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.
