Digitalisation does not stop at the workshop door. While digital job intake and online appointment booking are already part of everyday life in many automotive businesses, another topic is moving inexorably into focus: the electronic invoice (e-invoice). When working with public-sector clients in particular, it is no longer merely an option but a legal obligation. This article explains what automotive businesses need to know about e-invoicing and how to make the switch smoothly using CATAMA software.
What is an e-invoice, and why is it more than just a PDF?
Many people picture an electronic invoice as a PDF file sent by email. That is only half the truth. A genuine e-invoice is an invoice that is issued, transmitted and received in a structured electronic format which enables it to be processed automatically and electronically.
Unlike a simple PDF, which is often unsuitable for machine reading, an e-invoice contains the invoice data (such as invoice number, amounts and line items) in a clearly defined, computer-readable structure.
The advantages are obvious:
- Efficiency: Automated processing saves time and reduces manual effort.
- Fewer errors: No more typos when transferring data.
- Faster payment: Invoice processing at the recipient’s end is accelerated.
- Lower costs: Reduced spending on printing, paper and postage.
- Legal certainty: Compliance with the statutory requirements for public-sector contracts.
XRechnung vs. ZUGFeRD: two standards for Germany
Two central formats have become established for implementing e-invoicing in Germany:
XRechnung: This is the national standard for electronic invoicing to public-sector clients in Germany. It is a pure XML data format. An XRechnung cannot be read directly by the human eye; it is designed exclusively for machine processing. So if you repair a vehicle belonging to the local police force or the municipal works department, the authority will very probably require an XRechnung.
ZUGFeRD (Zentraler User Guide des Forums elektronische Rechnung Deutschland): This format takes a hybrid approach. It consists of a PDF file (for human readability) and an embedded XML file (for machine processing). That makes ZUGFeRD flexible to use, in both the B2B (business-to-business) and the B2G (business-to-government) sector.
The challenge for automotive businesses
Creating an XRechnung manually is practically impossible. The XML structure is complex and requires specific details such as the routing ID (Leitweg-ID) of the public-sector client. This ID ensures that the invoice is forwarded digitally to the right place within the administration.
For an automotive business this means that simple invoicing software or a word processor is no longer sufficient for invoicing municipalities or state and federal authorities. It takes a software solution that masters these formats.
The solution: creating e-invoices easily with the right industry software
This is where our modern workshop management system CATAMA comes in. Software specialised in the automotive sector such as CATAMA can map the entire process from job creation through to invoicing and generate the required e-invoice formats at the push of a button.
CATAMA was developed specifically for the needs of automotive businesses and integrates e-invoicing seamlessly into familiar workflows.
With CATAMA, automotive businesses can generate their invoices – which already contain all the relevant data from the workshop job, such as labour values, spare parts and customer details – in both ZUGFeRD and pure XRechnung format with just a few clicks. The process could hardly be simpler:
- Process the job as usual: All services and parts are recorded in the system.
- Create the invoice: The software generates a standard invoice from the job.
- Choose the e-invoice format: When finalising the invoice, the user selects whether an XRechnung or a ZUGFeRD invoice should be created.
- Enter the routing ID: The dedicated field is filled with the routing ID supplied by the public-sector client.
- Generate and send: The software creates the correct file, which can then be uploaded via the designated public administration portals or sent by email.
Because it is integrated into the workshop software, all mandatory details are taken over correctly from the system, which minimises the risk of errors and ensures compliance.
Conclusion
For automotive businesses that work with the public sector, the e-invoice is an unavoidable necessity. What looks like a complex hurdle at first can be mastered simply and efficiently with the right technological support. Rather than relying on isolated tools, it is worth using integrated industry software such as CATAMA, which maps the entire process and makes creating XRechnung and ZUGFeRD invoices child’s play. That way you are not only on the safe side legally, but also optimise your internal processes and prepare your business for a digital future.
