Italian software house for companies that need custom software
Paracausality Systems is a software house based in Aversa, near Naples, Italy. We design and build websites, iOS and Android apps, business software and custom platforms for companies, businesses and startups, from process analysis to production release.
What we do
Why a software house instead of an off-the-shelf package
Off-the-shelf software makes the company adapt to the program. Custom software does the opposite: it starts from how you work today, removes manual steps and grows with you.
With a software house you have one partner for the whole project: analysis, design, development, release and maintenance. The same team that wrote the code stays on to look after the system after delivery.
Where we work
We are based in Aversa, between Naples and Caserta in southern Italy, and we work remotely with clients across Italy and abroad. Meetings happen on video calls and every step ends with something you can try.
How we work
Analysis
We meet the people who will use the software and map the processes. You get the requirements and a written quote.
Design
Architecture, data and interfaces before code, with a clickable prototype.
Development
Frequent releases to a staging environment: you watch the software grow.
Release
Data migration, publishing and staff training.
Evolution
Updates, security and new features as the company changes.

Frequently asked questions
Where is the software house based?
Our registered office is at Via Cicerone 31, 81031 Aversa (CE), Italy. We work with companies in the Naples and Caserta area and remotely with clients elsewhere.
What kind of projects do you take on?
Websites, e-commerce, iOS and Android apps, business software, SaaS platforms and system integrations. Some client work is under NDA and we show it on a call.

Tell us what the software needs to do using the guided quote or by booking a call. We reply within one business day.
How much does custom software cost?
It depends on features, number of users, platforms and integrations. We don't use price lists: after the analysis you get a detailed written quote, item by item.
