01 Reach more buyers

Reach buyers beyond your website.

Some customers browse your website. Others head straight to Cardmarket or CardTrader. Connecting your store lets you offer the same cards in the places they already shop.

Start with the products you’ve already created. Once you’ve connected a seller account and checked its settings, you can list from that catalogue without building each product again.

One catalogue. More places to sell.

Choose the marketplaces that suit your store.

02 Keep stock in sync

A card sells. Your other listings need to know.

When you sell a card, add stock or adjust a count, Card Companion keeps your store stock and connected marketplace listings in sync. You can manage the same stock in one place, with less to update by hand.

03 Stay in control

Start with the marketplaces you know.

Choose a supported marketplace your customers already use. You’ll need your own seller account, and you’ll give Card Companion permission to connect to it. Check your pricing and listing settings before you publish.

Selling on eBay takes setup through Shopify Marketplace Connect too. Your marketplace accounts stay yours, with their own fees and settings. You can connect more supported marketplaces when you’re ready.
