Challenge

A collectible card shop handled buyouts entirely by hand. Customers brought in collections, and staff had to look up each card on CardMarket, assess condition, and calculate the buyout price. A single 200-card buyout could take over 3 hours. There was no inventory tracking, and VAT margin accounting was done manually. The shop also had no storefront of its own. All sales went through CardMarket, where platform fees significantly reduced margins. They needed a unified system for the entire business cycle.

Solution

We built a platform that automates the entire card lifecycle from buyout to sale. Customers search for cards online, select condition, and instantly see a buyout offer based on current market prices. The backoffice covers the full process: buyout approval, physical inspection, and stocking into an album system with the exact location of every card. A dedicated e-shop with cart reservation enables sales at higher margins than external platforms. VAT margin accounting is generated automatically.

  • Online buyout portal where customers prepare their own card lists with automatic pricing
  • Album-based inventory system with exact card locations and photographs
  • Dedicated e-shop with cart, reservation, and online payments
  • Automated accounting for VAT margin scheme under § 66
  • Complete backoffice for managing buyouts, inventory, and orders
