Automated Cass Duplicate Freight Invoice Detection
Every morning, WebRun opens CassPort and scans incoming invoices for duplicates based on carrier, invoice number, shipment reference, amount, and date. Any matched pair is flagged and logged to a Google Sheet so your AP team can review before payment is released.
How do I automatically detect duplicate freight invoices before payment?
WebRun scans your Cass invoice queue every morning, matching incoming invoices against recent history by carrier, invoice number, shipment reference, and amount. Suspected duplicates are logged to a Google Sheet with the match reason and dollar exposure, giving your AP team a clear review list before any payment is released.
- Duplicate invoices caught before payment rather than recovered after
- AP team reviews a targeted list instead of scanning every invoice
- Running dollar-exposure tally shows audit value at a glance

Questions, answered
Will it automatically reject or void duplicate invoices?
No. WebRun flags and logs suspected duplicates in Google Sheets for your AP team to review. No invoice is rejected or returned to a carrier without human approval.
What fields does it use to detect a duplicate?
It matches on carrier ID, invoice number, PRO or shipment reference, amount, and billing date within a configurable lookback window. You can tighten or relax the matching rules during setup.
What happens if a flagged pair turns out to be a legitimate re-bill?
Your AP team reviews each flag in the sheet and clears it. The cleared pair is noted so the same match does not re-trigger on the next run.
