TL;DR: SPM provides fractional CFO services for insulation contractors doing $1M-$12M in commercial new construction. Job costing by square feet by type and R-value in ControlQore, overhead rate including all real costs, WIP reporting monthly, and AR collection system that clears the backlog in 30 days. Most insulation clients find their first month's AR collection exceeds the annual SPM fee.

Insulation

The CFO for
Insulation Contractors.

You bid by the square. Your margin lives or dies in the field every week. If you find out a job is losing money at closeout it is too late. We make it visible in week two.

The Problem

What Kills Insulation Margins

Most insulation do not know a job is losing money until it is done. The estimate looked right. The crew was working. But the actual cost per square feet by type and R-value was running over estimate for three weeks and nobody knew it until closeout.
01

No SF Cost Tracking by Insulation Type

You bid batt insulation at $0.82/SF and spray foam at $2.40/SF. You have no visibility into whether spray foam areas came in at estimate or 30% over due to substrate prep issues. At closeout the job blended and you cannot explain where the margin went.

02

Substrate Prep Not Billed Separately

The exterior wall substrate required additional cleaning and priming before spray foam application - 8,400 SF at 45 minutes per 100 SF. That prep work was in the scope of work but not a separate line in the SOV. You funded $6,200 in prep labor from margin rather than from a separate pay app line.

03

Material Waste Variance From Estimate

Spray foam application waste runs 8-12% on standard geometry and 15-22% on irregular geometry. If the estimate used 8% waste on an irregular-geometry project you funded the difference from margin without knowing it until closeout.

The Fix

How SPM Builds the Insulation Financial System

SPM builds ControlQore cost codes aligned to the insulation estimate structure so actual cost per square feet by type and R-value posts weekly against estimated cost. Variance is visible in week two.
ControlQore cost codes by insulation type and SF. Batt by R-value, blown-in, spray foam by type, board insulation - each as separate cost codes. Actual cost per SF by type posts weekly. When spray foam runs over estimate the variance is visible in the cost code detail.
Substrate prep as a separate billable item. SPM reviews every insulation subcontract SOV for substrate prep allocation. If prep work is included in the scope without a separate SOV line item SPM negotiates a separate line before execution. Substrate prep is a direct cost that should be billed at occurrence not absorbed into the SF rate.
Material waste tracking by project geometry. Waste factor by project geometry documented at bid and tracked at installation. When actual waste exceeds the estimated factor by more than 5 points a cost variance is documented and a change order is evaluated.
Pricing

What It Costs

Priced by last 12 months of revenue. ControlQore billed separately at ~$100/month per $1M. SPM does not handle payroll.

FAQ

Frequently Asked Questions

What does a CFO for insulation contractors do?
A fractional CFO for insulation contractors builds the job costing structure aligned to the estimate - cost codes by square feet by type and R-value - so actual cost per unit is visible weekly against estimated cost per unit. They manage WIP reporting, overhead rate calculation, billing calendar, and monthly cash flow. The result: you know which jobs are winning and which are losing before you cannot do anything about it. All SPM clients run on ControlQore - purpose-built for construction job costing at $1M-$12M.
What overhead rate should insulation contractors use?
Insulation Contractors at $1M-$3M typically run 12-14% overhead. The most common errors are missing owner compensation at market rate and not including equipment depreciation or vehicle fleet in the SG&A calculation. Each of those understates the real overhead rate and underprices every bid.
What are the most common cash flow problems for insulation contractors?
Three consistent problems: schedule of values that underbills early phases which are the most cash-intensive work, overhead rate below actual because ownership costs are not fully included, and AR sitting uncollected at 45+ days with no follow-up system. Most insulation contractors have all three simultaneously. SPM fixes all three in the first 60 days.
What gross margin should insulation contractors target?
Insulation Contractors at $1M-$12M in commercial new construction typically target 22-27% gross margin. Margin below the lower end of that range usually indicates a markup problem, an overhead rate understatement, or job costing that is not capturing all direct costs accurately.
Do you handle payroll?
No. SPM does not handle payroll. We have vetted partners including prevailing wage and Davis-Bacon integrations that connect directly with ControlQore at additional cost.
How long does onboarding take?
60 days. We migrate your books to the start of your last taxable year, build your ControlQore job costing structure, and get you fully operational in two months.
What software do you use?
All SPM clients run on ControlQore - purpose-built for construction job costing and WIP reporting at $1M-$12M. More capable than QuickBooks for job costing, more affordable than Sage. We set it up and manage it.
Do I need clean books to start?
No. Most clients come with messy books and no job costing. That is exactly what onboarding is for.
