Frequently asked questions

Are there any recurring fees or commissions?

No. The software is a one-time purchase hosted on your own server. You keep 100% of every hammer price — no monthly fees, no per-listing charges, and no commission on sales.

What are the system requirements for installing the auction software?

A standard modern stack: Apache or Nginx, PHP 7.4 or newer, and MySQL 5.7 or newer. Setup is included with every license, so we handle installation for you and provide full server recommendations.

Is there a limit to the number of auctions or users?

No built-in limits. The platform scales with your server capacity, and we can recommend hosting specifications based on the traffic and bidding volume you expect.

Can the auction software be customized to fit my brand?

Absolutely. Logos, colors, themes, and layouts are fully customizable, with documentation to guide you. The Custom and PRO licenses also include dedicated development hours for deeper changes to features and design.

Can I run real estate, car, or charity auctions with this software?

Yes. English, Dutch, sealed-bid, and silent auction formats are all supported, and the platform can be tailored to any industry — real estate, vehicles, industrial equipment, collectibles, or fundraising events.

How does the live auction feature work?

You stream the auction in real time while bidders place bids online as if they were in the room. It works with popular streaming services and needs only a stable internet connection.

Can I integrate third-party payment processors?

Yes. Popular payment gateways are supported out of the box, and documentation is provided for connecting additional processors of your choice.

Can I migrate data from another auction platform?

Yes. Our team assists with data migration to ensure a smooth transition from your current platform with data integrity preserved and minimal downtime.

How are security updates and support handled?

Every license includes 12 months of technical support, updates, and security patches, with clear instructions for applying them on your server. Support can be renewed annually at a reasonable rate afterwards.

Going once. Going twice.
