E-Invoicing: Obligation, Opportunity, and Reality in Everyday Business

E-invoicing is no longer a topic for the future. It is already a reality. With legal requirements in Germany and across other EU countries, companies are now facing a key question: how do we implement this in a meaningful way?

Many initially see it as just another compliance requirement. More effort, new processes, additional costs. That perspective is understandable, but it is too limited.

What is really changing

With the introduction of e-invoicing, not only the invoice format changes, but the entire process behind it.

Invoices are no longer simply sent as PDFs via email. They must be structured, for example in formats such as XRechnung or ZUGFeRD. This means:

• Data must be correct and complete
• Processes must be properly structured
• Systems must be able to communicate with each other

Especially in companies with complex and historically grown system landscapes, this becomes the real challenge.

Typical starting point

In many companies, the current situation looks like this:

• Invoices originate from different sources such as SD, FI, or manual postings
• Forms have evolved over time, including Smartforms and custom developments
• Sending is done via email, partly automated and partly manual

This works, but it is not scalable.

As soon as e-invoicing formats become mandatory, simply sending PDFs is no longer sufficient.

The common misconception

A frequent mistake is to view the topic purely from a technical perspective:

“We need a tool that generates XML.”

That is too simplistic.

In reality, it involves:

• Format logic, meaning who receives which format
• Transmission channels such as email, Peppol, or platforms
• Archiving
• Monitoring and traceability

This is where the difference between a basic solution and a sustainable long-term solution becomes clear.

Portal vs. integration: what makes sense

There are generally two approaches:

1. Simple solution, portal-based

Suitable for a quick start:

• Upload PDF
• Automatic conversion into e-invoice format
• Sending and receiving via a portal

Fast to implement with minimal IT effort.

2. Integrated solution, for example ERP or SAP

For companies with higher volumes or more complex processes:

• Direct integration into ERP systems
• Automated processing from SD and FI
• Control via customizing
• Connection to networks such as Peppol

Much more efficient and sustainable in the long run.

What modern solutions look like today

Modern e-invoicing platforms now go a step further.

For example, the Melasoft solution Docnova enables:

• Creation, sending, and receiving of e-invoices within one system
• Support for all common formats such as XRechnung, ZUGFeRD, and UBL
• Transmission via email or Peppol
• Processing of PDFs, XML, and even scanned documents using OCR

In addition, such platforms can be directly integrated into existing systems such as SAP, Microsoft Dynamics, or other ERP systems, allowing full automation of invoice processes.

An important point:

Companies no longer need to choose between a portal and an integration.
Many modern solutions combine both.

One key advantage: everything in one system

A common pain point in companies is fragmentation:

• One tool for Germany
• Another for France
• Yet another for archiving

This quickly leads to:

• Media breaks
• Increased effort
• Lack of transparency

Modern platforms therefore consolidate:

• All formats
• All countries
• All processes

Into a single system.

This significantly reduces complexity.

Why this topic matters now

Many companies are currently trying to achieve minimal compliance. This is understandable, but often only makes sense in the short term.

Because:

• More countries are introducing mandatory e-invoicing
• Reporting requirements are increasing
• Processes are becoming more automated

Those who set things up properly now can avoid duplicate implementations later.

Scalability as a key factor

An often underestimated question is:

Will the solution still work in two or three years?

For example:

• Today Germany
• Tomorrow France
• Then additional EU countries

If a separate solution is introduced for each country, a fragmented system landscape quickly emerges.

That is why many companies are increasingly choosing:

• One platform
• One provider
• One unified architecture

Conclusion

E-invoicing is more than just a new format. It is the entry point into a more automated and standardized financial world.

Companies that approach the topic strategically benefit from:

• Fewer manual processes
• Higher data quality
• Better traceability
• Lower long-term costs

The question is no longer whether to address it, but how.

And this is exactly where it pays off to make the right decisions early.
