One system, priced in writing before we start.

What you get

Need more than that? Your written price lists each extra and what it costs, before you decide.

Custom business software

One system built around your core workflow, live on your own domain.
from
NZ$7,999
live in weeks
Included
  • A working system built around your core workflow, live on your own domain
  • Logins for your team, one integration with a tool you already use, and an admin view
  • Something to click through in week one, and your team testing it with real work well before launch
  • Training for your team and 30 days of fixes once it is live

Why a senior team costs you less in the long run

AI can write an app in an afternoon. What it cannot do is decide how your data should be structured, what happens when two people edit the same job, or how the system copes in year three. That is the part our engineers own.

No juniors on your build.

Every engineer has ten or more years of shipping software behind them.

We never start from zero.

18 years of reusable components, with AI handling the repetitive setup.

Built for year three, not demo day.

Data, security and edge cases done properly, so it keeps working as you grow.

John Halvorsen-Jones, founder of Applicable

A founder signs off your price.

John Halvorsen-Jones, 30+ years in IT, reads every brief.

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, train your team and fix anything that comes up in the first 30 days.

Who comes to us

Sound familiar?

Four ways people arrive. One way we work: scoped, priced in writing, built by senior engineers.

A laptop crowded with a dozen app windows beside a pile of software invoices and sticky notes

“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.

An old beige desktop computer running a dated database form in a trade workshop office

“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.

A front-desk phone lifted mid-call while a hand notes order numbers beside a job status screen

“Our customers keep ringing to ask.”

Quotes, bookings, orders, job status. Give them a portal, and your phone goes quiet.

A laptop at a kitchen table at night showing code, an AI chat panel and a half-built app preview

“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.

Who you will deal with

You talk to the engineer building it, not to an account manager. John Halvorsen-Jones, our founder, prices every project and stays across it. And the office is real: Auckland, since 2008. Come in and see where your software is built.

Questions NZ businesses ask us

Most Applicable builds go live in a month. Reusable components and AI handle the setup, so our engineers spend their time on the logic, integrations and security.

Internal business tools, customer portals, legacy app modernisation, AI-enabled apps, mobile apps for Apple and Android, PWAs, loyalty programs, marketplaces, auction sites, payment solutions, gamification and subscription software.

Every build starts with the same base: an app with user sign-in and user management, plus three to five core features. 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$7,999 covers around 60 hours of design and development. Business applications (job tracker, quoting tool, CRM) from NZ$7,999; Legacy app modernisation from NZ$7,999; 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, let AI do the repetitive work, and put senior engineers only where judgement matters.

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$7,999.

Yes. We keep what works, fix the foundation (logins, data, security, hosting), and get it live. From NZ$7,999. You keep your code. Not sure it is worth saving? Start with an expert code review and remedy report for NZ$1,499.

Yes. One integration is included in every build. Extra ones are itemised in your written price.

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$499 a month for managed hosting, or NZ$2,499 a month for up to 40 hours of senior engineer time on new features, bug fixes and UI/UX improvements. Month to month.

Stop working around it

Tell us what your team keeps working around, or send the link to what you built. A senior engineer reads it and writes back with a price. If custom software is not the answer, we will say so.
