Three browser tabs. One product. A budget that only stretches so far.

After Amazon, there’s a monthly cost plus a percentage of each sale. Walmart wants to see an app first. Shopify will require a credit card and eventually a serious marketing plan. So, where do you assign your efforts and investments? This comparison of fees, traffic, control, and daily demands is designed to point you to the right ecommerce platform for your brand, now. Or, in many cases, the best blend. And we should explain the blend, too.

The Quick Answer: Which Platform Fits Which Brand

Amazon if you want buyers fast. Walmart Marketplace if you want a second marketplace with no monthly fee and fewer rivals per product, especially in home and general merchandise. Shopify if you’d rather build a brand you own and keep more margin on each order.

That’s the shortcut, and shortcuts skip things. Your category, your ad budget, and the hours you can realistically give to operations can all change the answer. The details follow.

Amazon: Built-In Traffic, Built-In Competition

Over 60% of what’s sold on Amazon comes from third-party sellers, according to  Modern Retail’s reporting. Read that two ways. Buyers are already there. So is a crowd of sellers with products that look a lot like yours.

Amazon Pros

The biggest one is speed. Customers are not looking to browse Amazon’s immense product catalog; they are looking to purchase. A well-optimized Amazon listing with a few reviews under its belt will trend for units, even if it takes a few weeks to gain momentum. The additional Prime badge with FBA (Fulfillment by Amazon) often is the determining factor.

You also borrow trust. Buyers already know how Amazon returns, delivery, and payments work, so you don’t have to earn that confidence from scratch.

Amazon Cons

The fees have every step adding a layer, which will also be covered.

Prices are squeezed. Your listing is next to similar versions, and who holds the Buy Box generally goes to the cheapest with good credibility.

You don’t own the customer either. Amazon owns the relationship and the data, so there won’t be any email list for you at the end of a good quarter.

And pay risk is tangible. One claim flag or suspended listing can halt earnings cold, with appeals sluggish.

Amazon Fees at a Glance

The Professional plan is $39.99 a month. The Individual plan skips the subscription and charges $0.99 per item sold, which only makes sense at low volume (the break-even sits around 40 units a month). Referral fees, Amazon’s commission, run 15% in most categories, with a range of 8% to 45%. Confirm your category on       Amazon’s official seller pricing.

FBA fees sit on top of that. And since April 17, 2026, Amazon has added a 3.5% fuel and logistics surcharge to fulfillment fees, averaging about 17 cents a unit in the US. Amazon calls it temporary. Plenty of sellers aren’t convinced.

Run a quick example. A $30 product in a 15% category, with a $5.04 base fulfillment fee (the number Amazon used in its own surcharge example). Referral fee: $4.50. Fulfillment plus surcharge: about $5.22. Total: roughly $9.72, or 32% of the sale, and you haven’t paid for a single ad yet. Add sponsored products and returns, and Marketplace Pulse research (widely quoted in business press) has put Amazon’s total take near half of revenue for FBA sellers who advertise. Your numbers will vary, so run your own SKUs through Amazon’s revenue calculator before you commit.

Keeping listings, ads, and account health in shape is a job on its own. EcomVA’s Amazon account management support exists for exactly that grind.

Walmart Marketplace: Lower Fees, Real but Smaller Reach

Most comparisons treat Walmart like a footnote. That’s a mistake, and it can cost sellers money.

Walmart Pros

Start with what you don’t pay. No monthly subscription, no setup fee, no listing fee. Walmart’s own  pricing page says referral fees come out only when an order completes. For anyone testing a second channel, that’s a lot less risk to carry.

Referral rates are often lower than Amazon’s, though not everywhere, so check your category. Consumer electronics are 8%, major appliances 8%, personal computers 6%. Home, kitchen, and decor is 15%, which erases any advantage. Apparel is tiered by price: 5% on items of $15 or less, 10% from $15 to $20, 15% above that. Walmart has also run a new seller savings program in 2026 with discounts on early sales volume, so read the current terms and end date before you build it into your plan.

