Selling on eBay vs Amazon: Which Suits What

The comparison is usually framed as which marketplace is bigger, which is the least useful question available. They work differently enough that plenty of products do well on one and badly on the other.

The difference that matters is control. On eBay the seller owns the listing. On Amazon the catalogue owns the listing and the seller has an offer on it.

Neither is better in general; each is better for different products. Amazon suits new, branded, standardised products with a barcode and steady demand, where shoppers know what they want and choose on price and delivery. eBay suits used, refurbished and mixed condition stock, parts with fitment data, collectables and anything that needs explaining, where the seller owns the listing and buyers watch and make offers.

Most established sellers use both, with one stock plan and different listings, prices and fulfilment for each, because the two work differently even when the product is the same.

On Amazon, one product has one detail page, and every seller of that product competes for the buy box on it. The page's images and copy are the catalogue's rather than yours, which is why brand registry matters so much there.

On eBay, your listing is yours. Your photographs, your description, your terms. Two sellers of the same item have two listings competing in search rather than two offers competing on one page.

That single difference explains most of the others.

eBay suits used and refurbished goods, parts and spares, anything where condition varies, collectables, and products that need explaining. Fitment data on parts is a genuine competitive moat, and eBay's is better than Amazon's.

Amazon suits new, branded, standardised products with strong demand and a clear identifier, where the buyer knows what they want and the decision is price and delivery.

A brand with a new product and a barcode should usually be on Amazon first. A seller with mixed condition stock, or with items no catalogue has a page for, will find eBay much less hostile.

Pricing works differently on the two marketplaces because the listings work differently, and a pricing habit carried from one to the other usually loses money on the second.

On Amazon, the offer competes on one page. Every seller of a product competes for the Featured Offer, and price is one of the main things that decides it, alongside delivery speed and seller performance. A small price difference can move most of the sales to another seller, which is why repricing exists, and why it needs a floor.

On eBay, the listing competes in search. Two sellers of the same item have two listings, and a buyer can see both, compare the photographs, the condition and the terms, and choose the dearer one for a better description or faster postage. Price matters, but it does not decide the whole sale on its own.

eBay lets buyers negotiate. Best Offer lets a buyer propose a price, and a seller can set offers to be accepted or declined automatically above or below chosen amounts. Sellers can also send offers to buyers watching a listing. Amazon has no equivalent.

Auctions still have a place. For rare, collectable or hard to value items, an eBay auction lets the market set the price. For anything with a known value, a fixed price with Best Offer usually serves better.

Promotions differ. Amazon's coupons and deals carry fees and price history rules. eBay's sale events and markdowns are set by the seller on its own listings.

Set the price for each marketplace on its own terms, from the margin after that marketplace's fees, rather than one price copied across.

Amazon buyers are shopping. eBay buyers are frequently hunting: comparing, watching, and willing to make an offer.

Watchers and offers are real mechanics on eBay and have no equivalent on Amazon. A listing with watchers is a listing with an audience you can act on with a promotion, which is a lever Amazon does not give a seller.

eBay's final value fee is charged on the total including postage, with category variation. Amazon charges a referral fee on the same basis, plus fulfilment where FBA is used.

Fulfilment is where the structural difference lies. Most eBay sellers fulfil themselves, so postage and handling are the costs to manage rather than a band table, and delivery speed is a competitive lever you control rather than a service you buy.

Both reward sales velocity and conversion. eBay adds seller performance and service metrics to the calculation in a way Amazon largely does not, which means the way you run the account affects the visibility of every listing on it.

That is why top rated status is worth pursuing rather than being a badge, and why feedback management is an operational discipline rather than customer service. Both are covered in top rated seller requirements and handling negative feedback.

Both marketplaces sell advertising inside their search results, and the two models charge in different ways, which changes how a seller should judge them.

Amazon charges for clicks. Sponsored Products and the other Amazon ad types mostly charge when a shopper clicks, whether or not they buy. The seller pays for attention and has to make the listing convert it, which is why conversion and advertising efficiency are so closely linked on Amazon.

eBay offers two models. One charges a percentage of the sale price only when a promoted listing sells after a click on the promotion, so the seller pays for sales rather than attention. The other charges per click, like Amazon, for more prominent placements. Many eBay sellers start with the first, because the cost only arises when a sale does.

