Do you actually need an app?
Many businesses ask for an app when a faster website, a customer portal or an automation inside Microsoft 365 would do the job for a fraction of the cost. We will tell you honestly which option fits. An app usually makes sense when:
- Customers use it repeatedly, such as bookings, ordering, loyalty or account access.
- Staff work in the field and need job sheets, photos, signatures or checklists that work offline.
- You need phone features such as the camera, GPS, push notifications or barcode scanning.
- A manual process is costing hours each week and paper or spreadsheets are causing errors.

How an app project works
Discovery
We map the problem, the users and the must-have features, and recommend whether an app, web app or simpler tool fits best.
Scope and quote
You receive a written scope, timeline and fixed quote, ex GST with GST shown separately. No surprises at the end.
Design and prototype
You click through a working prototype and sign off the screens before development starts.
Build and test
We build in stages and share test versions on your own phone, so you see progress every step.
Launch
We handle app store submission, privacy details and go-live.
Support
Optional monthly support keeps the app working as Apple and Google release new versions.
Security built in
As an IT and cyber security provider, we build apps the way we would want our own business data handled. That means secure sign-in with multi-factor authentication where it fits, encrypted data in transit, the minimum personal information collected, and a privacy approach aligned with the Australian Privacy Principles.

Frequently asked questions
How much does an app cost?
It depends on the number of screens, user types and integrations. A simple internal app costs far less than a public app with payments and accounts. After a discovery session we give you a fixed quote, ex GST, so you know the cost before work starts.
How long does it take to build an app?
Small internal apps can take a few weeks. Customer-facing apps with accounts, payments and integrations usually take a few months, including design, testing and app store approval. Your quote includes a timeline.
Do I need separate iPhone and Android apps?
Usually not. For most business apps we recommend one shared codebase that runs on both iPhone and Android, which lowers build and maintenance costs. We only recommend separate native apps when a feature genuinely needs it.
Can you update an existing app?
Often, yes. We review the existing app first, then recommend whether to update it or rebuild, with a fixed quote ex GST.
