Typing individual LEGO minifigure listings on Whatnot kills your profit margins. You spend hours entering part numbers, descriptions, and prices while your inventory sits unsold. Smart resellers scan their minifigures in bulk, generate accurate data, and upload everything to Whatnot in minutes instead of hours. The faster you list, the faster you sell. Here's how to build a bulk upload workflow that actually works for serious LEGO resellers.

Scan your minifigures in bulk first

Before you touch Whatnot's interface, scan all your minifigures at once. Bulk scanning tools identify parts automatically and pull current market values. You get accurate part numbers, descriptions, and suggested prices without typing anything.

Take photos of 10-20 minifigures at once. The scanning tool identifies each figure and creates a complete inventory list. This beats photographing and researching each figure individually.

Export inventory data to CSV

Once you scan your inventory, export everything to CSV format. Your CSV file contains part numbers, descriptions, conditions, and current market prices. This data feeds directly into Whatnot's bulk upload system.

Make sure your CSV includes these columns: title, description, starting price, buy-it-now price, category, and condition. Whatnot's bulk upload tool expects specific formatting.

Format data for Whatnot's requirements

Whatnot has specific requirements for bulk uploads. Your titles need keywords buyers actually search for. Include "LEGO minifigure" plus the character name and series.

Set starting prices 20-30% below market value to generate bidding activity. Use buy-it-now prices at or slightly above current market rates. Whatnot's algorithm favors listings that generate quick engagement.

Upload and schedule your auctions

Whatnot lets you upload multiple listings and schedule them for different times. Spread your auctions across peak hours when collectors are actively browsing. Don't dump everything at once.

Schedule higher-value figures for evening hours when bidding activity peaks. List common figures during daytime hours to capture casual buyers.

Track what sells and adjust

Monitor which figures sell quickly and which sit unsold. Adjust your pricing strategy based on actual results, not just market guides. Whatnot's audience pays different prices than other platforms.

Relist unsold items with lower starting prices or better photos. Sometimes a simple title change doubles your bids.
