CONCRETE FLATWORK CONTRACTOR NET PROFIT MARGIN.
Healthy net profit margin for concrete flatwork contractors runs 6.0–7.0% at $1M–$10M in revenue, below the 12% CFOS target. The single biggest compressor is a flat square-footage rate that absorbs decorative finish and sub-base prep premiums instead of billing them as separate line items.
Flatwork is sold at one square-footage number, but that number is asked to cover sub-base prep, standard finish, and any decorative upgrade all at once. When a job requires more prep than bid, or a decorative finish gets priced at the standard rate, the flat SF number quietly absorbs the difference. Net margin only improves once those cost categories are separated and billed on their own.
Net Profit Margin Formula: Net Profit ÷ Total Revenue × 100. Net margin measures what's left after every cost is paid, including overhead; gross margin only measures job-level cost before overhead absorption.

WHAT MOVES THIS NUMBER.
A flat SF rate absorbing multiple cost categories is the primary compressor
Sub-base prep, standard finish, and decorative or stamped finish all carry different costs, but a single square-footage rate treats them as one number. Any category that runs over its share of that blended rate erodes margin with no billing mechanism to recover it.
Above-benchmark flatwork contractors separate prep and finish into their own billing lines
Top performers price and bill sub-base prep, standard finish, and decorative premiums as distinct SOV lines, and they document weather-driven pour delays as change orders the same week they happen instead of absorbing the standby cost.
Check SOV line separation, weather hold documentation, and rate card accuracy first
If net margin is below benchmark, check whether prep and finish are billed as separate lines or blended into one SF rate, whether weather holds are filed as change orders, and whether the standard rate card reflects current finish-type cost data.
