FastTradein is cloud-based trade-in software for phone and electronics stores. Retailers add a device valuation widget to their website and manage online requests, in-store intake and inspections in one workspace. Customers receive a preliminary estimate based on the store’s own prices and their answers about device condition. Staff inspect the device, record its IMEI or serial number, and agree on the final offer. If the condition differs, the customer can accept or decline a revised offer by link. The workspace supports handover records and store-issued vouchers. The store buys the device, pays the customer and owns the customer relationship. FastTradein provides the software and charges a monthly subscription with 0% transaction commission. Application data is stored in Germany (EU). Starter is $29/month, Business $99/month and Pro $199/month, plus applicable taxes. All plans offer a 14-day free trial with no card required.
