title: "How to catch duplicate and suspicious invoices with AI"
description: "Start with the invoices waiting for payment and a year of paid history, and agree what should be checked: the same invoice paid twice under a slightly different number or amount, bank details that changed recently, suppliers not on the approved list, prices well above the agreed rate and invoices without a matching order or receipt. AI compares each new invoice with the history, supplier records and orders, and holds anything that matches a check, with the reason and the records it compared. A person in accounts payable reviews every hold, confirms any bank detail change through a known contact before payment, and decides whether to pay, query or reject."

# How can a finance team use AI to stop duplicate payments and spot invoices that look wrong before they are paid?
Start with the invoices waiting for payment and a year of paid history, and agree what should be checked: the same invoice paid twice under a slightly different number or amount, bank details that changed recently, suppliers not on the approved list, prices well above the agreed rate and invoices without a matching order or receipt. AI compares each new invoice with the history, supplier records and orders, and holds anything that matches a check, with the reason and the records it compared. A person in accounts payable reviews every hold, confirms any bank detail change through a known contact before payment, and decides whether to pay, query or reject.
## What this means in practice
- Start with pending invoices and a year of paid history.
- Agree the checks, such as near-duplicates, changed bank details and unknown suppliers.
- Compare each invoice with history, supplier records and orders.
- Hold matches with the reason and the records compared.
- Confirm bank changes through a known contact and let a person decide.
## How Lid Vizion approaches it
We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.
