I’m building a web platform dedicated to selling tickets for music concerts and I need it to feel as seamless as the big players. The core flow is straightforward: fans browse an event page, see an interactive seat map, watch seats change colour in real-time as they’re snapped up, choose their spot, and check out securely with a credit or debit card. Alongside my own events, I also want a promoter marketplace. Approved promoters should be able to sign in, create or import their shows, set prices, and release their own seat inventory while the system automatically tracks our agreed commission on every ticket sold. A simple dashboard that breaks down earnings for both sides will keep everyone happy. Must-have functionality • Interactive seat maps that work on desktop and mobile, with real-time availability updates. • Secure card payments (Stripe or a similar PCI-compliant gateway is fine). • A promoter portal with event creation, seat allocation, sales analytics, and automatic commission calculation. • Admin controls for me to override prices, issue comps, refund, or close a section instantly. • Clean, modern UI and fast page loads; React/Next.js with a Node or Laravel back-end is ideal but I’m open to another stack if you explain the advantages. Acceptance criteria 1. I can upload a new venue layout, mark sections, rows, and seats, and see it render instantly on the front end. 2. A test purchase shows the seat locked for five minutes, then released if abandoned, or marked sold once payment clears. 3. A promoter account logs in, publishes an event, and the commission report shows the correct percentage in the admin panel. 4. Responsive design passes Google’s Mobile-Friendly test. If you have live examples of similar ticketing or seat-selection work, send them over so I can jump straight into the details with you.
