Custom Software Development
Sometimes a website isn't enough. When you need a customer portal, an internal tool, a booking system, or two systems that need to talk to each other, we design and build software that fits your business - not the other way around.
Web applications
Customer portals, dashboards, booking and quoting tools, member areas - built with modern, maintainable technology that's fast for users and easy to extend later.
Integrations
Connect the tools you already use - Xero, Shopify, HubSpot, Vend and Lightspeed, Trade Me, payment gateways and more - so data flows automatically. No more double-entry, copy-paste or spreadsheets holding things together.
Automation
Replace slow manual processes with automated workflows - quotes, invoices, notifications, reporting - freeing your team to do the work that actually needs a human.
Built to last
Clean architecture, sensible documentation and proper testing from someone who's built mission-critical systems for banks and government - so your software keeps working as you grow.
Technologies we use
- TypeScript
- Node.js
- React
- Vue
- Java / Spring Boot
- .NET / C#
- Python
- REST & GraphQL APIs
Custom software development in Auckland, for all of New Zealand
If you’ve searched for custom software development in Auckland or a web app developer in NZ, you’ve probably found two extremes: offshore outfits with no local accountability, and big consultancies with eye-watering day rates. Long White Digital sits deliberately in between - an Auckland studio with enterprise experience (banking, government, healthcare, airline systems) that works at small and medium business scale.
We build the software that sits behind your business: customer portals, quoting and booking systems, internal dashboards, and the integrations that make your existing tools talk to each other.
When custom software is the right call
Off-the-shelf software is the right answer more often than developers like to admit - and we’ll tell you when it is. Custom makes sense when:
- Your process is your edge. The way you quote, schedule or serve customers is different from everyone else, and generic software forces you to work its way instead.
- You’ve outgrown spreadsheets. The business runs on one giant Excel file that only one person understands, and a mistake in it costs real money.
- Your systems don’t talk. Staff re-key the same data into Xero, your job system and a spreadsheet. An integration removes the double-handling and the errors.
- The off-the-shelf option costs more long-term. Per-seat SaaS pricing across a growing team often overtakes the cost of a one-off build within a couple of years.
If none of those sound like you, we’ll say so on the first call - it’s free, and honest advice is the cheapest thing we offer.
What we build
Web applications. Customer portals, member areas, quoting and booking tools, admin dashboards. Built on modern, boring-in-a-good-way technology (TypeScript, React or Vue, Node.js or .NET) that any competent developer can pick up later - no lock-in to us.
Systems integration. Xero, HubSpot, Shopify, payment gateways, freight and logistics APIs, government systems. If it has an API, we can usually connect it - and if it doesn’t, we’ve dealt with worse.
Automation. Quotes that generate themselves, invoices that send on job completion, reports that land in your inbox Monday morning. Automation projects are usually the fastest payback of anything we do.
How we’re different from a typical dev shop
Most of our career has been spent on systems where failure makes the news: airline reservations, banking payments, AML compliance platforms. That background shows up in the details - proper testing, security by default, documentation, and infrastructure that doesn’t fall over. You get that rigour at a studio price, from someone you can meet in Auckland, on a fixed quote with no surprises.

Frequently asked questions
I have an idea but I'm not technical - can you help?
That's exactly who we work with. We start by understanding your problem in plain language, then propose the simplest solution that solves it. No jargon, no over-engineering.
Can you integrate with the tools I already use?
Most likely, yes - Xero, HubSpot, Shopify, payment gateways, government APIs and many more. If a system has an API, we can usually connect to it.
Do you offer support after launch?
Yes. We offer ongoing support and improvement plans so your software stays secure, up to date and evolving with your business.
How much does custom software development cost in NZ?
Small tools and integrations typically start around $5-15k. Web applications with user accounts, dashboards or portals usually land in the $15-60k range depending on complexity. We quote fixed prices after a free scoping call, so you know the number before any work starts.
How long does a custom web application take to build?
A focused internal tool or integration is often live in 2-6 weeks. A customer-facing web application typically takes 2-4 months from kickoff to launch. We ship in stages, so you see working software early - not a big reveal at the end.
