Hold the affected lot
Pause invoice finalization, payment collection, seller settlement and property release for that lot where those steps have not already completed.
Use this field procedure when the accepted bidder is known, but an incorrect hammer price appears in the clerking or sale record.
Hold downstream processing, preserve the original entry, prove the accepted amount from independent evidence, then make one authorized correction and reconcile every record that depends on the hammer price.

The immediate problem is not only the number in the clerk screen. The hammer price can feed buyer premium, tax, invoice totals, payment requests, seller settlement and release paperwork. Contain those downstream steps before correcting anything.
Pause invoice finalization, payment collection, seller settlement and property release for that lot where those steps have not already completed.
Capture the lot number, recorded bidder, recorded hammer price, time, bid source and visible event history before an edit changes what staff can see.
Make sure this is actually a price-entry error. If the buyer is also uncertain, stop using this runbook as a simple clerical correction.
Record the amount currently in the system and the amount believed to have been accepted. Do not overwrite one with the other from memory.
Save the clerking history, online bid log, room recording, auctioneer notes, spotter notes or other contemporaneous record that can establish the accepted bid.
One person prepares the correction; an auctioneer, manager or other designated authority confirms the outcome before the primary sale record is changed.
These incidents can look similar on an invoice but require different recovery paths. This page covers a proven buyer with an incorrectly recorded hammer amount.
The accepted bidder is established, but the amount recorded in the primary sale record does not match the accepted bid.
If the sold amount is right but the lot was assigned to the wrong bidder number, use the Wrong Bidder Number correction runbook.
A floor bid may have been tagged as online, phone or absentee even though buyer and amount are otherwise correct. Correct source only after the event sequence is verified.
That is no longer a routine data-entry fix. Preserve the evidence and escalate the sale-status decision instead of forcing a convenient value into the record.
A value can look wrong when staff are comparing two different price bases. This matters most for quantity, Times-the-Money and grouped-lot sales, where a clerk screen may show a unit hammer while an invoice or report shows an extended total.
Write the price basis beside the proposed correction before anyone edits the sale record. If the system stores a unit amount, do not replace it with the multiplied total merely because the total is larger.
The hammer price belongs in the primary sale record. Buyer premium, tax, invoice balance and seller settlement are downstream calculations or records. If staff repair only the invoice, the auction can end with two conflicting truths: one amount in clerking and another amount in accounting.
Keep the buyer unchanged when bidder identity is proven. Establish the accepted amount, correct the primary record through the supported workflow, then re-check everything that derives from that amount.
Lot, accepted bidder, accepted amount, bid source and sale status form the core record to verify first.
Any charge derived from hammer price must be recalculated from the corrected result rather than manually patched.
Void, supersede or regenerate affected buyer documents through the supported workflow and preserve payment history.
Check consignor proceeds, commission calculations, sale totals, exports and management reports for the corrected amount.
The correction fixes today’s lot. The cause tells you whether the same error could already exist elsewhere in the sale.
Room noise, overlapping bids, rapid increments or a distant auctioneer can turn a correctly accepted bid into a wrongly typed amount.
A dropped digit, transposed number or extra zero can create a plausible-looking amount that is still materially wrong.
The clerk may record the prior bid rather than the accepted bid, especially when the auctioneer advances quickly or restarts the cadence.
The visible online event and the auctioneer’s floor acknowledgement may be close enough that staff record the wrong amount or sequence.
A post-hammer catalog or clerking edit can replace a correct amount if the operator is working on the wrong lot or field.
When results move between systems, a stale value, mapping problem or later overwrite can make the final sale record differ from the live event history.
A wrong hammer amount discovered seconds after the call may need one controlled edit. The same error found after payment, settlement or property release becomes an accounting, authority and audit problem as well. The targets below are operational priorities, not universal legal deadlines; published sale terms and applicable rules control.
