Annual tax roll campaign Local government
Each year the public authorities prepared their tax rolls and bills with dozens of scripts and a different manual for each one.
From Ibiza, since 1987
Software that keeps the public sector and businesses running
We build and implement management software for the public sector, Microsoft Dynamics 365 Business Central for companies in any industry, and artificial intelligence that works inside both.

Artificial intelligence
AI in production, not in a slide deck
We use it ourselves first. Then we bring it to our clients with the same safeguards: the AI proposes, and a person approves what matters.
