What is a punch list, and how do you run one properly?

A punch list — snag list, if you are British — is the list of everything still unfinished, incomplete or wrong near the end of a construction job. It is the document that stands between "nearly done" and actually done, and it is where an enormous number of projects quietly fall apart.

Why the informal version fails

Most punch lists start as a walk-through and a notepad, or a text message with four photographs. That works for about a week. Then:

• Somebody says an item was fixed, and nobody can remember whether it was checked.
• An item gets fixed badly, gets re-raised, and now exists twice.
• The list lives on one person's phone and the trades never see it.
• Nobody knows how long anything has been outstanding, so nothing feels urgent.
• At final payment there is no agreed record of what is actually left.

What a good punch item contains

1. A location. Room or area. "The scratch" is not findable; "primary bath, north wall" is.
2. What is wrong, in a sentence somebody who was not there can act on.
3. A photograph. Nearly always. It removes the entire class of argument about whether the problem is real.
4. Who owns it — which trade, which company.
5. A date it was raised. So the clock is visible.
6. A status everyone uses the same way: open, in progress, ready for review, complete.
7. A decision. Approved, or sent back with a reason.

Approve or send back — do not just tick

The single most valuable habit is separating "the trade says it is done" from "the owner agrees it is done". Those are different facts and collapsing them into one tick box is how disputes start.

A trade marks an item ready for review. The owner then either approves it or sends it back with a reason and a photograph. That is it. The trail it produces answers, months later, exactly who agreed what and when.

Who should be able to change what

Give the trades access — a punch list nobody can see is a punch list nobody works from. But a trade should be able to move an item forward and add notes and photographs, not sign off their own work and not delete anything. That is not distrust; it is just the separation that makes the record worth having. Punchlist360 enforces exactly that split, and invites are free for the trades.

Finishing it

A punch list ends when every item is either approved or formally accepted as not being done. Export it, both sides keep a copy, and it becomes the reference for the final payment conversation.
