01
Lot catalog & media
Categories, descriptions, images, reserves, increments, and scheduling for timed or live events.
Auction Software
Custom auction platforms for live, timed, and online sales.
Brown Kapitaal builds Laravel auction software for houses and marketplaces that need trustworthy bidding, clear clerk control, and settlements that match how you actually run sales—not rigid off-the-shelf products.
What We Build
From catalog to hammer fall to settlement.
We have delivered auction software where bid integrity, operator workflows, and financial handoff matter as much as the bidder experience.
02
Bidding engine
Proxy bids, max bids, increment rules, anti-sniping extensions, and authoritative server-side validation.
03
Live & simulcast sales
Clerk screens, floor and online bid combination, lot switching, and real-time bidder updates.
04
Buyer registration
Accounts, approval, deposits or credit limits, paddle numbers, and watchlists.
05
Consignor & seller tools
Intake, commissions, statements, and visibility into lot performance before and after sale.
06
Invoicing & settlement
Buyer premiums, taxes, payment capture, consignor payouts, and exportable financial reporting.
Auction Types
Platforms shaped around how you sell.
Industrial & equipment
Heavy machinery, fleet disposals, and inspection-heavy lots with location and pickup workflows.
Estate & collectibles
Multi-lot catalogs, condition notes, and buyer trust patterns for high-value discretionary purchases.
Charity & benefit auctions
Donated items, mobile bidding, and simplified settlement when the goal is fundraising velocity.
B2B marketplaces
Recurring timed sales, seller onboarding, and fee models when you operate a platform—not only your own inventory.
Why Teams Hire Us
Auction logic that stays correct under load.
Server-authoritative bids
Every bid is validated on the server so concurrent bidders and proxy rules do not corrupt results.
Operator-first tools
Clerks and admins get workflows for lot control, bid approval, exceptions, and post-sale adjustments.
Payment-ready settlement
Integrate gateways and accounting exports so finance can close the sale without re-keying totals.
Phased launches
Start with timed online sales, add live simulcast, then expand consignor and marketplace features.
Experience
Built for auction operators, not generic e-commerce.
Brown Kapitaal has implemented auction software where bidding rules, clerk oversight, and settlement workflows are central. That experience carries into new builds—whether you are replacing legacy software, launching a niche marketplace, or adding online timed sales to an established house.
FAQ
Common questions from auction teams.
Do you build live, timed, and hybrid online auctions?
Yes. We implement catalog and lot management, registration, bidding rules, clerk tools, and checkout flows for timed auctions, simulcast-style live sales, and hybrid events where online and floor bids combine.
How do you handle real-time bidding and high concurrency?
Laravel backs authoritative bid logic, validation, and settlement while real-time channels notify bidders of outbid status, lot changes, and clock extensions. We design for race conditions, proxy bids, and anti-sniping rules your auctioneer defines.
Can you integrate payments, invoicing, and buyer premiums?
Yes. We connect payment gateways, generate buyer invoices with premiums and taxes as configured, and support settlement workflows for consignors—scoped to how your auction house or marketplace operates.
What auction types do you support?
Common builds include industrial and equipment auctions, estate and collectibles, charity sales, and B2B marketplaces. The platform is shaped around your lot model, fee structure, and whether sellers are consignors or direct listers.
How long does an auction platform MVP take?
A focused MVP—catalog, registration, timed bidding on a subset of lots, clerk approval, and basic invoicing—often ships in 10–16 weeks when rules and payment scope are clear. Full live-auction and multi-tenant rollouts are phased.
Why Laravel for auction software?
Auctions need reliable transactions, role-based access, queues for notifications and settlements, and deep integration with payments and shipping. Laravel is a strong fit for custom auction platforms where off-the-shelf products do not match your process.
