I’m launching an online store focused on medical supplies—everything from gloves and masks to small diagnostic devices—and I need a full-featured ecommerce platform built (new or on a proven framework like Shopify, WooCommerce, Magento, or a custom stack). Although the core of the site is straightforward physical-product sales with real-time inventory and secure shipping calculations, three specialised features are non-negotiable: Download management for automatically delivering regulatory PDFs and user manuals, License management to track serialised devices and customer certificates, and Subscription billing so clinics can set up recurring orders for consumables. Beyond those points, the build must be PCI-DSS-compliant, responsive across devices, SEO-ready, and easy for my staff to maintain without touching code. Clean, well-commented development and an extensible architecture are important so additional modules can be added later. Deliverables 1. Production-ready ecommerce site deployed to my hosting. 2. Documentation detailing installation, configuration, and day-to-day workflows. 3. A short hand-off session (or recorded demo) walking me through the admin panel. Completion is successful when I can list a product, accept an order with saved-card subscription billing, deliver the correct downloadable files, and see the licence number tied to the buyer’s account—all from the dashboard. Please share your preferred tech stack, estimated timeline, and any similar projects you’ve handled.
