Moving your BrickLink inventory to Whatnot means more sales channels and higher prices for rare minifigures. But manually recreating hundreds of listings kills your profit margins with wasted time. The smart move is bulk importing your existing BrickLink data to Whatnot, keeping descriptions, prices, and photos intact. This guide shows you the fastest methods to transfer your inventory between platforms without losing your sanity or your weekend.
Export your BrickLink inventory
BrickLink offers inventory export through your seller account. Navigate to My Store > Inventory and select Export. Choose CSV format and include all fields - item numbers, descriptions, quantities, and prices. This creates your master file for importing elsewhere.
For minifigures specifically, make sure your export includes BOID (BrickLink Object ID) numbers. These unique identifiers help match items across platforms and prevent listing errors.
Convert BrickLink data for Whatnot
Whatnot requires specific formatting that differs from BrickLink's export structure. Your BrickLink CSV needs column adjustments before uploading.
Key changes needed:
- Title field: Combine item name and condition
- Category mapping: Match BrickLink categories to Whatnot equivalents
- Price formatting: Remove currency symbols, use decimal format
- Image URLs: Convert BrickLink image links to direct URLs
Bulk scanning speeds up the process
Manual data conversion takes forever with large inventories. Bulk scanning tools read your physical inventory and generate properly formatted files for multiple platforms simultaneously.
Scan your minifigures in batches, verify pricing against current market rates, and export directly to Whatnot-compatible formats. This eliminates manual typing and reduces listing errors that hurt sales.
Upload to Whatnot seller tools
Whatnot's bulk import feature accepts properly formatted CSV files. Access this through your seller dashboard under Inventory Management. Upload your converted file and review any flagged items before publishing.
Common upload issues include missing required fields, invalid category assignments, and duplicate listings. Check your file against Whatnot's template before uploading to avoid delays.
Sync inventory levels between platforms
Selling on multiple platforms means tracking inventory across all channels. When items sell on Whatnot, update your BrickLink quantities to prevent overselling.
Consider inventory management tools that sync automatically between platforms, or establish manual processes for daily updates. Overselling damages seller ratings and costs money in canceled orders.

FAQ
Can I directly import from BrickLink to Whatnot?
Whatnot doesn't offer direct BrickLink integration. You need to export from BrickLink as CSV, reformat the data to match Whatnot's requirements, then upload through Whatnot's bulk import feature.
What happens to my BrickLink photos when importing to Whatnot?
BrickLink photos don't automatically transfer. You'll need to either re-upload images to Whatnot or use image URLs if you host photos externally. Most resellers take new photos optimized for Whatnot's live selling format.
How do I handle pricing differences between platforms?
Whatnot typically supports higher prices than BrickLink, especially for rare minifigures. Adjust your pricing during the import process rather than copying BrickLink prices directly. Research completed Whatnot sales for comparable items.
Will my BrickLink inventory automatically sync with Whatnot?
No automatic syncing exists between these platforms. You'll need to manually update inventory levels when items sell on either platform, or use third-party inventory management software that supports both platforms.
