ListoMax is a desktop application designed for Windows that assists e-commerce sellers and agencies in managing their PrestaShop and WooCommerce stores effectively. It allows users to input comprehensive product information—including titles, descriptions, pricing, VAT, inventory levels, dimensions, EANs, categories, attributes, SEO tags, FAQs, and images—within a single interface, enabling direct publication through the stores’ official platforms without the hassle of file exports, imports, or manual data transfers. This software accommodates product information in as many as eight languages, supports supplier imports via CSV and Excel formats, and facilitates the creation of product variants. Additionally, it features a Series function that generates multiple distinct listings from a single entry, each tailored with its own reference and page for items available in various colors or sizes. A Google search preview assists in reviewing SEO elements, while version history ensures that users can keep track of catalog modifications. In case of upload issues, the software promptly identifies the specific product, store, and the nature of the error, allowing for a straightforward retry process. ListoMax provides a one-time licensing option alongside five complimentary publications for users to assess its capabilities before making a commitment. Ultimately, this tool streamlines the management of e-commerce products, enhancing efficiency for sellers and agencies alike.
