The initial situation
Electronic invoicing in the B2B sector will gradually become mandatory in Germany from 2025 until 2028.
Prepare for this changeover in good time to benefit from advantages such as cost savings and automated processes. E-billing contributes to better transparency and traceability of business transactions.
Do you want to prevent the IBAN on your invoices from being forged in the event of a cybercrime attack?
Do you want to give your customer the certainty that the electronic invoice actually comes from you?
Would you like to automatically validate the signatures on electronic incoming invoices and handle the internal approval process seamlessly and in a traceable manner?
High savings potential
The type of electronic dispatch process for outgoing invoices to your customers plays a key role. It is common practice for many companies to send electronic invoices to customers by email, often still as PDF files, in structured form in XML format or as hybrid PDF formats (XRechnung, ZUGFeRD, etc.).
Traceable security and reduced cybercrime risk
Unfortunately, it often happens that electronic invoices are manipulated by third parties, a false account number is often quoted and the invoice amount ends up in someone else's account and is therefore lost.
However, it is possible to sign the invoice automatically using an official company certificate or seal and then send it to the customer by email. This gives your customer the assurance that the invoice actually comes from you, has not been tampered with and that the money is going to the correct account.
The r>it signature services have been used by a large number of customers for 20 years and have proven themselves in business practice.
Solution
Electronically sign hybrid PDF or XML invoices from SAP
With the e-Sign 4 SAP add-on, the signature process can be seamlessly and easily integrated into your existing SAP ERP or S/4HANA invoicing process. Once an invoice has been generated in SAP (PDF, XML or both), the file is automatically transferred via the e-Sign 4 SAP add-on to the relevant e-Sign 4 service for processing. Software certificates or seals of your choice, issued to the company and/or an individual by an authorised certification service provider, are used for the signature or validation process.

Advanced certificates or digital seals are recommended for signing invoices. However, qualified certificates in the form of digital seals or a mobile remote signature may also be used. Electronic time stamps are also frequently added as an option.
Once the signature or validation process is complete, the invoice is automatically linked to the original document in SAP® ERP or S/4HANA and stored in the existing archive.
The entire process can be monitored either by the relevant department or by IT directly within SAP®. Every single step in the process can be traced in full.
Validate electronically signed PDF or XML invoices
If you receive electronically signed invoices from your supplier in PDF or XML format, you are obliged to validate the electronic signature (to verify the authenticity and integrity of the document). To save you from having to carry out this task manually, the e-Sign 4 Validation Service is available for automated validation. A validation report confirms that the check has been carried out and is transferred to the SAP system together with the electronic incoming invoice for further processing.
