Use this procedure when an invoice is flagged with an unverified sender source exception. The exception indicates that the sender's email address or domain could not be verified against the supplier record or vendor contact list. You must review the exception details and take one of the available actions to resolve it.

The system evaluates the following conditions in order when an invoice email is received:

Condition A: Internal forwarding check.

The system first checks whether the email was forwarded by an internal employee.

• If the sender's email domain matches the internal email domain, no exception is created. The system adds an audit log entry: Success: Unverified Sender Source - Sender is found to be internal company employee.
• If the sender's email domain does not match the internal email domain, the system proceeds to evaluate Condition B.

Condition B: Known supplier, unknown contact.

The system evaluates this condition when the sender is not an internal employee. It applies when the supplier is successfully identified on the invoice (via OCR or purchase order match) but the sender's email address is not recognized.

• The system checks whether all of the following are true:
  • The supplier is identified as valid.
  • The sender is not found in the vendor contact list.
  • The sender's email domain matches the supplier's website domain or registered email domains in the primary supplier data or supplier contacts, OR the sender's email domain matches the email domain of other contacts in the vendor contact list.
• If a domain match is found, the exception is created. The system adds an audit log entry: Failed: Unverified Sender Source - Supplier identified and sender is found to be un-registered contact.
• If no domain match is found, the exception is created. The system adds an audit log entry: Failed: Unverified Sender Source - Supplier identified but sender's email source is unknown.
