Walmart Seller Center vs Amazon Seller Central: Fees, Workflow, and What Transfers

Walmart Seller Center is cheaper to keep open than Amazon Seller Central and harder to get into. Walmart’s pricing page states that Walmart Marketplace and WFS run with “zero setup, monthly, or hidden fees” (data checked 2026-08-12), while Amazon publishes a Professional plan at “$39.99 / month”. But Walmart’s registration requirements ask for a “Business Tax ID(s) or Business License Number (SSN not accepted)” and a “History of marketplace or eCommerce success” — there is no individual-seller on-ramp equivalent to Amazon’s $0.99-per-item plan.

The second answer matters more for your P&L: your Amazon reviews do not come with you, and neither does your rank. Product data, images and inventory move over in an afternoon. Demand does not.

This guide prices both back offices against their official pages on 2026-08-12, then walks five gates and an item-by-item transfer audit.

The Framework: Five Gates Before You Open a Second Channel

Work these in order and stop at the first hard no. Most sellers who regret opening Walmart failed Gate 1 or Gate 5 and only discovered it after building the catalog.

1. Entry — can your business entity actually be approved?
2. Category economics — does your referral rate leave a margin at Walmart’s lower price points?
3. Fulfillment — WFS, your own warehouse, or nothing?
4. Transfer — what carries over from Amazon and what has to be rebuilt?
5. Capacity — do you have the hours and the SKU depth to feed a second channel?

Gate 1: Can Your Business Get Approved?

This is where the two platforms diverge most sharply, and where old advice ages badly. Walmart’s seller registration guide and its pre-registration requirements guide (guide last updated Apr 16, 2026; both checked 2026-08-12) list what you must bring:

• A “Business Tax ID(s) or Business License Number (SSN not accepted)” — a sole proprietor operating on a Social Security number cannot register.
• Supporting documents that verify your business name and address, plus a copy of a personal ID.
• “History of marketplace or eCommerce success” — Walmart still asks for a track record.
• Products carrying GTIN/UPC numbers from a GS1 company prefix.
• A fulfillment path: WFS, or another business-to-consumer U.S. warehouse that can process returns.

Walmart states that “Business verification can vary from a few minutes to two business days,” and new sellers are placed under a New Seller Payment Hold while sales history is established.

Amazon, by contrast, publishes an Individual plan at “$0.99 / item sold” alongside the Professional plan (Amazon’s pricing page, checked 2026-08-12) — the practical difference is covered in the Individual vs Professional plan guide. The takeaway is not “Walmart is closed.” It is that Walmart screens on business legitimacy and prior sales record, so an established Amazon seller with an LLC and two years of order history is the profile Walmart is built to accept, and a side-hustle account is not.

Gate 2: Does the Referral Fee Work in Your Category?

Both marketplaces charge a percentage of the sale, and both vary it by category. Walmart’s pricing page publishes the full contract-category schedule; Amazon’s rates run 5% to 45% by category with a $0.30 minimum in most categories (both checked 2026-08-12). Selected Walmart rates, quoted from that page:

Two structural differences are worth more than any single number.

Walmart uses price-tiered rates far more than Amazon does. Four of the categories above change rate at a price threshold. If your items cluster just above one of those breaks — a $21 apparel item, an $11 supplement — your effective rate jumps 5 to 7 points. Model the price you intend to list at, not the category headline; Amazon’s breakdown is in the Amazon referral fee guide.

The ceiling is lower at Walmart. Nothing in the published schedule exceeds 20%, and that only on the first $250 of a jewelry sale; Amazon tops out at 45%. Most general merchandise lands near 15% on both, so the referral line alone rarely decides the question — check your exact product type against the contract-category schedule (last updated Mar 9, 2026).

Gate 3: WFS or Your Own Warehouse

Walmart Fulfillment Services is the FBA analogue, and its published rate card is simpler than Amazon’s because Walmart bills on shipping weight alone rather than on a size-tier grid. From the pricing page, checked 2026-08-12:

Storage is $0.75 per cubic foot per month from January through September. October through December carries the same rate for inventory held 30 days or less, with an additional $1.50 per cubic foot per month beyond that, and inventory over 12 months old bills at $2.25 per cubic foot per month. The mid-weight bands between 21 and 50 lb. are on the same page — read them off the current rate card rather than interpolating.

The line item that actually differs is inbound. Walmart’s WFS cost estimator guide states that WFS “fulfillment fees cover receiving, stowing, picking, packing and inbound shipping,” and that the fee structure also covers customer support and non-seller-fault returns (checked 2026-08-12). Freight into the fulfillment network is a separate cost you carry on the Amazon side. Amazon’s fulfillment fees are dimension-driven and published against a size-tier table — see the FBA size tiers guide and run your unit through the free FBA fee calculator before comparing anything, because a single quoted FBA number is an example, not a rate.

Practical read: light, compact products model easily against WFS’s flat sub-$6 bands and often land close to FBA. Heavy or awkward products must be priced on each platform individually, because Amazon’s size-tier logic and Walmart’s weight logic diverge.

Gate 4: What Actually Transfers from Amazon

This is the gate sellers skip, and the reason a Walmart launch takes three weeks instead of three days. Here is the honest audit.

Three of those deserve detail.

