SupplyOn supports invoicing by: 

  • Transferring data automatically from previous purchase orders to invoices (PO flip).
  • Checking the invoice data before the invoice is sent to Siemens Energy.

The invoicing process can be outlined as follows: Most of the invoice data is taken automatically from a purchase order and the available delivery schedules from the system. Only a small subset of data, for example tax information, has to be added manually.

Alternatively, the invoice data can also be exported and uploaded from your own system.

The invoice data is validated and checked for correctness. Errors are reported in order to ensure that only valid invoices are transferred to Siemens Energy. Additional process steps, such as inclusion of a digital signature, are performed if necessary.

Sending electronic invoices is much more secure than using the conventional method. SupplyOn offers a secure system, which uses the most modern methods of user authentication, encryption and, if necessary, digital signature. The documents are sent in encrypted form, to ensure that the data cannot be read by any third parties. Only authorized users can access the documents.
