Who this guide helps
Businesses receiving new payment instructions
The short answer
Pause and verify through a previously established contact channel. A message sent from a familiar address is not sufficient evidence that a new account belongs to the supplier.
Practical workflow
Keep the change request and invoice, then contact the known supplier representative using a number obtained independently of the suspicious message. Ask why details changed and who authorized the update. Compare the recipient's legal name with the contracting entity. Route the change through your own approval process, with a second reviewer where feasible.
What a useful handoff looks like
Save a verification record that identifies the channel, person, date and unresolved differences without publishing financial details. Only an authorized payment decision-maker should release funds. If fraud is suspected or money was sent, contact the bank promptly through its official channel.
Mistakes to avoid
Do not reply to the same message to perform an independent check. Avoid relying on a screenshot of banking details or pressure that a shipment will be lost unless funds move immediately.
Working example: fields to record
| Field | Illustrative entry — replace with your own facts |
|---|---|
| Known channel | Previously verified supplier office |
| Recipient mismatch | Different legal entity requiring explanation |
| Release decision | Authorized reviewer confirmation pending |
Add your own entries; the example is illustrative. Keep sensitive information private.
