Best AI Auction Cataloging Software (2026)

Updated September 22, 2026: added ListerLeo and Lot Lingo, re-checked every vendor's pricing on its own website, and refreshed Gavelist's production numbers through September. See what changed in September 2026.

Auctioneers used to have two ways to get lot descriptions written: pay staff by the hour to type them one at a time, or push the work to evenings and weekends. According to Sound Auction Service's published rates (accessed September 2026), full lot preparation (photography, title and description, and upload) is billed at $3.00 per lot. Today at least seven AI tools compete for that work. This guide compares Gavelist, AuctionWriter, Estimint, ListerLeo, Lot Lingo, Circuit Auction and Bidsquare Cloud on price, speed, photo handling, export breadth and workflow fit. Every competitor price below was checked on the vendor's own website on September 22, 2026.

Which AI Auction Cataloging Software Is Best in 2026?

No single tool is best for every auctioneer. Gavelist charges $0.15 per lot pay-as-you-go or $79 a month for 1,000 lots, takes 0% of auction sales, and processes 1,000+ lots in about 10 minutes (roughly 6,000 lots per hour) while reading every photo in each lot together. AuctionWriter's pricing table lists a free plan of 50 new lots a month, and it has native iPhone, iPad and Android apps. Estimint starts at $29 a month and adds consignment agreements from its $89 Pro plan and live clerking and invoicing from its $149 Auction Pro plan. ListerLeo charges a flat $119 a month for unlimited items and is built around barcode scanning and warehouse locations. Lot Lingo charges a flat $200 a month and exports to K-BID, HiBid, eBay and Whatnot. Circuit Auction is an all-in-one collectibles platform that sells AI cataloging as a $250-a-month add-on. Bidsquare Cloud is inventory and auction management software from Bidsquare, with AI cataloging announced in January 2025.

Why AI Cataloging Matters in 2026

Manual cataloging is the bottleneck on most estate sales. AI auction cataloging changes the per-lot economics; see the deeper writeup on AI-powered auction cataloging. Gavelist's triangulation of published cataloging rates puts full-scope manual cataloging at roughly 8 to 15 lots per hour, about 4 to 7.5 minutes per lot. At that pace, one 400-lot estate sale a month means 27 to 50 hours of desk time per sale spent on cataloging alone.

The market around that work is growing. According to Technavio (2026), the global online auction market is forecast to grow by USD 4.25 billion from 2025 to 2030, a 13.6% CAGR. According to Business Research Insights (accessed September 2026), the global online auction market is valued at about USD 24.75 billion in 2026. The software layer is growing more slowly: according to Cognitive Market Research (2026), the global online auction software market is worth $2,928.32 million in 2026 and is projected to reach $4,484.13 million by 2033, a 6.3% CAGR. According to The Insight Partners (2025), the auction software market was US$626.93 million in 2025 and is projected to reach US$973.51 million by 2034, a 5.65% CAGR. The two research firms define the market differently, which is why their totals differ.

Cataloging quality affects hammer prices as well as throughput. An AI tool that reads every photo (backstamps, hallmarks, labels, condition details) can put facts into the description that a single-photo tool never sees.

Head-to-Head Comparison: Seven AI Cataloging Tools

Prices and features as of September 22, 2026, taken from each vendor's own pricing and product pages. Prices change, so confirm on the vendor's site before you commit.

The Proof: Gavelist Production Data Through September 2026

Feature tables are vendor claims. The number a listicle cannot publish is how often real auctioneers export the AI's work without changing it. According to Gavelist production data (jobs from March 20 to September 22, 2026), 96.3% of 58,134 lots exported through Gavelist went out without a client edit to the AI-written title or description, across 339 recorded catalog exports from 41 client accounts. In September 2026 (September 1 to 22), 97.7% of 11,040 exported lots were unedited. A lot counts as edited if the client saved a change to its title or description in Gavelist before exporting. Lots the AI regenerated count as unedited, Tracking at export began on April 16, 2026; 6,290 of the lots come from snapshots backfilled for jobs created between March 20 and April 12.

One figure matters for reading those numbers: Gavelist's largest client supplied 40,877 of the 58,134 lots (70%) and edited very few of them. Excluding that client, 88.2% of the remaining 17,257 lots across 40 accounts went out unedited, and 95.0% of September's 4,932 were. Gavelist's August figure (96.6% of 38,106 lots, through August 14, 2026) came from the same query; the cumulative rate slipped 0.3 points because lots exported since then were edited more often (95.9% unedited).

