Online car auction software with proxy bids and a reserve.
Yclas is online car auction software for timed vehicle auctions: each car is a listing with a starting price, an optional reserve and buy-now price, and an end time. Bidders set a maximum, the site bids for them, late bids extend the clock, and the winner gets an order to pay.
Free for 15 days · No credit card · Auctions from the Professional plan, $99 a month


Online car auction software for sellers who want a market price.
A timed auction suits cars whose price is uncertain: classics, project cars, ex-fleet units and trade-ins.
A car auction, from lot to winner.

Proxy bids, a reserve, and buy now.
A bidder enters the most they will pay. The site shows only the smallest price needed to lead and bids for them automatically up to their maximum, as eBay does. A seller's reserve stays hidden: bidders see "Reserve met" or "Reserve not met yet". A buy-now price, if set, ends the auction at once for the first bidder who accepts it.
- Bid steps: a ladder that grows with the price (steps of 100 from 5,000, of 250 from 10,000), or one flat step you set.
- Ties go to the earlier bid.
- Outbid emails as soon as someone passes a bidder's maximum.

No sniping in the final seconds.
A bid in the last five minutes pushes the end time five minutes past that bid, so others can answer. You set both numbers, or switch it off. When the time is up the auction closes by itself: sold, reserve not met, or no bids.
- Who may bid: any signed-in user, or verified users only.
- Sellers cannot bid on their own car, and can cancel only before the first bid.
- Emails to outbid bidders at once, and to the winner and the seller when it ends.

The winner gets an order to pay.
When a car sells, Yclas creates an order for the winning bid, plus the seller's shipping price if they set one, and emails the winner a link to pay at your site's checkout with the payment providers you use. If the reserve was not met, no bids came in, or the winner has not paid within 14 days, the seller can relist the car or sell it at a fixed price.
- Not included: transport, title transfer, inspections or a buyer's premium.

Timed online auctions, not a live auction house.
Yclas runs timed auctions on listings. It does not replace a live auction with an auctioneer.

What is online car auction software?
Software that runs timed vehicle auctions on a website: each car takes bids until its end time, with rules for bid steps, reserves and late bids, then the winner pays the seller. Yclas does this on listings, next to normal fixed-price cars.
Does the online car auction software support a reserve price?
Yes. The seller sets an optional reserve; bidders only see whether it has been met. If the top bid stays under it, the car does not sell automatically and the seller can relist it.
Is there a buy-now price?
Yes, optional. It must be above the starting price and the reserve, and the first bid at that amount ends the auction.
How do you stop last-second sniping?
A bid within the last few minutes extends the end time. The defaults are a five-minute window and a five-minute extension; you can change both or switch it off.
How does the winner pay?
The site creates an order for the winning bid plus any shipping price and emails the winner a link to pay at checkout. If they do not pay in 14 days, the seller can relist.
Can I limit bidding to verified buyers?
Yes. In Settings › Auctions choose verified users only.
Do you offer live or simulcast auctions?
No. Auctions are timed and online only. Transport, title transfer and inspections are not part of Yclas either.
Which plan do I need?
Professional ($99 a month) or Marketplace ($149), with the Nova theme.
