The rise of e-invoicing across Europe is not just a technological trend, it’s a strategic response to a long-standing financial issue faced by tax authorities: the VAT gap. This gap represents the difference between expected VAT revenues and what governments actually collect, often due to fraud, tax evasion, errors and insolvencies. According to the latest official EU report, the VAT gap in 2022 amounted to €89 billion in lost revenue. To put this into perspective, that’s more than the entire GDP of Luxembourg, which is around €82 billion.

Governments are now accelerating the adoption of e-invoicing as a proven method to combat VAT fraud and improve compliance. Since e-invoicing enables real-time monitoring, reduces manual errors and increases transparency, these new processes are going to reshape how businesses interact with tax authorities and manage their financial operations.

From EDI to e-Invoicing: Lessons Learned

While e-invoicing may seem revolutionary, the concept of exchanging documents electronically isn’t new. Electronic Data Interchange (EDI) has been around for decades. However, EDI taught us the critical lesson that simply digitizing document exchanges doesn’t guarantee internal efficiency. Many organizations still struggle with fragmented processes, a high amount of manual interventions and lack of visibility.

This is precisely why accounts payable (AP) automation solutions emerged during the EDI era and why they remain essential today. As e-invoicing mandates become the norm, AP automation is more relevant than ever.

Why AP Automation Matters

So, why should companies invest in AP automation now?

The answer mirrors the rationale behind e-invoicing mandates: money is being lost in inefficient processes, and organizations face delays, errors and missed opportunities for cost savings.

In practice, the AP process is far more complex than the theory suggests. Large manufacturers, for example, often operate across multiple countries, business units and ERP systems. Mergers, acquisitions and spin-offs add further layers of complexity. Finance teams frequently find themselves misaligned with IT departments, struggling to manage invoices from various channels and formats, particularly when each country has its own e-invoicing regulations.

Historically, AP solutions were designed to integrate with a single ERP system, reflecting a time when ERP consolidation was the norm. But today’s reality is different, as data is scattered across multiple platforms and companies need solutions that can connect to diverse systems, unify data and provide actionable insights.

A cloud-based AP automation platform can centralize invoice data, deliver real-time visibility and generate industry-standard KPIs. This empowers organizations to benchmark performance and identify bottlenecks in their processes.

Turning Compliance into a Competitive Advantage

Every new e-invoicing mandate presents a unique opportunity to revisit and modernize legacy AP processes. Rather than viewing compliance as a burden, forward-thinking companies are leveraging it to drive transformation.

The benefits are tangible:

• Cost per invoice can drop from $12–30 to as low as $3.
• Processing time can shrink from 10–15 days to just 3 days.
• Error rates can approach zero, enabling touchless invoice processing with minimal human intervention.

In addition to improving internal efficiency, AP automation can also strengthen relationships with suppliers. Faster payments and simpler onboarding processes make your company more attractive to vendors, which in turn can lead to opportunities for better discounts or more flexible terms. The technology to make AP run more smoothly is already available. With e-invoicing rules becoming more common across Europe, it’s a good moment to update these processes. It’s the most reliable way to stay compliant and make operations stronger while finding new ways to create value.