| State when found | Operational target | Immediate control | Correction scope | Release condition |
|---|---|---|---|---|
| Clerked; invoice not generated | Immediate — resolve before invoicing resumes. | Hold the lot result. | Verify accepted amount, confirm correction authority, amend the primary sale record and check premium/tax preview. | Lot, bidder, amount and source agree. |
| Invoice generated or emailed | Same business day where practical; before payment or release continues. | Stop payment and release. | Correct sale record first, then void or supersede the wrong invoice and issue one replacement. | Only the corrected invoice remains active. |
| Payment already applied | Immediate management/accounting review; do not wait for normal post-sale cleanup. | Preserve payment history; stop further processing. | Confirm authority, correct the sale record and invoice, then handle any balance or refund under normal payment controls. | Payment and receipt records match the corrected balance. |
| Seller settlement prepared or paid | Same business day management/accounting escalation. | Freeze affected settlement changes. | Reconcile proceeds, commission, tax, reports and any prior remittance with management/accounting oversight. | Buyer and seller sides agree with the corrected sale result. |
| Property already released | Immediate management escalation and documented review. | Preserve all documents, communications and transaction history. | Treat as a late financial/contract exception: establish the corrected amount, review the applicable sale terms and authority, contact the buyer in writing, and involve accounting or legal review where the change is material or disputed. | No further release step remains; close only after the financial and audit exception has a documented outcome. |
Do not treat a released lot as another routine clerk edit. Preserve the original invoice, payment, release record and supporting evidence; confirm the corrected hammer and resulting balance; identify the Terms or Conditions provision and internal authority being relied on; then route buyer communication and any financial remedy through management. Do not automatically charge a payment method, withhold unrelated property, restrict a bidder account or start collection activity unless the auction house’s terms, internal authority and applicable law permit that action.
Small auction houses often have thin staffing. Separate the decisions even when the same people wear multiple hats.
Identify the lot, save the original record, state exactly what appears wrong and gather the clerking history. Do not manufacture certainty from memory.
Where the event can be established, confirm what bid was acknowledged and whether the matter is a clerical error or a disputed sale result.
Control invoice replacement, payment adjustments, seller settlement and communication when the error has moved beyond clerking.
A second person compares the corrected lot, invoice, payment and settlement records against the evidence before the incident is closed.
If the clerk is also the cashier or manager, create a deliberate pause before the edit. Read the evidence, write the proposed original and corrected values, obtain the auctioneer’s confirmation where available, then make the change once.
The point is not bureaucracy. It is preventing one mistaken keystroke from being “fixed” by a second unrecorded keystroke.
Do not assume that a proven clerking error automatically gives staff unlimited authority to increase an invoice, reverse a completed transaction or reopen bidding. Check the published Terms or Conditions of Sale, any sale-day announcements or amendments, platform rules that apply to the transaction and the auction house’s internal authorization path.
Where the correction is disputed, materially increases what the buyer owes, affects property that has already been released or changes a completed settlement, escalate before treating the corrected amount as final. Record the specific clause or section relied on in the correction record.
Some auction Terms give the auctioneer discretion to reopen or continue bidding after an error or dispute. Use that option only when the applicable Terms permit it, the auctioneer or other authorized decision-maker selects it, and the room plus any remote bidding channels can be returned to one verified bidding state.
Save the original hammer entry, bidder, amount, timestamps, bid source and any invoice or platform result already created. Mark that result as under review rather than silently overwriting it.
Identify the Terms or Conditions clause, sale announcement or other governing authority that permits reopening, continuing or reoffering the lot, and record who approved that decision.
Determine the last undisputed bid, bidder/source and next valid increment from the preserved sequence. Do not choose a restart amount merely because it is close to the suspected hammer.
Make sure the clerk, auctioneer, floor staff and any active online or phone bidding path know that the earlier result is being reopened and agree on the same lot and restart state before bids resume.
Use neutral wording that identifies the lot and restart point without blaming a bidder or clerk. Example only: “Clerking correction on lot X. The previous result is under review. Bidding is reopening from $Y.” Adapt the wording to the auction house’s Terms and normal auctioneer practice.
Record the reopened bidding sequence and final result through the supported workflow. Preserve the earlier result as superseded, cancelled or otherwise resolved according to the system and sale terms, then reconcile invoice, payment, settlement and release records from the final authorized result.
If property has already been released, payment or settlement is materially complete, the bidding channels cannot be synchronized, or the Terms do not clearly support reopening, keep the transaction on hold for management review instead of recreating a live auction sequence after the fact.
Do not skip from “that price looks wrong” to a changed invoice. Each step narrows the uncertainty and protects the audit trail.
Tell clerking, cashiering and pickup staff that the lot is under price review. Hold any step that would turn the questionable amount into a final invoice, payment, settlement or release.
