At first glance, online marketplaces like Amazon and eBay seem to be a creation of mutual benefit. Ecommerce store owners gain increased exposure for their products, and the marketplaces gain an expanded product range without having to increase inventory.
On closer inspection, the mutual benefits remain, but the reality is more nuanced. Should you expand your presence beyond your online store and start selling your products on Amazon and eBay?
The answer is... it depends. A marketplace strategy may be a boon for some retailers and a bust for others. There are a lot of variables that need to be taken into consideration, including the type of products you sell, the intensity of competition in your category, marketplace fees and restrictions, and so on.
There are, however, some pros and cons that apply across the board. In this post, we’ll explore those pros and cons, so you can make the decision of whether or not to sell on marketplaces well-informed as to the upsides and the downsides.
Pros
1. Increased Sales
The chief draw of selling on marketplaces such as Amazon and eBay is the scale of their online presence. Amazon alone draws nearly 85 million unique monthly visitors - that’s a heck of a lot of eyeballs! And those eyeballs can translate into higher sales volumes. According to an Amazon executive, sellers report an average 50% increase in sales when they join Amazon Marketplace.2. Customer Acquisition
Nobody visits Amazon or eBay searching for your store. But they may be searching for - and discover - your products. Products they may not have discovered otherwise, or that they may have purchased from a competitor.Once you’ve got a customer in the door, even if it is through a marketplace, you’ve got a chance to win repeat business through excellent service and fulfillment. This is especially the case if you’re selling products in a category that encourages frequent, repeated purchases such as hobby supplies or fishing gear.
3. Marketplace Infrastructure
Marketplaces are all about strength in numbers. This is as true for online marketplaces as it is for real world examples like farmers’ markets, shopping malls, and food trailer parks. The variety and all-in-one aspect of the marketplace can draw in lots of customers who prefer that kind of shopping experience. Online marketplaces also bring the additional layer of single-stream checkout and fulfilment support in order to create a seamless experience for buyers.Cons
While there are some significant upsides to selling on marketplaces, there are also some drawbacks that need to be considered.1. Marketplace Fees
Setting up shop on a marketplace can potentially supercharge your sales, but it also exposes you to another cost center - marketplace fees. Most marketplace fees are deducted as a percentage of each sale, and can vary from site to site and even category to category. Before selling your products on a marketplace, you’ll want to make sure you have a good sense of your margins and a firm understanding of the marketplace’s fee structure. In highly commoditized, low-margin categories, the numbers may just not add up. See fees for selling on Amazon, and fees for selling on eBay.2. Marketplace Infrastructure
While the marketplace infrastructure has many advantages, it’s important to remember that it can cut both ways. Marketplaces don’t exist to help you, but to help themselves. They want the focus to be on the products, not the sellers. And that means they might restrict the degree to which you can brand your presence, communicate with customers, dictate what items you can and cannot sell, and so on.Additionally, there’s nothing to stop marketplace owners - in the case of Amazon, Sears, and so on - from “going to school” on third-party sellers, identifying popular products and stocking them themselves.
3. Keeping Inventory in Sync
A marketplace is essentially a second point of sale. And one that sometimes can’t be configured to talk to your shopping cart. In effect, both draw down the same inventory, but don’t sync with one another, making it challenging to understand your stock levels without lots of manual reconciliation. Fortunately, applications exist to help you aggregating orders from multiple sources and making sure your inventory stays in sync across all your stores.How to Choose a Marketplace
As you weigh the pros and cons of selling on a marketplace, it’s also worthwhile to consider which marketplace you would join. The tempting answer is “all of them!”, but each marketplace has its own system, its own processes and limitations and quirks. Learning to navigate those can take time you probably don’t have, so it’s best to stick to one or two marketplaces unless you know you can support more.Two of the largest and most well-known marketplaces are Amazon and eBay. Amazon’s Marketplace takes the sharper retail tack, and as a retailer itself Amazon provides tools to help third-party sellers become part of a seamless shopping experience, including “Fulfillment by Amazon”, which involves shipping your inventory in bulk to Amazon and letting them handle shipping.
eBay, on the other hand, is essentially a massive marketplace. Where Amazon focuses on the Amazon shopping experience, eBay offers seller tools and features that make it easier for you to feature your brand, as well as sell non-standard items.

Well-written and informative article. Mr. McDougall just made my decision about selling on Amazon easier!
Cuation about selling on Amazon : fees are placed in your account only every 14 days. So if you sell something you have to wait 14 days.
Then if you have offered chargeback or A to Z gurantees they keep your money for 30 or 90 days and if they close your account )as they did me for no reason) they make you wait 90 days even if you have positive feedback from buyers.
I will stick with ebay and getting my money quickly.
