ListoMax is a Windows desktop application for e-commerce sellers and agencies managing PrestaShop and WooCommerce stores. Users enter product data—including names, descriptions, prices, VAT, stock, dimensions, EANs, categories, attributes, SEO tags, questions and answers, and images—in one workspace and publish it directly through the stores’ official interfaces, without exporting and re-importing files or copying and pasting. The software supports product content in up to eight languages, CSV and Excel supplier imports, product variants, and a Series feature that creates multiple separate listings from one form, each with its own reference and page for products offered in different colors or sizes. A Google search preview helps users review SEO fields, while version history supports catalog updates. Upload errors identify the affected product, store, and reason, and can be retried. ListoMax offers a one-time license and five free publications for evaluation.
