How Trade Up Works
Trade Up lets you make hybrid offers combining cash and items you already own. List, browse, offer, negotiate, and trade — all in one app.
Create Your Listing
Take photos of your item and write a description — Trade Up's AI assistant helps you craft compelling listings automatically. Set your asking price using AI-powered price estimation based on current eBay market data from SerpApi.
Browse Local Listings
Explore items listed near you in San Diego. Filter by category, price range, or distance. See what other traders have available and find items that match what you're looking for.
Make a Hybrid Offer
Found something you want? Make an offer combining any mix of cash and items you already own. For example, offer '$30 plus my Nintendo Switch' for a PS5. This is what makes Trade Up unique.
Negotiate in Real-Time
Chat with the seller directly in the app. Counter-offer, ask questions, and finalize the deal details. All communication stays within Trade Up's secure messaging system.
Complete the Trade
Once both parties agree, pay securely through Stripe Connect. Ship your item via integrated Shippo labels, or meet locally. Buyers get a 3-day inspection window before the seller's payout is released. Rate your experience to build community trust.