Throughput is also measured against production. Clean Gavelist description passes of 300+ lots ran at 1,239 to 1,615 lots per 10 minutes when measured on August 14, 2026. Gavelist publishes the rounder, lower figure of 1,000+ lots in about 10 minutes (roughly 6,000 lots per hour). A live acceptance counter, recomputed from the production database every few minutes, runs on the Gavelist homepage.

Tool-by-Tool Deep Dives

Gavelist

What sets it apart: Gavelist reads every photo in a lot together, with no per-lot cap, so backstamps, hallmarks, signatures and condition details that only appear in detail shots make it into the description. According to Bidspirit's auction catalog imaging guide (2024), multi-angle photography (front, back, side, top and unique features, with 360-degree views for 3D objects) is the standard for comprehensive detail visibility. Gavelist processes 1,000+ lots in about 10 minutes, which is roughly 6,000 lots per hour and the highest stated throughput among the tools here that publish a number. Gavelist is platform-independent and takes none of the hammer price: you pay $0.15 per lot to catalog, and Gavelist takes 0% of your auction sales. Bidding platforms charge separately. According to HiBid's published AuctionFlex 360 pricing (2026), auctions with online bidders on HiBid carry a 2% auction fee plus $0.25 per unique bid, capped at $150 per auction, whichever cataloging tool you use. That is a bidding-platform fee, not a cataloging fee. See HiBid AI cataloging: what auctioneers need to know. Gavelist is built in Pittsburgh, PA, and customers get direct access to the founder.

Limitations: Gavelist has no native mobile capture app. The web app works on a phone, but there is no native iOS or Android shutter for in-the-field capture and no barcode scanning. Gavelist is cataloging-only: it does not run your live auction, clerking, invoicing or settlements. If you want one vendor for the whole auction lifecycle, Gavelist is the cataloging layer, not the full platform.

Best for: Estate auctioneers running 200 to 2,000 lots per sale who already use HiBid, LiveAuctioneers, AuctionFlex or Wavebid and want a platform-independent cataloging tool. See the Gavelist auction cataloging software page or the estate sale software page.

AuctionWriter

What sets it apart: AuctionWriter's pricing table lists a free plan of 50 new lots a month. It also has native iPhone, iPad and Android apps with an offline mode, and UPC, EAN and ISBN barcode scanning from the phone camera. AuctionWriter publishes 10 paid tiers plus a custom tier: $99/mo (1,000 lots), $189/mo (2,200), $289/mo (3,500), $489/mo (7,000), $689/mo (11,000), $889/mo (15,000), $1,089/mo (19,000), $1,289/mo (23,000), $1,489/mo (27,000) and $1,689/mo (31,000). Paid tiers include 5 to 50 team seats, and each team member gets their own login with a role. AuctionWriter states that each lot supports up to 30 images and advertises export to 18+ auction platforms. Its site says it was created by Webflare.

Limitations: AuctionWriter does not publish how many of a lot's 30 images the AI reads when it writes a description, so its multi-photo depth cannot be verified either way. It does not publish a lots-per-hour figure.

Best for: Auctioneers cataloging fewer than 50 lots a month, where the free tier covers it; phone-first capture; or high steady volume. Above roughly 9,900 lots a month AuctionWriter's tiers generally cost less than Gavelist's (Gavelist is cheaper again between about 11,000 and 12,100 lots), down to about $0.054 per lot at 31,000 lots. Compare on the Gavelist vs AuctionWriter page.

Estimint

What sets it apart: Estimint is a workflow suite, not just a cataloging tool: consignment agreements (from the $89 Pro plan), live clerking and invoicing (from the $149 Auction Pro plan) and cataloging live in one platform. Estimint's pricing page lists $29/mo for 300 listings (6 photos per item), $89/mo for 1,500 (12 photos), $149/mo Auction Pro for 3,500 (20 photos) and $249/mo Business for 5,000 (20 photos). Auction Pro and Business include 2 team seats, with more at $19 per seat. The free tier covers 200 listings for 30 days with up to 3 photos. Every Estimint plan includes price estimates, and the Pro and Auction plans add one-click CSV export to AuctionFlex, Proxibid, BidWrangler, LiveAuctioneers, HiBid and Invaluable. Estimint's site now describes Quick Add as processing “hundreds of lots per hour”.

