Mandatory e-invoicing in Sweden
Sweden has been one of the pioneers of digital invoicing in Europe. Electronic invoicing in the public sector (B2G) has been mandatory since April 1, 2019. Since then, all suppliers to the public administration must send invoices in a structured electronic format.
The system follows the European standard EN 16931, enabling automatic processing and improving efficiency in public sector accounting and procurement processes.
In B2B transactions, e-invoicing is not yet mandatory. However, it is widely used by businesses across Sweden, especially in cross-border trade. Swedish authorities are currently assessing the potential introduction of mandatory e-invoicing and digital reporting for domestic B2B transactions, as part of the EU’s VAT in the Digital Age (ViDA) initiative.
Our solution enables companies to issue and receive compliant e-invoices in Sweden, ensuring seamless integration with existing business systems and future regulatory requirements.
E-invoicing standards in Sweden
The Swedish e-invoicing ecosystem is decentralized and based on structured formats compliant with the EN 16931 European standard. Electronic invoices are exchanged through interoperable networks and service providers.
Key components of the system include:
- Peppol network – the primary infrastructure used for exchanging e-invoices in B2G transactions and increasingly in B2B,
- Peppol BIS Billing 3.0 – the standard format required for electronic invoices in the public sector, compliant with EN 16931,
- Peppol Access Points – certified service providers enabling secure transmission of e-invoices between companies and public institutions,
- Structured XML formats – ensuring machine readability and automatic processing within ERP and accounting systems.
Our solution supports Peppol connectivity and EN 16931-compliant formats, helping businesses exchange invoices securely and remain prepared for future e-invoicing regulations in Sweden and across the EU.
- Will foreign entities registered for VAT in Poland also be required to issue e-invoices?
- Will all sales invoices need to be issued as e-invoices, or only those for domestic contractors?
- Will it be possible to send invoices (individually or in bulk) without using the API, via an interface accessible to employees?
- Will an invoice issuer be able to download an invoice image from KSeF to print or send it to a contractor via email?
- How will attachments to invoices, such as energy consumption reports or protocols, be delivered to contractors?
- Can the invoice storage period be extended, and if not, how should invoices be stored after 10 years?
