E-invoicing obligation 2025: The 5 biggest mistakes – and how to avoid them

E-invoicing has been a reality for many companies since 2025. While some see the changeover as a bureaucratic hurdle, there is a far greater vision behind this obligation: the digitalization and automation of business processes.

But what does this mean in concrete terms for companies? In practice, we see time and again that invoices get lost in unstructured processes, end up in email inboxes without a clear assignment or have to be laboriously collected for accounting purposes. The introduction of e-invoicing is intended to prevent precisely this. Less paper, fewer errors, more transparency – and ultimately a more efficient way of managing documents.

Despite these advantages, there are many misunderstandings surrounding e-invoicing. It’s high time to clear up the biggest misconceptions and show how companies with a document management system (DMS) such as GREYHOUND as part of the JTL Group not only meet the legal requirements, but also optimize their processes in the long term.

Misconception #1
"The obligation only applies to large companies."

Fact: The e-invoicing obligation applies to all companies in the B2B sector.

• From 2025: All companies must be able to receive e-invoices.
• From 2025: Companies with a turnover of over €800,000 must issue invoices in a structured format (e.g. XRechnung or ZUGFeRD).

This means that even small companies should start thinking about the changeover now – because if you jump on the bandwagon later, you risk unnecessary stress and additional costs.

Misconception #2
"A PDF is enough."

Fact: An e-bill is not just a digital invoice.

• A PDF alone does not fulfill the legal requirements.
• An e-invoice must be in a machine-readable format such as XRechnung or ZUGFeRD.

What this means: Anyone who continues to only send PDFs risks invoices being deemed invalid and tax deductions not being recognized.

Misconception #3
"The changeover is complicated and expensive."

Fact: With the right tools, switching to e-billing is not only easy, but also saves time and money in the long term.

• A DMS such as GREYHOUND can automatically receive, assign and process invoices.
• Manual work is reduced, errors are avoided and approval processes are accelerated.

What this means: The one-off implementation of a DMS quickly pays for itself. Companies that rely on digital processes benefit from more efficient workflows and less administrative effort.

Misconception #4
"We still have enough time."

Fact: The receipt of e-invoices has been mandatory since 2025

• Although there are transitional periods for shipping, those who prepare now will save themselves a lot of stress later.
• Companies that change over too late risk delays and chaos in their accounting.

What this means: the sooner you deal with the changeover, the better. With a DMS like GREYHOUND, you can not only meet the legal requirements, but also modernize your entire accounting processes at the same time.

Misconception #5
"A DMS is only worthwhile for large companies."

Fact: Every company benefits from a DMS – whether small or medium-sized.

• Invoices, contracts and other documents are stored centrally and can be retrieved at any time.
• Manual approval processes are no longer necessary, documents are assigned automatically.
• Archiving is GoBD-compliant and audit-proof.

What this means: With the introduction of mandatory e-invoicing at the latest, professional document management will become indispensable. Those who digitize their processes now will work more efficiently and avoid costly errors.

E-billing as an opportunity - digitalization as a competitive advantage

The introduction of e-billing is far more than just a legal obligation. It offers companies the opportunity to modernize their entire document management and thus create a real competitive advantage.

A DMS like GREYHOUND helps to automatically receive, manage and legally archive invoices – and saves time, costs and nerves at the same time. But that’s just the beginning:

• Transparency & control: Invoices can be called up at any time and can be processed automatically.
• Fewer errors & faster work: Automatic assignment of documents reduces manual work and prevents bottlenecks.
• Legal certainty: All invoices are archived in compliance with GoBD and are audit-proof.
• Better collaboration between teams: Processes can be optimized through central access to documents.

Our conclusion: act now instead of regretting later!

The e-invoicing obligation is coming – and it is not just a bureaucratic monster, but a real opportunity to optimize processes. Companies that prepare early will be ahead of the game and benefit from more efficient processes.

GREYHOUND not only provides you with a legally compliant solution, but also takes your entire document management to the next level.
