillment decision. The marketing half is straightforward, since demand is where the shoppers are. The fulfillment half decides whether the channel makes money.

**The shipping unit changes.** A DTC order is one or two units in a mailer. A wholesale order is a case pack, or multiple cases on a pallet. A retail purchase order arrives with a routing guide and a compliance manual.

**Who holds the inventory.** FBA holds it for you and charges a premium for the privilege. Walmart Fulfillment Services (WFS) does the same. Your own storefront and most wholesale options require you to hold it, which means one pool of stock has to serve orders with wildly different fulfillment expectations.

**The speed clock.** Amazon and Walmart both rank listings partly on delivery promise. A TikTok video that gains traction creates a spike inside a day. A boutique's opening order on Faire can ship this week.

**The cost of a return changes.** A refund on one channel costs a brand several times what the same refund costs on another. That difference shows up in the settlement report on the back end rather than in the published fee schedule.

## Your Own Storefront Is the Foundation

Shopify reported gross merchandise volume of $115.6 billion in its second quarter of 2026, up 32% year over year, its fifth consecutive quarter of GMV growth above 30%. Inside that quarter, business-to-business GMV grew 76%, more than twice the rate of the platform overall. International grew 37%, and offline grew 32%. These are global, platform-wide figures covering enterprise accounts and point of sale, so your mileage will surely vary.

Wholesale is where Shopify merchants are expanding fastest, and wholesale fulfillment is a different operational problem from DTC: pallets instead of parcels, retail compliance, EDI, routing guides, and chargebacks for a label in the wrong place.

Your storefront is your foundation. You set the prices, you own the customer relationship (along with the data behind it), and no third party can change your economics between quarters. We made the longer version of this case in [My Bet Is on Shopify](/blog/shopify-is-the-winner), and nothing since has changed our read.

**Best fit:** every brand, at every stage. The other channels hang from the storefront.

## Amazon Still Holds the Demand

Third-party sellers account for an estimated 69% of Amazon's roughly $440 billion in US gross merchandise volume, according to Marketplace Pulse. No other channel in the country puts that many buyers in front of a brand that nobody has heard of yet.

The cost of that access keeps climbing. I covered the fee load, the payment timing changes, and the two federal cases in [Amazon Squeezing Sellers](/blog/amazon-squeezing-sellers-federal-lawsuits-decade-of-fees). Amazon sets the fees, raises them annually, and does its best to penalize you unless you use all of Amazon's other upstream services. Our article on [Amazon Storage Fees vs 3PL Storage Costs](/blog/amazon-storage-fees-vs-3pl-storage-costs-2026) works through the economics of splitting inventory between FBA and a warehouse of your own.

Amazon still commands a place in the plan, but with eyes open regarding these issues. Basically, because of its size and influence on consumer behavior, you simply have to be there. However, your long-term valuation will hinge almost entirely on how you perform elsewhere, because the margin Amazon has already claimed for itself will never be coming back.

**Best fit:** products with existing search demand, at any volume, run by an operator who tracks fees at the unit level and holds additional inventory somewhere Amazon does not control.

## eBay's US Marketplace Is Growing Again

People tend to overlook eBay in their mental rankings of the major online marketplaces in the US. eBay's last four reported quarters add up to $43.8 billion of US GMV, against the roughly $15 billion Marketplace Pulse estimates for all of Walmart's third-party marketplace over a year. eBay also sells nothing of its own, so every dollar of that volume belongs to a seller.

The business is growing again, and growing fastest at home. eBay moved $22.4 billion of goods in the quarter ending June 30, 2026, up 15% year over year. [The US accounted for $11.7 billion of that and grew 24%](https://investors.ebayinc.com/investor-news/press-release-details/2026/eBay-Inc--Reports-Second-Quarter-2026-Results/default.aspx), against 6% growth internationally.

