Castorama Marketplace allows third-party companies to offer products directly on castorama.pl. For manufacturers, importers and distributors in the home, garden, renovation, construction and interior design sectors, this can be a valuable channel for reaching customers with a specific purchasing intention. However, it is not an open platform where an account is automatically activated upon registration. Kacper Pawlak, Marketplace Specialist at bTOP, explains how to become a Castorama Marketplace seller, how Mirakl works, what costs and obligations need to be taken into account, and what factors influence Read more
eBay is one of the largest international marketplace platforms. According to data from eBay Inc., the platform brings together 136 million active buyers, around 2.6 billion active listings and users from over 190 markets. For a Polish company, this means the opportunity to start selling abroad without having to set up a separate shop in every country. At the same time, eBay is not a single, identical service across the globe: individual markets have their own fees, rules, languages and customer expectations. Kacper Pawlak, Marketplace Specialist at bTOP, explains how to set up Read more
The eMAG Marketplace enables Polish companies to sell in three key markets in Central and Eastern Europe: Romania, Hungary and Bulgaria. For sellers, this means the opportunity to expand their international sales within a single ecosystem, but simply setting up an account is not enough. You need to prepare your company’s documents, a product catalogue, correct prices, localised versions of your offers, logistics and a method for synchronising stock levels. The biggest advantage of eMAG is the ability to utilise the Cross-Border model. Sellers can expand their sales into further countries without having to build separate processes from scratch Read more

The Media Expert Marketplace allows customers to shop from both Media Expert and third-party sellers. For a company developing its online sales, preparing a listing means combining an accurate product presentation with terms and conditions that can be honoured after the purchase. The customer should be able to easily identify the model and variant, check its features, and understand the price and delivery date. Before you start editing descriptions or reducing prices, it is worth familiarising yourself with how products and offers are presented on the platform. How does a product page differ from a seller’s offer? Product page Read more
From 27 September 2026, the e-commerce market and the entire retail sector across the European Union will face a new legislative challenge.

The Leroy Merlin Marketplace allows third-party sellers to offer products directly on the leroymerlin.pl website. For businesses in the home, garden, renovation, interior design or DIY sectors, this can serve as an additional sales channel, but simply setting up an account is not enough. Accurate product data, a comprehensive product range, logistics and compliance with the platform’s requirements are all of great importance. Comment from a bTOP expert: Leroy Merlin is not a platform where you should start by haphazardly importing your entire catalogue. First, you need to ensure that the products fit into the relevant categories, Read more
A successful listing on OTTO Market starts with accurate product data. The platform uses the category, brand, attributes and variant data not only to present the product, but also to build the title, filters and shopping paths on otto.de. A lack of required information may prevent publication or limit the visibility of the listing. Kacper Pawlak, Marketplace Specialist at bTOP, shows how to prepare a catalogue without repeating mistakes made on other platforms. As an OTTO Market Service Partner, we support sellers with data mapping, integration and resolving errors that prevent publication. Product, Read more
