*In a company, there are those who stand on the main stage and those who never step into the light.
Sales creates the numbers, planning speaks of dreams, and management talks of the future.
And the accounting department is the one that translates all of that into the cold reality of "numbers."
"I cannot approve that expense." "This is over budget." "These figures don't match last month's."
Today, once again, a voice that sours someone's mood echoes across the quiet floor.*
