Media Expert, Poland’s largest consumer electronics chain, has launched a marketplace and opened to verified external sellers. Beyond electronics and household appliances, the platform is expanding its catalogue into FMCG, pet products, toys and sports accessories. For your brand, this is a fresh channel with heavy traffic and strong logistics behind it. We help you meet the quality requirements, integrate your offers and run sales with a focus on quality and fast dispatch.
Countries where the platform is active: Poland.
Related services: integration and automation, content and rich media, pricing strategy.
Note: every platform runs its own, often selective, seller qualification and decides independently whether to accept an offer. We help you meet the requirements, prepare and submit the application properly and manage the process, but we cannot guarantee acceptance, because that decision belongs to the operator.
What we do on Media Expert
Registration and verification
We guide you through seller registration and verification, complete the required data and meet the quality standards: products entered correctly and in full, a capped late-dispatch rate, and message response times within 24 hours.
Listings and the product feed
We build the catalogue and feed to the platform's requirements: grouping by EAN codes, attributes and variants. We organise your product data so offers are complete, correctly matched and ready to publish.
Integration and automation
We connect offers, stock and orders to your system. We automate the data flow and updates to cut manual work and keep your offers and prices consistent over time.
Visibility and promotions
We help your products get seen with competitive pricing, complete product data and strong seller metrics. We run promotions within what the platform allows.
Logistics and service
We design a shipping and order handling model that meets Media Expert's expectations, including fast delivery times. We help set up logistics and returns processes that keep your account metrics high.
Account management and optimization
We can also run the account day to day: monitoring sales, prices and quality metrics, responding to change and optimising your offers. Our focus is growing Media Expert's share of your revenue.
How the collaboration works, step by step
Fit check
We match your catalogue against the platform’s profile: consumer electronics and home appliances, and beyond them FMCG, pet products, toys and sports accessories.
Registration and verification
We open the seller account, complete the required company data and take it through verification.
Catalogue and feed
We build the feed to the platform’s requirements: grouping by EAN codes, attributes and variants, with complete data ready to publish.
Integration and logistics
We connect offers, stock and orders to your system, and set up the shipping and returns model for fast delivery times.
Running the channel
Prices, visibility, promotions and account quality metrics, with a response to what changes in the category.
Who this is for
We work with brands that already have a ready catalogue and are looking for another channel in Poland next to their own shop. The fit is best when:
Your catalogue sits in consumer electronics and home appliances, or in the categories the platform is expanding into: FMCG, pet products, toys and sports accessories.
Every product carries an EAN code, because that is how the platform groups offers.
You can hold fast delivery times and stay inside the cap on late dispatches.
Your customer service answers messages within 24 hours, because that is the platform standard.
