For UL 508A panel shops and custom builders
Quote without the spreadsheet.Keep the margin you quoted.
CostBook replaces your quoting spreadsheet. Drop in the BOM, and FAT, crating and wiring hours can't fall off. When a supplier raises prices, you see which sent quotes it hits.
Supplier raises prices. Every open quote is rechecked.
PS-3 now costs $3,240 more. Margin down from 22% to 17%. You see it before the PO.
No yes on a losing quote. Your customer can't accept until you re-price or OK it.
Why custom builds lose money
Quoted at 24%. Built at 14.5%. No single mistake to blame.
Quotes sit open for weeks. Copper doesn't wait. And what isn't on the drawing is easy to leave off. Most shops find out on the floor.

How it slips through
- 1.
The BOM only lists what's on the drawing. Ferrules, duct, the UL label, FAT, the crate. On a busy week, one gets left off.
- 2.
Nobody trusts the price book. Three estimators, three spreadsheets, last quarter's breaker prices in one of them.
- 3.
Margin and markup get mixed up. A 30% markup is a 23% margin. The quote goes out under target.
What you get
More quotes out. More margin kept.
- 02.1
Drop in the BOM. Get it back priced.
From EPLAN, AutoCAD Electrical or Excel, priced from your own price book. Engineering revises it? You only check what changed.

Every quote complete, whoever writes it.
A forgotten FAT doesn't trim the margin. It takes all of it. Set what every quote must carry, and nothing goes out until it's priced or waived with a reason.

Catch a price rise before the PO does.
Your distributor raises prices. You see which open quotes lost margin, and by how much, while there's still time to re-quote.

Why CostBook exists
Built for one shop that kept leaving things off the quote.
It started with a family business that builds IC test boards. Every quote was parts plus hours, section by section, in a spreadsheet. More than once, a material nobody priced turned a good job into a near loss. Nobody made a big mistake. Something just wasn't on the list.
I built CostBook so that couldn't happen to them again. Then I shaped it for every shop that quotes one-off builds the same way.
