How the math works

01
Opening + delivered − closing
We convert your real tank dimensions and dipstick readings into actual volume, then work out what you should have sold.
02
Compare to declared sales
That expected figure is checked against what your POS or logbook says you actually sold.
03
Flag the risk level
Anything past normal tolerance is flagged so you know if it's worth a closer look.