Limitations: Estimint caps photos per item by plan, from 3 on the free tier to 20 on the top plans. Because it is a full suite, switching costs are higher: leaving means moving cataloging, clerking and invoicing. Budget for that scenario before adopting.

Best for: Auctioneers without an existing clerking system who want one vendor for intake through invoicing. At full use, Estimint's Auction Pro plan works out to about $0.043 per listing, the lowest per-unit rate among the tiered plans in this comparison; ListerLeo's flat fee goes lower above roughly 2,800 lots a month. See the Gavelist vs Estimint page.

ListerLeo

What sets it apart: ListerLeo, a Vendidit product, is built around inventory rather than photos. It offers mobile barcode scanning (phone camera or Bluetooth scanner), item-to-location and item-to-pallet tracking, pick lists, vendor manifest matching and label printing to Zebra or thermal printers. Its GlobalSKU AI identifies products, writes descriptions, estimates market value and finds stock images. ListerLeo charges a flat $119 a month (month-to-month or a 3-month term) or $109 a month on an annual term, for unlimited items, with each additional team member at $39 a month. ListerLeo exports to HiBid, Proxibid, AuctionZip or custom templates, delivered by FTP, SFTP, Amazon S3 or webhook, and offers a 30-day free trial with no credit card.

Limitations: ListerLeo does not publish a throughput figure or how many photos per lot its AI reads. Its AuctionWriter comparison page is dated July 2026 and is now out of date: it lists AuctionWriter as browser-only with a single shared login and no advertised barcode scanning, all of which AuctionWriter's own site now contradicts.

Best for: Liquidation, returns and warehouse auctions where items carry barcodes and need location tracking. On price, ListerLeo's flat $119 becomes cheaper than Gavelist's Auctioneer plan above about 1,445 lots a month for a single user; below that, Gavelist costs less. See Gavelist vs ListerLeo.

Lot Lingo

What sets it apart: Lot Lingo, from Newbloom AI, is built around exports to K-BID, HiBid, eBay and Whatnot. Lot Lingo's Auction Maker plan is $200 a month with no per-lot fees and no per-seat charges. It offers a 14-day free trial (a card is required at signup) and a $4,999 Auction Business Starter package. Features include barcode separator sheets, voice-to-text lot entry, and one-click export to K-BID, HiBid, eBay and Whatnot. Lot Lingo claims its workflow is “2–5× faster” but does not publish a lots-per-hour figure.

Limitations: Like most tools here, including Gavelist, Lot Lingo delivers HiBid catalogs as a file; its documentation says to import the finished CSV and photos into Auction Flex, which publishes HiBid catalogs. It does not publish how many photos per lot its AI reads.

Best for: K-BID and HiBid sellers with steady volume and several people cataloging. The flat $200 becomes cheaper than every Gavelist plan above about 2,945 lots a month; below that, Gavelist costs less.

Circuit Auction

What sets it apart: Circuit Auction is an all-in-one auction platform for collectibles houses (stamps, coins, fine art, trading cards and more), covering live bidding, CRM, settlement and invoicing. Circuit's AI generates titles, descriptions and condition notes from images and short notes, suggests low and high estimates from recent market results, matches images in bulk, and works in 40+ languages. Circuit Auction publishes its pricing: the Standard plan is $250 a month on an annual commitment or $350 a month without, plus a 2% commission on winning bids placed through its online platform. AI catalog creation is a $250-a-month add-on, and a fully featured Standard plan reaches $675 a month on the annual rate. Enterprise is a custom fixed price with no commission.

Limitations: Circuit's AI is an add-on to the Circuit platform rather than a standalone cataloging tool, so it suits houses moving their whole operation onto Circuit. The 2% commission on winning bids scales with your sales, unlike a per-lot or flat cataloging fee.

Best for: Collectibles auction houses ready to consolidate onto one platform.

Bidsquare Cloud

What sets it apart: Bidsquare Cloud is Bidsquare's inventory and auction management software. When Bidsquare announced its auction AI in January 2025, it said the AI generates item titles, low and high estimates, descriptions, condition notes and categories from images. Bidsquare Cloud says it is designed to support any category, lists multichannel management across third-party platforms and data ownership on its plans page, and includes a custom-branded iOS and Android app on every plan.

Limitations: Bidsquare Cloud does not publish prices; its plans are tiered by events per year, and you contact sales. Its current product pages do not detail the AI cataloging feature beyond the January 2025 announcement, so test it directly before relying on it.