Your referral volume will generally be lower than Amazon, although not in all categories, so check your category. Consumer electronics 8%, major appliances 8%, personal computers 6%. Home, kitchen, and decor 15%, so more than negates the benefit. Apparel, tiered by price, 5% per sale up to $15, 10% from $15 – 20$, and 15% beyond that. Walmart has also been offering a new seller discount program in 2026 that gives discounts on early sales volume, so read the current terms and end date before you build it into your plan.

Competition is lighter too. Fewer sellers per listing means less of the race to the bottom you may know from Amazon.

Walmart Cons

Reach is the trade. Walmart.com pulls serious traffic, just not Amazon level, and the ramp-up can be slower in plenty of categories.

Then there’s the application. Approval isn’t a given. Expect to supply a US Business Tax ID (a Social Security number won’t do), a business address, personal ID, and verification documents. A track record on Amazon, eBay, or your own site helps your case. A brand new seller with no history may wait longer.

And it’s still a marketplace. Walmart owns the customer relationship, so the data problem from Amazon follows you here.

Who Walmart Fits Best

Established brands, mostly. Picture a kitchenware seller doing steady volume on Amazon while ad costs chew into margin. Moving the same catalog onto Walmart means a fresh pool of buyers and, in some categories, a lighter fee load. Not dramatic. Just smart. General merchandise, home, and everyday consumer goods tend to do best.

It is still real work, though. Seller Center has its own rules, feeds, and performance benchmarks. EcomVA has Walmart automation service packages that include catalog setup, listing management, and performance monitoring.

Shopify: Full Ownership, Zero Built-In Traffic

Think of Shopify as leasing a gorgeous storefront on a street with no foot traffic. Everything inside is yours. Getting people through the door is on you.

Shopify Pros

Control comes first. Shopify isn’t a marketplace. It’s software for running your own store on your own domain. Your brand, your design, your prices, your promotions, your customer list. Want to email a buyer from last spring, test a bundle, or rewrite your return policy? Go ahead. Nobody has to approve it.

There’s no per-sale commission, either. You pay for your plan and for payment processing. Basic costs $39 a month, or $29 a month billed annually, and Shopify Payments charges 2.9% plus 30 cents on online card sales. Use a third-party payment gateway instead, and Shopify adds 2% on Basic. Higher plans trim both numbers. Check  Shopify’s pricing before you decide, because plan names and prices moved this year.

Shopify Cons

No built-in traffic. Every visitor has to come from SEO, paid ads, email, social, or word of mouth. Time to first sale is longer for a brand new store. Honestly, longer than most owners expect.

Here’s the part most comparisons gloss over. Low platform fees aren’t the same as low cost. Processing a $30 order runs about $1.17, which feels tiny. But suppose you spend $12 in ads to win that customer. Now you’re at roughly $13.17, around 44% of the sale. On a first order, Shopify can cost as much as Amazon. It pays off when customers come back, and that’s why owning the list matters so much.

Add themes, apps, and someone who knows how to run the store, and the budget grows a little more.

Who Shopify Fits Best

Patient brands. If you want equity in your own storefront and email list instead of renting visibility, this is where you build it. It also suits brands with a strong story or a loyal niche, where price isn’t the only selling point.

Store setup, uploads, and app maintenance eat hours. EcomVA’s  Shopify virtual assistant service takes the recurring store tasks off your plate.

Amazon vs. Walmart vs. Shopify at a Glance

How to Decide Between Amazon, Walmart, and Shopify

Choosing the best ecommerce platform has less to do with rankings and more to do with fit. Pick the scenario below that sounds most like you.

If You’re Launching Your First Product

Go with Amazon. You’ll see what buyers actually buy, get real sales data, and collect reviews faster than you can get a domain. Just be sure to account for FBA and paid advertising expenses upfront so the profit line doesn’t blindside you by month three. If possible, buy a domain and start capturing emails in your off time.

If You Already Sell on Amazon and Want to Diversify

First Walmart, second Shopify. Walmart uses most of the catalog work you’ve already done, and the fee structures may be more favorable in your category. Shopify calls for a different kind of marketing muscle, so hold off until you’ve got operations humming. Launching both platforms simultaneously is an efficient way to burn out.

