The E-commerce Revolution: Why Online Selling Is Non-Negotiable

The past few years have accelerated an already unstoppable trend: the shift to digital retail. What was once a convenience is now a cornerstone of consumer behaviour. Whether it's the post-pandemic digital adoption by older generations or the continued dominance of online shopping among younger demographics, the message is clear: if you're not selling online, you're missing out on a colossal opportunity.

Think about it: 47% of global e-commerce sales flow through marketplaces. These aren't just websites; they're bustling digital cities where buyers and sellers connect. The numbers are staggering: between 2014 and 2021, the global online buyer count surged from 1.32 billion to an incredible 2.14 billion. E-commerce retail sales worldwide ballooned from $1.34 billion to $4.28 billion USD in the same period. This isn't just growth; it's a paradigm shift.

For your business, this translates into:

  • Expanded Reach: Access to customers far beyond your physical location.
  • Reduced Overhead: Often lower operational costs compared to brick-and-mortar stores.
  • Targeted Marketing: Powerful tools to reach your ideal customer.

The question isn't *if* you should sell online, but where.

Not all marketplaces are created equal. Some cater to specific regions, while others boast truly global footprints. When strategizing your e-commerce strategy, understanding this distinction is paramount. Let's look at the big players dominating the global online sales landscape:

The Global Marketplace Giants: A Snapshot

No. Marketplace Monthly Visits Sales Region
1 Amazon 5.2 billion Global
2 eBay 1.7 billion Global
3 Mercado Libre 683.9 million South America
4 Rakuten 575.8 million Japan
5 AliExpress 534.4 million Global (seller-focused Asia)
... ... ... ...
12 Allegro 190.2 million Poland

This table clearly shows a front-runner. Amazon leads by a significant margin, making it an undeniable force in global e-commerce marketplace. eBay, while global, lags far behind in traffic. Allegro, a powerful player in its local market, is notably absent from a truly international stage.

A Closer Look: Amazon vs. Allegro vs. eBay

Now, let’s dissect the three main contenders relevant to businesses looking to sell in Europe and beyond, focusing on what truly matters to a seller: ease of use, seller support, customer reach, and cost efficiency.

Amazon: The Undisputed Global Leader

Founded in 1994, Amazon isn't just a marketplace; it's an economic ecosystem. With 5.2 billion monthly visits, it’s not just ahead of the curve; it is the curve. Annual sales figures for Amazon are estimated at a staggering $442.4 billion USD, projected to hit $580 billion by 2023. Operating marketplaces in 18 countries, Amazon offers unparalleled access to diverse customer bases across continents.

Seamless Setup & Seller Support

Getting started on Amazon requires a thorough verification process, but once complete, you're ready to tap into a world of possibilities. Sellers can choose between an Individual plan (for under 40 items/month) or a Professional plan, catering to different scales of business. The seller dashboard is robust, offering tools for product listing creation, A/B testing, and comprehensive performance metrics. These metrics, tracking everything from defect rates to on-time delivery, give you granular control over your seller experience and customer satisfaction. Plus, Amazon’s extensive help resources and seller support are invaluable for both newcomers and seasoned veterans.

Unmatched Customer Reach & Loyalty

Amazon’s strength lies in its massive, highly engaged customer base. Globally, it’s the go-to platform. Programs like Amazon Prime, offering unlimited free deliveries and access to Prime Video for a small annual fee, cultivate incredible customer loyalty. Prime members are known to spend significantly more annually than non-members, making them a lucrative target audience for sellers. This widespread trust and habitual buying behaviour are major advantages for any business looking for consistent e-commerce growth.

Transparent Costs & Flexible Fulfillment

Amazon’s fee structure is transparent, with a monthly subscription for professional sellers and category-dependent referral fees. But where Amazon truly shines is in its fulfillment options. Sellers can choose:

  • Fulfillment by Amazon (FBA): This game-changer allows Amazon to handle storage, packaging, shipping, and customer service. It dramatically simplifies logistics, especially for cross-border e-commerce, ensuring fast, reliable delivery and peace of mind for sellers. Amazon takes responsibility for delivery times, which is a huge plus.
  • Fulfillment by Merchant (FBM): For those who prefer to manage their own warehousing and logistics, FBM offers flexibility, though it requires more hands-on effort.

eBay: A Global Auction House with Marketplace Features

As the second-largest global marketplace, eBay operates in 37 countries, attracting 1.7 billion visits monthly. While a significant platform, it presents a different selling dynamic. eBay is well-known for enabling sales of used items by individuals, blurring the lines between C2C and B2C transactions.

