Auction Software Development

The standard installation
does a lot. Sometimes you
need it to do more.

Payment gateways, custom bidding logic, full site redesigns, third-party integrations — built by the same team that wrote PHP Pro Bid. Every project is scoped and quoted individually.

Tell us what you need
Auction software development is the work of building or extending the software an auction business runs on: bidding engines, payments, catalogs, invoicing, and the workflows around them. PHP Pro Bid takes a platform-first approach — rather than a from-scratch build, custom features and complete custom auction platforms are developed on a proven auction platform that has run live sales since 2006. It is usually faster, cheaper, and easier to maintain.

We wrote the codebase

No reverse-engineering. No guesswork. We know exactly how every part of the software works — because we built it.

Nearly two decades of auction software experience

We've built for estate liquidators, charities, vehicle auctions, industrial clearances, and marketplaces. Chances are we've solved your problem before.

Built to stay maintained

Custom features we build integrate cleanly with the core software — so they survive version upgrades without breaking your platform.

What We Build

Custom work we take on

Whether you need a custom auction website built from the ground up, or a specific feature added on top of the 60+ standard features — if it runs on PHP Pro Bid, we can build it. Here are the most common types of project we work on. (Building a mobile experience? We also take on auction app development.)

Payment gateway integrations

Need a payment processor that isn't in the standard build? We integrate regional gateways, escrow services, split-payment systems, bank transfer workflows, and custom checkout flows directly into your platform.

Regional processors Split payments Escrow workflows Subscription billing Multi-currency checkout

Custom bidding logic

Bespoke auction rules beyond the standard feature set — reserve price behaviors, tiered buyer's premiums, lot bundling rules, live auctioneer override controls, custom increment tables, or any bidding mechanic specific to your industry.

Reserve handling Tiered premiums Live override Custom increments

Full site design & redesign

A complete custom auction website built on PHP Pro Bid — custom layouts, your brand identity, category-specific templates, and a visual experience tailored to your auction niche. From the homepage to the lot page to the checkout.

Brand identity Custom templates Category pages Mobile-first layouts

Third-party API integrations

Connect your auction platform to external services — inventory management systems, shipping providers, accounting software, CRM platforms, marketing tools, or any service with a public API. Data flows between your auction site and the rest of your business.

Inventory systems Shipping APIs Accounting software CRM integration Marketing tools

Custom user dashboards & portals

Tailored seller dashboards, bidder history views, consignor portals, admin reporting panels, and buyer account experiences. If your users need a specific view of their data, we build it to fit exactly how your business operates.

Seller portals Consignor views Admin reporting Buyer accounts

Advanced search & catalog features

Custom search filters, faceted navigation, saved searches, lot recommendation engines, category hierarchies, and dynamic catalog pages — built for the specific inventory types and buyer behaviors of your platform.

Why It Matters

A third-party developer builds on top of software they don't know. We built it.

When you hire a freelancer or agency to customize PHP Pro Bid, they start by learning how the platform works. That takes time, introduces risk, and means the work they produce may not survive the next version update.

When we build your custom feature, we know exactly where to add it, how it interacts with everything else, and how to keep it maintainable. The work is done by the same people who write every release of the software.

That's not a small difference. It's the difference between a patch and a proper implementation.

01

No learning curve on our end

We don't need to read the documentation before we start. We wrote it.

02

Clean integration with the core

Custom features are built to work with the platform's architecture — not bolted on in ways that break during upgrades.

03

One team, full accountability

If something goes wrong with a feature we built, you contact us — not a separate developer who's moved on to another client.

04

Nearly two decades of auction-specific experience

We've built auction platforms for estate liquidators, vehicle dealers, charities, and industrial firms — see the client showcase. We understand the domain, not just the code.

How It Works

From inquiry to delivered feature

Every custom project is scoped and quoted individually. Here's what happens from the moment you reach out.

1

You describe it

Tell us what you need the platform to do that it doesn't do today. The more specific, the better — but a rough idea is enough to start.

2

We ask the right questions

We review what you've described and come back with any clarifying questions. We identify the cleanest way to build what you need within the platform's architecture.

3

We quote it

You receive a fixed quote for the agreed scope. No hourly billing, no open-ended estimates. You know the cost before work begins.

4

We build & deliver

We build the feature, test it against your installation, and deliver it with documentation. You own the code.

Common Questions

Auction software development, answered

How much does custom auction software development cost?

A from-scratch custom auction platform from a development agency typically runs $15,000 to $100,000 or more. Building on PHP Pro Bid changes the economics: the platform base starts at £599, and custom work is a fixed quote on top — you pay for the features that are genuinely unique to your business, not for rebuilding bidding, invoicing, and buyer accounts from zero. See the pricing page for the platform plans; every custom quote is fixed before work begins.

Can you build a complete custom auction platform, not just single features?

Yes. Full custom auction platform builds are the largest projects we take on: your design, your workflows, your integrations, delivered on the PHP Pro Bid base and hosted wherever you choose. You get a platform that is genuinely yours, with the reliability of software that has run live auctions since 2006 — see the client showcase for platforms built this way.

Do you handle auction app development too?

Yes. Branded iOS and Android auction apps are a separate service, built on the platform's RESTful API and published under your own developer accounts. Details, modules, and process are on the auction app development page.

Do I own the custom code you build?

Yes. Custom features are delivered into your installation and belong to you, the same way the self-hosted license does. Custom feature code is delivered open; only a few of the platform's core licensing/security files are ionCube-encoded.

Can you customize an existing PHP Pro Bid installation?

Yes — most projects start from a live installation. We build against your version, test on a staging copy, and deliver features that integrate with the core so they survive version upgrades. If you are several versions behind, we will tell you honestly whether an upgrade first is the cheaper path.

Tell us what your custom auction website needs.

Every custom project starts with a conversation. Describe what you're trying to achieve — we'll scope it, quote it, and build it. No commitment required to inquire.
