Product
Turn shipping data into an audit.
Built for finance and operations teams who want a first pass on carrier invoices without sending files to a vendor.
Surcharge breakdown
See how much of each invoice goes to fuel, residential, delivery area, handling, address correction, and other fees.
Cost anomaly detection
Flag shipments whose surcharge rate or total cost sits well above the rest of the file.
Duplicate detection
Catch rows that share the same tracking or invoice identifier and the same billed total.
Estimated review opportunity
An estimated review opportunity based on transparent heuristics — never presented as guaranteed recovery.
Exportable reports
Download an HTML audit report or a CSV of flagged transactions. Both are generated in the browser.
Private browser-based processing
Your invoice data stays in your browser. Nothing is uploaded, stored, or sent to a server.
How it works
Four steps. No account.
01
Upload
Drop a carrier or accounting CSV. Files are read with the browser File API.
02
Analyze
SurchargeCheck maps columns, totals spend, and runs the review heuristics.
03
Review
Inspect flagged shipments, filter by issue type, and open any row for detail.
04
Export
Save a local audit report or a list of flagged transactions — still without uploading.
See the product with demo data.
Load 100+ realistic sample shipments — including high-surcharge rows and duplicate-looking charges — without using a real invoice.
