🔨 For Auction Houses & Valuers

The Bidding Platform Is Solved. Your Back Office Isn't.

Valuation-day intake, consignor records, lot cataloguing with photos, vendor statements, and probate & insurance valuation reports — the spreadsheet-and-notebook middle of a regional auction house, built into one fixed-price system you own. Founded by a former multi-location jeweller, so the highest-value lots crossing your table are familiar territory.

Fixed price from €3,000 · €490 prototype sprint to start · You own the code · 7 apps approved on the Shopify App Store

Valuation Day Runs on Paper and Goodwill

"

Intake is a queue, a notebook, and a camera roll

Vendor details in one place, item photos in another, estimates on a slip of paper. Matching them up afterwards eats the week.

"

Consignor history lives in someone's head

Who consigned what, what it made, who's owed a statement — when that person is on holiday, the house is guessing.

"

Probate valuations are formatted by hand, every time

Solicitors and insurers want consistent, professional reports. Rebuilding the same document in Word for every estate is not a workflow.

"

The catalogue is retyped from the intake notes

Item details entered at valuation day should flow to the lot catalogue — not be transcribed a second time with fresh errors.

Assembled From Patterns We Already Ship

We don't sell an off-the-shelf auction product — we build your back office, fixed-price, on production patterns from our jewellery suite.

Valuation-day intake

Item, photos, estimate, and vendor captured in one pass — the intake pattern our Jewel Value app ships for jewellery appraisals.

Probate & insurance reports

Consistent, professional valuation documents generated from the record — not rebuilt in Word per estate. Jewel Value's certificate engine, re-templated for your house.

Consignor CRM

Every vendor's items, sales, and statements in one history — the client-record pattern from our JewelryStudioManager CRM.

Lot flow

Intake → catalogued → offered → sold or returned, with photos and provenance attached — the item-lifecycle engine behind our RepairDesk app.

Vendor notifications

"Your items are catalogued", "your statement is ready" — automatic email/SMS with consent handled properly.

You own everything

Code, data, hosting logins. No per-lot fees, no commission clip, no platform lock-in. EU-hosted by default.
