How to proceed


The company's accounts must be kept in accordance with a system of books and accounts that complies with the general rules of double-entry accounting.

This rule does not apply to traders who are natural persons and whose turnover for the last financial year, excluding VAT, does not exceed EUR 100,000.  

These traders can:

    • assets and rights of any kind;
    • liabilities, obligations and commitments of any kind;
