Keep your singles workflow connected

Manage inventory, listings, pricing, and fulfilment in one Shopify-connected platform built to reduce manual work and keep your operation under control.

One Inventory That Stays Accurate

Manage your TCG singles inventory in Card Companion, with your sales channels connected to the same stock record. When a card sells anywhere, inventory updates in one place.

Cardmarket Built In

Card Companion lets you list directly to Cardmarket from your central inventory. Listings and stock stay updated in real time, so you can avoid oversells and stop wasting time on manual fixes.

One Place to Fulfil Every Order

Bring Shopify, marketplace, and in-person orders into one fulfilment flow. Pick, pack, and dispatch from one place using your existing setup.

Set the Rules. Prices Update Daily.

Card Companion automatically updates card prices every day based on your rules and market data. Stay current with the market, protect margin, and spend less time repricing by hand.

Card Companion is not trying to replace every tool in your business. Shopify stays central while Card Companion keeps high-volume singles work connected around it, so your team spends less time on oversells, repricing, cleanup, and disconnected stock records.

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."
