With the help of the SAP solution GOpus®eInvoice of our partner GOpus We enable companies to process electronic invoices in a wide variety of international formats easily and automatically, directly from within the SAP® system. In a second step, these e-invoices are digitally signed or encrypted.

Particularly in the context of legal requirements, such as those set out in the EU’s eIDAS Directive or (inter-)national e-invoicing regulations, the demands placed on the authenticity, integrity and confidentiality of electronic documents are increasing. The digital signature guarantees the authenticity of the invoice and verifies that it has not been altered, whilst encryption ensures a secure transmission channel and the mandatory protection of access (e.g. via a password or token-protected link) to ensure that unauthorised persons cannot access this sensitive data – particularly in the case of sensitive B2G or B2B communication channels.

e-Sign 4 and GOpus®eInvoice complement each other perfectly: they enable documents to be signed with a qualified electronic signature and offer flexible encryption options – integrated directly into SAP and without any disruption to the workflow. This means that outgoing invoices can not only be signed in accordance with standards (e.g. as an XRechnung or hybrid PDF), but also in compliance with legal requirements and transmitted securely. Invoices and other documents can likewise be sent in encrypted form directly from SAP processes.

For SAP users, this means one thing above all: less manual effort, greater security and more automation. All functions are seamlessly integrated - from invoice creation and legally compliant signatures to automated posting. The familiar SAP environment is retained, without additional system changes or external tools. This means that companies not only benefit from increased efficiency, but also fulfil future legal requirements for electronic invoice exchange effortlessly.

With this combination, we offer our business partners a complete solution for digital invoice processing in SAP - from creation and dispatch to secure archiving. Together with GOpus we are setting a new standard for secure and legally compliant e-invoicing processes in the SAP environment.
