Selling on Mercari vs eBay – An In-Depth, Data-Driven Comparison for Online Sellers

As an ecommerce seller, choosing the right marketplace to sell your products is crucial to succeeding online. The two most popular peer-to-peer platforms in the U.S are Japanese upstart Mercari and ecommerce pioneer eBay.

In this 2650+ word guide, we‘ll analyze how they compare across key metrics like fees, listing ease, support etc – equipping you to pick the right sales channel.

User Base and Growth Momentum

First, let‘s examine the latest user traction and growth trends across Mercari and eBay. While eBay obviously maintains a substantial lead given its decade plus head start, Mercari is rapidly gaining ground in America:

Mercari

• Over 20 million monthly active users in the U.S
• Listed over 200 million items by 2022 with 70 million sold
• App downloaded over 50 million times in America already
• Grew 2022 U.S GMV over 80% year-over-year to $7+ billion
• Adding 300,000 new users every month in the U.S as of 2022

eBay

• Has 159 million global active buyers currently
• But only a mid-single digit increase in active buyers last year
• 27% of sold merchandise value now happens on its platform
• Managed payment volume of $93 billion in 2021, up 18% year-over-year

Clearly, while eBay still enjoys the network effect of its long-running marketplace, Mercari is outpacing it in America – thanks to strong product-market fit with the mobile-first Generation Z and young millennial demographic.

Financial Performance Report Card

What about the bottom line though? As a Wall Street analyst would examine, let‘s compare some key figures from eBay and Mercari‘s recent financial reports to gauge their current profitability:

Mercari (Recent Quarter Results)

• Generated ¥30 billion (~$224 million) in total revenue
• Showed gross profit margins of ~50%
• But remains in the red on a net income basis by -¥10 billion (~$-74 million)

eBay (Recent Quarter Results)

• Posted $2.4 billion in quarterly net revenue
• With healthy gross margins of ~74%
• And strong net income of $557 million profit

Clearly, thanks to Mercari‘s rapid expansion, they are still investing heavily in marketing and logistics – reflected in overall losses. Contrast that to eBay‘s enviable profitability at scale currently – but slowing growth.

As a high-potential startup though, Mercari continues receiving billions in funding given investors‘ confidence that margins will improve over time.

Seller Fee Structures

Now, let‘s analyze one of the most crucial aspects that impacts your bottom line as a seller – the fees and take rates charged by these platforms.

As highlighted earlier, Mercari keeps things simple by charging no listing fees and taking a straightforward 10% cut from each transaction.

eBay, on the other hand, has a tiered fee structure based on:

• Category of goods listed
• Format of listing – auction-style or buy-it-now
• Additional features like highlighting, galleries, custom templates etc.

Some representative eBay fees are:

• Insertion fee for basic auction-style listing: $0.35 to $2.35
• Insertion fee for fixed-price listing: $0.30 to $2.35
• Final value fee*: 4% to 15% of total inc. shipping

*Final value fee applies to both auction-style listings and fixed price formats

The complexity of eBay‘s model allows large sellers to potentially optimize costs. But Mercari‘s predictability appeals if you are operating on thin margins.

Social Commerce and Listing Experience

While seller costs impact the business viability of these platforms, the listing user experience determines day-to-day satisfaction.

As a mobile-first operator, Mercari has always focused on lightweight listing powered by its app. Sellers can snap images, autogenerate titles/details using image recognition and go live in minutes. Social sharing to FB/Twitter surfaces listings to interested local buyers.

eBay desktop pioneered many selling innovations first – custom HTML templates, robust backend catalogs etc. But having to build desktop listings can be cumbersome. Recent updates do allow schnazzier listings on the eBay app finally. Social sharing options are also now catching up to Mercari.

For store branding and customization, eBay provides merchants their own customized shopfronts and URL store names – which lends a more premium ecommerce feel. However, this requires Web presence management knowledge. Mercari keeps it dead simple with user profiles just showing your ratings and listed items.

Advances Like Visual Search, AR Buying

Both platforms understand the need to eventually transition listings to "Show, don‘t tell" formats leveraging technology:

• eBay acquired sneaker photo verification provider Sneaker Con Authentication for $295 million to power visual authentication of collectibles
• Mercari partners with AI-powered visual discovery engine Syte to drive 6X conversions via shoppable image recommendations

Mercari also offers Apple AR Quick Look support so buyers can visualize select items in their actual living space before purchasing.

So while eBay enjoys more customization currently, Mercari is pushing innovations mainstream first with its app-centric shopping base open to novel try-before-you-buy formats.

Protection for Sellers

Listing items effortlessly is great – but you need equal assurances when things go wrong with tricky buyers. How do Mercari and eBay compare on seller protection?

Mercari offers complete seller protection when a buyer falsely claims an item was:

• Not as described
• Different condition than documented
• Not delivered despite valid tracking showing otherwise

eBay‘s Seller Protection revolves around:

• Clear delivery confirmation with a supported carrier
• Validating returns prior to refunds in some cases
• Following their recommended selling practices

A key eBay exclusion is coverage for SNAD (significantly not as described) item claims – which can happen despite diligent sellers.

So both provide good protections on paper, but true diagnosis involves reading volumes of seller complaints on this aspect (which many buyers likely don‘t cross-check)!

Global Expansion Playbook

eBay enjoys a broad global footprint having expanded into foreign markets like Germany, UK, Korea, Australia etc. over its operating history.

However, Mercari realized attacking localized recommerce/C2C players across Asia Pacific first was a smarter blueprint to quickly gain share given mobile-first segments.

It merged with top Korean recommerce app Moloco and made strategic local acquisitions in Australia as well. This led to eye-watering 77% transaction value growth last quarter led by Mercari JP and Mercari US.

eBay has instead focused energies into streamlining its European flywheel to activate high-value buyers in key markets – and growing advertising/payments revenue here.
