Hidden rough-in, venting, and permit fees are the prompts that vanish under load.

The pairing
Pocket, van, desk
A walkthrough has three surfaces. The clipboard, the van seat, the desk where you explain the number. This page is the clipboard. Pair it only if you want the other two. The PDF does not wait on that decision.

Walkthrough checklist for the misses that wipe a job
The miss is not that you cannot see. It is that working memory is full while the homeowner is talking.
Gawande: checklists exist for experts under load, not for beginners who do not know the trade
How a brain actually walks a room
Why the 12th miss never makes the van notes
A free page does not need a speech about losing money. It needs to be in your pocket when load is highest. Atul Gawande's work on checklists is the whole product: experts miss steps under load, and a page beats a pep talk. This is not the full Bid Book. It is the list you can use today.
01Load, not ignorance, is what skips the permit
Checklists in Gawande's research did not insult the surgeon. They caught the step that vanishes when attention is split. A walkthrough is split attention: the room, the drawing, the person talking, the next call. The page holds the prompts your head will drop.
02A one-page list beats a file you will not open on site
Present bias favors the short thing you can use now. That is why this is free and one page. The Bid Book is there when you want the stack, the ranges, and the quote templates. This page does not wait for that decision.
03Ticking a box closes the loop
Zeigarnik showed that unfinished tasks sit in working memory. A circled blank on the list is an honest unknown you can write into the quote. An unwritten miss is an unknown that pretends to be done.
The blank at the bottom of the sheet
Those lines would make the page too long to fold
Tick rough-in, venting, permit. Then the sheet stops. There is no line for bid type, loaded labor, overhead, or profit. That is not leftover space. A fold-line page cannot hold a cost stack. Those pages live in The Plumbing Bid Book. If you also explain the quote to the homeowner, the Contractor Estimating Bundle is both books, $10.98 less than buying them apart. This sheet stays free either way. Instant digital access. Nothing ships.
On the page
Three prompts. One sheet.
01
Hidden rough-in
What you cannot see from the finished room, written as a prompt before you leave the site.
02
Venting traps
The misses that do not show up in a rushed look around the fixtures.
03
Permit fees
A line so the AHJ is not an afterthought in the van.
04
Not the full Bid Book
No bid types, no cost stack, no quote templates. Those live in The Plumbing Bid Book if you want them.
Before and after
The same week, two versions
A composite first commercial look. Not a promised win rate.
Service plumber, first commercial look
BeforeWalked the room, wrote a number in the van.
AfterChecks the page before leaving the site. Fewer 'I thought that was included' calls.
Two-person shop, remodel walkthrough
BeforeThe helper held the flashlight. Nobody held the miss list.
AfterThe folded page is on the clipboard. Circled blanks become sentences in the bid.
From the desk
“I used to walk the room and write a number in the van. The page does not make me slower on purpose. It makes the thing I skipped visible before I leave.”
