Duplicate payment detection
Find duplicate payments in your AP data — with the evidence to prove it
SpanFin reviews your payment exports and flags payments that look like they were made twice, while ignoring legitimate recurring charges like rent and subscriptions.
What SpanFin checks
- Same vendor, same amount, same currency paid twice within 30 days
- Same amount paid to two different vendors within 7 days — a sign of a duplicate vendor record
- Recurring schedules detected automatically, so monthly payments aren't flagged as duplicates
- Refunds with no matching credit note from the vendor
- Payments that exceed the invoice they reference
- A materiality floor so tiny amounts don't bury real issues
How it works
- Step 1
Upload a CSV
Export payments (and optionally invoices) from your ERP or accounting system. Files are scanned for safety before anything is read.
- Step 2
Review findings
Each finding shows the exact payments involved, why it was flagged, severity and potential exposure.
- Step 3
Resolve and export
Mark findings confirmed or dismissed, and export an audit trail for your controller or auditors.
Common questions
Why do duplicate payments happen?
Common causes are the same invoice entered twice, a vendor set up under two records, or a resent invoice with a slightly different number.
Will it flag my monthly subscriptions?
No. SpanFin detects recurring payment schedules and suppresses those pairs, showing you why it did so.
Do I need to connect my ERP?
No. SpanFin works from CSV exports, so you can start without IT involvement.
Is my file stored safely?
Files are checked for malware and stored privately in your workspace as unchangeable originals.
