What You Need

To sell on CardNexus, you'll need:

  1. A CardNexus account — sign up for free at cardnexus.com

  2. Cards in your inventory — import your collection via CSV import, text paste, or manual entry

How Selling Works

CardNexus is an inventory-first marketplace. That means your collection is your listing source — no need to re-enter card details on a separate selling page.

Here's the flow:

  1. Add cards to your inventory — import or scan them in

  2. List items for sale — select cards, set your prices, and publish

  3. Your listings go live — buyers can find and purchase them immediately

  4. When something sells, your inventory updates automatically — no manual bookkeeping

You don't need to complete full identity verification upfront. Individual sellers can start listing and selling right away — identity verification is required after your first sale, with 14 days to complete it. See seller verification for details.

Becoming a Seller

The first time you try to list a card for sale — whether from a product page or by selecting items in your inventory — CardNexus will guide you through a quick onboarding flow:

  1. Pick your country — this is a critical choice, and the country you choose must match your account's location. Your country determines:

    • The currency your listings will be displayed in (EUR, USD, GBP, CHF, SEK, DKK, NOK, PLN or HUF)

    • Your location shown next to your seller name on product pages

    • Your shipping rates (default rates are assigned based on your country)

  2. Select your seller type — Individual or Professional (see below)

  3. Tick the two confirmation boxes — required to continue

Right after, your personal details — first name, last name, and date of birth — are collected through Stripe's secure form.

Once onboarding is complete, your listing goes live and you're a seller.

Your country selection is permanent and cannot be changed later. Make sure you choose the right one — it determines your listing currency, shipping rates, and displayed location for all future sales.

Seller Types

Individual Sellers

  • This is the default path — designed for hobbyists and casual sellers.

  • Start selling immediately — no additional verification needed upfront

  • Identity verification is required after your first sale — you have 14 days to complete it

  • Perfect for selling off part of your collection or testing the waters

Professional Sellers

During onboarding, you can register as a Professional seller (for local game stores and professional resellers). Professional selling is available for sellers in the European Union — your company details are collected at onboarding, and business verification applies. Individual sellers can also upgrade to a professional account later from their settings. Professional selling is not yet available for North American sellers.
