The question arises, what is a punch list and why it is the most important? It is a document written late in the execution that describes task that should be corrected, fixed, or done.

Punch list is one of the final quality control tools contractors and the clients use to align expectations. By approaching each of the items on a systematic basis, the project can be formally closed with professional reckoning.
