E-invoicing requirements in the EU: What businesses need to know now.

Authored by: Vera Görtjes, MSc – VAT & Excise Manager, Gaston Schul

What exactly is e-invoicing?

E-invoicing is the electronic exchange of structured invoice data between suppliers and customers and is distinct from real-time tax reporting. Unlike a PDF sent by email, an e-invoice is created, transmitted, and processed in a standardised format – typically XML or UBL – and often exchanged via frameworks such as PEPPOL BIS.

The benefit? These invoices can be read automatically by accounting and ERP systems, eliminating manual work, reducing errors, and ensuring full traceability.

Why is e-invoicing such a hot topic?

E-invoicing is climbing higher on every business agenda, not only because it is being mandated by governments, but also because it reshapes how businesses manage VAT compliance and unlocks new efficiencies in operational processes. The three main factors driving this shift are:

• Government mandates: Countries across Europe are introducing mandatory e-invoicing as part of their VAT strategies. Italy has led the way, with other countries already following or set to roll out staged implementations in the coming years.
• VAT compliance: Structured, standardised e-invoices provide authorities clearer data and stronger audit trials. This reduces fraud, closes the VAT gap, and means compliance increasingly depends on having the right invoicing processes.
• Business efficiency: Beyond compliance, e-invoicing delivers practical benefits – faster processing, fewer errors, and stronger cashflow control.

Developments across Europe

Across Europe, e-invoicing is shifting from isolated national initiatives to a coordinated EU-wide approach to VAT compliance. With the European Commission’s VAT in the Digital Age (ViDA) initiative, formally adopted on 11 March 2025, the EU has established a unified framework for e-invoicing. Crucially, ViDA sets a clear timeline: mandatory cross-border B2B e-invoicing will apply from 1 July 2030. Several Member States have already set firm timelines for mandatory adoption. This is where things stand today:

• Italy: E-invoicing in place since 2019.
• Romania: B2B e-invoicing mandatory from 2024, B2C will follow from 1 January 2025.
• France: Phased rollout for e-invoicing starting September 2026.
• Poland: National e-invoicing platform expected in 2026.
• Germany: Receipt of e-invoices required from 2025; issuance obligations phased in from 2027.
• Spain: Plans for mandatory e-invoicing in 2026/2027

The trend is clear: structured e-invoicing is becoming the European standard, and businesses that act early will be best prepared.

How you can prepare for mandatory e-invoicing in Europe

If you’re operating across Europe, e-invoicing is no longer something to keep on the long-term horizon – it is fast becoming a regulatory requirement that demands early preparation. My advice is to start preparing now, not only to reduce compliance risks but also to benefit from smoother, more efficient invoicing processes. Here are five steps I recommend:

1. Check readiness: Can your ERP, billing and AP systems issue, receive, and archive structured e-invoices?
2. Adopt the right standards: For example, PEPPOL is being widely adopted across Europe – ensure your systems are compatible.
3. Plan for cross-border complexity: Build a country-by-country matrix covering formats, platforms, registration requirements, go-live dates, and any transitional rules.
4. Strengthen controls: Align master data, VAT determination and electronic archiving policies.
5. Act early: Transitioning ahead of deadlines and pilot with key customers reduces risk and creates efficiency gains sooner.

Final thoughts: E-invoicing as both obligation and opportunity

E-invoicing is no longer an IT side project – it is a compliance necessity under Europe’s mandatory e-invoicing rules. Businesses that fail to prepare risk serious consequences: rejected invoices, delayed payments, fines from tax authorities, and even restrictions on their ability to trade cross-border.

But preparing early doesn’t just help you avoid penalties. It also unlocks significant efficiency gains: faster invoice processing, fewer manual errors, real-time insight into VAT data, and improved cashflow through quicker payment cycles. For finance teams, this means more time to focus on strategy instead of administration – and for businesses overall, it strengthens both compliance and competitiveness.
