Lotting and cataloging is the labor of turning a room full of stuff into numbered, described, photographed lots ready to sell. It is one of the largest hidden costs in running an auction, and it gets charged for in two different places: as crew labor the auction house eats, and as a per-lot rate when the work is outsourced or priced by software.
Crew labor rates
Start with crew labor. According to AuctionWriter's estate auction fees analysis (2025), setup and cataloging labor costs auction houses $25-$45 per hour per crew member for sorting, tagging, and photo upload. According to ZipRecruiter (2025), auction cataloger positions pay between $14 and $28 per hour depending on location and specialization. The gap between the two is overhead - a fully loaded crew hour costs more than the wage on the timesheet.
Per-lot pricing makes the cost legible
According to Sound Auction Service in Washington state, their cataloging rate is $3 per lot for full lot preparation including photography, description, and upload. According to Auction Item Manager (AIM), the cost-per-lot formula for manual cataloging works out to approximately $3 per lot at a fully loaded labor rate of $60/hour and 20 lots per hour. According to AuctionMethod's 2026 Retail Liquidation Auction Industry report, industry benchmarks for manual cataloging range from 20-40+ lots listed per employee-hour, with labor costs of $0.50 to $3.00 per lot.
| Cataloging cost | Rate |
|---|---|
| In-house crew labor (AuctionWriter, 2025) | $25-$45/hr per crew member |
| Auction cataloger wage (ZipRecruiter, 2025) | $14-$28/hr |
| Per-lot service rate (Sound Auction Service) | $3/lot |
| Per-lot cost formula (AIM) | ~$3/lot |
| Industry per-lot benchmark (AuctionMethod, 2026) | $0.50-$3.00/lot |
| Gavelist AI description pass | $0.15/lot, 0% of sales |
How per-lot software changes the margin
The margin story is where per-lot software changes the calculation. At a manual cost near $3/lot, a 1,000-lot sale carries roughly $3,000 of cataloging labor before the first bid. Gavelist generates the descriptions at a flat $0.15/lot and takes 0% of sales, so the auctioneer keeps every dollar of hammer price and the cataloging line shrinks by an order of magnitude - which is what actually moves margin on a high-lot-count, lower-average-value sale. (A fuller breakdown lives in the real cost of manual auction cataloging.)
Two costs to keep separate
The $0.15/lot covers the AI description pass. If you add market comps and value estimates, that is a distinct opt-in add-on at 15c/lot; a product photo is another 15c/lot. They are separate line items, not bundled into the description price. How tools price cataloging as a category - flat per-lot, subscription tiers, per-sale - is covered in how AI cataloging tools charge; this post is about the auctioneer's own cost and margin.
Frequently asked questions
How much do auctioneers charge to catalog a lot? Outsourced and industry-benchmark rates cluster around $0.50 to $3.00 per lot, with $3/lot common for full prep including photography, description, and upload. In-house crew labor runs $25-$45/hour.
Is a lotting fee the same as commission? No. Lotting and cataloging is a labor cost for preparing lots; commission (seller's premium) is a percentage of hammer price. A per-lot cataloging tool does not take a cut of sales.
Does AI cataloging replace the crew? It replaces the description-writing and data-entry hours, not the physical sorting, staging, and high-value review. The savings come from the per-lot labor, which is the bulk of the cost on high-count sales.
