TL;DR: The four numbers a construction subcontractor owner needs monthly: gross margin by job (are the jobs making money?), overhead rate versus bids (is the bid model current?), AR over 45 days (is earned cash being collected?), and WIP position (are the financial statements accurate?). These four numbers, reviewed together monthly, give the owner the complete financial picture of the business without requiring accounting expertise.

Overview

What You Need to Know

The CEO Report dashboard SPM produces monthly shows these four numbers alongside 13-month trend lines for each. The owner spends 30-45 minutes reviewing the dashboard in the monthly CFO meeting. That is the 5 hours per month SPM clients spend on financials.
Gross margin by job — not just overall. Total gross margin for the period tells you whether the business made money. Gross margin by job tells you which jobs made money and which did not. A civil contractor with 23% overall gross margin but three jobs running at 12% and two at 32% needs to know which GC relationships and job types are profitable. SPM produces job-level gross margin monthly from ControlQore data.
Overhead rate versus bid model. What is in the bid model versus what SG&A actually was last month as a percentage of revenue. When these diverge the bid model needs updating. SPM recalculates overhead rate monthly from actual P&L data and flags when it differs from the rate in bids by more than 1-2 points.
AR over 45 days. Dollar amount of invoices outstanding more than 45 days. This number should be trending down or staying near zero. When it grows it means earned cash is not being collected and the business is funding GC payment terms from operating cash. SPM targets zero AR over 45 days through the weekly Monday collections call.
WIP position — net overbilled or underbilled. The net position across all active jobs: are jobs overbilled or underbilled in total? A net underbilled position means pay apps need to be submitted. A net overbilled position means billing is running ahead of work performed. Both are fine in moderation. Large swings month to month signal billing timing issues that need to be addressed.
FAQ

Frequently Asked Questions

What financial metrics should a construction subcontractor track monthly?
Four key metrics: gross margin by job (are jobs profitable?), overhead rate versus bid model (is pricing current?), AR over 45 days (is earned cash being collected?), and WIP position (are financial statements accurate?). These four together give a complete picture of financial health without requiring deep accounting knowledge.
What is the SPM CEO Report?
The CEO Report is a dashboard SPM produces monthly from ControlQore data showing the four key metrics plus 13-month trend lines for each. Clients review it in the monthly CFO meeting. The live version of the CEO Report tool is available at constructioncfo.net/ceo-report for clients to access their own dashboard.
How much time should a construction owner spend on financials?
Five hours per month with SPM. That includes reviewing the CEO Report dashboard in the monthly CFO meeting, reviewing the WIP schedule summary, and responding to action items from SPM. The owner does not handle bookkeeping, reconciliations, pay app submissions, or AR collections directly. SPM handles all of it.
What is the difference between a CFO dashboard and a P&L?
A P&L shows what happened last month. A CFO dashboard shows the four numbers that tell you what is happening now and what is likely to happen next. Gross margin by job shows current job performance before closeout. AR over 45 days shows what is collectible right now. WIP position shows whether the P&L is accurate. The overhead rate comparison shows whether bids are correctly priced going forward.
