Built for auctions
The lots that pass are not worthless — they are unlisted.

From catalog to settlement, plus a second life for passed lots.

Auction houses juggle rapid lot cataloging, consignor and buyer accounting, and a pile of unsold lots after the hammer falls. ResaleOS speeds up cataloging, keeps settlements clean, and turns passed lots into online sales.

AI intake
Cataloging is the bottleneck.

Lots described and photographed in one pass.

Shoot the consignment on one table and each lot comes back with its own gallery, a written description, a category and a value backed by recent sold results.

Photos in, items out

Drop a batch of photos and they are grouped into separate products, each with its own gallery.

Written up for you

Title, description, brand, condition and category, filled in from what the photos actually show.

Priced off real comps

A suggested price backed by what the same piece recently sold for, not a number somebody guessed.

Built for a full intake

Work through a whole delivery in one pass instead of opening a product form for every piece.

Accounts
Settlement without the spreadsheet.

Every consignor’s terms, on the record.

Seller commission by value band, negotiated overrides, and the fees each consignment carries — worked out on the hammer price rather than at the end of the month.

Tiered by price

Build price bands — 50% under $500, 70% over $1,500 — and the right band is picked at the till.

Overrides where you need them

A different split for one account, one item, or one line at checkout. Everything else inherits.

Fees, split your way

Surcharges can come off the split base or each side after, worn by the store, the seller, or both.

Signed agreements on file

Your terms, signed on screen and versioned, attached to the account they belong to.

Invoicing
Invoice the buyer, settle the seller.

Invoices that collect themselves.

Turn a won lot into a branded invoice, email it with a pay button, and the sale is marked paid in your books the moment the card goes through.

Invoice #S-001234

Leather Jacket$189
Designer Handbag$220
Knoll Table$340
Pay $749.00
Branded and itemized

Your logo, your terms, every line the buyer is paying for, and the tax worked out.

Emailed in a click

It goes straight to the customer’s inbox with a pay button, not as an attachment they have to print.

Card payment built in

They pay online through your own Stripe account and the sale is marked paid without you touching it.

You can see it land

Sent, viewed and paid are on the invoice, so chasing is a glance rather than a guess.

Crosslisting
A passed lot is not a dead lot.

Give the unsold a second sale.

Anything that did not meet reserve goes straight to eBay, Etsy, Chairish and your own storefront, priced where it will actually move.
