IT support and custom software development.
One point of contact for both.

IT support

02
Software development
Web and mobile applications, CRM systems and AI automation. Built remotely, in your working hours, by the team that already runs its own products in production.

Questions
FAQ
We have no office in Croatia. Can you still help?+
For software development, yes. That work is done remotely, and our working day in Central European Time overlaps the whole EU. On-site IT support only makes sense if you have people or hardware in Zagreb or nearby.
What languages do you work in?+
English and Croatian. Documentation, tickets and calls in English, and Croatian towards local suppliers and authorities when that speeds things up.
How does invoicing work?+
CAUTUS SISTEMI d.o.o. is a Croatian limited company with an EU VAT ID, so you get a regular EU invoice. For companies registered for VAT in another member state the reverse charge applies.
How do we get a quote?+
Tell us about the project. We reply within 24 hours. We write the scope and the estimate, after a first call and at no charge.
