ACTION FLOW, St. Louis, offers the ActionFlow® software for countertop-shop workflow and management.
The software is designed around the concept of a process automation engine - it logically moves through a job from quote to installation, and prompts users for the exact information at the exact time it's needed.
It also keeps track of inventory, provides work schedules and holds all data safely in the Microsoft Azure cloud.
ActionFlow keeps track of what's available as far as slabs (and remnants) and can assign pricing -- not only for standard square-feet measurements, but also for custom requirements.
