How can S4FN help?
By using our e-invoicing add-on you can automate the sending and receiving of electronic invoices in Serbia directly via SAP without needing any third-party tool. All e-Invoicing processes can be managed inside SAP.
As S4FN objects are stored in their own custom namespace namely /S4FN, your existing objects in SAP remain untouched by this add-on import.
If you would rather not use an add-on and don’t want to change SAP you can use our data extractor tool with a reading user. By using RFC, invoice data can be mapped to XML and sent to the tax agency without changing SAP.
Please drop an email to contact@s4fn.com to have more details or visit our contact page.
