Expenses for retail customers who purchase products and expenses for people who provide services

[Mahmoudhafez01]

Colleagues from the SAP community

I want to propose or implement a solution on SAP S/4HANA for a retail customer we sell to, and we want to add expenses for persons related to the retail customer for services on the invoice and sales order with the definition of those who provided the service and paid for those expenses as business partners, Partner Function.

Thanks

Did you had a look at Service Billing or any form of Order related Billing with UNMW (non-valuated Materials)? 

It would be helpful if you can start designing / implementing something and then as specific questions here. 

Thanks,
