Q: What is ERS?

A: ERS (Evaluated Receipt Settlement), is often referred to as Self-Billing and is an automated invoicing process where invoices are issued by ExxonMobil on behalf of the Supplier. An invoice is created automatically in SAP as soon as the Goods Receipt / Service Acceptance is booked.  A copy is sent to the Supplier (if required) with payment done per agreed payment terms.

ERS invoices are valid tax document which comply with all local tax requirements and contain all data necessary for efficient allocation on Vendor's side.

ERS is solely related to invoicing and does not affect any preceding part of the PtP process (e.g. SES creation) and is not associated with 3rd party access.

A: You can submit credit invoices the same way you submit other invoices. Please ensure the credit includes a negative balance and references the original debit and purchase order number.
