Duplicate Payment Risk Analyzer Online Free
Detect exact and probable duplicate supplier payments before reconciliation or recovery.
Duplicate Payment Risk Analysis
Detect exact and probable duplicate payments using supplier, invoice, amount and payment-date evidence. Processing stays in your browser.
How the analysis works
Transparent AP control logic
Supplier, normalised invoice number and paid amount are compared for exact duplicates. Missing payment references are separately treated as review signals.
This is decision support. Confirm ERP status, bank evidence, disputes, approvals and authorised payment policy before taking action.
What you will get
An actionable AP review
✓ Duplicate risk score
✓ Exact duplicate candidates
✓ Missing-reference review
✓ Payment traceability
✓ Recovery/hold recommendation
✓ XLSX exception report

Business context
The business problem this tool helps solve
Duplicate-payment analysis compares supplier, invoice, amount and payment evidence to identify records needing recovery review.
What can happen when the issue is ignored
- • Same invoice paid twice
- • Formatting differences hide duplicate references
- • Missing bank reference weakens reconciliation
Who should use this tool?
This guidance is designed for people who need to use duplicate payment risk analyzer results in a real approval, planning or operational workflow.
Procurement teams
Confirm invoice values against purchase orders and agreed prices.
Finance controllers

Input guide
Prepare the inputs before calculation
| Column | Purpose | Example |
|---|---|---|
| Supplier * | Paid vendor. | Northstar Packaging |
| Invoice Number * | Supplier invoice reference. | INV-4812 |
| Paid Amount * | Settled payment value. | 48200 |
Mapping note: Use consistent dates, currencies, units and definitions. A correct calculation based on inconsistent inputs can still lead to a poor decision.
