Good questions

Before you invite a duck into your books.

What happens when my update year ends?

Nothing dramatic. Quacky keeps working exactly as it did. Renew only when you want another year of updates.

Does Quacky submit taxes or connect to the AEAT?

No. It prepares useful quarterly figures and estimates, but it does not file returns and is not a full Veri*factu implementation.

Can I use Quacky without internet?

Yes. Your day-to-day work is fully local. Internet is only needed to activate or periodically validate a license and download updates.

Where is my data stored?

In a local SQLite database on your computer. You control automatic backups and can export invoices and expenses to CSV.

Ready when you are

Clear the paperwork. Get back to your work.
