Methodology
Research question: which email characteristics deserve a second look? A new bank instruction, urgent payment pressure, a changed domain, or an unusual attachment can all change the risk of an otherwise ordinary invoice conversation.
Evidence and scope
Control boundary: a support lane can preserve the message, compare it with approved vendor details, and route it. It should not rely on the requesting message itself as independent proof or authorize a sensitive record change.
Adverse controls
Implementation: define approved verification channels, record who completed the verification, and retain stopped examples for reviewer training. CISA’s phishing guidance is a relevant external reference for recognizing suspicious requests.

FAQs
Are the planning examples benchmarks?
No. They describe a testable workflow shape and are not promises, market averages, or production targets.
What should an outsourced AP specialist own?
Repeatable preparation, documentation, status tracking, and follow-up within least-privilege access. Named finance owners retain approval and payment decisions.
When should an item be escalated?
When evidence is missing, a request changes payment details, a duplicate or fraud signal appears, or the item falls outside the written rule.
