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 YouAAccttuuaallllyy NNeeeedd??
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
1. 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.
2. Design & Prototyping
Wireframes, user flows, and interactive prototypes, validated with you before development starts. You know exactly what you're getting.
3. 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.
4. Testing & Launch
Security testing, load testing, UAT with real users, and staged rollout. We don't push untested software.
5. 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 AskedQQuueessttiioonnss
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.
