Refurb Product Inventory Web App

I need a web-based inventory management system tailored to the realities of selling refurbished electronics. The core application must be accessible through any modern browser, with any optional desktop utilities (label printers, bulk-uploader, etc.) working smoothly on Windows.

Here is what the first release needs to cover:

• Product tracking with custom SKU, full model name, and graded condition
• Real-time stock alerts so I can reorder or pause listings before overselling
• Sales reporting that breaks down performance by channel, model, grade, and date range
• Multi-channel sync (Amazon to start, but structured so eBay, Shopify, etc. can be added through APIs)
• Battery-health, serial number, and IMEI fields stored and searchable
• Warranty & return management that ties back to the original sale record
• Invoicing plus accounting integration

Clean, responsive UI, role-based access, and a sensible relational database are expected. I will supply sample CSV exports from my current spreadsheets, along with API tokens for the initial Amazon account so you can map the data structure.

I’m ready to get started as soon as we agree on a schedule and milestones.
