🔹 Additional shipping process automation:
If you want PDFMAILER to automatically recognize and process all shipping parameters (such as shipping method, recipient data, document type, XML generation, etc.), our printing technology needs one-time integration with the forms or templates.

Frequently asked questions about e-invoicing for businesses

What is an e-invoice?

E-invoices, or electronic invoices, are digital documents that replace the traditional paper invoice. They are created in a structured electronic format (XML) that is machine-readable and allows for automated processing. ZUGFeRD and XRechnung are common formats in Germany.

Why is e-invoicing mandatory beginning in 2025?

As of January 1, 2025, all B2B companies are legally obligated to receive electronic invoices. Starting on this date, all companies must accept electronically invoices (ZUGFeRD and XRechnung). Starting in 2027, sending electronic invoices will also become mandatory.

The introduction of e-invoicing lays the foundation for a future reporting system that will require companies to report their assessable and taxable B2B sales electronically to the tax authorities. This system is intended to combat VAT fraud and enable more efficient tax administration.

Digitalization associated with e-invoicing promotes efficiency, reduces errors, shortens processing times and supports environmental protection through reduced paper consumption.

What are the consequences if I don’t use e-invoicing from 2025 onwards?

Companies that fail to comply with legal requirements for e-invoicing may face various disadvantages. These include delays in invoice processing, fines, and negative economic impact, such as strained relationships with business partners.

Beginning in 2025, it will no longer be possible to opt out of receiving e-invoices, meaning that companies that don’t adapt risk jeopardizing their cooperation with suppliers and customers, as they may not accept noncompliant invoice formats.

How can I create and send e-invoices?

E-invoices can be created and sent via ERP systems using integrated e-invoicing software such as PDFMAILER. PDFMAILER supports all required e-invoice formats (ZUGFeRD and X-Invoice) and simplifies data collection and delivery.

If invoices are created as office documents, PDFMAILER supports this by using its included AI.

Will I still be able to create invoices in Word or Excel after 2025?

Yes, you can still create invoices in Word or Excel after 2025. However, these documents must be converted into a legally accepted e-invoice format such as ZUGFeRD or XRechnung to meet the new requirements. Simply creating an invoice in Word or Excel doesn’t meet the legal requirements for electronic invoicing.

Conversion to a compliant format can be achieved using specialized software solutions. Tools like PDFMAILER allow you to convert documents directly from Word or Excel into accepted e-invoice formats and automatically extract and process relevant data. These solutions not only ensure compliance with legal regulations but also optimize the efficiency of invoice processing through automation.

Who must comply with the e-invoicing requirement and what deadlines must be observed?

As of 1 January 2025, all B2B companies in Germany must be able to receive electronic invoices. This regulation applies to all companies, regardless of their size.

Starting 1 January 2027, B2B companies in Germany will also be required to send electronic invoices. However, there are specific transitional periods and exceptions that apply to smaller companies, particularly those with annual revenues of less than €800,000.

For these smaller businesses, the obligation to issue structured e-invoices exclusively will not become binding until 1 January 2028. Until then, they may continue to issue paper invoices or unstructured electronic invoices, provided the recipient consents. This provision gives smaller businesses additional time to adapt their systems and prepare for the full transition.

It is important that all companies, regardless of size, familiarize themselves with the requirements and deadlines early on to ensure a smooth transition.

How do I prepare my company for e-invoicing?

Preparing your business for e-invoicing requires careful planning and implementation. Here’s a simple checklist to help you navigate the transition:

  • Implement the solution:
    You can implement the e-invoicing solution in your company without setting up a major IT project. Leverage the software provider’s support and resources to ensure seamless integration and deployment.

By following these steps, you’ll ensure that your company is prepared for the introduction of e-invoicing, uses the technical solutions efficiently, and complies with legal requirements without any issues.

What are the advantages of switching to e-invoicing?

Switching to e-invoicing offers numerous benefits for businesses of all sizes. Here is a detailed description of the key advantages:

Cost savings:

Reduction of printing and shipping costs: By avoiding physical invoices, companies save significantly on paper, printing and postage.
Efficient invoice processing: Automating the invoice process reduces manual intervention, significantly reducing processing time and associated costs.

Time savings:

Faster invoice processing: E-invoices can be submitted and processed immediately, accelerating payment cycles.

Automated workflows:

Many steps that are performed manually with paper invoices, such as logging, approval, and archiving, can be automated.
Reduced errors: Manual interventions are a common source of errors in invoicing. Automated systems minimize this risk by importing and processing data directly from the ERP system.

Better compliance:

Compliance with new regulatory requirements is simplified because modern e-invoicing systems can be updated and adapted to legal changes.

Traceability and transparency:

Digital invoices offer improved monitoring and auditing capabilities, increasing transparency and supporting compliance requirements.

Environmental friendliness:

Reducing paper consumption: Switching to e-invoicing contributes to reducing paper consumption, which not only saves costs but also protects the environment.

Future security:

Flexibility and scalability: Digital invoicing systems are easily scalable and can grow along with a company. New features and technologies can be integrated more easily.

These comprehensive benefits demonstrate how switching to e-invoicing not only fulfills a legal requirement but also represents a strategic investment in the efficiency and future viability of your business.

What are the key dates and deadlines for the introduction of e-invoicing?

The introduction of e-invoicing in Germany is linked to important key dates and deadlines that companies must observe to comply with legal requirements:

Beginning 1 January 2025

Every company must be able to receive, process, and archive e-invoices. The requirement to receive e-invoices applies to domestic B2B sales.

31 December 2026

End of the transitional arrangement for issuing and sending paper or unstructured PDF invoices for companies with annual revenues of more than €800,000.

Beginning 1 January 2027

Mandatory e-invoicing for B2B transactions. Companies with annual revenues of less than €800,000 may still send paper or unstructured PDF invoices.

31 December 2027

End of the transitional arrangement for issuing and sending paper or unstructured PDF invoices for all companies, organizations, associations, etc. in B2B, even with annual revenues of less than €800,000.

Beginning 1 January 2028

Obligation to comply with all e-invoicing requirements for all companies, organizations, associations, etc. The sending of paper and unstructured PDF invoices is no longer permitted.

Preparatory measures:

Companies should begin updating their systems and adapting their processes now to facilitate the transition. This includes implementing or updating ERP systems, training employees, and testing the new processes to ensure they meet the new requirements.

These deadlines and dates are crucial so that companies can take the necessary measures in a timely manner to comply with legal requirements and benefit from the advantages of digital invoicing.

How is data correctly formatted and transmitted for e-invoicing?

What are the technical requirements for the correct formatting and transmission of e-invoices? To ensure the correct formatting and transmission of e-invoices, companies must ensure that their invoice data complies with national and international standards. In Germany, for example, e-invoices must comply with the ZUGFeRD (2.0 or higher) or XRechnung standards, which ensure structured data transmission in machine-readable format. These formats facilitate automatic processing and integration into existing systems, such as ERP solutions, and ensure efficient and error-free data transmission.

PDFMAILER.SEND generates the corresponding legally required e-invoice data.

Key components for correct formatting include:
Structured data: Information such as invoice number, date, amount details and tax information must be clearly structured and labeled.

Standard-compliant tags: The use of standardized tags facilitates the automatic recognition and processing of invoice data by receiving systems.

Validation processes: Before sending, e-invoices should be validated using software tools to ensure compliance with standards and minimize errors.
