E-billing from 2025: What will change and how OS/ can help you manage the transition

An important change will come into effect on January 1, 2025: electronic invoices will become mandatory in the B2B sector.

This means that companies will have to issue and process their invoices in a structured, digital format in the future. No more paper chaos and PDFs that are unreadable by machines.

The focus is now on efficiency, transparency, and error prevention.

But what does that mean for you and your company? And how can OS/ help you make the transition?

Here are the answers.

‍

What is an e-invoice?

An electronic invoice is more than just a simple PDF file. It is created in a machine-readable, structured format—for example, in ZUGFeRD (a combination of a PDF for humans and XML for machines).

This format combines the best of both worlds: humans can read the invoice as usual, and digital systems can automatically process the data it contains.

The result: less manual input, fewer errors, and faster processes.

‍

What is changing?

First things first:

From 2025 onwards, a simple PDF invoice will no longer suffice.

Companies must be able to create and process their invoices in a structured format. This includes standards such as ZUGFeRD or XRechnung.

The advantage: These formats allow invoice data to be imported directly into ERP systems or accounting software without the need for manual entry.
