Margins + Leakage

Underpriced work

A full schedule can still lose if the wrong work fills it.

Executive lens

A useful brief turns the issue into a decision.

Trap

Taking every job because crews need work.

Signal

Avg job margin

Move

Set minimum margin by work type

Rule

Busy is not the same as profitable.

Why it matters

Taking every job because crews need work.

Stakes

Leakage rarely arrives as one dramatic failure. It arrives as small discounts, labor overruns, rework, vendor creep, stale pricing, and overhead that never gets reset.

Why it gets missed

The business stays busy, so the owner assumes the machine is working. Busy hides leakage until the month closes and there is less left than expected. In this case, the practical trap is simple: taking every job because crews need work..

Field pattern

Use a simple model: compare more volume at the same margin against modest sales growth plus a margin improvement. The point is not that margin always wins. The point is that growth should compete against easier profit already inside the business.

Numbers to watch

The metric is useful only when it changes behavior.

Avg job margin

Shows whether the work mix is improving or just filling the calendar.

Capacity used

Reveals whether scarce capacity is being spent on the right jobs.

Close rate

Connects sales effort to pricing quality, lead quality, and follow-up discipline.

Operating moves

What to make visible before the next decision.

Move 01

Set minimum margin by work type

Move 02

Quote capacity-constrained work higher

Move 03

Stop hiding discounts inside scope

Owner questions

Use the brief in a real review.

1

If avg job margin moved this week, what decision would change?

2

Which person, process, or rule owns set minimum margin by work type?

3

What would make this number untrustworthy right now?

4

If nothing changes for 90 days, what gets harder for the owner?