Judge both against margin. A percentage rate on eBay is a fee on the sale, and it has to fit inside the margin after the final value fee and postage. A cost per click on Amazon has to be divided by the conversion rate to see what each sale costs. Either way, the advertising cost per sale is the number to compare with what each sale earns.

Account standing matters more on eBay. Because eBay's search weighs seller performance, a promoted listing on an account with poor service metrics fights its own account. Fixing dispatch and tracking can do more for visibility than raising an ad rate.

Budget each on its own. The two channels respond differently through the year, so a single advertising budget split by habit rarely serves both. Fourth quarter advertising budgets across marketplaces covers how to split it.

Amazon's returns policy is Amazon's, applied to your orders whether you agree with it or not. On eBay the seller sets the return window and who pays the postage, within the marketplace's minimums.

That is real control and it is a real trap. Free thirty day returns improve visibility and conversion, and they also invite them, so the setting has to be priced rather than copied from whichever competitor is winning.

The pattern worth watching is returns concentrated in one product, which is a listing problem rather than a policy one. The description promised something the item is not, and the cheapest fix is on the page.

Take a seller with a stock of used camera lenses in varying condition.

On eBay each lens gets its own listing: its own photographs of the actual glass and barrel, a description of every mark, the mount and compatibility stated, and Best Offer switched on. A buyer can see exactly what they are getting, ask a question before buying and make an offer, and watchers on a slow listing can be sent a discount. The condition is the selling point, so the listing carries it.

On Amazon the same lens is an offer on the existing product page, under one of Amazon's used condition grades, with a condition note in place of photographs of the item. The buyer chooses mainly on price, condition grade and delivery, and the lens with a small mark competes on the same page as one without.

So the better lenses, where the condition note does the work, can sell well on Amazon, and the ones whose value depends on showing exactly what they are belong on eBay. The stock is one pool, and each unit goes where it fetches most after fees.

Most established sellers do, and the mistake is running them the same way. The listing copy, the pricing strategy and the fulfilment model should differ, because the mechanics differ.

The inventory plan should be shared, because stock is stock. A unit committed to one marketplace is a unit the other cannot sell, and the allocation should follow margin after fees rather than habit.

From Amazon to eBay. 1. Choose the products that suit eBay rather than the whole catalogue: used and returned stock, parts, items that need explaining. 2. Write eBay listings for them rather than importing Amazon's copy, with your own photographs and item specifics filled in, since eBay's search reads both. 3. Set the returns window and postage deliberately, as above. 4. Connect the stock so a unit sold on one is withdrawn from the other at once, before the first order arrives.

From eBay to Amazon. 1. Check that each product has a barcode and an existing product page, or the right to create one. 2. Check whether the brand or category needs approval for your account. 3. Decide fulfilment, your own or fulfilment by Amazon, against Amazon's delivery expectations. 4. Plan for reviews to start from nothing, since eBay feedback belongs to your eBay account and does not carry across. 5. Share the stock plan in the same way, so neither channel sells what the other already has.

A seller on both marketplaces usually knows which one sells more. Fewer know which one earns more for each product, and that is the figure that should decide where stock and effort go.

Contribution per unit, per marketplace. For each product, the sale price less the marketplace's fees, the fulfilment or postage, the advertising per unit and the cost of returns. The same product often earns noticeably more on one than the other.

Sell-through. How quickly stock sells on each. A product that earns more per unit on eBay but sells a third as fast may still belong on Amazon, where the stock turns into cash sooner.

Returns and cases. Return rates and their reasons on each marketplace. A product returned far more often on one may be described better on the other, or may attract a different kind of buyer there.

Time. The hours each marketplace takes to run: listing, messages, returns, disputes. eBay's one listing per item can take more time per unit for used stock; Amazon's catalogue can take more time when listings are contested. Time is a cost even when nobody invoices it.

One table, read monthly. Each product, each marketplace, the four measures above. The table shows which products to move, which to withdraw from one marketplace, and where the next listing effort should go.

The answer is rarely one marketplace for everything. It is usually a split by product, which is what the comparison is for.

We run both, so the answer to which channel deserves a given product is one answer rather than two opinions: eBay account management and Amazon account management under one plan.

For brands adding a third, Walmart behaves differently again, and a direct store trades marketplace fees for the cost of buying the traffic.

If the question is which of these deserves the next quarter's attention, that is the conversation to have.