Best for: Auction houses that want Bidsquare's management software, events-based plans and a branded mobile app, and are comfortable with quote-based pricing.

What Changed in September 2026

• Two tools added. ListerLeo ($119/mo flat, unlimited items, barcode and warehouse workflow) and Lot Lingo ($200/mo flat, K-BID and HiBid exports) now appear in the comparison.
• Circuit Auction's pricing corrected. The previous version of this guide said “contact sales”. Circuit's pricing page lists $250 to $350 a month plus a 2% commission on winning bids, and AI cataloging as a $250-a-month add-on.
• Estimint changed its speed claim. The old claim of “50+ lots per hour” no longer appears on Estimint's site, which now says Quick Add processes “hundreds of lots per hour”. Its prices ($29 to $249 a month) are unchanged.
• AuctionWriter re-verified. Its 10 paid tiers are unchanged ($99 to $1,689 a month); an earlier version of this guide miscounted them as 11. This guide now also lists what AuctionWriter's site states about team seats per tier (5 to 50 on paid tiers), individual logins with roles, native iPhone, iPad and Android apps with offline mode, and barcode scanning.
• Bidsquare Cloud corrected. Its AI cataloging was announced in January 2025, not 2026 as an earlier version of this guide said, and it is not limited to fine art or to Bidsquare's marketplace.
• Gavel Buddy's domain now redirects. As of September 22, 2026, gavelbuddy.com redirects to an Auction Flex trial page. See Gavel Buddy alternatives.
• Gavelist production data extended. This guide previously quoted older acceptance figures (30,850 lots, over 99% accepted). It now uses Gavelist's export measurement, run through September 22 (96.3% of 58,134 lots; 88.2% excluding the largest client), with the method and client concentration stated. One throughput figure, 1,000+ lots in about 10 minutes (roughly 6,000 lots per hour), is now used throughout; an earlier version also said “over 5,000 lots per hour” in one table.
• Market data refreshed to Technavio's 2026 edition (USD 4.25 billion of growth, 2025 to 2030) and Cognitive Market Research's 2026 figures.

What to Look for in AI Cataloging Software

Feature lists are easy to write. The differences that matter at month 18, when you have cataloged 20,000 lots and want to migrate, are subtler. These are the eight criteria from Gavelist's earlier evaluation guides.

1. Multi-photo vs single-photo analysis

If the AI reads only one photo per lot, the description reflects only what is in that photo. The backstamp that identifies a Rookwood vase as a signed Kataro Shirayamadani piece is on the bottom. The hallmark that distinguishes sterling from plate is inside the clasp. The chip on the rim is the condition note that explains a $20 hammer instead of $200. A single-photo AI cannot see them, so it cannot write them. Ask each vendor how many photos per lot the AI actually reads, not just how many you can upload. See single-photo vs multi-photo AI cataloging for the side-by-side breakdown.

2. Platform export breadth

If you already use HiBid, AuctionFlex, LiveAuctioneers, K-BID or Wavebid, your cataloging tool needs to export cleanly to that platform. “Compatible with all popular platforms” without a specific integration list is a yellow flag. Ask for the exact CSV column mapping, or test on a real sale before committing. Also ask whether an export goes straight to the platform or through an intermediate system, as Lot Lingo's HiBid files do through Auction Flex. See the HiBid integration, LiveAuctioneers integration, and AI software that exports to HiBid. For the cross-platform workflow, see how to list one auction on multiple platforms.

3. Transparent pricing

Published per-lot or per-month pricing lets you forecast costs. Six of the seven tools here now publish prices; Bidsquare Cloud is the exception. Compare pricing models, not just headline prices: per lot (Gavelist), monthly lot tiers (AuctionWriter, Estimint), flat unlimited (ListerLeo, Lot Lingo), or platform fee plus commission (Circuit Auction). Your baseline is the manual rate: Sound Auction Service's published $3.00 per lot for full lot preparation. Anything you pay for AI should be measurably below it.

4. Speed at your sale size

“Lots per hour” claims are marketing numbers unless the vendor says how they were measured. Only two tools in this comparison publish a throughput figure: Gavelist (1,000+ lots in about 10 minutes, measured against production) and Estimint (“hundreds of lots per hour”). Lot Lingo says “2–5× faster” without a baseline. The metric that matters is wall-clock time from finishing photography to lots queued for export. Test with a real 100-lot batch on a free trial before signing a monthly contract. Against Gavelist's baseline of 8 to 15 lots per hour for full manual cataloging, any AI tool should be clearly faster.

