Route accounting describes the work of running a delivery business route by route: planning what each truck carries, recording what was delivered, refused or returned at each stop, and settling each route's paperwork and money at the end of the day. In direct-store-delivery businesses it often includes drivers selling and collecting payment on the route.
For food distributors the core of it is making sure the invoice matches what actually arrived. Partial deliveries, refused cases and returns at the door all change what the customer owes.
APFoodz plans routes, records each stop with proof of delivery, and invoices what was delivered.
