FIZ invoicing.
Free. Forever.

Our commitment

FIZ is the first software in Portugal that allows you to issue invoices in a truly free and certified way. It works. And it will keep working — free. Always.

No subscription

No limit on invoices or clients

No trial period

No fine print

Why is it free?

Because FIZ is the beginning of something bigger. We're building a complete platform for independent businesses. The invoicing module is free — and it will stay that way. Around it, we’ll launch new products:

  • smart business card

  • tax return submissions

  • automated accounting

  • certified and simplified accounting

and other useful tools for self-employed professionals

These services will be paid — but at half the market price. You activate only what you need, when you need it. Nothing is imposed. Nothing is hidden.

Simple and clear

Certified by AT

No limits

No surprises

Free. Forever.

FIZ. Period.

No tricks. No pressure. Just invoicing. Just free. It just works.
And with room to grow — at your own pace.
