E-invoicing has been part of Sweden public sector landscape for well over a decade, and the country is now in the process of extending its digital invoicing framework to the private sector. For businesses operating in Sweden, understanding what is currently required, what is genuinely recommended, and what is coming is essential for both compliance and operational readiness.
What E-Invoicing Actually Means
E-invoicing is frequently misunderstood. Sending a PDF invoice by email is not e-invoicing, despite being electronic. True e-invoicing involves the exchange of invoices in a structured, machine-readable format that allows the receiving system to process the data automatically, without manual re-entry. The invoice data is transmitted directly between the supplier’s and buyer’s accounting systems, typically through a dedicated network.
In Sweden, the applicable standard is EN 16931, the European e-invoicing standard. The recommended transmission channel is the Peppol network, a secure interoperable infrastructure used across Europe and beyond. The specific format in use is Peppol BIS Billing 3.0, which Sweden implements directly from the OpenPeppol specification without national adaptations.
Current Legal Requirements in Sweden
Sweden e-invoicing mandate currently applies to public sector transactions. The rules stem from the Act on Electronic Invoicing in Public Procurement (2018:1277), which implements EU Directive 2014/55/EU. Since 1 April 2019, all Swedish public sector entities, including central government agencies, municipalities, and regions, are required to be able to receive and process structured e-invoices compliant with EN 16931.
In practice, this means that any business supplying goods or services to Swedish public authorities must issue structured e-invoices through the Peppol network. Paper invoices and PDF invoices are not accepted for public procurement contracts above EU thresholds. From December 2019, all contracting entities in the public sector were required to register on Peppol.
For private sector (B2B) transactions, e-invoicing remains voluntary as of 2026. There is no current mandate requiring businesses to issue or receive structured e-invoices in commercial transactions, though mutual agreement between parties to use electronic formats is common and increasingly expected by larger buyers.
The Transition Away from Legacy Formats
Sweden has a long history of electronic invoicing, which means many businesses are still using older formats such as Svefaktura or EDIFACT. These formats are progressively being phased out. Since mid-2025, SFTI (Single Face To Industry, the Swedish initiative for e-procurement standardisation) has been requiring that all new public procurement projects use Peppol BIS Billing 3.0. Businesses that have not yet migrated their public sector invoicing infrastructure to Peppol should treat this as a priority.
Why Adopt E-Invoicing Beyond Compliance
For businesses that have not yet moved beyond paper or PDF-based invoicing in their B2B operations, the operational case for structured e-invoicing is substantial:
- Automated processing: Invoices received in a structured format feed directly into the accounting system. Most modern Swedish accounting platforms, including Fortnox, Visma, and Hogia, support Peppol-based e-invoicing natively, allowing automatic posting or AI-assisted coding suggestions.
- Reduced error rates: Structured data transfer eliminates manual re-keying, which is a primary source of invoicing errors and the discrepancies that trigger payment delays.
- Audit readiness: Digitally processed invoices are easier to retrieve, verify, and present during tax audits. Sweden requires invoices to be archived for seven years, and digital archives are far more manageable than paper-based equivalents.
- Public sector access: Any company wishing to supply the Swedish public sector must be Peppol-capable. Given the size of Sweden’s public procurement market, this alone is often a decisive reason to adopt structured e-invoicing.
- Future-proofing: With mandatory B2B e-invoicing expected to follow from EU-level legislation, investing in Peppol infrastructure now avoids a more disruptive transition later.
What Is Coming: ViDA and the 2026 National Inquiry
The most significant development on Sweden’s e-invoicing horizon is the EU’s VAT in the Digital Age (ViDA) directive, adopted in March 2025. ViDA introduces mandatory digital VAT reporting based on structured e-invoices. For cross-border B2B transactions, the requirement is set to apply from 1 July 2030. EU Member States must transpose the directive into national law, and may also choose to extend mandatory e-invoicing to domestic transactions.
On 5 February 2026, the Swedish Ministry of Finance formally launched a national inquiry into how ViDA should be implemented in Swedish law. A commissioner has been appointed to examine the necessary legislative changes, assess whether domestic B2B e-invoicing should also be mandated, and consider how Skatteverket (the Swedish Tax Agency) may use e-invoicing data for VAT administration and fraud prevention. The inquiry’s findings are due no later than 30 November 2027.
In parallel, the Swedish Agency for Digital Government (Digg), which currently serves as Sweden’s Peppol Authority, is being merged with the Post and Telecom Authority (PTS). The merged organisation, expected to be operational by 1 January 2027, will assume responsibility for overseeing Sweden’s Peppol infrastructure and coordinating with the broader European e-invoicing framework.
While the timing and precise scope of a domestic B2B mandate remain subject to the inquiry’s conclusions, the direction of travel is clear. Swedish tax authorities, business federations, and EU policy are all aligned around structured e-invoicing as the future standard for commercial transactions.
Practical Steps for Businesses
Regardless of whether a company currently supplies the public sector, the following steps are worth taking now:
- Verify that your accounting software supports Peppol BIS Billing 3.0 and that your Peppol access point registration is active and up to date.
- If you are still using legacy formats such as Svefaktura or EDIFACT for public sector invoicing, plan a migration to Peppol BIS 3.0 without delay.
- For B2B invoicing, consider notifying key suppliers that you are moving to structured e-invoice receipt, which will reduce processing time and manual handling on both sides.
- Monitor the progress of the ViDA inquiry, as the commissioner’s recommendations in late 2027 will determine the timeline and scope of Sweden’s domestic B2B mandate.
