E-Invoicing in 2027: Are German Companies Really Ready?

On January 1, 2027, e-invoicing becomes mandatory for nearly every business in Germany. Companies with more than €800,000 in revenue go first; everyone else gets one more year. The clock is ticking. The priority now is to make the most of the months that are left and to leave enough runway to test the new processes properly.

Not as new as it sounds

E-invoicing itself isn’t new. Since November 2020, businesses invoicing Germany’s federal government have, with few exceptions, had to do so electronically. That requirement stems from an EU directive on public procurement, which aimed to make sure public agencies could receive and process electronic invoices using common standards.

What’s new is the sheer scale at which it’s now hitting the B2B world. Since early 2025, every business in Germany has had to be able to receive e-invoices, and real-world adoption is gradually catching up. And that’s just the start: beginning in July 2030, the EU’s “VAT in the Digital Age” (ViDA) package will add digital reporting requirements for cross-border transactions.

In other words, things are only just picking up speed. Starting in 2027, companies will be dealing with far more e-invoices than they are today. Very few are genuinely ready for that, and that’s exactly what our research shows.

A gap between perception and reality

In April 2026, we surveyed 300 German companies about e-invoicing. Many think they’re well on track. Look more closely, though, and it’s clear that a lot of them are badly underestimating how much work is involved.

Three in four respondents (75 percent) described their invoicing as digital, but only 6 percent said they already met every e-invoicing requirement. So while most companies have the technical basics in place, they’re still working toward full compliance one step at a time.

Even so, almost nine in ten were confident they’d hit the deadlines with no trouble, even though more than half (56 percent) had yet to adopt an invoice format that actually meets the legal requirements.

What the numbers mean for leadership teams

These findings raise some practical questions for any company working through its own rollout. The questions in the table are my own takeaways from the data. They point to where leaders should be looking more closely.

Now is the time to walk through both everyday invoicing scenarios and the edge cases: Can you create, send, receive, and archive structured invoices correctly? What happens when the data is wrong or an invoice gets rejected? A realistic plan doesn’t stop at go-live; it builds in time for test runs, fine-tuning, and proper team training so everyone knows what to do, whatever the scenario.

Why it pays to move early

Over the next few months, many German companies will go through a significant technology shift. Some invoices still go out on paper or as plain PDFs, but the structured e-invoice is fast becoming the standard way to stay compliant.

From what I’ve seen, larger companies are further along. Many small and midsize businesses still don’t have the right solution in place, but that’s a very solvable problem. My advice: use the next few weeks to get the ball rolling. If you start working through it step by step now, you’ll be in good shape to meet every deadline before December.

France is a good example of why waiting is risky. The country began phasing in mandatory e-invoicing on September 1, 2026. According to the French Ministry of Finance, only 66 percent of companies in the reform’s core target group had chosen an invoicing platform by launch day, which means roughly a third were still undecided. And picking a platform is only step one. The sooner it’s up and running, the sooner the benefits start showing up in day-to-day operations.

Companies that have already made the switch are seeing real benefits. The Quadient survey bears this out: nearly half (48 percent) report lower costs, 34 percent have seen their days sales outstanding (DSO) come down, and one in three say they’re making fewer processing errors.

Look beyond the deadline

If you’re overhauling your invoicing processes now, don’t just focus on hitting the deadline. Think about how things will run day to day. E-invoices reach customers faster. Add AI to your accounts receivable process, and the cash can land in your account sooner, too. So it’s worth exploring what AI could do for you while you’re making the switch.

It’s just as important to keep an eye on what’s coming next, such as a German reporting system or further EU requirements. Whatever solution you choose should be able to grow with you.

My expectation is that most companies with annual revenue above €800,000 will have at least a stopgap solution in place by year-end. That will let them send and receive structured invoices, though often with some extra manual work. To get the full value out of e-invoicing, the logical next step is full automation.

The key is to keep questioning your processes after go-live. How many invoices go through without anyone touching them? Where are questions coming up? Which errors keep happening? As e-invoice volumes grow, you may uncover weak spots that never showed up in testing.

So the work doesn’t end on New Year’s Day. I expect there will still be plenty of cleanup to do in the first half of 2027.