5. Workflow fit: standalone tool vs full suite

A standalone cataloging tool drops into whatever auction stack you already run. A full suite (cataloging, clerking, invoicing and bidding) means moving your whole operation onto the vendor's platform. Suites have higher switching costs in both directions: easier to adopt from scratch, harder to leave at month 24. See the real cost of bundled auction software for the trade-offs.

6. Value intelligence (estimates and condition reports)

Most tools here now produce estimates and condition notes automatically, but quality varies. Test on items where you already know the answer, such as a piece you sold last quarter, a hallmark you can verify, or a condition issue you have already assessed, before trusting the output on unknowns. See AI that tells you what an item is worth from a photo for how an estimate is generated.

7. Data portability: can you leave?

Whatever tool you choose, you will eventually evaluate the next one. Ask before signing: can you export your full lot history as a structured file (CSV or JSON) without a manual scrape? If the answer is “contact support”, you have lost portability. Standalone cataloging tools usually beat full suites here. See platform-independent AI cataloging for the reasoning.

8. Track record and company focus

How long has the team built auction software specifically? Is auctioneering the company's main focus or one of several verticals? Ask before you commit to a multi-year workflow.

How to Choose the Right Tool

A short decision tree based on the criteria above:

• Choose Gavelist if you run estate or general-merchandise auctions, already use HiBid, LiveAuctioneers, AuctionFlex or Wavebid, want every photo per lot read together, and want per-lot pricing with 0% of sales. See Gavelist pricing or the small auctioneer cataloging guide.
• Choose AuctionWriter if you run fewer than 50 lots a month (free tier), want native phone and tablet apps, or catalog at steady volume above roughly 9,900 lots a month.
• Choose Estimint if you have no clerking system and want one vendor for intake, cataloging, clerking and invoicing (Auction Pro, $149 a month and up).
• Choose ListerLeo if your inventory is barcoded or manifested (returns, liquidation, warehouse) and you need location and pallet tracking.
• Choose Lot Lingo if you sell mainly on K-BID or HiBid and several people catalog at steady volume.
• Choose Circuit Auction if you run a collectibles house and want to consolidate onto one platform, and a commission on winning bids fits your model.
• Choose Bidsquare Cloud if you want events-based auction management with a branded mobile app and are comfortable with quote-based pricing.

What Does AI Cataloging Cost Per Lot?

According to Sound Auction Service in Washington state (accessed September 2026), its cataloging rate is $3.00 per lot for full lot preparation, including photography, description and upload. That is the manual baseline. The table below shows each tool's published price as an effective cost per lot at a stated volume.

Per-lot cost depends on your volume and on whether you fill a tier. At 1,000 lots a month, the gap between $79 and $99 is $20. What usually matters more is speed to live (when bidders can see the catalog) and description quality (whether bids reflect what you have). See high-volume auction photo processing for the speed argument in detail.

Frequently Asked Questions

What is the best AI auction cataloging software in 2026?
It depends on your inventory and platform stack. For estate and general-merchandise sales where marks and labels matter, Gavelist reads every photo in a lot together, processes 1,000+ lots in about 10 minutes, and costs $0.15 per lot pay-as-you-go. For a full workflow including consignment and clerking, Estimint's Auction Pro plan is $149 a month. For barcoded inventory, ListerLeo is $119 a month flat. For description-writing tools specifically, see the best AI auction description software.

What is the fastest AI auction cataloging software?
Gavelist publishes the fastest stated throughput in this comparison: 1,000+ lots in about 10 minutes, roughly 6,000 lots per hour, measured on clean production runs at 1,239 to 1,615 lots per 10 minutes. Estimint states “hundreds of lots per hour”; AuctionWriter, ListerLeo, Lot Lingo, Circuit Auction and Bidsquare Cloud do not publish a lots-per-hour figure.

What are AuctionWriter alternatives in 2026?
The main AuctionWriter alternatives are Gavelist ($0.15/lot pay-as-you-go, every photo per lot read together, built in Pittsburgh, PA), Estimint ($29 to $249/month; clerking and invoicing from $149), ListerLeo ($119/month flat, barcode and warehouse workflow), Lot Lingo ($200/month flat, K-BID and HiBid exports), Circuit Auction (collectibles all-in-one, AI as a $250/month add-on), and Bidsquare Cloud (events-based auction management, pricing by quote). If you are already on HiBid, see HiBid's own AI cataloging. HiBid lists a 2% auction fee on auctions with online bidders (AuctionFlex 360 pricing, 2026) whichever cataloging tool you use; Gavelist's own charge is per lot and takes 0% of your auction sales.

