A Florida food distributor runs its routes on a tablet application I built: drivers load in, deliver, capture signatures and close tickets on cellular tablets, with two rules the software never lets slip. No signature, no close. Nothing delivered that was not on the truck. Ten years in, it closes better than 99.99 percent of tickets first time, more than three million so far.
It is now being rebuilt as a Laravel application on AWS, keeping every rule that earned that record and adding what the old stack could not: drivers identified through the truck's telematics gateway, the odometer read from the truck at fuel time, end-of-day returns reconciled against the live truck balance, a redesigned invoice emailed the moment a ticket closes, and a nightly hand-off to the back office that the accounting side never had to change for.
