The sub who lost in court
A subcontractor turned in his daily reports, finished the job, and didn't get paid. When he sued, the GC counter-sued — claiming he never submitted the reports at all. He had kept no copies. He had no proof. He lost.
Construction attorneys say the same thing over and over: "If you didn't document it, it didn't happen." Your daily log is the evidence — but only if it's yours, on your phone, with timestamps nobody can question.
