The Challenge

The company is a high-volume online auction operator for municipal and institutional surplus. It runs auctions for vehicles, heavy equipment, business liquidations, real estate and tax-foreclosure property, on behalf of hundreds of government and institutional consignors. Operating on that scale carries a specific set of demands that off-the-shelf auction software is not built to handle:

    • Every auction has to close cleanly and on time for buyers who are often watching countdowns on desktop and mobile simultaneously. 

    • Every invoice has to apply the right sales tax across multiple states and account for state-specific rules like caps and county surtax on combined lots.

    • Consignors at government agencies expect combined, audit-ready reports on demand, in formats that plug into their own accounting systems. 

    • Bidder identity and bid integrity have to hold up under scrutiny, because a single misfired proxy bid or a phantom high bidder becomes a complaint that lands on a municipality’s desk.

       

The way the company conducts business has been reshaped by government procurement changes that have affected the entire vertical. Winning and keeping state and county contracts increasingly depends on the company's response to detailed RFPs, its documented security posture, and now accessibility. 

The Department of Justice's 2024 ADA Title II web rule requires state and local governments to bring web content to WCAG 2.1 Level AA. The rule technically applies to the government agency, not the vendor. However, when the agency's auction platform is where the public interacts with a public entity, the platform has to conform, and the consignor has to be able to prove it.

Over just a few weeks, nine of the company's government clients requested a VPAT and full conformance results.
A generic platform or a marketplace would have forced their team to produce all of that in a rush, without support.

The Approach

The company runs a custom-developed AuctionMethod platform on its own branded domain. The platform has been built around this vertical’s workflows:

    • Soft-close countdown timers keep bidders from losing lots to page refreshes. 

    • Proxy and max bids fire correctly every time.

    • Consignor management carries role-based permissions for salespeople and administrators, and reporting and CSV export can be handed to a government consignor without reformatting. 

    • Multi-state sales tax is calculated automatically, with Avalara integrated for advanced tax lookup. 

    • A VIN-lookup and AI-assisted lot generation workflow lets the team spin up vehicle listings faster, and a dedicated real estate flow supports online tax sales. 

    • Bidder whitelisting, IP controls, and admin alerts on account changes handle the fraud and identity issues that come with public-facing government auctions.

The AuctionMethod team acts as the company’s outsourced platform, engineering, and DevOps partner, owning hosting, SSL, payment gateway, email deliverability, staging environments, and a dedicated development backlog. A standing weekly check-in meeting keeps priorities aligned, with in-person working sessions layered in. 

The custom-developed model is what makes the harder work possible. When the ADA Title II rule set a deadline for the company's largest consignors, the company paused its product development roadmap, replaced a partial third-party overlay with a full accessibility remediation program run against third-party audits, and drove toward WCAG 2.1 AA conformance documented in a VPAT.

AuctionMethod's co-founder personally led the initiative. When state and county RFPs came in, AuctionMethod supplied the company with hosting, security, and compliance answers directly, and co-presented live demonstrations to government procurement bureaus.

“When nine of our government clients asked for a VPAT in the same stretch of weeks, we didn't have to scramble for answers. AuctionMethod came to the table with a path forward. The feedback from our discussions has been overwhelmingly positive, and there’s a lot of excitement among our team, knowing that we are ahead of the requirement's deadline instead of chasing it.”

The Results

1

More than $70M in Sales Across 4,500+ Auctions 

In a single 12-month window, the company moved 30,000+ lots and 16,000+ invoices through 4,500+ auctions, resulting in over $70M in revenue and averaging around $15K in sales per auction. Credit card volume accounted for nearly a quarter of total sales. That’s the throughput of an operation whose auction close, invoicing, and payment steps clear without manual intervention.

2

A Record Month Approaching $8M

The company's highest month on record in this window ran 460+ auctions and handled 2,900+ unique bidders. That month also produced the largest single auction in the period at 500+ lots and the highest monthly invoice count. The trajectory across the year was steady. More than half of the months cleared $6M or more in sales, and the platform handled peak-month volume roughly a third higher than the trailing average without a corresponding jump in staff.

3

~36% Repeat-Bidder Rate

At their high point across the full year, monthly repeat-bidder rates climbed above 40%, meaning more than one in three bidders came back to bid again. Bidders don't return if a sync error costs them a lot or a bill comes out wrong. A repeat rate this high isn't a coincidence. It's proof that auction close, bid integrity, invoicing, and payment were all working end to end.

State, County, and Municipal Procurement Support

Over the last two years, AuctionMethod supported the company through a state-government bid, a live virtual demonstration to a state Department of General Services procurement bureau, and RFP responses for county and municipal contracts across multiple states. On the accessibility front, the company moved from a partial third-party overlay to a full remediation program targeting WCAG 2.1 AA conformance, documented in a VPAT. The DOJ has since extended the Title II compliance date to April 26, 2027 for public entities serving 50,000 or more, which gives this operator runway to finish remediation well ahead of its consignors' deadline. In sales conversations against its primary competitor in the government-surplus space, that compliance readiness is now a lead differentiator.

Internal Reference Standard 

Product work built for this customer, including a smart search implementation on the homepage, set the internal reference standard. Other Custom Solutions clients now ask AuctionMethod to build them a similar system.

The Takeaway

For an auction business in the government and institutional surplus space, the choice of a platform comes down to whether it can keep up as procurement rules, compliance deadlines, and consignor expectations shift. The answer for this operator was a custom-developed platform paired with a hands-on development partnership.

That combination is what let them clear more than $70M in a single year, keep more than a third of their bidders coming back, and pause a live roadmap to run a full accessibility remediation the moment a federal deadline landed on their consignors.

"When we ask for something new, we get a timeline the same week, and it holds. Our weekly working session isn't a status update. It's where roadmap decisions get made and dates get committed. Nine years in, that cadence is why this still feels like a partnership and not a vendor relationship."
