Sequence & duplicates
We scan every lot number for gaps, skips, and duplicates before your catalog goes live, so the running order actually runs.
A second set of eyes on every catalog.
Send your lot data 48 hours before the sale. Get back a one-page check and a recovery packet by 7 AM — missing lots, duplicates, missing photos, reserve oddities, and anything that quietly changed since your last file.
September Estate Sale
Lot 118 — duplicate lot numberCritical
Lot 204 — missing photoWarning
Lot 89 — reserve changed since last fileWarning
The mistakes that reach bidders are the ones nobody double-checked.
GavelCheck reads your export the way a second staffer would, if you had one free the night before every sale.
Photos & fields
Every lot is checked for a photo and complete required fields — condition, estimate, reserve — before a bidder ever sees it.
Diff against your last file
We compare your new export against the last one we saw and flag anything that quietly changed — price, description, lot order.
How it works
One file in, one report back, before you open the house.
Export your lot data
Any CSV from your existing auction software works — no new format to learn.
We check it overnight
Your evening is our workday in Japan, so the check runs while your team is off the clock.
Sale-day-ready by 7 AM
You get a one-page check and a recovery packet, in time to fix anything before doors open.
Your auction software stays the system of record. GavelCheck never touches sale day — no bidding, no clerking, no payments. It's a second check and a backup.
