If you're looking at software for Amazon FBA sellers who want to add Walmart, here's the short answer: most tools solve half the problem. They get your listings live and your inventory synced across channels. Almost none of them tell you whether the Walmart order you just shipped through WFS actually made you money once fees, ads, and returns are subtracted. ## Key Takeaways ●      Walmart Marketplace crossed 200,000 active sellers in mid-2025 (up from 160,000 in 2024), and the pace shows no sign of slowing. ●      Software for Amazon FBA sellers moving to Walmart falls into two buckets: multichannel listing/sync tools (Sellbrite, CedCommerce, Linnworks) and profit-visibility tools that show whether the new channel is adding real margin. ●      WFS and FBA charge similar [referral fee](https://sellerview.ai/blog/amazon-referral-fee-explained) ranges, but different fulfillment and storage math - model it before you ship inventory. ●      More than half of Amazon sellers already sell on a second marketplace, so Walmart expansion is now normal operating behavior, not an experiment. ●      A tool that lists your product on Walmart doesn't tell you if that sale was profitable. That's a separate job, and most sellers don't have software doing it. ## At a Glance **Fact** **What It Means for You** **200,000+ active Walmart sellers (mid-2025), up ~25% YoY** Fast-growing channel that is still far less crowded than Amazon **WFS referral fee: 6-15% by category** Roughly in line with Amazon's referral fee ranges **WFS fulfillment fee: starts at $3.45/unit (standard tier)** A separate line item on top of the referral fee **WFS storage: $0.75/cu ft/month, up to $7.50/cu ft/month after 450 days** Aged inventory gets expensive fast, plan your sell-through **54% of Amazon sellers already sell on a second marketplace** Walmart expansion is mainstream, not experimental, in 2026 **Sellerview.ai starts at $15/month** Tracks true SKU-level profit across Amazon and Walmart together ## Why Amazon Sellers Are Adding Walmart Right Now Walmart's third-party marketplace added 44,000 new sellers in just the first five months of 2025, compared to 59,000 for all of 2024 combined - a clear acceleration. The platform now hosts more than 200,000 active sellers, up from about 160,000 the year before. This isn't a niche move anymore. Jungle Scout's 2026 seller survey found that 54% of Amazon sellers already sell on at least one other marketplace, up from 42% in 2024. Walmart is the most common next channel for FBA brands, mainly because Walmart's ranking algorithm weighs price and shipping speed differently than Amazon's, which can give well-priced, well-fulfilled products a faster path to visibility than they'd get fighting for placement on Amazon. Before going further, three terms worth defining if you're newer to this: FBA (Fulfillment by Amazon) is Amazon's pick-pack-ship service for sellers. WFS (Walmart Fulfillment Services) is Walmart's equivalent. [TACoS](https://sellerview.ai/blog/amazon-profit-calculator-tacos-vs-acos) (Total Advertising Cost of Sale) measures ad spend against total sales, not just ad-driven sales, and is generally a more honest read on profitability than [ACoS](https://sellerview.ai/blog/amazon-acos-explained) (Advertising Cost of Sale) alone, which only looks at ad-attributed sales. ## What Should Software for Amazon FBA Sellers on Walmart Actually Do? Once Walmart enters the picture, your software stack needs to do two distinct jobs, and most sellers only buy for the first one: ●      Job 1 - Get listed and stay in stock: publish products to Walmart, map attributes correctly, and keep inventory and pricing synced so you don't oversell on either channel. ●      Job 2 - Tell you if it's working: show real profit per SKU per channel, after WFS or FBA fees, ad spend, and returns, not just top-line sales. Almost every tool on the market solves Job 1. Very few solve Job 2, which is exactly where most sellers get burned three months into a Walmart launch. ## WFS vs FBA: The Fee Math You Need Before You Ship Inventory Walmart's fee structure looks simpler on paper - no monthly subscription fee, versus Amazon's $39.99/month Professional plan. But the fulfillment and storage line items matter just as much as the headline number: **Fee Type** **Amazon FBA** **Walmart WFS** **Monthly / subscription fee** $39.99/month (Professional selling plan) $0 - no signup or subscription fee **Referral fee** Varies by category - check current Seller Central fee schedule 6% to 15% of item price, by category **Fulfillment fee** Varies by size tier - check current FBA fee schedule Starts at $3.45/unit (standard); up to ~$9.50/unit for large sizes **Storage fee** Varies by month and season - check current FBA fee schedule $0.75/cu ft/month (Jan-Sep); $1.20-$1.50/cu ft/month (peak Oct-Dec) **Long-term storage penalty** Applies after 365 days in an FBA warehouse Escalates up to $7.50/cu ft/month after 450 days (effective June 30, 2026) Two things worth flagging. First, Walmart's long-term storage penalty gets steep: inventory sitting past 450 days can be charged up to $7.50 per cubic foot per month under the tiered structure effective June 30, 2026, so slow-moving SKUs are not a place to test Walmart. Second, Amazon's exact referral, fulfillment, and storage fees vary by category and size tier and change periodically, so always check your current Seller Central fee schedule before you model margin - don't rely on a number from an old blog post, including this one. ## Comparing the Tools Here's how the main options stack up if you're an Amazon FBA seller adding Walmart. Sellerview.ai isn't a direct alternative to the others