Estonian VAT invoice particulars, seven-year invoice retention in original form, and electronic issuance with recipient acceptance and authority-access boundary are reviewed from Tax and Customs Board sources. This generator does not route public-sector e-invoices or file VAT data. Simplified invoices, intra-Community references, special schemes and transaction-specific exceptions remain separate checks.
