The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
We have been using R+L LTL Freight Quotes App for quite some time now. The App seems to expensive for what it is. The quotes are not matching the bills from R&L. We are loosing money on almost every shipping transaction.
The app retrieves shipping rates directly from R+L. As long as the shipping parameters entered into the app match what is used when processing the shipment on R+L's website, the rates will match to the penny.