Formalities & Reach Limitations

A notable limitation for Polish sellers is that accounts must typically be registered on the Polish platform, potentially complicating direct international selling without advanced setup. eBay offers basic and advanced selling options, with the latter designed for international sales. Integration with PayPal for payments has been a long-standing feature, although eBay has introduced its own managed payments system recently.

Seller Panel & User Base

eBay provides a seller panel for managing listings, orders, and promotions. Its user base is global, but its traffic pales in comparison to Amazon. Critically, eBay lacks a direct equivalent to Amazon Prime, meaning sellers are often responsible for offering shipping incentives themselves.

Cost Structure & Fulfillment

eBay charges fees for listing items, a commission on sales (typically around 11% in most categories), and optional store subscription fees. Sellers on eBay are generally responsible for all aspects of fulfillment, including warehousing, packaging, shipping, and customer service. This can be a considerable logistical challenge for businesses aiming for high-volume or international sales.

Allegro: Poland's E-commerce Powerhouse

Allegro, established in 1999, is the undisputed leader of e-commerce in Poland. It’s deeply ingrained in the local consumer psyche, offering a familiar and trusted shopping experience. With 190.2 million monthly visits, it dominates the Polish market, with a Gross Merchandise Volume (GMV) of PLN 35.1 billion (approx. $8.65 billion USD) in 2020.

Local Focus & Seller Ease

Allegro offers both individual and business accounts, including Allegro Lokalnie for local selling. The platform provides tools for creating listing templates, promotional offers, and integration with local logistics partners like InPost. Its sales quality panel helps sellers monitor their performance, similar to Amazon's metrics.

Allegro Smart & Customer Loyalty

Allegro Smart is Allegro’s answer to Prime, offering free deliveries to parcel lockers and pickup points (for purchases over PLN 40) or by courier (for purchases over PLN 80) for an annual fee. This program has been hugely successful in fostering customer loyalty within Poland.

Costs & Emerging Fulfillment

Allegro charges listing fees, sales commissions (which vary by category and product price), and fees for maintaining inactive offers. Historically, sellers managed all fulfillment. However, Allegro is piloting "One Fulfillment by Allegro," a service akin to FBA, which is expected to expand soon. This could be a game-changer for sellers on the platform.

Strategic Comparisons: Where Should You Invest Your Resources?

Amazon vs. eBay: Global Reach with Distinct Approaches

While both are global, Amazon undeniably surpasses eBay in traffic, sales volume, and customer loyalty. The Amazon Prime program has cultivated a highly engaged and consistent buying habit among its members, who, on average, spend significantly more annually. Amazon's commitment to customer experience, streamlined logistics via FBA, and powerful Amazon Ads tools provide a more robust environment for serious sellers seeking scale and predictability. eBay, while still relevant, often serves a different niche, including auctions and peer-to-peer sales, and lacks the same level of integrated seller support and customer programs.

Amazon vs. Allegro: Local Champion vs. Global Titan

This is where the choice becomes more strategic. For businesses primarily focused on the Polish market, Allegro remains the dominant force. Its deep understanding of local consumer behaviour, coupled with programs like Allegro Smart, makes it an excellent choice for domestic sales. However, Allegro’s attempts at international expansion (like Allegro.de) have historically failed, reinforcing its position as a Polish-centric platform.

If your ambition extends beyond Poland, Amazon is the undisputed champion for international expansion. Its vast network of fulfillment centers, cross-border shipping capabilities, and unified seller accounts across multiple countries provide an unmatched platform for global selling. While Allegro is developing its fulfillment services, Amazon has perfected its model over decades, offering stability and scale that are hard to replicate. For long-term e-commerce growth and reaching a global audience, Amazon offers far greater potential.

Ultimately, the choice between Amazon and Allegro depends on your core business objectives:

  • If Poland is your sole focus, Allegro is a strong contender, leveraging local familiarity and loyalty.
  • If international markets, scalability, and robust fulfillment solutions are your priority, Amazon stands as the clear leader.

Making Your Move: Which Platform for Your Online Sales Strategy?

The decision of where to sell online – whether on Amazon, Allegro, or eBay – should be a strategic one, aligned with your business goals and growth aspirations.

While Allegro holds a firm grip on the Polish market and eBay offers a global presence with a different selling dynamic, Amazon consistently emerges as the most powerful and versatile platform for businesses aiming for substantial growth and international reach. Its unparalleled customer base, sophisticated seller tools, transparent cost structures, and industry-leading fulfillment services (FBA) create an environment ripe for success. Amazon isn't just a marketplace; it's a launchpad for global brands.

For businesses looking to optimize their marketplace strategy, achieve greater efficiency, and tap into new revenue streams, a strong presence on Amazon is increasingly becoming a fundamental requirement. It’s a platform that consistently invests in seller success and consumer experience, driving loyalty and fostering an environment where quality and service are rewarded.