If You Want to Build a Long-Term, Ownable Brand

Use Shopify as a home base. Approach Amazon and Walmart as sources for new customer acquisition and then build repeat business through your proprietary (own website) brand search, social, and email marketing. One word of caution: Amazon does block off seller-directed traffic off Amazon, so review each marketplace’s policies should you choose to drive elsewhere.

If Budget for Marketing Is Limited

Use a marketplace. Between Amazon and Walmart, they will bring customers to your store, so you are not paying for each visit. Walmart, with no monthly fee, is the easiest entry if you’re qualified. A Shopify store with no traffic plan? That’s a costly digital brochure.

Why Most Successful Brands Don’t Pick Just One

Watch the evolution of seller behavior and the “which one?” The question diminishes. A product feed provider summarized DHL’s 2025 ecommerce report and found “if you sell to more than one marketplace, 63% do so on at least three”. Mirakl completed its 2026 seller report and found sellers who only sell to one marketplace averaged approximately $575k GMV, vs. those that sell to two or more marketplaces, approximating $10mm.

Salt that second number a little. With a vendor that profits from multiselling anyway, it’s just as natural that bigger sellers will be present in more channels. Shows correlation but no causation, but impossible to ignore the direction

The normal pattern: marketplaces for discovery and volume, Shopify for margin, brand equity, and the direct customer relationship.

Here’s the trap, and it’s a huge one. Own more channels and not only do you have more reach, but you also have more work. Inventory needs to be in sync everywhere. Listings slip up. Customer messages hit three inboxes. Each channel has its own requirements, and a stockout in one quietly damages another. That’s the operational drag customers are paying for.

Managing Multiple Platforms Without Multiplying Your Workload

Picture an ordinary week. You update a few listings, reconcile orders, answer customer messages, fix a suppressed ASIN, respond to a Walmart performance alert, and check ad spend. Fine on one channel. By the third, something slips.

At that point, multichannel ecommerce management turns into a staffing question more than a software one. Sync tools handle stock counts. They won’t draft a policy appeal or notice that a listing quietly lost the Buy Box.

A specialized Amazon Virtual Assistant handles listing improvements, inventory audits, ad reporting, and account health. A Shopify VA is less likely to know about uploading products, the flow of order management, and the maintenance of Apps. On the platform management side, a Walmart specialist understands Seller Center and their performance requirements. Platform knowledge is essential, because policies change frequently and an all-rounder usually finds out after the fact.

Do you always need one? No. One platform and a few dozen SKUs? You can probably wait. The day you add a second channel, though, start planning. EcomVA’s ecommerce virtual assistant hiring guide explains roles, costs, and what to hand off first.

Getting Started on Each Platform

Amazon. Open a Professional seller account, and see if your category needs approval. Nail the listing fundamentals: title, images, bullets, price. Decide early on FBA or self-ship. And if you want paid ads, get the listing converting organically before you spend a dime.

Walmart Marketplace. Make sure you collect all the required documentation before applying: Business Tax ID, W-9, business address, and personal ID. Once you apply, it will take a few weeks for the first sale. When you go live, get the Seller Center set up, select your fulfillment method, and make sure your item feeds are correct. 2. Get your performance standards from day one.

Shopify. Select a plan, select a simple theme, and turn on Shopify Payments (so you don’t pay a third-party fee). Then develop your launch traffic plan: a few SEO goals, a single paid channel, an email offer. Launching without one is the typical mistake in a Shopify launch.

Whatever you choose, decide early who’ll run the daily work. If the honest answer is “me, nights and weekends,” read our hiring guide for ecommerce virtual assistants before you’re underwater.

Conclusion

The top ecommerce platform in the abstract won’t find one. Only the best for your goal stage budget. Amazon invests the most in acquiring buyers. Walmart expands your market at often a lower cost. Shopify constructs the asset that is truly yours.

Begin with what fits your needs today. Then prepare for the load before adding the second channel, as that is when the load doubles and the errors begin to increase.
