There are dozens of different types of auctions running every day — from car dealers clearing aged inventory to nonprofits raising funds at annual galas, from farm retirement sales to estate liquidations, from wine collector auctions to abandoned storage units. This directory maps every major and niche auction category Selling Lane supports, with links to detailed guides for each type.
Whether you're researching which format fits your business or you're a bidder trying to understand how different auctions work, start with the category that matches what you sell — each linked guide covers the typical workflow, fee structure, and real revenue economics for that vertical.
The Three Core Auction Formats
Before picking a category, it helps to understand how auctions are run. Every auction type in this directory uses one or more of these three formats:
- Live auctions — A licensed auctioneer calls bids in real time, either in a physical ring or via simulcast to online bidders. Best for high-energy sales — estate auctions, livestock, production horse sales, farm retirements.
- Timed online auctions — Lots open for 3–10 days with automated proxy bidding and anti-sniping extensions. Best for consignment stores, pawn shops, used-furniture resellers, and lower-touch inventory.
- Silent auctions — Sealed-bid bidding within a fixed window, often at a charity event. Best for galas, school fundraisers, and benefit events.
Selling Lane supports all three formats on every plan — see the full feature list.

How to Pick the Right Category
If your inventory doesn't match any of the categories above exactly, pick the closest match by workflow rather than by item type:
- Single unique lots? Use the estate sale auction workflow — catalog each piece individually with unlimited photos and a condition report.
- High-value serialized equipment? Use the farm & heavy equipment workflow with hours, PTO, serial, and inspection-report fields.
- Live animals? Use the horse auction template (pedigree fields, video per lot, simulcast ringside) even for other species — the fields adapt.
- Fundraising event? See charity auction software for silent + live + paddle-raise workflows on one platform.
- Aged retail inventory? See pawn shop auction software for weekly recovery auctions with mixed single-lot inventory.
- Local-pickup-only merchandise? See used furniture auction software for self-serve pickup window booking and consignor settlements.
Frequently Asked Questions About Auction Categories
What are the main types of auctions?
The three main auction formats are live auctions (run in real time by a licensed auctioneer), timed online auctions (lots open for 3–10 days with proxy bidding), and silent auctions (sealed bids within a fixed window). Every auction category in this directory uses one or more of these formats.
What is the most common type of auction?
Timed online auctions are now the most common format for US commercial auctioneers, thanks to low overhead and remote-bidder reach. Live auctions still dominate high-value verticals like sport-horse production sales, real estate, and flagship estate liquidations — where ringside energy drives higher final prices.
Can one auction platform run all these auction types?
Yes. Selling Lane supports every format (live, timed, silent) and every category in this directory on a single flat-fee subscription — no per-category pricing, no per-event fee, no commission on hammer. See pricing →
Do I need a different license to run different auction categories?
Most US states license auctioneers generically, not by category. However, certain verticals — real estate, firearms, livestock, cannabis — may require additional state or federal registrations. Check with your state's auctioneer commission before running your first auction in those categories.
What's the difference between an auction category and an auction format?
The category describes what you're selling (cars, estates, horses, charity gala items). The format describes how the auction is run (live, timed online, silent). A single category can use any of the three formats — for example, a charity can run a silent auction, a live auction, or a timed online auction to raise funds.
