Cross-border sales within the EU
Under the VAT in the Digital Age (ViDA) package adopted in 2025, structured e-invoicing and near real-time digital reporting become mandatory for intra-EU B2B supplies from 1 July 2030, with EN 16931 as the default standard. Since 2025, member states may also introduce domestic B2B e-invoicing mandates without asking the EU for a derogation.
Using InvoBox in Finland
InvoBox already opens incoming Peppol BIS Billing 3.0 XML files and shows them as a readable invoice. Issuing e-invoices for Finland is not available yet.