Save the recorded lot number, bidder number, hammer amount, bid source, timestamps and visible event history. Note whether an invoice, payment or seller settlement already exists.
Verify the accepted bidder independently. If buyer identity is wrong or uncertain, route the incident to the bidder-number or disputed-result workflow before changing price.
Record the amount believed to have been accepted, who raised the discrepancy and whether the figure is a single-lot hammer, unit hammer, quantity-based amount or extended total. Keep it separate from the current system value until the evidence is reviewed.
Compare the clerking event sequence, online bid history, room audio/video, auctioneer notes, spotter notes and other contemporaneous records. Match lot, bidder, amount and sequence—not just one timestamp.
Before treating logs as contradictory, account for timezone, device clock offsets, platform delays and the difference between a bid being received and the auctioneer acknowledging it.
Identify the governing Terms or Conditions clause and the person authorized to decide the remedy. The approved path may be a clerical correction, a properly authorized reopening/reoffer while the sale can still be synchronized, or a hold/escalation when the result or authority remains uncertain.
For a clerical correction, use the platform’s supported correction, re-clerk or result-edit workflow and keep bidder identity unchanged unless a separate bidder error has been proven. If the authorized outcome is to reopen bidding, follow the Re-open Lot path and record the new bidding sequence rather than hand-editing toward a desired result. Add a correction note and preserve the earlier state where supported.
Recalculate buyer premium, tax and invoice totals; verify payment and receipt status; check seller settlement, commissions, exports, reports and lot release state. Do not assume all downstream records update automatically.
Tell affected staff and buyers which document is valid, preserve superseded records, record the evidence and authorization, and note the root cause so the next sale can be adjusted.
A clerk screen is useful, but it may be the source of the error. A room recording can capture the auctioneer’s call, but may not clearly identify a floor paddle. An online log can show a remote bid sequence, but not necessarily the exact moment of the auctioneer’s acknowledgement.
Use two or more independent sources where possible and document what each source actually proves.
Save the history before edits. Look for the previous bid, accepted bid, next event, source and any manual changes.
Use the auctioneer’s call, visible paddle, spotter acknowledgement and cadence to corroborate the amount and bidder.
Ask the auctioneer, clerk and spotter what they observed before discussing a shared reconstruction.
Use bidder portal history, absentee instructions or other buyer-facing records as corroboration, not as a substitute for the primary sale evidence.
A clerical correction is appropriate only when the sale result can be established. If the result itself is disputed, the operational job is to preserve evidence and escalate—not to pick the most convenient number.
| Condition | Status | Preferred operational action | Do not |
|---|---|---|---|
| Buyer proven; accepted amount independently established | Correctable price-entry error | Preserve original state, authorize one primary-record correction, then reconcile all dependent records. | Patch only the invoice. |
| Buyer proven; clerk value differs from room recording | Evidence conflict to resolve | Check full sequence, clock offsets and corroborating records before authorizing the corrected amount. | Assume the newest or loudest source is automatically correct. |
| Buyer proven; online log and floor recollection differ | Floor / online sequence issue | Hold the lot and reconstruct which bid the auctioneer acknowledged under the sale workflow. | Choose the value that produces the easier invoice. |
| Buyer uncertain as well as amount | Not a simple hammer-price correction | Preserve evidence and escalate bidder identity and sale status together. | Correct price while leaving an unproven buyer in place. |
| No reliable evidence establishes the accepted amount | Unresolved sale result | Keep downstream processing on hold and follow the auctioneer/management dispute process. | Reconstruct the amount from expected value, estimate or memory alone. |
| Error or dispute is caught while bidding can still be safely resumed and the sale terms permit reopening | Authorized sale-status remedy | Preserve the first result, verify the last undisputed bid and restart point, synchronize all active bidding channels, make a clear auctioneer announcement and re-clerk the reopened sequence. | Reopen from a guessed amount or silently erase the first result. |
| Error found after invoice was sent | Downstream document affected | Correct primary sale record, supersede the wrong invoice and issue one clearly identified replacement. | Leave two active invoice versions. |
| Error found after payment or settlement | Financial exception | Preserve payment/settlement history and correct under management/accounting controls with a complete audit trail. | Make an undocumented back-office balance change. |
| Property already released | Late financial / contract exception | Preserve the full transaction record, confirm the corrected balance and governing Terms, escalate immediately to management and communicate with the buyer in writing under the approved remedy. | Automatically charge, restrict, withhold unrelated property or start collection action without authority. |
Some auction systems propagate a corrected amount automatically; others require a separate invoice refresh, tax calculation, payment adjustment or settlement update. Do not assume either behavior.
