If you’re exploring marketplaces and weighing your first (or next) channel, you’re probably asking: should I start with Amazon, add Walmart, or run both? Each platform has its own rules, fees, fulfillment options, and shopper expectations, so the “best” fit depends on your products, margins, and how you operate.
What works on one doesn’t necessarily work on the other, and you may be surprised by which one ends up being more suitable for your business plans. Let’s break down how selling on both platforms works so you can decide whether to launch on one, the other, or both.
Overview: Amazon Marketplace at a Glance
Amazon is the largest e-commerce marketplace, known for massive demand, Prime-driven conversion, and a mature toolset for branding, fulfillment, and advertising. It serves virtually every selling model from private label to wholesale and handmade, making it the default launchpad for many sellers. Think of Amazon as the scale engine: huge traffic, powerful levers, and intense competition.
Key strengths of Amazon include:
- Traffic and Conversion: Enormous shopper base with Prime expectations that lift conversion when you’re FBA/Prime-eligible.
- Fulfillment by Amazon (FBA): Nationwide 1 to 2 day delivery, built-in customer service and returns, and Prime badges that boost buy-box odds
- Brand Toolkit: Brand Registry, A+ Content, Stores, Posts, Vine, and brand analytics for deeper storytelling and insights.
- Advertising Powerhouse: Sponsored Products/Brands/Display, retargeting, and granular controls for placements, bidding, and search term mining.
- Ecosystem and Integrations: Mature third-party apps for SEO, pricing, ops, analytics, and automation.
Pros
- Unmatched demand and discoverability potential
- Strong fulfillment reach via FBA
- Robust branding and ad levers for scale
- Deep ecosystem of tools, talent, and education
Cons
- High competition and rising CPCs
- Complex, evolving policies and strict enforcement
- Fee stack can compress margins
- Success often requires constant optimization and capital for inventory/ads
Overview: Walmart Marketplace at a Glance
Walmart Marketplace is a curated, fast-growing channel with value-oriented shoppers and lighter competition in many categories. It mirrors much of the Amazon playbook (fast shipping, marketplace ads) while staying simpler on fees.
Key strengths of Walmart include:
- Selective Seller Base: Lower saturation can mean easier visibility for well-positioned SKUs.
- Walmart Fulfillment Services (WFS): WFS has TwoDay/ThreeDay badges, Walmart-handled customer service and returns, and competitive economics that are often favorable for bulky SKUs).
- Cost Simplicity: No monthly seller subscription; straightforward referral fees and optional WFS fees.
- Omnichannel Trust: Walmart’s offline brand equity carries online; value messaging and clear pricing resonate.
- Advertising with Cheaper Clicks: Walmart Connect is simpler, often with lower CPCs.
Pros
- Lower competition in many niches; easier path to page one
- Fast-ship badges via WFS can meaningfully lift conversion
- Cleaner fixed-cost profile
- Strong fit for value-priced essentials and practical categories
Cons
- Application approval is selective; ramp can be slower
- Lower overall traffic than Amazon
- Younger ad and brand toolset
- Operational nuances like attributes and pricing parity require a tailored approach
Side-By-Side Feature Comparison
Now that you know more about these two platforms, how do their functionalities and processes compare? Let’s compare the core areas for selling on Amazon vs. Walmart.
Getting In: Application vs. Sign-Up
Before you worry about listings and ads, you’ve got to get through the front door.
- Amazon: Amazon is famously easy to join. That’s useful when you’re starting out, but it also means there are many sellers in almost every niche. You win by being sharp on product, price, shipping speed, reviews, and advertising.
- Walmart: Walmart is selective. They care about your professional history, performance metrics, and whether your assortment and pricing make sense for their customers. If you already perform well on Amazon, that helps your case.
When applying, highlight your operational reliability through details like on-time ship rates and defect rates, assortment quality, and fulfillment capability (e.g., you’re ready for WFS or can meet 2-day SLAs).
Cost Reality Check
Margins live and die by fees, and the two marketplaces take their cut in different ways. These are the typical fee stacks for each so you can see where profits are made or lost:
- Amazon: Referral fees vary by category, then FBA fees stack on top for picking, packing, storage, and surcharges. There’s a monthly fee if you have a Pro account, and sellers should also consider ad spend in their Amazon fees as they’re a must for visibility in competitive niches.
- Walmart: There’s no monthly subscription fee, but there are referral fees by category. There are WFS fees similar to Amazon’s FBA fees for storage and fulfillment. Walmart Connect ads are optional but increasingly useful, and often cheaper per click compared to Amazon ads.
If your margins are tight, Walmart can feel a little friendlier. But the real savings come from smart fulfillment and tuned ads, not just the fee table.
Fulfillment Face-Off
Fast shipping and reliable service are a must for both platforms, but the mechanics aren’t identical. Amazon’s FBA is the veteran; Walmart’s WFS is the fast-improving challenger.
- Amazon: FBA typically offers fast delivery and trusted returns, so it’s a big reason customers love Amazon. For you, it lowers the operational load but can get pricey, especially with oversized items or slow movers that rack up storage fees.
- Walmart: WFS offers similar perks as FBA. While Walmart’s network isn’t as large as Amazon’s, it’s grown fast and works well for many categories.
Traffic and Intent
Traffic volume is just one part of the puzzle. Let’s compare that, as well as the challenges of winning that traffic between both platforms:
- Amazon: Amazon typically has tons of demand, but getting noticed requires great SEO, strong offers, and usually paid traffic. You can scale fast, but it’s expensive to defend your turf.
