The Best Inventory Tool for eBay Trading Card Sellers
Create eBay listings in seconds, keep prices synced to market, and manage your entire inventory without spreadsheets.
The Problem with the Current Status Quo
Selling trading cards on eBay is one of the best ways to move inventory at scale. But managing it manually — creating listings one by one, updating prices when market shifts, relisting sold-out items — is a full-time job. InVelocity cuts the time from "I have this card" to "it's live on eBay" from minutes to seconds.
Sound familiar?
- Creating eBay listings manually takes 3–5 minutes per card — unsustainable at scale
- Market prices shift daily, making your listings stale and hurting your sell-through rate
- When a card sells on eBay, you have to manually update your inventory count
- Listing titles that don't follow eBay's Cassini algorithm get buried in search results
- Relisting sold-out items requires finding the old listing and manually duplicating it
- You don't know which cards in your inventory are priced above or below market
How InVelocity Solves It
Purpose-built tools for ebay card sellers — not generic e-commerce software.
One-Click eBay Listing Creation
Your card details, condition, photos, and a Cassini-optimized title are pre-filled from your inventory. Review and submit in under 10 seconds.
Automatic Price Sync
TCGPlayer market prices update daily. When you're ready to relist or reprice, InVelocity shows you exactly which listings are above or below market.
Quantity Sync When Cards Sell
eBay sale → inventory count automatically decreases. No more accidentally selling a card you no longer have in stock.
Bulk List to eBay
Select 50 drafts and list them all to eBay with one button. InVelocity queues them up and handles the API calls — you watch the listings appear.
Price & Volume Alerts
Get notified when a card in your inventory jumps in price or trading volume. List at the new market price before your competitors have updated theirs.
Restock What Sells
InVelocity tracks which cards you've sold fastest and surfaces them as restock suggestions — ranked by profit opportunity.