After the primary sale result is corrected, work outward in one direction and verify the final values before the lot is released or the incident is closed.
Confirm the premium is based on the corrected hammer amount and that any threshold or rate behavior is still correct.
Verify tax after the price correction and after any invoice regeneration. Do not assume the old tax value will update automatically.
If money already moved, preserve the original charge or payment record and document any additional balance, refund or reversal through the normal payment process.
Confirm consignor proceeds, commission and sale totals reflect the corrected result before settlement is finalized.
Keep the message factual: what is on hold, what record was found to be inconsistent, what has been verified and which document is now valid.
Say that the hammer amount recorded for the lot is being checked or has been corrected. Identify the valid invoice version and any payment action needed.
Make sure staff cannot collect against an obsolete invoice or quote the old balance after the primary record has changed.
Do not release the lot from a printout or screen that predates the correction. Confirm the current invoice and release status first.
If the correction changes consignor proceeds or commission, identify the affected lot and keep the earlier settlement version in the audit trail.
Most prevention is procedural rather than technological. Make the accepted amount easy to hear, easy to confirm and hard to finalize without a quick plausibility check.
The goal is not to slow the auctioneer. It is to create small checkpoints around the moments where a fast verbal event becomes a permanent financial record.
Set a clear role for authorizing a price correction and a separate role for making or checking the edit.
Give the clerk a neutral repeat or confirmation procedure when the auctioneer’s amount cannot be heard clearly.
Document timezone and known clock offsets so bid logs, clerking events and room recordings can be reconciled after an incident.
Check unusually large jumps, manual edits, reopened lots, floor/online conflicts and lots specifically flagged by the auctioneer or clerk.
Use software permissions and audit logs that make it possible to see who changed a hammer price, when and from what prior value.
Before auction day, confirm how a corrected result flows into premium, tax, invoices, payment, seller settlement and release records.
The record should allow someone who was not in the room to understand what was wrong, what evidence established the accepted price and which records were replaced.

These answers focus on operational correction and record integrity. Sale terms, platform behavior and applicable rules remain controlling.
Hold downstream processing for the affected lot, preserve the original clerking state, confirm the buyer and gather evidence of the accepted amount before editing anything.
Only after the accepted amount is established and the correction is authorized. Capture the original state, use the supported correction path and verify all dependent records afterward.
Keep bidder identity unchanged. For quantity or Times-the-Money lots, first confirm whether the stored figure is a unit hammer or an extended total. Then correct the proven hammer amount in the primary sale record and reconcile premium, tax, invoice, payment, settlement and release status.
Do not treat it as a routine price-entry error. Hold the lot, preserve all evidence and escalate the sale-status decision to the auctioneer or manager.
Correct the primary sale record first, then void or supersede the incorrect invoice and issue one clear replacement. Verify the buyer-facing portal and any payment request before release.
Keep the payment history intact and stop further processing while the corrected balance is established. Handle any additional balance, refund or reversal under normal payment controls with a clear audit trail.
No. Preserve evidence of the earlier state and use correction notes, audit history, void or superseded documents where supported so the change can be reconstructed later.
Use clear call-confirmation habits, visible lot and bid state, synchronized clocks, edit history, exception review before final invoicing and a tested correction workflow.
Sometimes, but only when the applicable Terms or Conditions allow reopening or continuing bidding and an authorized auctioneer or manager chooses that remedy. Preserve the first result, establish the last undisputed bid and restart point, synchronize every active bidding channel, announce the correction clearly and re-clerk the reopened sequence.
Treat it as a late financial or contract exception rather than a routine clerk edit. Preserve the transaction record, confirm the corrected amount and governing Terms, escalate immediately to management, communicate with the buyer in writing and use accounting or legal review where the issue is material or disputed. Do not assume unrelated property, payment methods or bidder access can be restricted without authority.
Hold the affected lot, preserve the original entry, prove the accepted bid, make one authorized correction in the primary sale record and then reconcile every buyer, payment, seller and release record that depended on the wrong amount.
