Free LTL invoice audit tool
Upload your carrier invoice — and your Bill of Lading — and we’ll break it down line by line and flag what changed: added weight, a reclass, or an extra accessorial. Takes about a minute; just add your email and we’ll show your results on screen.
How your files are handled: to produce this breakdown, the files you upload are sent to Anthropic’s Claude AI service for analysis. GetLTLRates does not save the files. Your name, email and the file name are sent to Armstrong’s team so they can follow up. Privacy details

Freight class drives your rate — and getting it wrong is the most common reason a quote and an invoice disagree. Enter your pallet for an estimated density-based freight class. Some commodities have NMFC-specific classifications — we can verify the final class before booking.
- ✓Cubic feet, density and estimated NMFC class in real time
- ✓The same brackets carriers use to reweigh on the dock
- ✓No email required — use it as often as you like
