Everything from the front door to the gavel

Stop stitching together email, spreadsheets, paper contracts, and sticky notes. Hammerworth runs the entire consignment lifecycle in one place.

Smart Intake

A mobile-friendly consignor form and a single triage queue. Category-specific fields, photo checklists, and tracked requests for what’s missing keep every inquiry moving.

Online submissionTriage queueTracked follow-up

AI Appraisal Studio

Draft appraisal research, object context, comparable records, and a value range in one workspace. Your qualified staff reviews every conclusion before placing the finished PDF in the client vault.

Collector CRM

Match incoming lots to collectors based on purchase history, then prepare focused campaign drafts for staff review and handoff to your existing marketing workflow.

Catalog & Handoff

Estimates, reserves, condition notes, and photography checklists flow into a clean, export-ready record — built to hand off to Bidsquare and the platforms you already sell on.

How it works

From “what’s it worth?” to settled

The same flow your team already follows, with one record from intake through settlement and a clear review point before client-facing work leaves the house.

1

Capture

Consignors and appraisal clients submit item details and provenance through one branded form, with photo follow-up handled by staff.

2

Evaluate

AI researches comparables and drafts values. Staff accept, decline, or generate a paid appraisal.

3

Market

Staff reviews collector matches and campaign drafts, then prepares catalog records for export.

4

Sell & settle

Records hand off as Bidsquare-ready CSV files; imported results update consignor history and settlement records.

Onboarding

Live before your next consignment call

Start a trial, make the workspace yours, import your history, and bring the team in. Complex data or integration needs begin with a scoped onboarding plan.

1

Start your trial

Two fields and a card — Stripe holds it, and day 15 is the first charge. Cancel before then and pay nothing.

2

Make it yours

Apply your logo, colors, and house identity across client-facing intake and portal views.

3

Import your history

Past sale CSVs become private comparables, a buyer list, and an unsold pool ready to re-offer.

4

Invite the team

The owner invites staff and appraisers; clients get a passwordless portal — nothing for them to manage.
