What is an expense?

They are accounted for as expenses the ones arising from the self-employed person's economic activity for which a simplified invoice is available as proof, instead of an ordinary invoice, and provided that the amount does not exceed 400€ (VAT included).

Its main difference from ordinary invoices is that it usually does not include the information of the recipient, but only that of the sender. VAT may be included or broken down.
