A website for a manufacturer of outerwear was created on the OpenCart 3.0 platform. A ready-made template was used with further customization to meet the client's needs, including design settings, page structure, and catalogs. Necessary modules for payment, delivery, and other functional capabilities were connected, and additional functionality was implemented according to the client's requirements. To improve the website's performance, speed optimization and basic SEO settings were conducted. A special feature was the automatic updating of prices and product availability from the KeyCRM system, which ensures the relevance of the catalog and convenience in managing the assortment.
