SpeX Buyback – NPC Buyback / Sellback System

💰 Premium FiveM NPC buyback and sellback system with a moving buyer NPC, stylish NUI interface, configurable item resale, company/player revenue split and built-in anti-exploit protection.

SpeX Buyback turns simple item selling into a more immersive RP loop by using a mobile buyer NPC that changes location, a polished interface and a fully configurable resale system adapted to legal, semi-legal or business-based server activities.

🌐 Description

SpeX Buyback is a modern FiveM item buyback system designed for immersive servers that want more than a static sell point.

Players must find and interact with a mobile buyer NPC who moves between configured locations. Once found, they can sell authorized items through a premium NUI interface with live price calculation, quantity selection and revenue split preview.

This creates a more dynamic and rewarding gameplay loop for jobs, gathering activities, logistics or server economies based on item resale.
