E-invoicing from 2027: are German businesses really ready?

From 1 January 2027, e-invoicing becomes mandatory for almost every business in Germany. Companies turning over more than €800,000 go first; everyone else has one more year. The clock is ticking. The priority now is to make the most of the months that remain and to leave enough time 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, intended to ensure that public bodies could receive and process electronic invoices to common standards.

What’s new is the sheer scale at which it is now reaching the B2B world. Since early 2025, every business in Germany has had to be able to receive e-invoices, and practice is gradually catching up. And that’s only the start: from 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 gathering pace. From 2027, companies will be handling far more e-invoices than they do today. Very few are genuinely ready for that, and that is exactly what our research shows.

A gap between perception and reality

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

Three in four respondents (75 per cent) described their invoicing as digital, but only 6 per cent said they already met every e-invoicing requirement. So while most have the technical groundwork in place, they are still working towards full compliance step by step.

Even so, almost nine in ten were confident of meeting the deadlines without difficulty, even though more than half (56 per cent) had yet to adopt an invoice format that actually meets the legal requirements.

What the figures mean for leadership teams

These findings raise some practical questions for any business planning its own roll-out. The questions in the table are my own takeaways from the data. They show where leaders should be looking more closely.

Now is the time to work 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 is rejected? A realistic plan doesn’t stop at go-live; it builds in time for test runs, fine-tuning and proper staff training, so everyone knows what to do whatever the scenario.

Why it pays to move early

Over the next few months, many German businesses will go through a significant technological shift. Some invoices still go out on paper or as standard PDFs, but the structured e-invoice is fast becoming the norm for staying compliant.

In my experience, larger companies are further ahead. Many SMEs still don’t have the right solution in place, but that’s a very solvable problem. My advice: use the coming weeks to get things moving. If you start working through it step by step now, you’ll be well placed to meet every deadline before December.

France shows why leaving it late is risky. The country began phasing in mandatory e-invoicing on 1 September 2026. According to the French Ministry of Finance, only 66 per cent 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 choosing a platform is only the first step. The sooner it’s up and running, the sooner the benefits are felt in day-to-day operations.

Businesses that have already made the switch are seeing real benefits. The Quadient survey bears this out: nearly half (48 per cent) report lower costs, 34 per cent have seen their debtor days fall, 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 focus solely on the deadline. Think about how things will run day to day. E-invoices reach customers faster. Bring AI into credit control, and payments 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.

I expect most companies turning over more than €800,000 a year to have at least an interim solution in place by the end of the year. That will let them send and receive structured invoices, albeit often with some extra manual work. To get the full value from e-invoicing, the logical next step is full automation.

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

So the work doesn’t stop at New Year. I suspect there will still be a fair bit of tidying up to do in the first half of 2027.
