See the price, the costs and what is still missing.

Bring the quote or billed price, actual listed costs and any payments. Review the arithmetic without turning unknowns into profit.

You check actual hours, payments and missing costs; a quote total cannot establish profit.

Example · not your saved work

$12,000 quote; $5,200 materials; $1,200 worker; $600 dumpster; five owner days.

The exact dumpster correction

$12,000 − $5,200 − $1,200 − $600 = $5,000 before owner labor and unlisted costs.
Change only the dumpster to $800: the remainder is $4,800.
Cash received and owner hours remain unknown.
