It marks duplicates, odd amounts or changed bank details.
The payment is held from release pending review.
AP calls the vendor on a known number and decides.
The finding, the check made and the decision are recorded.
The basics
What is an AI invoice fraud detection agent?
The invoice fraud detection agent examines every invoice and vendor change against history. It looks for repeated or near-duplicate invoices, altered bank details, senders that imitate known suppliers and amounts that break a vendor's pattern. It reads invoices, vendor master data, bank change requests, payment history and email content.
Read the full explanation
Flagged items arrive with the evidence behind each flag and a note on how strong the signal is. A person verifies with the supplier, and finance decides whether payment proceeds. It can draft a verification request but does not accuse anyone, block a supplier or stop a payment. Each case is logged for security and legal review.
Where it breaks
What this agent does
Each task below is something the agent prepares, checks, drafts or routes, with a person keeping the decision.
It compares invoice numbers, amounts, dates and vendors to catch repeats and near-repeats before they are approved.
It flags changes to payment details and prepares a verification step, so a person can confirm through a known contact.
It compares sender domains, names and wording with known supplier records to flag suspicious requests.
It highlights amounts, timing or line items that differ from a supplier's normal pattern.
Each flag carries the evidence and a suggested check, ready for audit.

Under the hood
Inside the work
| Aspect | By hand | With the agent |
|---|---|---|
| Duplicate checks | Found by memory or by a chance search. | Every invoice is compared with past ones for near matches. |
| Bank detail changes | Accepted from an email with little checking. | Changes are flagged and held until a person verifies them. |
| Impersonation | A lookalike sender passes if the invoice seems normal. | Sender, domain and wording are compared with the real vendor. |
| Anomalies | Spotted only in an audit. | Unusual timing, amounts or patterns are listed as they occur. |
| Evidence | Notes are scattered across email. | Each finding stores what was seen and who checked it. |
| If | Then | Who decides |
|---|---|---|
| An invoice matches a previous one on supplier and amount | It holds it and links the earlier invoice | AP supervisor |
| Bank details differ from the vendor record | It blocks release and asks for independent verification | Treasury or AP lead |
| The sender domain does not match prior mail | It flags possible impersonation and shows the differences | Security team |
| An amount is unusual for the vendor | It marks the invoice for review with comparison points | AP clerk |
| A change request comes with urgency language | It raises the risk rank and lists the pressure cues | Treasury or AP lead |
| A vendor is verified after a flag | It records the verification and clears the hold | AP supervisor |

Hands over to
- AP reviewers receive flagged items
- Treasury receives bank change cases
- Security receives impersonation signals
Legitimate re-bill
Duplicates can be real, for instance after a corrected invoice. The reviewer decides and records why it is valid.
Vendor genuinely changes bank
The agent cannot tell a real change from a fake. A person verifies through a known channel before the record changes.
Too many flags
If reviewers see noise, the rule owner tunes the sensitivity. Tuning is logged and approved, not automatic.
Suspected active fraud
The agent keeps the evidence and holds items. Finance and security decide on reporting and recovery.
- AP reviewer
- Examines flags, contacts the vendor and decides to release or reject.
- Treasury lead
- Owns bank detail changes and the verification procedure.
- Security analyst
- Reviews impersonation signals and phishing patterns.
- Internal audit
- Samples the case log and tests that flags led to action.
