FAQ

Is it really free?

Yes. Everything is free right now, no card needed. If we ever introduce paid plans, we will tell you 30 days in advance.

Where is my data?

On servers in the EU (Germany). We never sell data, and you can export your invoices and contacts at any time.

Does it suit non-VAT payers?

Yes, it is built mainly for sole traders, both VAT payers and non-payers. Invoices contain every detail Czech law requires.

How do I move from iDoklad?

In Settings → Import from iDoklad, run the prepared script and upload the file. Your invoices, contacts and numbering are then here.

Does Dokkio handle the data box and taxes?

They are on the way: the data box with letter translation, self-employed taxes and EET 2.0. Sign up now and the new features will simply appear.

Is it for foreigners too?

Yes. The app and invoices are in Czech, English, Ukrainian and Russian, and the bot replies in your profile language.
