Custom software and app development for Australian businesses

avissoft builds custom software for small and medium businesses: CRM systems, online stores and shopping carts, Android apps, web portals and system integrations. Every project is scoped and quoted upfront at a fixed price.

What we build

Custom CRM systems

Track customers, leads, quotes, jobs and follow-ups in one place, built around how your business actually works instead of forcing you into an off-the-shelf tool.

Online stores and shopping carts

Sell products or services online with secure payments, stock management, shipping options and order notifications.

Android apps

Apps for your customers or your team, from booking and ordering apps to field-service and job-tracking tools.

Web portals and business systems

Customer portals, booking systems, quoting tools, staff dashboards and internal admin systems.

Integrations and automation

Connect your website, CRM, accounting, payments and email so data flows automatically and you stop re-typing it.

How custom projects work

1. Free discovery call: tell us what you need and what is not working today.
2. Fixed-price proposal: a written scope, timeline and price before any work starts.
3. Build in stages: you see progress regularly and give feedback along the way.
4. Launch and support: training, handover, and ongoing support if you want it.

Frequently asked questions

How much does custom software cost?

It depends on the scope. Small tools and integrations can start from a few thousand dollars, while full CRM systems or apps are larger projects. Every project gets a fixed-price written quote first.

Do I own the code of my custom software?

Yes. Once the project is paid in full, the code and data belong to your business.

How long does a custom software project take?

Small integrations can take a few weeks; larger CRM systems or apps take longer. You get a timeline in your written proposal before any work starts.