Can I use AI cataloging software with HiBid?
Yes. Gavelist exports ready-made files for HiBid, LiveAuctioneers, Proxibid and BidWrangler, plus a universal CSV/XLS formatted for import by AuctionZip, AuctionMethod, Wavebid, AuctionFlex 360 and any other spreadsheet-import platform. AuctionWriter, Estimint (Pro and above), ListerLeo and Lot Lingo also list HiBid exports; Lot Lingo's HiBid file is imported through Auction Flex. Circuit Auction and Bidsquare Cloud are full auction-management platforms. See the Gavelist HiBid integration page and the LiveAuctioneers integration page.

Is there free AI auction cataloging software?
AuctionWriter's pricing table lists a free plan of 50 new lots a month (its page does not make clear whether that allowance recurs indefinitely). Estimint's free plan covers 200 listings for 30 days. ListerLeo offers a 30-day free trial with no credit card, and Lot Lingo a 14-day trial with a card required. Gavelist's first 100 lots are free with no card (good for 30 days from the first described lot), then pay-as-you-go at $0.15 per lot with no monthly minimum, so a 30-lot sale costs $4.50. Circuit Auction and Bidsquare Cloud do not publish free options.

Does AI cataloging work for all auction types?
For general merchandise, estate, household, tools, sporting goods and decorative arts, yes: modern AI cataloging handles these reliably. For specialist categories (high-end fine art, rare coins, signed first editions, autographs), AI produces a strong first draft but specialist verification is still required. See the estate sale AI tool guide and the how to catalog an estate sale guide.

How accurate are AI auction descriptions?
Accuracy depends on photo quality and how many photos the AI reads. In Gavelist production data, 96.3% of 58,134 lots from jobs between March 20 and September 22, 2026 went out without a client edit to the AI-written title or description; excluding Gavelist's largest client, which supplied 70% of those lots, the figure is 88.2%. Multi-photo tools that read backstamps, hallmarks and condition details do better on collectible and specialty items; for commodity items, single-photo tools produce adequate descriptions. See how to write auction descriptions with AI and how to photograph estate sale items for maximum bids.

What is the cheapest way to catalog auction lots?
At scale, AI cataloging costs a fraction of manual work: Sound Auction Service's published manual rate is $3.00 per lot, while Gavelist's pay-as-you-go price is $0.15 per lot with no monthly minimum. The $3.00 also covers photography and upload, so the saving applies to the description work, not the whole job. For very low volume, AuctionWriter's 50 free lots a month is the cheapest entry. At 1,000 lots a month, Gavelist's Auctioneer plan is about $0.079 per lot. Gavelist is not the floor at every volume. At full use, AuctionWriter's top tier reaches about $0.054 per lot and Estimint Auction Pro about $0.043 per listing. Flat-fee tools get cheaper as volume rises: ListerLeo's $119 costs less than Gavelist's Auctioneer plan above about 1,445 lots a month, and Lot Lingo's $200 costs less than any Gavelist plan above about 2,945. Gavelist's advantage is under-utilization: you never pay for a tier you do not fill. See the cheapest way to catalog auction lots.

What is the best auction cataloging software for small auctioneers?
Small auctioneers cataloging under 200 lots a month should favor pay-as-you-go over subscriptions. Gavelist's $0.15/lot pay-as-you-go has no minimum commitment, so 200 lots cost $30. AuctionWriter's free 50 lots a month suits very low volume. See our guide to AI cataloging for solo auctioneers.

Does Gavelist take a percentage of my auction sales?
No. Gavelist charges a flat $0.15 per lot to catalog and takes none of the hammer price. The bidding platform you sell on may still charge its own fees: according to HiBid's published AuctionFlex 360 pricing (2026), auctions with online bidders on HiBid carry a 2% auction fee plus $0.25 per unique bid (capped at $150 per auction), whichever cataloging tool you use. That is a bidding-platform fee, separate from cataloging. For the full breakdown, see does HiBid charge a percentage of sales. Because Gavelist is not a marketplace, it has no per-sale fee: you catalog once and sell wherever you choose.
