Keep the supplier and payment context attached to the check.
Open a clear first-hour checklist, preserve evidence and keep unverified claims separate from confirmed loss.
The check ends with one next action. Missing evidence stays visible and never becomes proof that a payment is safe.
Pause related payments and supplier changes.
Contact the bank through its established route.
Keep messages, headers, approvals and payment records.
Follow the company’s insurer, legal and reporting process.

Keep the supplier and payment context attached to the check.
Do not verify a request through new contact details contained in that same request.
The result supports the approver; it does not replace them.
Open the full result later from the company workspace instead of rebuilding the case from email.
