The Change Order Goldmine: Where Job Margin Hides, Leaks, or Gets Signed

The truck is there, the tools are out, the customer is smiling — and the extra shutoff valve goes in free. In the sample month, 12 of 30 jobs grew past their quote: seven changes went out free at $185 of cost apiece, and the five that got billed went out at 12% margin instead of 45%. The leak: $25,836 a year, every drop of it work your crew already did.

How it works

• The CO Log — every change: cost, price, signed-before-work. FREE and UNSIGNED rows flag themselves; the month line shows what you captured and what you donated
• The Leakage Math — the freebie stream and the billed-near-cost stream, priced at your volume
• The Rules — a text counts as a signed CO ("Add the hose bib — $165. Reply YES"); the script that quotes in the same warm breath; full-margin pricing set off-site because a change order competes with nothing; the ONE deliberate freebie said out loud; and the photo-and-text rule that gets crews to stop giving work away
