About us

Italian business software, built for invoicing in Italy

Nanus starts from a simple idea: Italian electronic invoicing is complex, but the software that handles it should not be. It is developed by Maingage S.r.l. in Apulia, with an obsessive attention to tax rules and to the time of the people who use it.

What guides us

Four principles, on every screen

Rules come first

Every check is based on the FatturaPA specifications and the official list of SDI checks. When the Revenue Agency changes something, Nanus is updated.

Complete, yet simple

Real business software, with inventory, orders, sales agents and accounting. Everyday features are front and centre; the rest is there without getting in the way.

Your data is yours

Bring it in from any software and take it out whenever you like, in open formats. No hidden lock-in.

Wherever you work

In the browser, on your computer even offline, and on your phone, with the same data and the same interface.