- Walmart: Traffic is lighter, but competition is lower. If you come in with strong pricing, decent content, and fast shipping, it’s often easier to land on page one than it is on Amazon. The shoppers skew value-conscious, and they respond well to clear pricing and fast delivery badges.
Advertising: Pay-to-Play vs Pay-to-Learn
Ads work differently on each marketplace, and that shapes how you launch, scale, and protect margins. Here’s how to think about each platform:
- Amazon Ads: Sponsored Products and Sponsored Brands can be the difference between page one and page none. But CPCs are competitive, and you’ll need tight keyword management, negatives, and bid control to protect margins.
- Walmart Connect: Walmart’s ad platform is simpler but effective. Sponsored products and search boost visibility, often at lower CPCs than Amazon. This makes it perfect for testing new SKUs, harvesting keywords, and building rank before competition catches up.
Reviews and Social Proof
On Amazon, reviews are the oxygen of conversion: critical but slow and tightly regulated. On Walmart, many categories have a lower review baseline, so you can look credible with fewer but solid ratings. Because the bar is lower on Walmart, a small stream of genuine, recent reviews can move the needle faster versus Amazon’s “hundreds-plus” norm in crowded niches.
Proactive review management is a must on both platforms for protecting your brand reputation, identifying pain points, and removing irrelevant or fake reviews. You can run your listings through specialized review checking tools that help spot and report suspicious reviews. Weeding these out allows genuine feedback to shine and guide potential buyers.
While getting lots of reviews is important on Walmart and Amazon, aim for quality over volume. Fast, helpful customer service and crystal-clear product content reduce returns and earn better reviews on both platforms. Keep things clean by following each marketplace’s policies and growing ratings through approved programs and great post-purchase experiences.
Listing Optimization
Strong content drives clicks and conversions on both marketplaces, but the formatting and emphasis aren’t identical. Here’s how to approach each:
Amazon (What carries over):
- High-quality images: Fill all slots: clean hero image on a white background, angles, lifestyle, and one simple infographic.
- Clear, keyword-led titles: Front-load primary search terms customers actually type.
- Benefit-first bullets: Lead with outcomes, then back up with specs.
- Scannable descriptions: Address objections (fit, compatibility, care) to reduce returns.
Walmart (What needs to change):
- Shorter, stricter titles: Keep them concise and readable; no keyword stuffing.
- Attribute mapping matters more: Provide details like size, material, count, compatibility, and power filters whenever possible.
- Category taxonomy: Double-check product type and category; miscategorization quietly buries listings.
Pricing Strategy
Shoppers compare the total cost to their doorstep. Both platforms reward competitive landed price (a.k.a. the cost of an item plus shipping), but you’ll manage parity and fees a bit differently.
Amazon (Guard rails):
- Parity pressure: If your Amazon landed price is consistently higher than Walmart’s, expect visibility pressure.
- Fee reality: Fees for FBA, referrals, and ads can stack; some SKUs become margin-thin, especially bulky or slow movers.
Don’t force every SKU through FBA. Some items are better FBM or on Walmart first.
Walmart (Smart opportunities):
- No monthly seller fee: The cleaner fixed-cost profile makes testing safer.
- WFS economics can win: Depending on size, weight, and storage velocity, WFS may beat FBA math.
- Simple framework: Rank SKUs by contribution margin after fulfillment per marketplace; lead with the ones that look best on Walmart math, not just your Amazon heroes.
Remember: keep intentional parity. Undercutting yourself on one channel can tank the other’s Buy Box and rank.
Selling on Walmart vs. Amazon: Which Is Better?
When it comes to deciding which platform is “better” for your business, “better” depends on your products, margins, and how you operate.
When Walmart Is the Better Fit
Walmart shines when shoppers want strong value, fast shipping, and straightforward choices. If your catalog leans practical over premium and your logistics math favors WFS, you’ll often see cleaner margins and easier wins here. Consider Walmart first in these scenarios:
- Value-priced essentials with clear specs and stable demand
- Heavier or bulkier items where your Walmart/WFS fee math beats FBA
- Gaps on Walmart’s digital shelf, especially if they are hyper-crowded on Amazon
- Brick-and-mortar adjacency, as items that shoppers associate with the Walmart brand, like home, baby, and outdoor products often get healthy engagement online.
When Amazon Still Wins
Amazon is still the place to go big on brand, storytelling, and sheer search volume. If your products thrive on reviews, premium positioning, or complex merchandising options, Amazon’s ecosystem gives you more levers. Lean into Amazon in cases like these:
- Premium or niche products that rely on deep reviews, advanced A+ storytelling, and massive search volume.
- Categories where Prime is non-negotiable and you need Amazon’s reach to make the economics work.
- Bundles or complex variations that depend on Amazon’s mature catalog tools and Brand Store ecosystem.
Conclusion
If you’re choosing where to start selling, Walmart and Amazon are two compelling options. Amazon can be a high-volume engine, but Walmart is a margin-friendly channel for testing the waters. Depending on your business, you can pick one or even pick both to make your brand less dependent on any single algorithm.
The real win is fit. Match each SKU to the channel where the fee math, fulfillment, and shopper intent line up best. Lean on Amazon when you need scale and advanced branding; lean on Walmart when you want lighter competition and value-driven shoppers.
