The leading SaaS product development team for Australian founders

We're a Sydney-based B2B SaaS development agency. We help Australian founders ship the right v1 instead of the bloated one.

Senior engineers from week one. Fixed pricing per phase. Weekly demos. We push back on bad scope before it eats six months of your runway.

Custom SaaS development from design to build

Custom SaaS means software built around your product, your customers, and your commercial model. We build the frontend, backend, billing, integrations, and AI features from scratch.

Sydney startups launching v1. Melbourne scaleups rebuilding a platform that has outgrown its first architecture. Brisbane operators turning an internal tool into a subscription product. We've done all three.

Custom SaaS web app for Search Property, built by Webhouse in Sydney, Australia

Ideal for all types of B2B and AI SaaS builds

We work across most B2B SaaS categories. The throughline is custom: products that don't fit a Shopify or HubSpot template and need real engineering behind them.

B2B SaaS MVPs

First-release products for new founders raising or pre-revenue. Tight scope, fast to launch, built to learn from real users.

Multi-tenant platforms

Workspaces, accounts, roles, and permissions done properly so the product can serve thousands of customers without rewrites.

Vertical SaaS

Software built for a specific industry: trade, field service, healthcare, legal, professional services, real estate, and more.

Internal tools that became products

Operations and admin software you already use internally, productised and packaged for external customers to subscribe to.

AI-native SaaS

Products where AI is the core differentiator, not a bolt-on. Agents, copilots, structured outputs, and human-in-the-loop workflows.

Replatforms and rebuilds

Existing SaaS products that have outgrown their first architecture, drowned in tech debt, or need a sharper second swing at v1.

Custom web apps

Bespoke web applications that are not subscription products yet, but need real engineering behind them: portals, dashboards, marketplaces.

Recent case studies

Our complete SaaS development process

How Webhouse builds SaaS in Sydney: four phases from first conversation to a SaaS product compounding with real users. AI-accelerated end to end, senior people on the build from week one.

1

Frame

We dig past the brief to find the real bet. Who the user is, what the core loop should be, and the smallest v1 that can prove the hypothesis. You leave with clarity, not a feature list.

2

Shape

Product strategy, UX, architecture, and fixed pricing locked together. AI-accelerated research and prototyping compress 6 weeks of upfront design into 2. You sign off with a real plan, not a wireframe deck.

3

Ship

Senior engineers build in tight weekly cycles using AI-accelerated workflows. You see working software at every demo, not slide decks. We push back on scope creep before it eats the runway.

4

Compound

Launch with billing, auth, analytics, and feedback loops live from day one. We stay on as fixed monthly capacity to ship features and grow the product with real usage, not guesswork.

We have used Webhouse to help us develop our current booking system. They have been extremely great to work with, communicating well and they are very responsive.
Since the original development they have also finalised a new payment system integration along with Xero integration seamlessly. George and Ralph have been amazing to work with.
Would highly recommend using Webhouse.
