Mejix delivers custom development, complex integrations, and high-performance commerce for global brands. ## Engineered for Performance: Certified Shopify Plus Expertise In the world of high-volume ecommerce, your platform is only as strong as the engineers who build it. Mejix Inc. is not just another agency; we are a dedicated Shopify Plus development company serving as a strategic engineering partner for brands that have outgrown standard solutions. As a verified Shopify Plus Partner at the Plus Tier, we represent the highest level of technical certification within the Shopify ecosystem. Based in New York, we provide US enterprise brands with the specialized expertise required to navigate the complexities of high-scale digital commerce. Working with a certified Plus Tier partner means your brand gains access to advanced platform capabilities that are often inaccessible to standard developers. From implementing bespoke Checkout Extensibility to building custom Shopify Functions that replace outdated Shopify Scripts, our team ensures your store is optimized for maximum efficiency. Since 2022, we have helped brands across the B2B, fashion, beauty, and jewelry sectors launch and scale multi-million dollar storefronts that prioritize performance, security, and conversion. ## Comprehensive Enterprise Solutions & Systems Integration Mejix specializes in the technical 'heavy lifting' that enterprise commerce demands. Our core services are designed for companies that require more than just a retail template. We excel in Shopify Plus migration services, helping brands move seamlessly from restrictive platforms like Magento, BigCommerce, and WooCommerce. Our migration process focuses on data integrity, ensuring that complex product catalogs, customer data, and mission-critical SEO rankings are protected during the transition. Beyond the initial build or migration, we provide the deep-level integrations that power modern enterprises. Whether you need to sync your Shopify Plus store with an ERP like NetSuite or SAP, a specialized CRM, or an advanced Order Management System (OMS), our developers build robust, scalable bridges between your core operations and your storefront. This holistic approach to enterprise Shopify Plus development ensures that your digital presence is fully harmonized with your logistics, inventory, and customer service workflows. ## Drive Growth with Headless Commerce and Advanced CRO Success in the Shopify Plus ecosystem requires a commitment to constant evolution. Mejix doesn't just launch your store; we optimize it for long-term ROI. Our Conversion Rate Optimization (CRO) services are data-driven and technically grounded, focusing on sub-second page speeds, intuitive UX design, and the implementation of AI-driven features like smart search suggestions and personalized recommendations. We understand that for an enterprise brand, a 1% increase in conversion can result in millions of dollars in additional annual revenue. Furthermore, we are at the forefront of the Headless Commerce movement. By utilizing Shopify Hydrogen and Oxygen, we build decoupled storefronts that offer unparalleled flexibility and speed. This approach is ideal for brands looking to differentiate themselves through unique digital experiences or those managing complex international setups with multi-currency and multi-language requirements. With Mejix, you are choosing a partner that views ecommerce as a technical discipline, ensuring your brand stays ahead of the curve in an increasingly competitive landscape. ## Frequently Asked Questions ### Is Mejix a certified Shopify Plus Partner? ### What specific services does Mejix offer for Shopify Plus? ### Where is Mejix located? ## Keep Reading Landing_Page ### Shopify Plus Migration Services for Enterprise Brands Migrate to Shopify Plus with zero data loss.