Images need a re-export, not a copy-paste. Walmart’s image guidelines call for 2200 × 2200 pixel main images, with 1500 × 1500 the minimum that still enables zoom, a 1:1 square on seamless white, files under 5MB, and JPEG, JPG, PNG or BMP but not GIF. The main image may not carry watermarks, your name or your logo, and no image may include retailer logos, promotional claims or non-English text. The page states no DPI or PPI requirement; noncompliance “may result in products being unpublished” (checked 2026-08-12).

Pricing is enforced, not just competitive. Walmart’s pricing rules describe a reference price built from external signals including competitor match prices, historical selling price, the Buy Box winner’s price and Walmart’s own online and store prices. An offer priced substantially above that reference can lose its Add to Cart button — buyers reach it only through More Seller Options — or be unpublished outright, and folding shipping into the item price is called out as a way sellers trip this. Walmart’s Buy Box weighs the offer’s price, shipping fee, delivery speed, the seller’s performance metrics and the customer’s experience (checked 2026-08-12) — a separate scorecard from Amazon’s featured offer (Amazon Buy Box guide). Seller Center also ships a built-in Repricer that watches other e-commerce sites, not only Walmart.com, unlike the third-party stack most Amazon sellers run (Amazon repricer comparison).

Reviews have a partial path — and it does not start on Amazon. Walmart’s free Review Syndication program publishes reviews collected on your own website to the matching Walmart.com item, provided the item ID and UPC exist in both catalogs. You may syndicate through one authorized partner only. Amazon reviews are not eligible. A seller with a DTC store carrying review history has a head start; a pure Amazon seller starts at zero stars, the single biggest hidden cost of the move.

Common Mistakes Amazon Sellers Make on Walmart

• Treating the catalog push as the launch. Multichannel tools publish listings; they do not create demand. Tool selection is covered separately in the multichannel listing software guide — that page compares the software, this one compares the two back offices behind it.
• Copying Amazon prices verbatim. Walmart’s reference-price machinery reads external sites. A price that is fine on Amazon can quietly suppress the Add to Cart button here.
• Launching the whole catalog. Every SKU adds content maintenance, inventory splitting and a second support queue. Start with the 10 to 20 SKUs with the best margin and the most stable supply.
• Assuming FBA units cover Walmart orders. Inventory held in Amazon’s network is not available to Walmart’s; you either split stock, enroll in WFS separately, or ship yourself.
• Reusing Amazon main images unchanged. Overlays and text that survive on Amazon breach Walmart’s main-image rules.
• Budgeting zero ad spend because the channel is “free to open.” No monthly fee is not the same as free traffic.

Pre-Launch Checklist

• Business tax ID or business license in hand — not an SSN
• Documented marketplace or e-commerce sales history ready to submit
• GTIN/UPC coverage confirmed for every SKU you intend to list
• Referral rate looked up for your exact contract category and your intended price point
• WFS versus self-fulfillment priced per unit, not per catalog
• Images re-exported at 2200 × 2200, main images stripped of overlays, logos and watermarks
• Price checked against your own listings on every other channel you sell on
• Ad budget and campaign structure planned as a new build, not a migration
• First 10–20 SKU shortlist agreed, with a 90-day stop-loss

Frequently Asked Questions

Is there a monthly fee for Walmart Seller Center?

No. Walmart’s pricing page states that Walmart Marketplace and WFS operate with “zero setup, monthly, or hidden fees” (data checked 2026-08-12). You pay referral fees on completed sales, plus WFS fees if you use it. Amazon charges “$39.99 / month” for its Professional plan.

Can I sell on Walmart without a business license?

Not on the terms Walmart publishes. The registration requirements list a “Business Tax ID(s) or Business License Number (SSN not accepted)” and supporting documents verifying business name and address (checked 2026-08-12). Amazon’s Individual plan has no equivalent business-entity gate.

Does Walmart still approve sellers manually?

Walmart’s own requirements page still lists a “History of marketplace or eCommerce success” among what you need before signing up, and business verification is stated as taking “a few minutes to two business days” (checked 2026-08-12). Treat it as a screened application, not an open signup.

Do my Amazon reviews transfer to Walmart?

No. Walmart’s Review Syndication program syndicates reviews collected on your own website, not reviews collected on another marketplace. Every listing you launch on Walmart starts with no review history.

Are Walmart’s fees really lower than Amazon’s?

On subscription, yes — Walmart publishes no monthly fee. On referral fees they are comparable for most general merchandise, both clustering near 15%, though Walmart’s published ceiling is 20% against Amazon’s 45%. The gap that decides profitability is usually advertising and fulfillment, not the referral line. For the broader channel-economics question, see DTC ecommerce vs Amazon.

Conclusion: Who Should Open the Second Channel

Open Walmart if you are an incorporated seller with 20 or more stable SKUs, gross margin above roughly 35%, a supplier who can hold buffer stock for a second channel, and someone who can own a second support queue. Those sellers get a channel with no monthly fee, a fulfillment option that bundles inbound freight, and materially less seller competition per listing than Amazon.

Skip it if any of these is true: fewer than about 10 SKUs (the fixed setup work does not amortize), margins under 25% (Walmart’s price enforcement removes your room to hold price), no one available for a second inbox, or no budget for launch advertising. Opening a channel you cannot feed produces a stale catalog with suppressed offers and zero reviews — a net drag, not a hedge.

The honest framing is that Walmart is not a cheaper Amazon. It is a second demand pool with a lower fixed cost, a stricter door, a stricter pricing regime, and a review ledger that starts at zero.