This is in response to Alex’s post. In regards to showing caution towards selling on Amazon, I would take more caution in using eBay and it’s evil step sister PayPal. Just the name makes me nauseous. As an experienced eBay seller with over 200 feedback (which doesn’t sound like a lot but it is when I was selling expensive items) I can tell you stay FAR away from PayPal and eBay. Many horror stories online, just do a quick Google search yourself. I’ve had eBay/PayPal (same company, which makes it horrible for customer support) actually take my money for 6 months. They deemed me a “high risk” account and shut me down literally for no reason. With just 3 to 4 disputes out of over 100 customers they used that as a reason to hold my money and close my account forever. I am no longer allowed to use PayPal for the rest of my life. Literally. They also held my money in a interest bearing account (where they earned the interest) for 6 months before releasing it. Lost my business and clients over this. Look if your selling something small out of your attic here and there then fine go ahead, but don’t try to start a business around eBay/PayPal. Bad idea. As far as Amazon holding my money..never had it happen. And the whole 14 days, that only applies if you have requested a money transfer within that 14 day period. In other words if you sell something on the 1st you can request your money the same day. But if you sell something on the 3rd you can’t request that money until the 14th.
So, If one was wanting to sell their hand carved wood items Ex.(housewares of all kinds, longbows,crossbows,made to order even) what, and where would you experienced gentlemen suggest?
To Lucas- Etsy.com Stay away from Ebay.
I’m an e-commerce newbie, thanks for the informative article!
Im a student and I have alot of books that i would like to sell. Im new at this and I would like to know where would be the best place to sell my books?
Very Informative,Thanks for the article.
Great article. Having sold items on both platforms for years, I would also add an additional pro to joining either eBay or Amazon’s Marketplace. A key factor in selling on either platform is that you know your marketing costs up front. Costs to market your products on a private web site, if not controlled, can easily grow to unexpected levels, and quickly. Although both eBay and Amazon do charge you a fee per sale, these are known costs that you can anticipate and bundle into your sales price.
Which one (amazon or ebay or another???) is the best place to sell old non-fiction books (like old issues of the Yale Review)? in terms of expected sales price and corresponding reasonable listing fees?
Thanks, in advance…. e-commerce newbie :-)
Amazon is good only if you have few items to sell.if you wish to sell in large quantity, there is all possibilities that your business will be closed by amazon seller performance without any reason just because some customers gave a negative feedback or filed A-Z claims. Amazon do not have a system to check the real reason behind the negative feedback and it will always side with Buyers. Amazon has a seller performance team sitting somewhere offshore and they will just close your business if your negative feedback or A-Z claims are more than 1% which will be outrageous, sometime as it will ruin your investment and hard work to establish. There is no system in Amazon to find out why a customer gave a negative feedback or filed a-z claim. There are buyers around who will just ORDER an item just to replace the same item which is out of order.They will return to us the defective item, keeping the good one you sold and claim for refund, if you argue with them they will file a-z claim or give negative feedback, to avoid that you will just refund them absorbing the loss. In many cases, buyers will give a negative feedback just because they are not in good mood or they expect more than what is offered for sale.There are many such instances happened to me. I have faced similar problem in ebay as well, but ebay will not close your business and they have a better policy to protect Sellers. They will not accept an A-Z claim,if sellers are not notified and gave sufficient opportunity for seller to resolve the issue.
i think that Andy guy is full of it… probably an amazon employee.. there is no doubt, ebay is much better and simpler then this amazon junk…
With ebay making major changes in fees, charging more from the sellers and putting a restriction on the minimum resolutions required to upload the product’s photo.. I believe the best would be to look for an alternative which is best in the competition and which allows you to keep all your earning to yourself and not share it. Where sellers can:
1. Create Free listings
2. No Transaction Fees
3. Auto sync with ebay..carry all your listings from ebay along with the ratings and feedbacks in just a click.
4. Free integration with Google products (which auto populates the product description form for you, saving your precious time) and Google Shopping (which tells anyone who search on google to buy a product that it is available on our website, which by the way we pay for and provide you the service absolutely free)
5. Payment option like Paypal and Amazon for the most secure transactions
6. which does not allow you to leave a feedback for a cancelled transaction
7. a platform that not only list your products but also organise your customers and market your product in your network
8. a platform where you are just not dependent on ratings but also can leverage your social and professional profiles using log in through facebook, linkedin or google accounts
9. A platform that allows you to know the counterparty and build trust on the basis of work profile, school, college and other such dimensions.
10.Unlike ebay it has just one website (not different website for every country) so you can sell products worldwide and buy awesome products from across the globe as well
11. Unlike Ebay you can upload any resolution image and do not need only high resolution images to upload
12. Last but not the least it is absolutely free
And so the website that gives you all this is www.truegether.com
We have released our beta version and the new website with all these points said above will be launched soon in June, 2013.
We request all the sellers to list their product and leave us a feedback to help us improve more and give you a splendid experience of selling online.
