Contractors want to maintain control without making any changes. "Keep doing the same thing but expecting a different result."
Throwing the receipts in a shoebox (behind or under the seat in the truck) is the favorite way to deal with paperwork. This is "Under Managing" and frustrates everyone around them who is playing "Where's Waldo?" Job costing is nonexistent; bills are usually paid late, customers are unbilled, lost, and forgotten.
On the other hand, micromanaging every detail is an over-reaction from years of doing as little bookkeeping as possible to prepare the tax return. Knowing what to do, however, will stop you from making a big mess of it.
