Importing Your Purchase History
Track what you paid so CardZen can calculate your profit
Why import purchases?
- Purchases are the foundation of profit tracking — without a cost basis, CardZen can't calculate P&L
- When you import purchases, CardZen creates placeholder cards and auto-batches
- When you later capture those cards, the auto-link engine connects them to their purchase automatically
- You can import at any time — purchases link to cards retroactively too
4 Ways to Import Purchases
eBay Auto-Sync
Recommended for eBay buyers- Connect your eBay account in Settings
- CardZen pulls your purchase history from the last 60 days
- Each purchase appears with seller, price, date, and item details
- Confirm each one — set the type (single, lot, box, etc.) and quantity
- Tracking numbers and shipping status sync automatically
CSV Upload
Best for bulk historical data- Great for importing months or years of purchase history at once
- Required columns: purchase_date, type, seller, quantity, subtotal
- Optional: source, order_number, shipping, tax, fees, discount, notes
- Download a template from the upload dialog
- Preview your data before importing — CardZen auto-maps columns
AI Quick Add
Best for receipts and invoices- Upload a photo of a receipt, screenshot of a DM, or an invoice PDF
- AI extracts: seller, date, cost breakdown, and individual card line items
- Preview the parsed data before saving
- Costs 1 token per use
- Works on both web and mobile
Manual Entry
For card shows, private sales, trades- Full form with: seller, date, source, type, quantity, cost breakdown
- 16 source options: eBay, Goldin, Heritage, card show, social media, private sale, etc.
- Cost breakdown: subtotal + tax + shipping + fees - discount = total
What happens after import
- For singles: placeholder cards are created (1 per quantity), linked to the purchase
- For lots/boxes: a lot container card is created, linked to the purchase
- An auto-batch is created for each purchase with status "awaiting capture"
- When you photograph cards into these batches, they replace the placeholders
- Purchase workspace shows a journey tracker: Ordered → Shipped → Arrived → Captured → Linked → Ready
Tips for bulk onboarding
- Start with eBay sync to cover recent purchases automatically
- Use CSV for anything older than 60 days
- You don't need to import everything on day one — import as you go
- Purchases without photos still show up in reports and P&L
