Everything you need to start selling on Poland's dominant marketplace in 2026
Allegro is the undisputed king of Polish e-commerce, commanding over 35% market share with 200+ million monthly visits and 20 million active buyers. For context, Amazon.pl holds only 3-5% of the Polish market — if you want to reach Polish consumers, Allegro is not optional, it is essential.
What makes Allegro attractive for international sellers is the combination of massive traffic, competitive fee structures (starting at 5.5%), and a rapidly growing cross-border seller program. Poland's e-commerce market exceeded €18 billion in 2025 and continues to grow at 15%+ annually, making it the largest market in Central and Eastern Europe.
This guide walks you through every step of launching on Allegro: from eligibility requirements and account setup to listing optimization, fee management, fulfillment options, and the common mistakes that trip up international sellers. Whether you're expanding from Amazon, Shopify, or WooCommerce, you'll find actionable advice for each stage.
