Custom Web App Development in NZ - SaaS Platforms, Business Tools & Portals Built to Scale
If your business runs on manual processes, spreadsheets, or software that almost does what you need - a custom web app might be the thing that changes how your team works. We build web applications for NZ businesses: booking platforms, wholesale portals, property management tools, SaaS products. Built properly, on architecture that scales.
What Is A Web App?
Is a Web App What YouActually Need?
A web app is software that runs in a browser more powerful than a website, more accessible than a native app. Your users don't install anything. They log in and work.
You probably need a web app if you're dealing with:
Manual workflows your team does daily that could be automated
A process that currently lives in a spreadsheet and is starting to cause problems
Data that needs to be accessed, updated, or reported on by multiple people
A business idea that requires user accounts, subscriptions, or a backend
A customer portal, booking engine, admin dashboard, or internal operations tool
If a website solves your problem, we'll tell you that. If you need a web app or if you're not sure a 30-min call usually makes it clear.

How We Work
From Brief to LaunchThe Web App Journey
Discovery & Architecture
We map your requirements, user roles, data model, and integration points before anything is designed or built. Getting the architecture right early saves weeks later.
Design & Prototyping
Wireframes, user flows, and interactive prototypes - validated with you before development starts. You know exactly what you're getting.
Development in Sprints
Agile sprints with working software at the end of each. You review real features - not slides. Feedback happens while it's still cheap.
Testing & Launch
Security testing, load testing, UAT with real users, and staged rollout. We don't push untested software.
Post-Launch Support
Ongoing maintenance, feature additions, and monitoring. We're still accountable after go-live. Maintenance from $200/month.

What We Build With
We use modern, battle-tested frameworks, not whatever we happen to know best.
Chosen based on your performance requirements and whether the app needs server-side rendering.
REST or GraphQL APIs, designed for the integrations your app needs.
Structured based on your data model, not a default.
Deployed properly, monitored, and backed up. 99.9% uptime on infrastructure we've shipped.
And anything else your business runs on.

Frequently AskedQuestions
How long does a web app take to build?
A focused MVP: 10-14 weeks. A full platform with multiple user roles, backend, and integrations: 4-6 months. We scope this at the start and build a timeline you can plan around.
What if I don't have a full spec?
Most clients don't - and that's fine. We work through discovery with you to define what needs to be built, then scope it precisely. You'll have a fixed quote before development starts.
Can you integrate with our existing systems?
Yes. Xero, MYOB, Salesforce, HubSpot, Stripe, Trade Me - we build integrations for the tools your business already runs on. See our API integration services.
Will the app handle growth?
We build for scalability from the start - horizontal scaling, proper database design, caching, and infrastructure that doesn't need a full rebuild when you add 10x the users.
Can I add features after launch?
Yes, and most clients do. We build with future development in mind - clean code, documented APIs, and architecture that makes adding features straightforward rather than a hack.
What about security?
Proper security isn't optional. We build with OWASP standards, implement authentication correctly, conduct security testing pre-launch, and can include ongoing vulnerability monitoring.
