All the moving parts, working together

Run stock, listings, pricing, and fulfilment in one connected workflow instead of juggling separate tools.

One Inventory That Stays in Sync

Manage your singles in one place, then push stock, product details, SEO, barcodes, and channel listings across Shopify and marketplaces without duplicate admin.

Cardmarket Without the Admin

List and maintain Cardmarket from the same workflow you use for stock. Cut listing drift, oversells, and the daily cleanup that slows busy teams down.

One Workflow for Every Order

Bring Shopify, marketplace, and in person orders into one pick, pack, and ship flow. Connect Royal Mail C&D, ShipStation, and your existing fulfilment setup without extra handling.

Automated Repricing, Your Rules

Set the rules by game, rarity, condition, and finish, and Card Companion automatically reprices cards using aggregated market data so you stay aligned to the current market without losing control of margin.

What stores say about us

"We have been incredibly impressed with the Card Companion app since migrating our singles system over to it. We have seen immediate results, with our singles sales increasing five fold as soon as it went live."

Rob Davy-Cripwell
Boards & Swords
"We can't recommend Card Companion enough. If you're looking for a team that goes above and beyond to deliver an exceptional product, they're the ones to call."

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."

Built for stores outgrowing basic tools

Pricing That Scales With You

Pay based on managed products and orders, so cost grows with real volume instead of jumping into bloated tiers before you need them.

Keep Shopify at the Core

Keep Shopify as your storefront and let Card Companion handle the singles workflows around catalogue management, marketplaces, repricing, and fulfilment.

Stay in Sync Across Every Channel

Keep inventory and orders aligned across Shopify, POS, Cardmarket, and other channels, so busy days do not turn into oversells and cleanup work.

Market-Aware Repricing

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 inputs, so you can keep the tools you already use and get new cards live faster.

Buylists Without the Busywork

Capture buylists, review them, price accepted cards, and turn them into live inventory without spreadsheets or double entry.
