Custom Buy-Sell Ecommerce Site

Job ID: 40246666

Budget: $1,500 – $3,000 USD

I need a fully custom-built ecommerce platform that reproduces the core experience of https://uk.webuy.com/ while adding our own branding and workflow. The site must serve two distinct user journeys:

1. Buy – visitors browse live stock, add products to a basket, pay at checkout with credit/debit card or PayPal, and receive automated invoices, shipment tracking, and account history.

2. Trade-in – users search for an item, see the real-time cash and store-credit offers we set in the back-office, book the trade, generate a shipping label, and then choose to be paid in store credit (instantly to their account once items are received and checked over) or cash via PayPal or bank transfer once the item is approved.

Because I don’t have a finished visual identity, I’ll rely on you for UI/UX direction—wireframes first, then a clean, device-responsive design that feels as intuitive as CeX but clearly reflects our brand.

Key functional notes
• Custom architecture preferred so we are not boxed in by third-party modules.
• Single inventory pool drives both the retail and trade-in sides; when stock is accepted, it should instantly appear for sale.
• Dynamic pricing rules (by SKU, condition, demand) that I can adjust in the admin.
• Secure user accounts with order/trade history, gift-card or store-credit balance, and KYC checks for high-value trades.
• Payment integrations: credit/debit card (e.g. Stripe), PayPal for both sales and cash payouts, and bank transfer for payouts only.
• Conventional ecommerce features—SEO-friendly URLs, coupon codes, tax/shipping calculators, email notifications—are expected.

Deliverables
• Wireframes and final design mock-ups.
• Fully commented source code, database schema, and deployment guide.
• Admin dashboard with documentation.
• Two-week post-launch support window to fix critical bugs.

If anything in the brief is unclear, let’s clarify early—I value a transparent build process driven by milestones and testable iterations.
