Bidders do not all gather in one place. Some follow LiveAuctioneers, some bid on HiBid, equipment buyers watch Proxibid, and others shop eBay, so reaching the full pool of buyers usually means listing the same auction in several places. The catch is that re-cataloging the same lots for each marketplace is the slowest part of the job, and it scales badly the more platforms you add.
The pull toward wider reach is real. According to Technavio (2025), the global online auction market is projected to grow by USD 3.98 billion from 2025 to 2029, at a CAGR of approximately 14%. According to Business Research Insights (2025), the global online auction market is valued at approximately USD 24.75 billion in 2026. A larger, more distributed market is exactly the case for listing in more than one place.
This guide is the workflow: catalog the auction once in Gavelist, export a file for each platform, and list everywhere, without re-keying. It is the how-to companion to the why; the case for not locking into a single vendor is laid out separately in our analysis of platform-independent cataloging. If you are still choosing a cataloging tool, our best AI cataloging software comparison covers the options.
Why list on more than one platform
The short version is reach: different marketplaces carry different bidder audiences, and listing across several puts each lot in front of more potential buyers. Hybrid and online selling has been pulling volume upward as well. According to EstateSales.net (2024), hybrid online and in-person sales saw a 50% increase in sales volume. The deeper argument about avoiding vendor lock-in is covered in that analysis; this guide stays on the mechanics of doing it.
The old way vs the catalog-once way
The difference between re-keying per platform and cataloging once shows up in time, reach, and cost. According to Estimint's cataloging analysis (2025), manual cataloging of a 200-lot sale takes 46 to 64 hours, roughly 14 to 19 minutes per lot including photography, description writing, and data entry, and that cost repeats for each marketplace listed the old way. According to AuctionMethod's 2026 Retail Liquidation Auction Industry report, manual cataloging benchmarks run from 20 to 40+ lots listed per employee-hour, with labor costs of $0.50 to $3.00 per lot.
| Approach | Cataloging effort | Where it can list | Sales cut |
|---|---|---|---|
| Re-key per platform | Re-catalog each marketplace separately (hours per 200 lots, per platform) | One platform per pass | Each marketplace's own fees |
| Catalog once, export many (Gavelist) | One pass (about 1,000 lots in ~10 min) | 10+ platforms from one catalog | 0% from Gavelist (keep 100% of hammer) |
Step 1: Catalog the auction once
Upload your lot photos to Gavelist. In a single cataloging pass, Gavelist generates the title, description, category, and value estimate for each lot from the images, so you are editing generated drafts rather than writing every field from scratch. On the description pass, Gavelist catalogs about 1,000 lots in roughly 10 minutes, about 6,000 lots per hour, running 8 concurrent workers. This one pass is the only time you catalog the auction, no matter how many platforms it eventually lists on.
Step 2: Export a file for each platform
From the single catalog, Gavelist produces platform-formatted exports with the columns pre-mapped to each platform's catalog fields. The same catalog can be written out for 10+ platforms. Confirmed export formats include:
- LiveAuctioneers
- HiBid
- Proxibid
- eBay
- A generic CSV for any other platform that accepts a spreadsheet import
Each export is the same catalog in a different format, so there is no re-keying between platforms. You catalog once and generate as many platform files as the sale needs.
Step 3: Upload each file to its platform
For each platform, import its export through that platform's catalog or seller tools into the event you set up there. The destination steps differ by platform, but the principle is the same: each file is already formatted for its target, so the import is an upload rather than a reformatting job. Do not expect a single universal upload; each marketplace ingests its own file on its own side.
The per-platform details live in the deep-dive guides: how to export auction lots to LiveAuctioneers, how to export auction lots to Proxibid, and HiBid CSV imports.
What it costs to catalog once vs per platform
Cataloging once changes the cost structure as well as the workflow. Gavelist charges a flat per-lot cataloging price and takes 0% of your auction sales, so you keep 100% of the hammer. Pricing is published: pay-as-you-go at $0.15 per lot, or monthly tiers: Auctioneer at $79 per month (up to 1,000 lots), Pro at $160 per month (up to 2,500 lots), and Enterprise at $250 per month (up to 5,000 lots). You pay to catalog the auction once, not once per platform.
That is different from paying a percentage of sales on a marketplace. HiBid (AuctionFlex 360), for example, charges an online bidding fee of 2% of gross auction proceeds. That is a bidding-platform fee on sales, not a cataloging fee; the contrast is a marketplace that takes a cut of what you sell, versus a cataloging tool that takes 0% and lets you export the same catalog to every platform.
Keeping descriptions and value estimates consistent across platforms
Because the catalog is generated once, the same title, description, and value estimate flow to every export, so a lot reads the same on LiveAuctioneers as it does on Proxibid or HiBid. There is no drift from re-typing a description slightly differently on each site.
The value estimate is an optional add-on: a value tier plus an approximate low-and-high dollar range grounded in real sold prices rather than asking prices. It is not a certified appraisal, so treat it as a likely, approximate range. When it is included, the same estimate carries across every platform, which keeps reserves and descriptions aligned wherever the lot is listed.
Frequently Asked Questions
Can I list the same auction on LiveAuctioneers, HiBid, and Proxibid at once?
Yes. You catalog the auction once in Gavelist and export a separate platform-formatted file for each marketplace, so the same sale can be listed on LiveAuctioneers, HiBid, and Proxibid from a single cataloging pass.
Do I have to re-catalog my lots for each platform?
No. The catalog is generated one time, and Gavelist produces a pre-mapped export for each of 10+ platforms from that single catalog, so there is no re-keying between marketplaces.
Does Gavelist take a percentage of sales on any platform?
No. Gavelist charges a flat per-lot cataloging price and takes 0% of auction sales, so you keep 100% of the hammer on every platform. Any sales fees belong to the individual marketplaces and are set by them.
Will my descriptions and estimates match across platforms?
Yes. Because each platform file comes from the same catalog, the same title, description, and value estimate go to every platform, so listings stay consistent wherever the lot runs.