below - it's not a listing or inventory-sync tool. It's the profit layer that sits on top of whichever sync tool you pick. **Tool** **Key Feature(s)** **Pricing** **Free Trial** **Best For** [**Sellbrite**](https://www.sellbrite.com/) Multichannel listing + inventory sync across Amazon, Walmart, eBay, Etsy, Shopify Free plan (under 30 orders/mo); paid plans $29-$179/mo Yes Sellers who want listings live on Walmart fast without heavy setup [**CedCommerce**](https://cedcommerce.com/) Marketplace-specific connector apps, attribute mapping, bulk catalog push to Walmart, Amazon, eBay, TikTok Shop Per-integration, roughly $20-$50/mo per channel app Yes (7-day, common) Shopify/Magento sellers who need channel-specific connectors [**Linnworks**](https://www.linnworks.com/) High-volume inventory control, order routing, warehouse management across channels Contact vendor Contact vendor High-SKU-count sellers needing heavy operational automation [**ChannelAdvisor**](https://login.channeladvisor.com/) **(Rithum)** Enterprise catalog sync, marketplace compliance, ad management at scale Contact vendor Contact vendor Large catalogs and enterprise multichannel operations [**Sellerview.ai**](https://sellerview.ai/) SKU-level profit and loss across every channel you sell on, not just listing sync $15/month Yes Sellers who need to know if Walmart is actually profitable, not just live For pure listing and inventory sync, Sellbrite is the fastest to set up if you're running a lean catalog, while CedCommerce fits Shopify and Magento sellers who want channel-specific connector apps. Linnworks and ChannelAdvisor (now part of Rithum) are built for higher SKU counts and enterprise operations, with quote-based pricing to match. None of the four are built to answer the profit question - which is a separate layer entirely.

Here's the harsh truth: a green checkmark on your Walmart dashboard means the listing is live and the order shipped. It says nothing about whether that order made you money once the WFS fulfillment fee, storage fee, referral fee, any Walmart Connect ad spend, and your COGS are all subtracted. This is exactly what Sellerview.ai tracks automatically - SKU-level profit and loss, and TACoS vs ACoS clarity, across every channel you sell on, not just Amazon. Instead of checking four dashboards and doing the subtraction yourself in a spreadsheet, you see, SKU by SKU, whether Walmart is adding real margin or just adding revenue. ## How to Expand to Walmart Without Losing Money ●      Start with your top 20-30 SKUs by net margin, not by revenue. Your best Amazon seller by units isn't automatically your best Walmart candidate - our [SKU-level scale investment breakdown](https://sellerview.ai/blog/amazon-calculator-sku-scale-investment) walks through how to rank SKUs by margin before you scale into a new channel. ●      Model landed cost on WFS before you list: referral fee + fulfillment fee + storage fee, using the fee table above as a starting framework, not a final number. ●      Ship a small WFS test batch first, or start self-fulfilled, instead of pushing your entire catalog to Walmart in week one. ●      Track true profit per channel weekly, not just a combined sales dashboard - channel-level blending hides which one is actually carrying the business. ●      Expect to re-price for Walmart's algorithm. Price and shipping speed carry more ranking weight there than they do on Amazon - see our [Amazon marketing strategy guide](https://sellerview.ai/blog/amazon-marketing-strategy) for how pricing signals affect ranking across channels. ## The Bottom Line Software for Amazon FBA sellers expanding to Walmart needs to do more than get you listed. Pick a sync tool that matches your catalog size and platform, model WFS fees before you ship inventory, and put something in place that shows you real profit per SKU per channel - not just sales. That last piece is the one most sellers skip, and it's the one that decides whether Walmart becomes a second profitable channel or just a second place to lose money.

At minimum, a listing and inventory sync tool (like Sellbrite or CedCommerce) to get products live on Walmart without overselling. On top of that, a profit-tracking tool that shows SKU-level margin after WFS fees is what tells you if the expansion is actually working. ### Is Walmart Fulfillment Services cheaper than Amazon FBA? It depends on your product size and category. WFS has no monthly subscription fee, while Amazon charges $39.99/month for a Professional plan. But WFS fulfillment and storage fees, and Amazon's referral and fulfillment fees, both vary by category and size tier, so you need to run your specific SKUs through both fee schedules rather than assume one is universally cheaper. ### Can I use the same listings software for Amazon and Walmart? Yes. Tools like Sellbrite, CedCommerce, and Linnworks are built to sync listings, inventory, and orders across both marketplaces (and others) from one dashboard, which is the main reason sellers adopt them before expanding channels. ### How do I know if my Walmart sales are actually profitable? You need SKU-level profit and loss that accounts for WFS or self-fulfillment costs, referral fees, ad spend, and returns, separated by channel. This is the exact gap Sellerview.ai is built to close, since most listing and sync tools stop once the order ships and don't calculate what's left after costs. ### How many sellers are on Walmart Marketplace in 2026? Walmart Marketplace crossed 200,000 active sellers in mid-2025, up from about 160,000 in 2024, and has continued to add sellers at a fast pace into 2026 according to Marketplace Pulse tracking data. ## Sources 1\.
