Run auctions on behalf of multiple sellers with confidence and control

What running a multi-seller auction actually involves

Running auctions for multiple sellers introduces additional operational responsibility. You are accountable for:

• Managing consignments from different sellers
• Presenting assets consistently under your brand
• Ensuring bidders experience a clear, trusted auction process
• Handling payments, fees, and settlement correctly
• Providing transparency and auditability for sellers and buyers

As scale increases, so does complexity.

Generic tools and third-party marketplaces often struggle here because they:

• Blur responsibility between operator and seller
• Limit control over rules, charges, and workflows
• Introduce risk around settlement and reporting
• Undermine trust when issues arise

For professional operators, control and clarity are non-negotiable.

How iRostrum supports the multi-seller model

iRostrum enables organisations to operate multi-seller auctions under their own brand, with clear separation of responsibility and strong operational oversight.

With iRostrum:

• You remain the auction operator, not a passive intermediary
• Sellers consign assets into your auction process
• Auctions run within your branded environment and domain
• Bidders experience a consistent, first-party journey
• Governance, reporting, and auditability are built into day-to-day operations

The platform has been shaped by over 13 years of supporting professional auction businesses, ensuring that multi-seller complexity is handled simply and predictably.

From both seller and bidder perspectives, the process feels structured, transparent, and trustworthy.

Designed for professional auction operations

Multi-seller auctions are where professionalism is tested most.

iRostrum is designed to support:

• Clear seller onboarding and consignment workflows
• Consistent catalogue presentation across sellers
• Predictable settlement and aftersales handling
• Oversight without micromanagement

This allows you to focus on running successful auctions — not firefighting operational issues.

How organisations typically evolve from here

Many organisations begin with a single-seller model and later introduce multi-seller auctions as their business grows. Others operate multi-seller auctions as their core model for years.

Some later choose to:

• Offer greater autonomy to sellers
• Introduce peer-to-peer listing models
• Run multiple operating models side by side

iRostrum is designed to support this evolution without replatforming.

If your operating model changes, the platform can adapt — allowing you to move into a marketplace model while retaining control over brand, bidders, and data. There is no forced transition, and no requirement to change how you operate unless you choose to.

What happens next

Every multi-seller operation has its own commercial and operational nuances.

A demo is the opportunity to:

• Discuss your seller model and consignment approach
• Confirm whether the multi-seller model is the right fit
• Explore how auctions integrate with your existing website
• Define clear next steps, including a tailored solution proposal

If you are running auctions on behalf of multiple sellers and need control, accountability, and flexibility, the Multi-Seller model is typically the right choice.
