Custom web applications, portals and business systems that grow with your company

From CRM systems and internal automation to portals handling millions of visits — software designed around your processes, not the other way around.

  • 20+ years of development
  • 200+ projects delivered
  • 50+ long-term partnerships

Your business isn't generic. Why should your software be?

Off-the-shelf SaaS forces you to compromise: you change your processes to fit the tool's limitations, pay a growing monthly bill, and lock yourself into a single vendor.

We do the opposite — we build the system around the way you work.
The result? Full control. No compromises. No vendor lock-in.

Common problems with off-the-shelf tools

  • Monthly subscriptions that grow with every new user
  • Processes adapt to the tool, not the other way around
  • Vendor dependency and costly data migrations

Why ADiSoft

20+ years of active development

We started in 2005. Since then we have delivered over 200 projects for clients in Croatia, Austria, Germany and Italy. Some of our systems have been running continuously for more than 15 years.

Tailored approach to every project

We don't sell pre-packaged solutions. Every project starts with understanding your specific needs and designing a system that fits exactly what you do.

Long-term partnership

Our clients stay with us for years. We maintain portals with hundreds of thousands of annual visits, and continuously develop and extend their systems.

End-to-end from one team

From the initial idea, through development, to launch and maintenance — we handle all of it. One point of contact, one accountability line.

What our clients say

Voices from the people we have been working with for years.

"Our processes were scattered across spreadsheets and emails — ADiSoft pulled it all into a single custom system. The application tracks our quotes, clients, and project records, and the team is always there when we need an upgrade or support."

Nedžad Biser Managing Director, Badiemari GmbH

"ADiSoft built a portal that handles thousands of listings, automatic imports from partner agencies, and a fully multilingual interface. The system has been running flawlessly for years, even at peak season — and all without off-the-shelf templates."

Azra Valjevac Director, Alma Dom

How we work

A transparent process from idea to finished product.

  1. We understand your needs

    We start with a thorough analysis of your business processes, goals and pain points. The focus is on understanding the problem and the business case for solving it.

    Outcome:

    A clear picture of your needs and an honest assessment of whether custom development is the right choice for you.

  2. We plan the solution

    We design a system architecture that solves your real problems. We deliver a detailed specification, wireframes, cost estimate and timeline.

    Outcome:

    A document that clearly states what you will get, what it costs, and how long it will take.

  3. We build and test

    We build your application step by step. We keep you informed of progress and thoroughly test every feature before moving on. Quality before speed.

    Outcome:

    A stable application that works the way you envisioned, tested in real-world scenarios.

  4. We launch and support

    We deploy the system to production and ensure smooth data migration where needed. After launch we don't disappear — we stay on board for support and continued development.

    Outcome:

    Your system is live and you have a partner for the long term.
