Marqetir helps e-commerce sellers list products across European marketplaces. Allegro, Amazon, Kaufland, Otto, MALL — each one has different rules for titles, descriptions, categories, images, and attributes. Right now, sellers copy-paste product data into each platform and fix compliance errors by hand. Existing tools like BaseLinker still need weeks of configuration. We pull your catalog from Shopify, WooCommerce, your ERP, or a spreadsheet, and use AI to adapt each product to each marketplace's format. Categories get mapped, content gets rewritten to fit character limits, and required attributes get filled in — so listings actually go through on the first try. After that, stock and price updates sync across all channels automatically. Orders from every marketplace show up in one plaƒce. Built for sellers in Central and Western Europe who are expanding to new marketplaces and don't want to hire someone just to manage listings.
