The Challenge DECO was paying $500,000 per year for an off-the-shelf CRM that couldn’t adapt as their business evolved. Every workaround cost time. Every limitation cost money. They needed software that worked the way they did — not the other way around.
The Solution Extranet Systems built DECO a fully custom CRM designed around their actual workflows, their team, and their growth plans. Built to evolve — not to lock them in.
The Outcome DECO now saves over $200,000 every year. Their CRM adapts as their business grows, giving them the infrastructure to scale without constraint — and without being held hostage to a vendor’s roadmap.

We start by listening. Requirements gathering shapes everything that follows. Then we design, build, test, deploy, and stay with you to keep your software evolving as your business grows.
We dig into how your business actually works. The workflows, the friction points, the goals. From there, we map the solution, agree on scope and success metrics, and shape a build plan with no surprises down the track.
Our developers bring it to life with clean code, regular check-ins, and rigorous testing at every stage. Once you’re live, we handle hosting, maintenance, and ongoing improvements so your software keeps pace with your business.
From web and mobile to enterprise systems — we build software that fits your business at every scale.
New software doesn't exist in isolation. We connect it to your existing systems so data flows freely and nothing breaks in the process.
