What is e-invoicing?

E-invoices (electronic invoices) are invoices issued, transmitted, and received in a structured electronic format (such as XML or UBL) that allows for automatic and electronic processing, as required by EU Directive 2014/55/EU.

The move towards e-invoicing aims to recover more than €11 billion in VAT per year by reducing paper-based records, promoting digital signatures and preventing tax evasion and fraud.

It’s safe to say most businesses are embracing digital transformation. Yet we still hear stories of finance teams who print out and handle practical paper copies of invoices, risking data leaks, duplicate work and information bottlenecks.

E-invoicing rules are a bid to make businesses more efficient – and their data more accurate. And of course, there’s the need to be compliant with the laws already in place or shortly on the way.

Regulations are already in place across much of mainland Europe, but the exact details vary. Keep reading to find out how your business will be impacted and what steps to take to stay compliant.

In Denmark, e-invoicing is mandatory for all Business-to-Government (B2G) transactions, enforced through the NemHandel network using OIOUBL 2.1 or Peppol BIS 3.0 standards. B2B e-invoicing is not yet mandatory. However, under the 2022 Bookkeeping Act, all businesses must use digital systems capable of receiving and archiving electronic invoices by Jan 1, 2026.

How to prepare your business for e-invoicing

Compliance with e-invoicing regulations doesn’t have to be overwhelming. By following these steps, your business can stay ahead of deadlines, reduce errors and take full advantage of digital invoicing benefits:

1. Audit your current invoicing process: Identify how invoices are issued, received and processed today. Note any manual steps or inefficiencies that could cause delays or errors.
2. Choose an accredited e-invoicing platform: Ensure your software is certified or accredited by the relevant national authority (e.g., Chorus Pro in France, ZUGFeRD/XRechnung in Germany) and compliant with local regulations.
3. Map internal workflows and responsibilities: Define who will issue, approve and archive invoices. Update policies to reflect digital processes and ensure everyone is on the same page.
4. Train your finance team: Make sure staff understand how to issue and process e-invoices correctly. Run a few test transactions before going live to catch issues early.
5. Monitor local regulations and deadlines: E-invoicing rules are evolving, so stay informed via official tax authorities or industry updates. Adjust your processes promptly if any deadlines or requirements change.
6. Start early: Don’t wait until the last minute – especially if your business is in a country with imminent deadlines. Early adoption reduces risk and gives your team time to resolve technical or operational challenges.

Pro tip: Treat e-invoicing as more than compliance – it’s an opportunity to streamline your finance operations, reduce errors and improve cash flow visibility.

Final thoughts

E-invoicing represents both a regulatory necessity and an opportunity for finance teams to modernise operations. Whilst the rules may seem complex, taking a structured approach – auditing current processes, adopting compliant technology, training teams and monitoring changes – makes compliance manageable and positions your business to benefit from faster, more accurate invoice processing.

Start early, stay informed and treat e-invoicing as more than a legal requirement. With the right preparation, your finance team can turn compliance into a strategic advantage, improving efficiency, accuracy and cash flow visibility across the business.
