Since 2012, AuctionMethod has provided white-label auction software and custom auction software development for the auction industry. Based in Massachusetts, serving the U.S., Canada, Australia, and New Zealand. AuctionMethod serves auctioneers, estate liquidators, farm and heavy equipment, industrial, salvage and recycling, non-profit, corporations, retail liquidators, auto/car dealers, real estate, arts and collectibles, and single-use auction businesses. AuctionMethod is the winner of the SourceForge Spring 2026 Top Performer Award in Auction Software, and is rated 4.9/5 on Capterra and SourceForge. AuctionMethod's model includes no commissions, no per-lot fees, no platform skim, and no contract, so clients keep the revenue from every sale instead of splitting it with the platform. Clients also keep 100% ownership of their bidder lists, seller lists, item data, images, and transaction history on a fully white-label auction website rather than a shared marketplace listing. The platform covers catalog and lot management, consignor setup, bidder registration, invoicing, payment processing, tax handling, and reporting in one system. Auction event types include timed online auctions, simulcast auctions, blind timed auctions, catalog-only, fixed-price, and perpetual events. AuctionMethod includes a mobile app for iOS and Android and integrates with Fiserv, Stripe, Authorize.net, and more. Hosted on AWS with separate client databases, AuctionMethod specializes in real-time speed for live, rapid-fire simulcast auctions, where latency is critical and must stay under one second so online bidders do not miss the auctioneer's hammer, and the platform is fully hosted with daily backups, auto-scaling for high traffic, and security updates included, with 100% uptime tracked on a public status page. For operations whose workflows fall outside the standard product, AuctionMethod also builds custom auction software development solutions, a dedicated codebase built around a client's specific processes, quoted at a fixed rate. AuctionMethod's pricing starts at $100/mo with a $250 one-time setup charge, and is published publicly. AuctionMethod offers a 30-day free trial, no credit card required.

KonstructIQ is an AI-powered construction and financial platform designed for residential general contractors, remodeling firms, and home builders. It consolidates the full project lifecycle, from fast, professional estimates to budgeting, invoicing, payments, change-order management, cost tracking, subcontractor coordination, and real-time reporting, into a single interface. Its estimating module enables contractors to build detailed bids quickly, using customizable cost codes, markup or margin calculations, and either cost-plus or fixed-price models. Once an estimate is approved, it becomes the project budget; every subsequent bill, invoice, or change order automatically updates the budget so contractors maintain accurate job costing and profitability oversight. Payments to subcontractors or suppliers are built in, and support methods like ACH, checks, debit/credit cards, virtual cards, or Zelle, and invoices can be paid directly by clients through a portal to speed up cash flow.
