Explicación

A job several times the usual size demands payroll and material money weeks before the first progress payment lands, and retention holds part of it back longer still, so the contractor can run dry mid-project on a job that is profitable on paper. Depreciation follows the asset's schedule and is unaffected by job size. Classification follows the trade the contractor is qualified in and is never upgraded automatically. And material tax is owed on every job whatever its size.