The growth concentrates in specific categories. eBay's focused categories, which the company defines as collectibles, motors, fashion, and refurbished goods, grew 26% and passed 40% of total GMV for the first time. Resale of pre-owned and refurbished goods, which eBay calls recommerce, grew more than 20%, and so did consumer-to-consumer sales. The platform counts 136 million active buyers, including 16 million enthusiast buyers spending roughly $3,600 each over a trailing twelve months.

eBay differs from Amazon and Walmart in one structural way: it runs no fulfillment arm of comparable scale, so the seller ships every order. The categories that grow fastest there compound the problem. A refurbished unit, a used part, and a graded collectible each get photographed and described individually. Each ships in a box sized to the item and occupies a bin one unit deep. A picker who can grab twelve identical units off one shelf will spend three times as long finding twelve different ones.

**Best fit:** parts and accessories, collectibles, refurbished and off-price inventory, discontinued lines, and overstock a brand would rather not discount on its own storefront. A brand sitting on aging inventory has a buyer on eBay that it does not have anywhere else.

## Walmart Marketplace Is Growing Fastest, But From a Small Base

Walmart's US third-party marketplace grew nearly 50% year over year in the quarter ending April 30, 2026, which CFO John David Rainey described on the earnings call as its fastest growth in two and a half years. Marketplace Pulse [estimates that marketplace at roughly $15 billion](https://www.marketplacepulse.com/articles/walmart-marketplace-growth-reaches-fastest-pace-in-years), about 10% of Walmart's $150 billion US e-commerce business, against an estimated 200,000 active sellers.

Notably, units shipped same-day or next-day through WFS grew nearly 150% in that quarter, and Walmart can now reach roughly 60% of US households within 30 minutes. Delivery speed shapes where listings appear in Walmart search the way it does on Amazon, so WFS likely earns a place alongside FBA in your fulfillment stack.

Walmart's marketplace holds roughly 200,000 active sellers. Amazon.com [held about 500,000 as of March 2026](https://www.marketplacepulse.com/articles/the-paradoxical-dependence-of-amazon-its-sellers), down from 584,000 a year earlier, and those sellers compete for attention inside a catalog that has had thirty years to fill up. A new listing on Walmart gets past fewer rivals to reach the same shopper. Walmart's third-party advertising spend rose more than 50% in the same quarter, which shows how fast other sellers are competing that advantage away.

**Best fit:** consumable and value-priced goods, household categories, and brands that already win on price and delivery speed. A brand carrying a premium price and a story to tell will find less room here than on its own storefront.

## TikTok Shop Rewards a Small Number of Sellers

TikTok Shop sells the idea that the algorithm decides, so any seller can win. Marketplace Pulse tracked close to 100,000 US TikTok Shop sellers and found [the top 1% driving 60% of tracked lifetime GMV](https://www.marketplacepulse.com/articles/on-tiktok-shop-1-of-sellers-drive-60-of-gmv). The top 0.1%, fewer than 90 sellers averaging over $100 million in lifetime sales each, took more than a quarter of it. The bottom half of sellers by this metric contributed roughly 0.1%.

TikTok Shop runs on discovery and interruption, not on search. A shopper searches only for products they already know exist, so a novel product has to interrupt someone to create awareness before search traffic will ever reward it. For an innovative or premium product, TikTok Shop reaches buyers further up the funnel than any marketplace built on search.

The payoff also shows up outside TikTok. Measurement firm Fospha reports that TikTok Shop's return on ad spend runs [20% higher once a brand counts its Amazon sales](https://www.fospha.com/blog/beyond-the-checkout-measuring-the-true-impact-of-marketplaces) alongside in-app checkouts. Digital Commerce 360 and TikTok's own commerce data put [73% to 78% of TikTok Shop purchases as incremental](https://www.measureprotocol.com/insights/tiktok-shop-impulse-purchase-behavior-ecommerce-search-intent), meaning the buyer would not have bought the same item elsewhere that week. Our own read matches. Brands nowhere near the top of the platform still see branded search and conversion rate climb on Amazon after a TikTok launch, because a video creates the demand and the shopper finishes the purchase where they already have an account.

