Inventory is always a big issue due to the fact that many guys forget to bill the parts out or the stuff gets damaged from bouncing around in the truck.
We had a guy retire and I had to pick up his van and clean it out. Over his time with the company he had stashed over 30,000 in controls in his van. He purchased them and wrote the po numbers on the parts so for kicks the boss checked what the po numbers and they went back about 5 years and all issued for truck stock.
Making a long story short this guy was buying truck stock and not using it and half the parts were unusable due to damage.
After that we are not allowed any truck stock
