Invoice for free, receive e-invoices from Peppol for free and keep track of your company's money, profit and risks in real time. Your bank connects via API and payments are matched on their own, payment reminders go out automatically - and from 1 January 2027 you meet the new legal obligation without having to deal with anything.
Mandatory e-invoicing from 1 January 2027
The amendment to the VAT Act changes the way companies in Slovakia send each other invoices. A PDF by e-mail between VAT payers is no longer enough - the invoice has to go as a structured document through the Peppol network, and its data goes to the Financial Administration. The Bilvao app is ready for it today.
2026
Transition period - the ideal time to activate Peppol and try it out for real.
1 January 2027
Mandatory issuing and receiving of e-invoices within Slovakia (B2B and B2G).
1 July 2030
Planned abolition of the VAT control statement - the Financial Administration will already have the data from e-invoices.
2030
Gradual extension to cross-border invoices in the EU (the ViDA initiative).
This information is based on the amendment to the VAT Act passed in December 2025. It is not individual tax advice - we will gladly assess your specific situation.
