The three weights on every scale ticket: Gross (loaded truck), Tare (empty truck), Net (load only) = Gross − Tare.
## The math ``` Net weight = Gross weight − Tare weight ``` ## How tare is established - **Stored tare:** Truck weighed empty at a prior visit; tare auto-applied. - **Live tare:** Truck weighed empty at the same visit (after dumping). - **Plate tare:** Tare painted on the side of the truck (DOT plated weight). ## Common discrepancy sources - Snow, mud, or rain in the bed. - Driver in cab vs. out of cab. - Fuel level variation. - Aftermarket bed liners. ## How WeighPay handles gross/tare/net WeighPay reads the scale indicator in real time, captures both weights with the operator's choice of tare source, and prevents a ticket from closing on a negative or zero net.