The operational demand here differs from every other channel on this list. A video lands and the orders arrive within hours. To convert that spike, a brand has to ship ten times its normal volume the same day, with no warning to staff for it.

**Best fit:** beauty, personal care, apparel, and impulse-priced products with a creator strategy already running, backed by fulfillment capacity that flexes within hours.

## Wayfair, Chewy, and the Vertical Marketplaces

A brand in the right category can find more buying intent on a marketplace that owns that category outright than on any general one.

Wayfair owns home. It runs on a wholesale model rather than a referral fee: a supplier sets the wholesale cost, Wayfair sets the retail price the shopper sees, and orders arrive through the Partner Home portal. Fulfillment splits two ways. A supplier either ships each order from its own warehouse or places inventory in Wayfair's CastleGate network. Goods shipped out of Wayfair's own fulfillment centers [account for 25% of its revenue](https://www.supplychaindive.com/news/wayfair-castlegate-logistics-offering-multichannel-service/758661), which leaves roughly three quarters of the business shipping from suppliers.

Chewy runs a curated marketplace in pet, where approved brands list products and ship from their own warehouse or their 3PL. Best Buy's marketplace, built out during its fiscal 2026, [turned over about $300 million in GMV in the fourth quarter](https://www.digitalcommerce360.com/2026/03/06/best-buy-online-marketplace-profit-2026) across more than 1,100 third-party sellers. More than 80% of its marketplace returns come back through a store. Target Plus admits sellers by invitation. Newegg holds the PC components audience. Houzz sells home design to people already planning a renovation. Etsy remains the largest handmade, vintage, and craft-supply marketplace in the country. A maker who fits it reaches buyers who came looking for something that is not mass-produced.

In each case, the marketplace owns the customer relationship, and the brand ships every order itself, against on-time and tracking rules that read more like a retail vendor agreement than a DTC checkout. Miss the ship-by date and the penalty arrives as a chargeback.

Connecting to the largest of these is its own project. A brand does not integrate with Nordstrom, Kohl's, Macy's, Target, or Chewy directly. It connects through an EDI network such as SPS Commerce, or through a dropship platform such as DSCO or CommerceHub. That connection carries the purchase orders, the acknowledgments, the advance ship notices, and the invoices, all on the retailer's schedule. These integrations don't typically come cheap, either. Budget for this before counting the revenue.

**Best fit:** brands whose category has a dominant specialist, and particularly brands selling bulky goods (like a sofa table or 30-pound bag of dog food) that cost too much to move through a general marketplace.

## Wholesale Changes the Unit You Ship

Faire connects independent retailers with brands, and an order from a boutique arrives as a case pack bound for a shelf rather than a single unit bound for a doorstep. I wrote about the channel in [Faire: The Wholesale Channel Nobody Talks About](/blog/faire-wholesale-channel-nobody-talks-about). To make wholesale work, you must build out separate fulfillment paths to support both your DTC and B2B orders.

JOOR does the same for apparel and accessories, connecting brands to retail buyers who place seasonal orders.

Wholesale also changes the shape of the revenue. One retail order replaces dozens of individual sales. The margin per unit is lower, and the shop keeps the customer relationship, not you.

**Best fit:** brands whose products sell better in person than in a search result, brands whose category already has shelf space to win, and brands ready to diversify beyond their online-first roots.

## Distributors, Chain Retail, and the Store Down the Street

Founders hear wholesale and picture a chain buyer. Chains are part of it. In many categories, though, a distributor decides whether a product reaches a shelf.

Food and beverage runs this way almost entirely. Sysco alone operates 333 distribution centers and [serves approximately 670,000 customer locations on more than $84 billion of sales](https://sysco.com/en-us) in the fiscal year that ended June 27, 2026. A beverage brand does not sell to 670,000 restaurants one at a time. It sells to a distributor, and the distributor sells to the restaurants. Toys and games work through distribution the same way, and so does hardware, where co-ops and regional distributors supply thousands of independent stores that no brand could call on directly.

