Senior engineers only
Tell us what you need to build / fix
Enter your contact details below and we'll take you straight to a short brief where you tell us what you're trying to build or fix. A senior consultant will then respond with feedback and an estimate.
Senior developers, working with AI.
Experienced engineers use AI to build faster, so you get custom software sooner and for less. A person checks every line before it ships.
No juniors on your build.
A senior engineer is on your project from the first brief to launch, and reviews every line that ships.
We never start from zero.
18 years of reusable components, and AI to build faster. A person checks every line before it ships.
Built for year three, not demo day.
Data, security and edge cases done properly, so it keeps working as you grow.
Our founder reads every brief.
John Halvorsen-Jones, 30+ years in tech, reads every brief and calls back within 48 hours.

From problem
to live system
What you want to build.
The workaround, the old system, the half-finished AI app. Plain English is fine.
Get the price in writing.
A senior engineer scopes it and puts one number on it. Nothing gets added without your say-so.
Test as we go.
Something clickable in days. Your team tries it with real work before we call it done.
Go live.
We move your data across and hand over the code, the hosting accounts and the content system in your name.
Sound familiar?
Four ways people arrive. One way we work: scoped, priced in writing, built by senior engineers.
“We pay for software we barely use.”
Several subscriptions, a pile of workarounds, per-seat costs that climb every year. One system, one login, only the parts you need. Job management, quoting, CRM, inventory, dashboards.
“Our business runs on a 15-year-old app.”
Windows, DOS or Access, and one person who knows how it works. We modernise it for the browser and keep your data and workflows.
“Our customers keep ringing to ask.”
Quotes, bookings, orders, job status. Give them a portal, and your phone goes quiet.
“I built it with AI and got stuck.”
Lovable, Bolt, Replit or Cursor got you a demo. We fix the foundation and get it live for real users. Not sure what you have? Start with an expert code review for NZ$1,499.
Past work for New Zealand businesses
Named clients, real systems. Each case study says what was built and what changed.

Questions NZ businesses ask us
Most Applicable builds go live in weeks, not months. Reusable components and AI handle the setup, so our engineers spend their time on the logic, integrations and security. The number of weeks is in writing before we start.
Internal business tools, customer portals, legacy app modernisation, AI-enabled apps, mobile apps for Apple and Android, PWAs, loyalty programmes, marketplaces, auction sites, payment solutions, gamification and subscription software.
Every build starts with the same base: an app with user login, role based access control and user management, plus up to four main features across up to 15 screens and modals. Think messaging, task management, payments, catalogues, notes, digital forms, admin and analytics. We size your app in the first briefing, and the time it needs sets the price. As a guide, NZ$6,999 covers around 60 hours of design and development. Business applications (job tracker, quoting tool, CRM) from NZ$6,999; Legacy app modernisation from NZ$6,999; Customer applications (portals, booking services) from NZ$8,999; Mobile applications (Apple and Android) from NZ$11,999; Subscription software with billing from NZ$16,999; expert code review and remedy report for existing apps NZ$1,499. What moves the price: more features, extra integrations, more user types, and data from an old system. Your exact price comes in writing before any work starts.
Agencies bill for setup work we did years ago. We start from 18 years of reusable components and experienced engineers who use AI to build faster, so you get the software sooner and for less. A person checks every line before it ships.
Yes. One system with only the parts you use, one login for everyone, connected to the tools you keep.
No. Most people come to us with a problem, not a spec. A senior engineer asks the questions and turns it into a scope and a price.
Yes. We rebuild it for the browser, move your data across without a rekey, and keep the old one running until the new one is proven. From NZ$6,999.
Yes. We keep what works, fix the foundation (logins, data, security, hosting), and get it live. From NZ$6,999. You keep your code. Not sure it is worth saving? Start with an expert code review and remedy report for NZ$1,499.
Yes. Integrations are scoped and quoted per project, and each one is itemised in your written price before we start.
You do, 100 percent, once the build is paid for. The designs and IP too.
We keep working until it matches the written scope, before we send the final invoice.
Nothing if you host it yourself. Or NZ$249 a month for managed hosting, or NZ$1,599 a month to add bug fixes, UI/UX improvements and new features on top. Month to month, and bigger projects are quoted separately.
Stop working around it
Tell us what your team keeps working around, or send the link to what you built. A senior consultant responds with feedback and an estimate. If custom software is not the answer, we will say so.
“John and his team have been ahead of timeline, under budget and transparent for the duration of our projects.”
“It was so quick and easy to update the website with new content this morning; such a change from the usual process.”
“John and Applicable went the extra mile to deliver the solution required.”
