Auction terms and glossary for buyers and sellers

Use this glossary to understand common terms, then read the live catalog because a platform or auction may define a rule more specifically.

Ask earlyWhen a definition affects a bid

Auction language can compress a lot of responsibility into a short phrase. ‘As is,’ ‘buyer’s premium,’ ‘reserve,’ and ‘soft close’ can each change how a person evaluates a lot or plans a sale.

These definitions explain common usage, not a universal legal definition for every jurisdiction, platform, or event. When the live catalog defines a term or rule, that event-specific language controls.

Practical checklist

Five terms every bidder should find before bidding

You do not need to memorize the glossary. You do need to locate the rules that change your total, timing, and ability to receive the property.

Buyer’s premium: the percentage or fee added to the hammer price
Soft close or extension: whether a late bid adds time to a lot
Payment terms: when and how a winning invoice must be paid
Pickup and shipping: location, appointment, removal, packing, and carrier responsibilities
As is, where is: the condition and location framework under which the property is offered

Step by step

How to use an auction term in context

A definition is most useful when you connect it to the exact lot, event, and platform rule.

Find the term
Look in the event overview, terms, lot description, platform help, invoice, or fulfillment instructions—not only promotional material.
Read the event definition
If the live terms explain the rule, use that language. A general glossary cannot override the specific auction agreement.
Apply it to your decision
Calculate how the term changes price, timing, condition risk, payment, removal, shipping, seller responsibility, or bidder responsibility.
Ask before acting
If the answer would change your bid or decision to consign, ask while there is time for a clear response.

Buyer vocabulary

Price and bidding terms

The hammer price is not always the final invoice total, and the amount displayed during bidding may not show the bidder’s confidential maximum. Understanding the pricing words keeps the decision tied to the complete cost.

Seller vocabulary

Consignment and settlement terms

Seller terms define authority, accepted property, fees, reserves if any, expenses, withdrawals, reporting, unsold property, and when net proceeds are settled. Those terms belong in the written engagement, not assumption.

Fulfillment vocabulary

Possession, pickup, and shipping terms

A paid invoice does not by itself put the lot in a buyer’s vehicle or carrier network. Pickup windows, loading responsibility, packaging, shipping approval, freight access, and removal deadlines may each have separate rules.

Plain-language reference

Common auction terms

Use the definition for orientation, then confirm the exact rule in the live event terms or written engagement.

Absentee bid: A bid submitted before or without participating in the live closing. On many online platforms, a maximum bid performs this function.
As is, where is: Property is offered in its present condition and location, subject to the specific inspection, warranty, removal, and other language in the auction terms.
Bid increment: The minimum amount by which the current bid advances. The platform or auction terms determine the increment schedule.
Bidder registration: The event-specific process of providing required information, accepting terms, and receiving approval to bid.
Buyer’s premium: A percentage or fee added to the hammer price and paid by the winning buyer. Applicable tax and fulfillment may also be added or charged separately.
Catalog: The organized auction record containing lots, photographs, descriptions, terms, schedule, and bidding access.
Consignment: An arrangement in which an authorized owner or representative places property with an auction company to sell under a written agreement.
Estimate: A planning range or opinion, when provided, rather than a guaranteed hammer price, appraisal conclusion, or offer to buy.
Hammer price: The winning bid amount before the buyer’s premium, applicable tax, shipping, or other charges described in the auction terms.
Lot: One item or a group of items offered together under one lot number and one winning bid.
Maximum bid: The highest amount a bidder authorizes a platform to bid on the bidder’s behalf, normally advanced in increments as competition requires.
No reserve or absolute: Common terms for property intended to sell without a minimum reserve, subject to the exact event language and applicable law.
Online-only auction: An auction in which bidding occurs through an online platform rather than in a physical live auction room.
Pickup window: The published or scheduled period in which a paid buyer may collect property under the location, loading, identification, and removal rules.
Provenance: Documented ownership or custody history. A story, attribution, or prior listing is not automatically verified provenance.
Reserve: A confidential or stated minimum condition under which property may be sold, if used and permitted by the agreement and auction terms.
Seller’s commission: Compensation paid from the seller side under the consignment agreement, often expressed as a percentage, fee, or engagement-specific structure.
Settlement: The post-sale accounting and payment to the seller under the consignment agreement after required reconciliation, collections, fees, expenses, and exceptions.
Soft close or bid extension: A rule that adds time to a lot when a bid arrives within a defined final window, allowing active bidders an opportunity to respond.
Staggered closing: A schedule in which lots begin closing in groups or at intervals rather than all ending at the same moment.
Withdrawal: Removal of property from the auction process. The consignment agreement and auction terms may limit when or why this can occur and who bears resulting costs.

Pause before proceeding

Common trouble spots

A clear pause is usually cheaper than repairing a catalog, ownership, condition, privacy, safety, or logistics problem later.

Assuming a familiar term carries the same rule in every auction
Treating hammer price as the complete buyer total
Treating an estimate, asking price, or old appraisal as a guaranteed result
Using ‘as is’ as a substitute for reading the description, photos, inspection terms, and known disclosures

Questions and answers

What people ask next

For a specific event or engagement, use the live catalog, written terms, agreement, and direct response from the responsible person.

Do all auction companies use these terms the same way?

No. These are common explanations. The live event terms, applicable law, and platform instructions may define or apply a term more specifically.

Is the hammer price my final total?

Usually not. The invoice may add the buyer’s premium and applicable tax. Pickup costs, packing, shipping, freight, or other auction-specific charges may also apply or be billed separately.

Does ‘as is’ mean the description can be inaccurate?

No. The auction catalog should communicate known and visible information responsibly. Buyers still need to inspect all photographs, read the full description and terms, and ask material questions before bidding.

Where should I look when two explanations differ?

Start with the live catalog and event-specific terms, then the current platform instructions. Ask the auction company before bidding or signing an engagement if the difference affects your decision.

Put the definition to work

Use the glossary beside the live auction terms

General definitions build confidence. The current catalog and platform provide the exact dates, premium, closing rule, payment instructions, and fulfillment terms for an event.
