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
- Need older sales? Click "Sync history" next to it, pick a date, and CardZen fetches everything from that date forward. eBay keeps two years of orders, so that is as far back as it can go. The sync shows its progress and can be resumed if you close the window
2. CSV Import (for historical sales)
- Perfect for sales older than two years, which is as far back as eBay keeps order history
- 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 to stay current, and run "Sync history" once to bring in everything eBay still has
- 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
