GOpus® E-Invoice: Add-On for creating outgoing e-invoices with SAP

Create e-invoice in SAP

With our SAP add-on GOpus® E-Invoice you get the solution for simple and secure integration of electronic invoicing in SAP® ERP and SAP® S4HANA.

In doing so, we use the message control of the respective SAP modules and components.

We fill the e-invoice data structures with invoice data of the SAP invoice to be sent and then use a transformation to finally create the electronic invoice in ZUGFeRD format. In addition, we serve all national and international e-invoice formats.
