Auction Software Development

Custom Auction
Software
Development

Work directly with the team that builds PHP Pro Bid. We customize existing installations and develop complete auction websites and standalone web apps from scratch. Every project is scoped and quoted individually.

Discuss Your Project
We customize PHP Pro Bid and build new software from scratch, including complete auction websites and standalone web apps. Your project can extend an existing installation or start with a new codebase. We review your requirements and scope and quote the work individually.

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

We customize existing PHP Pro Bid installations and build new auction websites and standalone web apps from scratch. Projects can range from one feature or integration to a complete application. Here are some of the types of work we take 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 for your auction website

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. Just need the design as a fixed-price package? See our Custom Premium Theme (£1,499).

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.

Faceted search Saved searches Lot recommendations Custom taxonomies

White-label and custom-branded auction websites

Every plan can use your domain, logo, colors, and theme. White-label auction software explains the Unbranding options. Choose custom development when the design, user flow, or platform behavior also needs to change.

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.

Who Does The Work

Auction website developers who wrote the platform

Some requirements can be handled through PHP Pro Bid’s existing settings, including custom fields and searchable listing attributes. Custom development is for changes beyond those settings, such as a new payment integration, a different bidding workflow, or a tailored dashboard. Describe your requirement so we can review the scope.

That covers custom features and integrations quoted per project, full custom auction websites built on the proven engine rather than a from-scratch build that spends your budget re-solving bidding, and branded auction app development for iOS and Android. How that decision works is set out in build, buy, or customize.

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 want to build or change and who will use it. A rough idea is enough to start.

2

We ask the right questions

We review your requirements, ask any clarifying questions, and identify an approach for the project.

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 and test the agreed features or application, then deliver the work.

Common Questions

Auction software development, answered

How much does custom auction software development cost?

Custom development is quoted individually after we review your requirements. You receive a fixed quote for the agreed scope before work begins.

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

Yes. We build complete auction platforms on PHP Pro Bid or from scratch, depending on your requirements. Projects can include custom design, bidding workflows, user accounts, payments, and integrations. We review the scope and quote each project individually.

Is there a fixed-price option for just a custom design?

Yes. If you need a bespoke look rather than backend feature work, our Custom Premium Theme is a fixed £1,499 package: custom layouts for four key pages (home, search results, listing details, event details), a custom listing card reused across every grid, your logo and color palette applied site-wide, the typography you choose, mobile-responsive throughout, and two rounds of revisions. Larger or multi-page redesigns beyond those four pages are still scoped and quoted per project.

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.

How do I choose an auction website developer?

Ask four things: have they shipped real auction platforms rather than general websites, do they build on a maintained platform or from scratch, will the people who know the codebase do the work, and will they commit to a fixed quote after scoping. PHP Pro Bid custom work is done in house by the team that writes the platform, scoped and fixed-quoted before work begins — see the pricing page for the platform plans.

Tell us what you want to build or change.

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.
