Customer basis is fine if you have a staff to deal with it all also years ago there weren't the hundred of choices there are today the demand is there for fast results and prompt delivery as the business model for many manufactures is on demand as needed ,large assembly of auto has no desire to stock the thousands of part needed for more time than is immediate! Go ahead continue to make errors and pay us to bail you out!
I did this back in the day before cell phones.....it was with beepers/pagers. Had no office staff either, except for my Mom (rip) who'd answer the home phone!
Expedite is not just about the JIT manufacturing. *The following are some of my examples of actual freight i delivered! It's that piece of freight the plane won't touch! 800lbs frozen KFC for a grand opening. The coal mine who dropped big money for that small box of tractor parts to keep that bulldozer operating! The skid of empty aluminum cans to rural South Carolina because again no proximity to a major airport.
You'd be surprised when shippers (now remember we're talking this was when Expedite was in its infancy stages) thought they're were shipping critical freight via air, it was actually trucked!
