# Duplicate Invoice Detection

Find the invoices in a payment run that have already been paid — including the ones that arrived with a different number, a different date, or from a renamed supplier.

## At a glance

- Business function: Finance
- Process: Purchase To Pay
- Runs: runs on a schedule — Every Monday at 08:00, before the payment run
- Run cost: 7 credits
- Uses a knowledge base: no

## What it needs

- **Invoices pending payment** (file upload) — This week's payment run.
- **Recently paid invoices** (file upload) — What has already been settled. Without this the check cannot run.
- **Matching rules** (form)

## How it works

1. Reading the payment run
2. Reading the paid history
3. Comparing against what has been paid
4. Writing the hold list

## What it returns

- **At risk of double payment** (score)
- **Hold before the run** (written summary)
- **Hold these** (flagged exceptions)
- **Pending invoice against the paid one** (mapping table)
