Measured against your previous Perth site at 60 days post-launch. We engineer for leads, tenders and revenue — the number on your P&L, not a portfolio screenshot.
Built and supported on Perth time, fast where WA crews work — often on a phone, on site, on a thin connection. Sub-2.5s mobile LCP is a non-negotiable, not an aspiration.
No WA account handed to a junior, and no waiting on the east to come online. The same senior pod scopes, builds and supports your system every week, on AWST — code your team can extend.
Senior engineering depth on Perth time is the rare and valuable part in WA.
Perth is the headquarters of Australia's resources sector — mining and minerals, oil and gas, and the deep METS ecosystem of mining equipment, technology and services — alongside construction, healthcare and professional services. The systems those firms need go well beyond a brochure site: asset and compliance dashboards, contractor and induction portals, quoting and tender tools, field-data capture that works on a phone with patchy signal at a remote site. That's real engineering — data models, secure back-ends, integrations — and senior development depth to build it is genuinely scarce in WA.
Most Perth brands face a hard choice. They hire a local freelancer who builds a template and goes quiet, or they outsource east to a Sydney or Melbourne studio that's still asleep when the WA business day begins, so a Friday-afternoon production issue waits until Monday lunchtime over there. As a web development agency Perth firms trust, we close that gap: a single senior pod that scopes the architecture, builds the system and supports it, running entirely on AWST. A deploy issue raised at 8am Perth time gets actioned at 8am, not after the east wakes up. We map your CRM, ERP and field systems in discovery and build two-way integrations so data flows automatically across the business, with clean, documented, tested code your team owns.
Performance matters more here than people expect, because WA buyers and field crews often work on a phone, on site, on a thin connection. So web development Perth has to be a performance discipline: the developers who build for us engineer speed in from the first commit — code-splitting, edge rendering, image and font optimisation, critical CSS — hitting 2.1s average mobile LCP and a 92+ Lighthouse score on launch, on 99.9% uptime infrastructure. A B2B website that has to survive procurement and tender scrutiny earns trust by being fast, credible and built to convert, all supported on your clock.
Every layer a Perth build needs, under one senior pod, on AWST.
Six web development capabilities, one team on Perth time: custom engineering, web apps, commerce, integrations and performance — design handled by our sister web design pod so the two never fall out of sync.

Web development in Perth, answered straight.
Still got questions? Our team replies to every enquiry inside 24 hours.
How much does web development cost in Perth?
Marketing and B2B-site development scales with integrations and complexity, while eCommerce and headless builds sit a tier above. Custom web applications and dashboards are scoped individually. We quote fixed-price after a discovery sprint, so there are no surprise invoices, and forecast the lead and revenue return before you commit.
How long does a Perth web development project take?
Most web development Perth projects run on a clear timeline: a custom marketing or B2B build 6–10 weeks from kick-off, an eCommerce or headless build 10–16 weeks depending on integrations, and a custom web application or dashboard 12–20 weeks. We work in two-week sprints with weekly demos on Perth time, so you watch the system come together rather than waiting on one big reveal.
What technologies and tech stack do your Perth web developers build with?
The web developers Perth businesses hire from us build with React, Next.js, Astro, Node and TypeScript for custom work; Shopify Plus and WooCommerce for commerce; and headless setups pairing a Next.js or Astro front-end with Sanity, Contentful or Storyblok. We pick the stack that fits your scale and your in-house team, not our preference, and ship clean, tested, documented code across all 47 builds we delivered in 2025.
Can you build a custom web application or dashboard, not just a website?
Yes — custom web application development is core to what we do in Perth. We build asset and compliance dashboards, contractor and induction portals, quoting tools and field-data systems for resources, METS and B2B firms. We scope the data model, design the architecture, build the app and wire up authentication, user roles and reporting, then ship it with documentation and tests your team can extend.
Can you integrate our site with our CRM, ERP and field systems?
Yes — API integration is part of most Perth builds. We connect sites and apps to CRMs (Salesforce, HubSpot), ERPs (NetSuite, Pronto), accounting (Xero) and field-service tools. We map your stack in discovery so quotes, jobs, orders and data sync automatically in real time across the business, with no manual re-keying between systems — and we run it all on AWST.
Do you build and support on Perth time (AWST)?
Yes — our Perth web development team works entirely on AWST, so we're live when your WA day starts rather than offline until the east wakes up. A deploy issue raised at 8am Perth time gets actioned at 8am, not after lunch over east. Senior engineering depth on your clock is the rare and valuable part in WA, and it's exactly what we offer with 99.9% uptime on every managed build.
How do you make Perth sites load in under 2.5 seconds?
Performance is engineered in from day one, not bolted on later. We use code-splitting, server and edge rendering, image and font optimisation, critical CSS and CDN caching, then measure Core Web Vitals before launch. The result averages 2.1s mobile LCP and a 92+ Lighthouse score — which matters in WA, where buyers and crews often work on a phone, on site, on a thin connection.
What makes a good web development agency in Perth?
In WA the bar is senior engineering depth available on Perth time: a good agency can model your data, build asset and compliance systems, integrate your CRM and ERP, and ship clean code your team owns — all supported on AWST, not from a team that's asleep. Look for a sub-2.5s performance standard and results benchmarked at 60 days. We've engineered Perth builds since 2013 and generated $650M+ for clients.
