Document format and locale facts for Sweden

Document vocabulary and checks

Core Swedish VAT invoice and correction particulars, seller identification, seven-year record retention, and the public-procurement structured eInvoice boundary are reviewed from Skatteverket and Digg. Simplified invoices, ROT/RUT, exemption, reverse-charge and sector-specific cases remain transaction-specific checks.
