Importing Your Sales
Track revenue and calculate profit on every card
Why import sales?
- Sales complete the P&L picture — revenue minus cost basis equals profit
- When linked to cards, CardZen automatically calculates net profit per card
- eBay sales include detailed fee breakdowns (final value fees, promoted listing fees, shipping label costs)
3 Ways to Import Sales
1. eBay Sales Sync (recommended)
- Connect your eBay account (same connection used for purchases)
- Click "Sync eBay Sales" on the Sales page
- Pulls completed orders from the last 90 days via the eBay Finances API
- Includes full fee breakdown: final value fees, promoted listing fees, payment processing, shipping costs
- Auto-deduplicates — safe to sync multiple times
2. CSV Import (for historical sales)
- Perfect for sales older than 90 days
- Supports two eBay export formats:
- Listings Sales Report (recommended) — detailed fee breakdown, download from Seller Hub → Performance → Listings
- Orders Report (legacy) — basic order info, download from Seller Hub → Performance → Orders
- CardZen auto-detects the format
- Handles up to 2+ years of history
3. Manual Entry (for off-platform sales)
- Simple form: platform, date, price, shipping cost, platform fees
- Platform options: eBay, Facebook Marketplace, COMC, Card Show, Other
- Optional: order ID, notes, tracking number
Linking Sales to Cards
- After importing, sales show a "Needs Linking" flag if no card is connected
- The auto-link engine tries to match sales to cards automatically (especially eBay sales via item ID)
- Manual linking: open a sale and search for the card
- Once linked, profit/loss is calculated automatically
Tips
- Sync eBay sales regularly — it only pulls the last 90 days
- Use CSV for your historical archive (before you started using CardZen)
- Off-platform sales (card shows, Facebook) still count in your P&L — enter them manually
