Outbound, fuel in Georgia. Coming back, same state.

The state tells you where the price is; it does not tell you which exit, how many gallons the tank needs to reach it, or whether the IFTA math flips the answer. That is the per-dispatch work ValveRide Flow does automatically, with your contract rates on top of the posted price.
