Multivendor Clothing App Development

I want to turn my growing fashion business into a mobile marketplace where several independent vendors can list and sell brand-new clothing under one roof. The goal is a polished, stable multivendor app that runs seamlessly on both iPhone and Android, complete with vendor onboarding, product management, secure checkout, and an admin console for me to oversee everything.

Core needs
• Universal shopping experience on iOS and Android, with fast product search, rich images, size/colour variants, in-app payments, order tracking, and push notifications.
• Vendor dashboard for product uploads, price edits, stock updates, and fulfilment status changes.
• Web-based admin panel where I can approve sellers, moderate listings, run promotions, view sales reports, and set commission rates.
• Integration with a mainstream payment gateway and the option to connect shipping APIs later.
• Clean, well-documented code (React Native, Flutter, or fully native—your call) plus store deployment under my accounts.

Acceptance criteria
• Both apps pass App Store and Google Play review and go live.
• Shoppers can register, browse new clothing from multiple sellers, place orders, and pay securely.
• Vendors can self-register, list items, and manage their orders from a dedicated area.
• Admin panel gives me real-time insight and full catalogue control.

When you reply, outline the tech stack you recommend, link to any similar marketplace apps you have shipped, and break down the timeline into clear milestones from prototype to launch.