A distributor asks for different things than a marketplace does. Case packs built to its standard, pallet configurations that fit its racking, and a GTIN on every unit. Lead times run in weeks, and the minimum order arrives as one large purchase order. The distributor also keeps the retail relationship and a share of the margin, which is the price of reaching accounts a brand cannot reach alone.

Chain retail sits at the far end of the same spectrum, with routing guides, EDI transactions, on-time-in-full scorecards, and chargebacks when a carton label lands two inches off. That channel deserves its own article, and it will get one.

Start at the other end. A brand can walk its case packs into the restaurants and independent stores in its own city and learn most of what a distributor or a chain will later ask. Does the case pack size match how a small store actually buys? Does the retail price survive the margin stack? Do they reorder? Twenty local accounts answer those questions in a quarter, at a volume where a mistake only costs a case of product.

**Best fit:** any brand in a category that already moves through distribution, and every brand as a local test. Local retail costs little to try and teaches the wholesale operation before the wholesale operation matters.

## Who Pays for the Return on Each Channel

Return economics separate the channels more sharply than fee schedules do.

On Amazon, a refund costs a seller three ways. Amazon keeps the fulfillment fee you paid to ship the unit. It charges a return processing fee in many categories. It then refunds the referral fee minus a [refund administration fee](https://sellercentral.amazon.com/help/hub/reference/external/GDC3U6FWF4JJJJC7), which is the lesser of $5.00 or 20% of that referral fee. The unit itself may come back unsellable.

Faire runs the opposite arrangement on a retailer's first order. In its own words to brands, "Faire takes on that return risk, not the brand," which is the mechanism that persuades a shop owner to try an unfamiliar product line.

eBay hands the policy to the seller. A seller sets the return window, or declines remorse returns entirely. [eBay's Money Back Guarantee](https://www.ebay.com/help/policies/ebay-money-back-guarantee-policy?id=4210) still covers an item that never arrives, arrives damaged, or does not match the listing. A seller who accepts no returns gives the buyer three calendar days after delivery to open that claim.

Your own storefront puts the entire cost on you and hands you the entire policy. You decide the return window, who pays the shipping, and whether a replacement goes out before the original comes back. That control is the reason a brand with a high return rate often makes more margin on its own site at a lower price than on a marketplace at a higher one.

## Match the Channel to Your Stage

Sequence beats breadth. A brand running four channels badly loses to the same brand running two channels well, because every channel consumes operational attention that does not scale with revenue.

**Under roughly 1,000 orders a month:** the storefront, plus one marketplace that matches the product. Two demand sources are enough to learn from, and adding a third mostly adds administration. With that said, it is never too early to test wholesale demand in your own community, so consider starting that outreach now.

**Roughly 1,000 to 5,000 orders a month:** bring on the second marketplace, and start measuring contribution margin by channel. If you haven't already moved fulfillment out of your back room to a professional operation, now is the time.

**Roughly 5,000 to 15,000 orders a month:** add a channel with a different shipping unit, usually wholesale or retail, because parcel-only growth eventually runs into its own ceiling. A brand at this volume has enough order history to forecast, enough margin to absorb a mistake, and enough complexity that one inventory pool serving every channel becomes a requirement.

**Above that:** the harder question is whether inventory, data, and labor can serve every channel from one operation without a person reconciling spreadsheets among them.

## The Part You Control

Every platform changes its terms on its own schedule. Amazon raises its fees, TikTok rewrites its algorithm, Walmart changes its PPC ads program, and you find out when it reaches your margin.

You own the fulfillment underneath every one of those channels. One operation keeps a single pool of inventory and one system of record. It ships a parcel today, a case pack tomorrow, and a retail purchase order carrying a compliant label on the right corner of the carton. Build it, and adding a channel becomes a decision about demand. Skip it, and every channel you add takes a piece of the margin from the ones you already run.

Finally, consider this: if your best channel doubled next quarter, and your second-best channel asked for pallets instead of parcels, would the same operation handle both? If the answer is no, that constraint deserves attention before the next channel does.
