Auction Cataloging Software Compared: 2026 Edition

Short answer: the six auction cataloging options most worth comparing in 2026 — Gavelist, AuctionWriter, Estimint, Circuit Auction AI, Bidsquare Cloud, and HiBid's AuctionFlex 360 — split cleanly by pricing model (per-lot, monthly-tier, or bundled platform) and by whether they charge anything on your actual sales. Below is the full comparison, with real published prices where vendors publish them and honest notes where they don't.

The comparison at a glance

Reading the pricing models

Per-lot (Gavelist). A flat $0.15 per lot with no monthly minimum. You pay for what you catalog: 300 lots is $45, 1,000 lots is $150. Best fit when volume swings month to month, because there's no tier to fill or outgrow.

Monthly tiers (AuctionWriter, Estimint). According to AuctionWriter's published pricing, plans run free for 50 lots/month, $99/month up to 1,000 lots, and $189/month up to 2,200. Estimint runs a free trial, then $29/month for 300 listings and $89/month for 1,500. Predictable when volume is steady and lands inside a tier; less efficient when it doesn't.

Bundled platform (Circuit Auction AI, Bidsquare Cloud). Cataloging comes as one feature of a full auction platform with CRM, invoicing, and live bidding. Circuit Auction AI bundles AI cataloging into its all-in-one system; Bidsquare Cloud includes native AI cataloging. Neither publishes standalone cataloging pricing, because cataloging isn't sold separately — you're buying the platform.

The throughput column

Price only matters if the tool keeps up on sale week. The baseline is manual: according to AIM (2025), hand-cataloging runs 15–25 lots per hour at $14–$28/hour, and according to Estimint's cataloging analysis, a 200-lot estate sale takes 46–64 hours end to end. Against that, Gavelist processes 500 lots in about 10 minutes from photos to export-ready listings, with value estimates and market comparables included in the same pass. Platform-native cataloging (Circuit, Bidsquare, HiBid) runs inside each system; throughput varies by product.

The sales-fee column — read this one carefully

The most important distinction in the table isn't price, it's whether a tool charges on your sales. HiBid's AuctionFlex 360 charges an online bidding fee of 2% of gross auction proceeds — a bidding-platform fee, not a cataloging fee. On a $50,000 auction that's $1,000, and it's independent of how the lots were cataloged. Bundled platforms similarly fold their economics into platform terms. A per-lot or per-month cataloging price is a fundamentally different number from a percentage of your hammer total — the $0.15/lot cataloging fee and the 2% bidding fee aren't comparable — and Gavelist takes 0% of auction sales. When you compare, compare like line items.

The exports column

Standalone cataloging tools produce files that load elsewhere; platform-native cataloging keeps the catalog inside the platform. Gavelist exports to HiBid, LiveAuctioneers, AuctionZip, and Proxibid, so you catalog once and list on whichever marketplace a sale uses. Circuit, Bidsquare, and HiBid catalog into their own systems — coherent if you run everything on one platform, a lock-in if you don't.

Bottom line

Pick by pricing model first. If your volume swings, per-lot pricing fits. If it's steady and fits a tier, monthly plans are predictable. If you want one vendor for your whole back office, a bundled platform is the coherent choice — evaluate it on CRM and invoicing, since that's what you're really buying. And across all of them, keep the cataloging cost separate from any percentage-of-sales platform fee. They're different numbers, and confusing them is the easiest comparison mistake to make.
