iRostrum

Property Auction Software for Real Estate Sales

Run professional property auctions on your own fully branded platform — designed to support residential, land, and commercial property sales, while delivering a trusted, compliant buyer experience.

iRostrum is a purpose-built property auction and bidding platform that enables you to run traditional live auctions and timed online auctions — including sales via the Modern Method of Auction — on your own website. Unlike generic portals or bolt-on bidding tools, iRostrum gives you complete control over your auctions, your buyers, and your data.

Since 2020, we’ve supported property professionals across the UK, US, and Europe — powering everything from single-lot disposals to large-scale, multi-agent auction operations.

Built for auction-led property sales

iRostrum is designed specifically for property auctions, not listings with bids added on. Whether you’re launching a new auction model, modernising an existing operation, or scaling across agents and regions, our platform gives you the flexibility to run property auctions your way.

With iRostrum, you can:

  • Run live, timed, or hybrid auctions from a single platform
  • Support Traditional (Unconditional) auctions and the Modern Method of Auction (MMoA)
  • Launch quickly with a proven SaaS platform — without the cost or risk of building from scratch
  • Operate under your own brand, with full ownership of buyer and bidder data
  • Scale from pilot sales to hundreds or thousands of listings without increasing operational overhead

Supporting both Traditional and Modern Property Auctions

Traditional (Live) Auctions

Also known as Unconditional Auctions

Traditional auctions are designed for speed and certainty.

  • Contracts are exchanged immediately when the auction concludes
  • Buyers pay a % deposit and any applicable reservation fees
  • Completion typically takes place within 28 days
  • Best suited to cash buyers, investors, commercial property, and development sites

iRostrum supports live-streamed and in-room auctions, with tightly controlled bidding, deposits, and post-auction workflows.

The Modern Method of Auction (MMoA)

Also known as Conditional Auctions

The Modern Method of Auction offers greater flexibility and access to a wider buyer audience.

  • Buyers secure the property by paying a Reservation Fee
  • Contracts are exchanged and completed within 56 days of receipt of the draft contract
  • Additional time allows buyers to arrange finance, making the process suitable for mortgage-backed purchasers
  • Ideal for residential sales and continuous listing models

iRostrum supports rolling listings, timed online-only auctions, legal pack handling, and buyer verification — all configured to align with MMoA requirements.

 

One platform. Multiple auction models.

Whether you run:

iRostrum adapts to your operating model — not the other way around.

Real Estate & Property Specific Features

Designed to present property at its full value

Property auctions demand more than basic listings. iRostrum provides the tools to present assets professionally and build buyer confidence.

High-quality property presentation includes:

  • High-resolution image rendering with close zoom control
  • Unlimited images per lot
  • Video and interactive 360° image support
  • Customisable property templates with icons, tables, and structured data
  • Search and filtering by location, property attributes, and closing time

 

Whether buyers arrive via portals, campaigns, or direct traffic, they experience a clean, professional, property-first journey.

Built-in trust, transparency, and due diligence

Trust is critical in property transactions. iRostrum embeds transparency and auditability throughout the buyer journey.

Key due diligence features:

  • Upload and manage multiple legal and information packs per lot
  • Controlled access to documents for registered users only
  • Time-stamped tracking of every bidder document download
  • Clear audit trails supporting compliance, solicitor workflows, and dispute resolution

Secure payments and bidder commitment

iRostrum provides flexible payment and deposit controls designed for property auctions.

Payment and commitment options include:

  • Credit card capture during registration or auction sign-up
  • Mandatory bid deposits or reservation fees
  • Subscription-based bidder access (where required)

You decide how and when buyers commit financially — based on your auction model.

Compliance without friction

Property auctions require robust compliance, without slowing down sales.

iRostrum supports:

Compliance is embedded into the auction flow, not bolted on afterwards.

Built for multi-agent and scalable property operations
