When must I issue an invoice?

Within 15 days of the taxable supply date (Art. 71(1) EU VAT Directive / § 71(1) Slovak VAT Act).

What if the client does not pay?

After the due date you are entitled to statutory late-payment interest. You can enforce the invoice via a payment order or court proceedings.

Is an electronic invoice as valid as a paper one?

Yes. An electronic invoice is fully valid, provided its authenticity and integrity are ensured throughout the 10-year archiving obligation.

What is a variable symbol?

A variable symbol is a numeric payment identifier that allows the recipient to match a payment to a specific invoice. We recommend using the invoice number as the variable symbol.
