Frequently Asked Questions
Why are estate liquidators and auctioneers switching to AuctionNinja?

We'd need way more space to cover all the reasons (wink;) but our customers tell us it's because of our unparalleled value, top-notch customer service, extensive, vetted bidder-base and because we're the most customizable and easy-to-use solution on the market.

What differentiates you from your competitors?

We covered a lot of them, but some other key differences are our automated invoicing and bidder notifications, as well as our auto-payment collection at auction close. We also offer UNLIMITED product listings & a FREE listing in our company directory.

I'm new to online auctions and need some help getting started. Will I have support?

Of course. We pride ourselves on our customer service and we'll be there to make sure that you get your auctions up and running as quickly and smoothly as possible

I'd like to host online auctions, but I have in-person sales too. Can I use AuctionNInja for both?

Yep. And the best part is, traditional, in-person estate sale listings are free when you register as an AuctionNinja seller.

Is the AuctionNinja platform only for estate sale companies and auctioneers?

While our software has been developed with the auctioneer and estate sale professional in mind, it is widely used by other types of sellers including coin and collectibles dealers, sports card vendors, non-profits and more.

What else should I know before choosing estate auction software?

Bottom line, if you're looking for the best, most cost-effective and comprehensive auction and estate liquidation software on the market, look no further. Don't take it from us - read what our customers have to say!

We know you want flexibility in your business. Our easy monthly subscription-based options plus a low per auction commission keeps your expenses in check and gives you complete flexibility.
