Lewis McLeod
Union County Games
"Card Companion has been great for us, wish we could have moved earlier. Would (and have) recommend to any store considering going into singles."

Karl Williams
LvlUp Gaming
"Their system helps us keep a perfectly organised stock file and provides us with daily updated prices allowing us to always be in line with the marketplace across multiple platforms at once. Anyone working with TCG singles is missing out not working with Card Companion."

Harry Stapley
Stardust Cards
"I was always looking for a way to synchronize my cardmarket inventory with my website for years. As for the software, it works very seamlessly and gives you greater reach with your singles inventory. We particularly enjoy the ease of use trade in system and the auto pricing engine that tracks market trends."

David Shales
Gear Head Games
"We've worked with Card Companion for over 2 years and the service offered has been fantastic. Each update has added value to our business and we no longer have any downtime as a result of the partnership."

Pricing That Grows With You

Pay based on managed products and orders, so your cost grows with real volume instead of forcing you into higher tiers too early.

Keep Your Existing Storefront

Keep Stock and Orders Aligned

Keep inventory and orders aligned across your storefront, POS, Cardmarket, and other channels, so you avoid oversells and the cleanup that follows.

Daily Repricing, Your Rules

Use your pricing rules and aggregated market data to reprice automatically, stay competitive, and protect margin.

Bring Stock In Fast

Import from Powertools, Phyzbatch, Magic Sorter, and other sources, so you can keep the tools you already use and get new cards live faster.

Buylists Without the Busywork
