2027 marks an important milestone for e-invoicing in Europe. With new requirements taking effect in Germany and Norway, businesses must prepare for changes in how they create, exchange and process invoices. 

But what exactly is changing, and how can businesses prepare for the transition? 

Germany: Mandatory outbound e-invoicing from 2027 

Germany is introducing mandatory structured electronic invoicing for domestic B2B transactions through a phased approach. 

• 2025: Businesses within scope must be able to receive structured e-invoices. 

• 2027: Businesses with previous-year turnover exceeding €800,000 must generally issue structured e-invoices. 

• 2028: The issuance requirement extends to other businesses within scope, subject to applicable exemptions. 

Once the relevant transition periods end, traditional PDF invoices alone will no longer be sufficient. 

Invoices must comply with the European EN 16931 standard or meet the applicable interoperability requirements. Compatible formats include XRechnung, qualifying ZUGFeRD profiles and Peppol BIS Billing 3.0. 

For many businesses, the challenge goes beyond invoice formats. Existing ERP systems, delivery channels and invoicing workflows must also support the transition. 

Norway: New B2B e-invoicing requirements in 2027 

Norway is also introducing mandatory B2B electronic invoicing. 

From 1 January 2027, businesses within the relevant bookkeeping scope must issue structured electronic invoices for qualifying domestic B2B transactions, subject to transitional provisions. 

Recognised standards include EHF Invoicing and Peppol BIS Billing 3.0. However, transitional rules allow other qualifying structured formats until 2030. 

A further milestone arrives in 2030, when businesses must meet new requirements for digital bookkeeping and electronic invoice reception. 

For organisations operating in Norway, preparing for these changes means reviewing both outbound invoicing capabilities and existing accounting systems. 

E-Invoicing across Europe: What comes next? 

Germany and Norway are not isolated cases. Other European countries are also moving towards more digital invoicing processes, although their requirements differ. 

• Denmark: Digital bookkeeping rules require businesses within scope to use systems with electronic invoicing capabilities. 

• Sweden: E-invoicing is mandatory for relevant public-sector transactions, while broader B2B requirements remain under consideration. 

• Finland: Eligible businesses can request structured e-invoices from suppliers under existing legislation. 

At the European level, the VAT in the Digital Age (ViDA) framework introduces new digital reporting requirements based on e-invoicing for relevant intra-EU B2B transactions from 1 July 2030. 

Different countries, different timelines — but a common direction towards structured electronic invoicing and digital reporting. 

Why e-invoicing readiness goes beyond compliance 

Adapting to new regulations is not simply about replacing PDF invoices with XML files. 

Businesses need to consider four key areas: 

Invoice formats: Generate and process structured invoices that meet applicable requirements. 

Compliance validation: Identify format errors and support country-specific invoicing rules. 

Electronic connectivity: Exchange invoices through compatible networks and delivery channels. 

ERP integration: Connect electronic invoicing with existing financial systems and workflows. 

Addressing these challenges can help businesses reduce manual work while building more adaptable invoicing processes.
