/ THE SHORT ANSWER
- 01A valid invoice does not validate new bank details.
- 02Verify changes through an independent contact path.
- 03Design urgency and staff absence into the control.
/ dotSuper point of view
The most important boundary in invoice automation is between deciding that money is owed and deciding where it should be sent.
Recognize the two decisions hidden in one email
The email also says the supplier has changed banks.
Matching the invoice proves neither the sender's identity nor the new destination.
A single approval button can unintentionally collapse those separate questions.
The FBI describes business email compromise scenarios involving apparently legitimate payment requests and compromised correspondence.[
1] Our operating recommendation is to make payment-detail changes visible as a distinct case type, rather than allowing them to pass through ordinary invoice extraction.
Map the current process from mailbox to bank file.
Identify every place a person, integration, or spreadsheet can edit payment details.
The most consequential write permission may sit in a vendor import job rather than the payment screen.
Worked hypothetical: a real invoice with altered instructions
Its invoice matching system finds the correct purchase order and receipt.
A new attachment supplies replacement ACH instructions and urges payment before the supplier's month-end close.
The system creates a bank-change case and holds the destination update.
An authorized employee uses the established supplier contact route and discovers that the supplier has made no change.
The invoice remains a legitimate payable, but the requested destination is rejected.
The $42,000 amount is illustrative.
The example does not claim that a real loss was prevented or that every fraudulent request will be detected.
Its purpose is to show why invoice validity and bank-detail validity need separate outcomes.
Create a verification path outside the request
Calling a number contained in the same suspicious attachment only repeats the sender's story.
Keep a supplier contact register with a named owner and a controlled method for updates.
The FBI advises independently verifying payment requests and changes to account numbers or payment procedures.[
1] Translate that advice into a specific task: who contacts whom, what evidence is recorded, and who authorizes the master-data update afterward.
A familiar voice or video image should not be the sole basis for a consequential change.
Use the company's approved verification process and consider multiple independent checks for higher-risk cases.
Record unresolved inconsistencies instead of relying on an employee's confidence.
Separate permissions without designing an impossible process
In a very small company, different people may cover these roles only at key moments.
Document the compensating oversight and use a bank-level approval control where available.
The checklist below is an original workflow proposal.
Choose thresholds and approval arrangements with the controller and bank, considering transaction risk and staffing.
Avoid making a routine low-value invoice require the same investigation as an unexpected destination change.
Preserve the invoice and supporting approval evidence together.
IRS recordkeeping guidance emphasizes maintaining supporting records for business transactions.[
2] That establishes the value of a coherent record; it does not prescribe this particular fraud-control architecture.
| Step | Evidence to retain |
|---|---|
| Detect | Original request and changed fields |
| Verify | Independent contact route and outcome |
| Approve | Authorized second review |
| Update | Vendor-master change history |
| Release | Approved destination matched to bank instruction |
| Exception | Reason, owner, and unresolved risk |
Make exceptions visible during payment pressure
The default should be an explicit hold or approved alternative under company policy.
Do not let urgency silently grant a clerk additional permissions.
Restrict AI tools to proposing extracted values and explaining discrepancies.
A model should not learn that repeated urgency is a reason to skip verification.
Keep destination updates behind a deterministic authorization step with a record of the approving people.
If a suspicious transfer has already occurred, follow the incident process immediately.
The FBI recommends promptly contacting the financial institution and reporting business email compromise through IC3.[
1] Have those routes accessible before an incident rather than searching through old emails.
Review the controls at the point money moves
An approval in the ERP is insufficient if an exported spreadsheet can be altered afterward without detection.
During the next payment cycle, inspect a small set of legitimate recent bank changes.
Check the independent contact evidence, permission history, and final payment destination.
Use missing evidence to improve the workflow rather than declaring an undocumented verbal check successful.
Measure verified changes, unresolved exceptions, and overrides separately from invoice throughput.
Faster invoice processing is useful, but it should not obscure the destination decision.
The strongest implementation makes that decision clear even when the finance team is busy and a supplier is impatient.
