よくある質問

Are finance calculators free?

Yes — finance helpers on Tentaco are free to use in the browser without creating an account for standard modes.

Do you store my loan inputs?

Local finance modes keep numbers in the tab. Tentaco does not save your loan scenario unless a mode explicitly offers cloud save.

Where is e-invoicing?

For XRechnung, ZUGFeRD and related DE/EU invoice tools, open the e-rechnung hub linked from finance workflows.
