Auction software 2.0 · Proven on a working saleroom
They keep your customers. We hand them back.
Software that adapts to you, not the other way round.
UBERHAMMER, the Uber of auction software, is the bidding platform, back office and website behind a working UK auction house, built around your saleroom, changed whenever you ask, and priced at 3% of the hammer. Nothing else.
One shared platform. A template website. A surcharge on your bidders.
Built around your saleroom. Your own domain. 3% of the hammer, nothing else.

Pricing
of the hammer price, plus VAT. That is the entire price list.
You pay after the sale, on what sold. If a lot doesn't sell, you pay nothing for it. If you want the software changed, you pay nothing for that either. There is no other line on the invoice.
If the hammer doesn't fall, there is nothing to invoice. You pay 3% on the lots that sell, and not a penny on the ones that don't.
Worked out
Three examples. The arithmetic is the same at every size, and it is the only arithmetic there is.
| Hammer price | You pay |
|---|---|
| £120 · a box of tools | £3.60 |
| £1,000 · a Georgian bureau | £30.00 |
| £25,000 · a good painting | £750.00 |
| Unsold · any lot | £0.00 |
One line on the invoiceFigures are an illustration, not any saleroom's statement. Replace £60,000 with your own hammer total and the rest follows.

Built on a working auction house
We didn't build this in a lab. We built it on the floor of Badgers Auctions in High Wycombe, one weekend sale at a time. It's still there, taking over 1,200 lots a week.

The difference
Your bidders stay yours. The software bends to you.
A marketplace keeps your bidders on its books and gives you software to fit around. We do the opposite. Your bidders stay yours, and we build the software around you and them.
"Here's the platform. Fit around it."
- Your bidders register with the marketplace, not with you.
- It holds the list, the history and the marketing consent.
- It can email your bidders about everyone else's sales.
- Your buyers pay a surcharge to bid online.
- One platform, the same for every auction house on it.
"Tell us what you need. We'll build it, for you and for your customers."
- Your bidders register with you, on your domain.
- You hold the list, the history and the consent. Export it whenever you like.
- Only you ever email them, and only about your sales.
- No surcharge on your buyers.
- Software built around your saleroom, and changed when you ask.
Your domain, your brand, your terms
Bidders never leave your site to register, bid or pay. The address bar says your name from the catalogue to the invoice.
Export everything, whenever you like
Bidders, vendors, lots, results, invoices and statements, as CSV, on demand. No request form, no notice period, no fee.
We never market to your bidders
No alerts pointing them at other salerooms, no shared marketing list, no 'you may also like'. The only emails they get are yours.
- BiddersEveryone registered with you
- Vendors and statementsAll time
- Lots and resultsFull archive
- Invoices and paymentsAll time
Made to your instruction
Tell us how your saleroom works. We'll change the software, not you.
Every auction house runs differently: your increments, your soft close, your storage charges, your vendor statements, your collection days. On UBERHAMMER those aren't settings you work around. They're things we build for you, under your instruction, at no charge.

Product
Everything a saleroom runs on, in one place
Catalogue, bidding, payments, vendors and your website, sharing one database so nothing is typed twice. What's running today is marked. What isn't, we build for you.
Cataloguing and lotting
Bulk upload, assisted descriptions, a hundred categories, star lots and estimates. Sixteen hundred lots a week without a bottleneck.
Timed bidding
Real-time over a persistent connection, so bids appear without a refresh. Maximum bids, soft close, watchlists and email notifications.
Built to orderLive rostrum bidding
Video and audio from the rostrum with a clerk's console, built around how your auctioneer actually calls a sale. Tell us your format and we build it.
Bidder accounts
Email-verified registration, your registration rules, watchlists, maximum bids and a block list that is yours alone.
Invoicing and payments
Invoices raised as lots close. Card, Apple Pay and Google Pay online; cash and card on collection. Storage charges built in.
Vendors and reconciliation
Vendor statements, commission and lotting fees, weekly client-money reconciliation, and payouts on your schedule.
Archive and price guide
Every past lot with its hammer price and bid count, searchable by the public. Free marketing that compounds every week.
Your website
Designed for your saleroom and served on your domain, with the catalogue, bidding and checkout built in rather than framed in.
Collection and delivery
Collection windows, nominated couriers, and a report-an-error link on every lot so mistakes are caught before they cost you.
Switching
Weeks, not a quarter.
We moved a working saleroom onto the rebuilt platform between weekly sales. This is the order it happens in, and there is nothing to pay until your first hammer falls on the new system.
- 01
A conversation about how your sales run
Formats, increments, premiums, vendor terms, collection rules, the things your staff do on a Monday. We write it down and build to it.
- 02
We import what you have
Bidders, vendors, catalogue and archive from your current system. Your bidders keep their history; nobody re-registers.
- 03
Your site goes up on your domain
Designed around your saleroom, with the catalogue, bidding and checkout built in. You approve it before anyone else sees it.
- 04
Run a sale alongside your current platform
Your team runs a real sale on UBERHAMMER while the old system is still there. Anything that isn't right, we change that week.
- 05
Go live, and keep asking
From here on, every change you want is a message to us. The invoice is 3% of what sold, and nothing else.
Fair questions
The things auctioneers ask us first
Straight answers, including the ones that don't flatter us.
- A marketplace brings me bidders I'd never reach on my own. Doesn't leaving lose them?
- Keep listing on a marketplace if it brings you buyers. UBERHAMMER runs your own site alongside it, and every bidder who registers with you directly is yours from then on. Our first saleroom lists over 1,200 lots a week without one, but that is its choice, not a condition of using the software.
- We run live sales from a rostrum, not timed sales.
- Timed sales are what's running today. Live rostrum bidding, with video, audio and a clerk's console, is built to order around the way your auctioneer calls a sale, and you run it alongside your current platform until you're satisfied with it.
- Is 3% actually cheaper than what I pay now?
- Only you can answer that, because the marketplaces don't publish what they charge auction houses. Ask for a written breakdown of everything you paid last year, including set-up, subscriptions, per-lot charges and training, and put it next to 3% of last year's hammer total. Then add what your bidders paid in surcharges and flat fees, because that money shapes what they bid.
- How do thousands of bidders move across?
- We import your bidder list with its history, so nobody starts from nothing. Whether you may email those bidders about the new site depends on the consent you already hold, and we'll work through that with you before launch rather than after.
- Who are 1983 Ltd, and what happens if you disappear?
- A small software company that has built and run a working auction platform since 2022. You deal directly with the people who write the code. Your site runs on your own domain and your data exports at any time, so nothing about the arrangement can hold you.
