How Trade-in Works in Nexa One

Trade-in transactions are atomic — the used item enters inventory AND the sold item is marked sold in one database transaction. This ensures your books are always balanced. To create a trade-in: 1. Go to POS → Trade-in 2. Search for the item the customer wants to buy 3. Add the customer's used item with condition photos 4. Set prices for both sides 5. Complete the transaction The system automatically creates the correct invoice entries and stock movements.
