Getting Started as a Seller

Selling on CardNexus is simple — if you have cards in your collection, you can list them on the marketplace in just a few clicks. Here’s everything you need to know to get started.

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 — additional verification is only required when you request your first payout. 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. Enter your first name, last name, and date of birth — required to start listing on the platform
  2. Pick your country — this is a critical choice. Your country determines:
    • The currency your listings will be displayed in (determined by your country — e.g., EUR, GBP, SEK, USD)
    • Your location shown next to your seller name on product pages
    • Your shipping rates (default rates are assigned based on your country)
  3. Select your seller type — Individual or Professional (see below)

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
  • Additional identity verification is only required when you request your first payout
  • Perfect for selling off part of your collection or testing the waters

Professional Sellers (Coming Soon)

During onboarding, you’ll see the option to register as a Professional seller (for local game stores and professional resellers). This option is not yet available — if you select it, you won’t be able to proceed. Stay tuned — professional seller support is coming very soon.
