EU invoicing is never just paperwork - one missing detail can block payments or trigger penalties. With EU rules, local variations, and incoming ViDA reforms, finance teams need absolute clarity. This guide gives it to you.
In the next few minutes you will:
Let us start with the building blocks that every invoice must carry.
Every EU member state follows the VAT Directive 2006/112/EC, but each country can add its own twists. The safest approach is to include all elements the Directive lists and then double-check local rules.
Mini case study: A French software publisher forgot to add the “self-billing” note required for the customer’s reverse charge in Germany. The German buyer refused payment until a corrected invoice arrived, delaying cash collection by three weeks.
Leaving any of these points out puts the supplier at risk of penalties and, worse, can block the customer’s right to deduct VAT. Summarizing: complete data equals smoother payments.

Paper is fading fast. Back in 2011, only 8.2 % of EU enterprises exchanged electronic invoices, and early estimates for 2013 placed e-invoice use at merely 4–15 % of all invoices. Fast-forward a decade: ViDA will make structured e-invoices and digital reporting the default across the Union by 2030.
Mini case study: An Italian engineering firm switched to the national SDI e-invoicing platform. Processing time per invoice fell from eight minutes to under two, saving thousands of euros annually.
For a practical overview of how e-invoicing laws and technologies interact and why structured data is key, read Benefits of E-Invoicing for Your Business.
Roughly 18 billion B2B and B2G invoices are sent each year, and about 3.24–5.4 billion of those go to public bodies. With ViDA, each member state must make its system interoperable by 2035, as agreed by the EU Council.
The takeaway: electronic invoicing is moving from optional to mandatory, and timelines differ by country. Always verify local go-live dates.

Penalties sit in national VAT acts. They vary but usually group into three buckets.
Mini case study: A UK retailer selling into Poland misapplied the local VAT rate and faced a 30 % surcharge on the unpaid tax, plus interest. The root cause was outdated rate logic in its ERP.
While sums differ, authorities share one view: ignorance is no excuse. Putting robust EU billing compliance checks in place pays off quickly.

VAT in the Digital Age(ViDA) is a major VAT reform. The reform is based on the three-pillar approach. It covers the modernization of the Single VAT Registration (SVR) scheme; the E-Invoicing and Digital Reporting Requirements (DRR) mandate for B2B intra-EU transactions; and the transformation of the tax rules for the Platform Economy.
Short checklist:
Many companies choose external support to keep up with the moving pieces.

Key takeaway: the earlier advisors are involved, the smoother the transition to mandatory e-invoicing and the lower the risk of penalties.
An EU-compliant invoice is a document, paper or electronic, that contains a unique sequential number, supplier and customer details, supply and invoice dates, accurate VAT breakdowns, and any legally required notes (such as reverse charge or margin scheme wording). From 2025 to 2035, structured e-invoices that adhere to EN 16931 will replace PDFs and paper across the Union under the VAT in the Digital Age reforms.
EU invoicing is shifting from static PDFs to structured, real-time data. Mandatory fields remain the backbone, but electronic formats and digital reporting are the future. Missing a field can cost money today; missing an electronic deadline could cost a market tomorrow. Whether you build in-house expertise or lean on trusted advisors, clarity, readiness, and agility will keep every invoice - and every payment - flowing.
Italy, France (from 2026), and Poland (from 2026) have published rules that require structured e-invoicing for domestic B2B sales, with several others announcing pilots.
The VAT Directive sets a minimum of ten years, but some countries, such as Hungary and Ireland, demand longer. Always check national legislation.
Not under ViDA. Only structured data files that allow automatic processing qualify as electronic invoices. A PDF counts as a digital copy of a paper invoice unless it carries an advanced electronic signature and meets integrity requirements.
Ideally during system selection or upgrade. Advisors can flag gaps before implementation, design compliant workflows, and train staff so errors do not reach customers or tax authorities.
Yes. For all taxable B2B transactions within the EU, an invoice is mandatory and must include the buyer’s VAT ID, the applicable VAT treatment (such as reverse charge), and all standard invoice fields. Some countries also require specific wording for intra-EU supplies. Always verify local rules to avoid deductibility issues or payment delays.
