Committed Costs Reporting: Stop Construction Budget Overruns

Right now, your superintendent has $200K in open POs for materials that haven't been invoiced yet. Your project manager signed a $150K subcontract last week that accounting hasn't entered. Your "profitable" $2M project? It's already over budget, but your reports won't show it until next month.
This article shows you how to:Â Track every dollar you've committed (not just spent), spot budget problems 60 days earlier, and use real-time data to save projects before they go underwater.

What Are Committed Costs in Construction?
Committed Costs = Legal obligations you must pay (Purchase Orders + Subcontracts) |
Actual Costs = Invoices you've already paid
Most contractors only track actual costs in their accounting system, but this is where the problem starts. If you're not tracking committed costs, you're making decisions based on outdated data.
Why Committed Costs Matter to Your Bottom Line
When you only see actual costs, you're driving blind. Here's an example:
Day 1:Â Your superintendent orders $50K in steel.
Day 30:Â The steel is delivered to the job site.
Day 60:Â The invoice arrives at your desk.
Day 75:Â The accountant enters the invoice, and you see you're over budget.
By Day 75:Â You've lost 10 weeks to fix the problem. The damage is done.
With 8-12% quarterly material price swings in 2024-2025, waiting 60 days for updates can completely wipe out your profit margin.
Three Ways Committed Costs Can Kill Construction Profits
1. The Uncommitted Scope Disaster
The warning sign:
Your project is 60% complete.
But only 35% of your materials are locked in with POs.
What this means:Â The remaining 65% of materials are exposed to:
Price increases (8-12% in recent quarters)
Supply chain delays forcing premium pricing
Substitutions at higher cost
Rush delivery fees
Real case:Â A $2.5M commercial project had $750K uncommitted in April 2024. By July, prices jumped 15%. The result? A $200K profit became a $50K loss.
2. Duplicate Orders Draining Cash
How it happens:
Monday:Â Field super needs lumber, creates PO for $25K
Wednesday:Â PM doesn't know, orders same materials for $25K
Two weeks later:Â Both deliveries arrive
Next month:Â Both invoices get paid ($50K out the door)
Annual impact:Â GCs lose $150K-$200K yearly to duplicate orders across projects.
Why? No real-time system connecting field decisions to office visibility.
3. False WIP Reports Crushing Your Bonding
Your monthly WIP report shows:
Original Budget: $1,000,000
Actual Costs to Date: $650,000
Projected Final Cost: $950,000
Projected Profit: $50,000Â
The real numbers your accountant doesn't see:
Actual Costs: $650,000
Committed Costs (not invoiced): $380,000
Real Total: $1,030,000
Actual Profit: -$30,000Â
The consequence:
Your surety reviews your WIP schedule. They see the real committed numbers. They reduce your bonding capacity by 30%.
You lose the next bid opportunity.
How Real-Time Committed Costs Tracking Can Save Your Projects
Fix Problems Before They Become Disasters
Traditional approach:Â Wait for invoices to tell you what went wrong
Real-time approach:Â See commitments the day they're created
The difference:
Issue | Old Way | New Way |
Budget overrun detected | 60 days later | Same day |
Time to fix | None (too late) | 8+ weeks |
Average savings | $0 | $75K-$150K per project |
Benefits of Real-Time Tracking
1. Accurate WIP for Banks and Sureties
With committed costs tracked, your WIP is reliable, increasing bonding limits and ensuring faster approvals.
2. Cash Flow You Can Actually Predict
Predict upcoming payments and adjust your AP timing accordingly.
Example:
Week of Dec 23: $125K subcontract payments due
Week of Dec 30: $80K material invoices arriving
Week of Jan 6: $95K equipment rentals payable
Total visibility:Â $300K leaving in the next 3 weeks
3. Automated Red Flag Alerts
Your system watches 24/7, alerting you when:
A PO exceeds the cost code budget
Committed and actual costs exceed the project budget by 5%
Uncommitted scope exceeds your risk threshold
A subcontract change order creates budget exposure
Why Manual Tracking and Excel Always Fail
The Field-to-Office Information Black Hole
What actually happens:
In the field:Â Superintendent writes PO on a clipboard, which sits in the truck for 2 weeks, gets coffee-stained, and finally reaches the office.
In the office:Â Errors occur during data entry, and the PO is entered 3 weeks late.
Meanwhile, invoices arrive before the PO is even in the system. Accounting pays them, and you're over budget before you even know it.
The Spreadsheet Death Spiral
Month 1:Â "I'll track our POs in Excel"
Month 2:Â Three different versions floating around
Month 3:Â 12 separate spreadsheets across projects
Month 4:Â Field stops updating them
Month 6:Â No one knows which file is current
Month 8:Â Project manager quits, takes spreadsheet knowledge
Month 9:Â Complete chaos. You have zero visibility.
The fundamental problem:Â Excel can't connect fields to offices in real-time. It's just another manual process waiting to break.

Calculate Your Hidden Committed Costs Risk
The 5-Minute Exposure Assessment
Use this formula:
Total active project budgets × % scope not yet on PO × Expected material inflation rate = Your hidden risk exposure |
Example Calculation
Your numbers:
$8M in active project budgets
45% of scope not yet committed (no POs issued)
10% annual construction material inflation
Your calculation: $8M × 45% × 10% = $360,000
What this means:
You could lose $360K simply from price increases on materials and services you haven't locked in yet.
This assumes:Â Materials increase at 10% annually (conservative based on 2024-2025 volatility)
In reality:Â Some materials have spiked 15-20% in single quarters recently.
Run Your Own Numbers
Step 1:Â Add up all active project budgets: $___
Step 2:Â Estimate % of scope uncommitted: ___%
Step 3:Â Use 10% inflation estimate (or your own forecast): ___%
Your exposure:Â $___
Action:Â If this number is larger than your typical project profit, you need committed costs tracking immediately.
