Work in Progress (WIP) Reporting: Understanding Your True Financial Position
The WIP schedule is the most important financial document for contractors and project-based businesses. Learn how to build it, interpret it, and use it to manage your business.
If you run a construction company, engineering firm, or any project-based business, your standard financial statements only tell part of the story. The income statement shows revenue and expenses, but it does not reveal whether your jobs are actually profitable or whether you are billing appropriately for work completed.
That is where Work in Progress (WIP) reporting comes in. The WIP schedule bridges the gap between job costing and financial reporting, showing you the true economic position of every active project. As covered in our complete guide to job costing, accurate cost tracking is the foundation—WIP reporting translates that data into financial insight.
Why WIP Matters
Banks and bonding companies scrutinize your WIP schedule more than any other financial document. It reveals whether you are overbilled or underbilled, whether your jobs are profitable, and whether your revenue recognition is accurate. Problems on the WIP schedule can reduce bonding capacity, trigger loan covenant violations, or signal deeper operational issues.

What Is a WIP Schedule?
A WIP schedule (also called a WIP report or schedule of contracts) is a detailed job-by-job analysis that shows contract values, costs incurred, estimated costs to complete, and the resulting revenue recognition and billing position for each active project.
WIP Schedule Components
The WIP schedule aggregates these figures across all active jobs to show your total work in progress, total over/underbilling position, and estimated gross profit in backlog.
The Percentage of Completion Method
The percentage of completion (POC) method is the accounting standard for long-term contracts in construction and project-based industries. Under POC, you recognize revenue proportionally as work is completed rather than when the project finishes or when you receive payment.
POC Revenue Recognition Formula
Percent Complete = Cost to Date / Estimated Total Cost
Earned Revenue = Contract Value x Percent Complete
Revenue This Period = Earned Revenue - Revenue Previously Recognized
Example: POC in Action
Project: Commercial building renovation
Contract value: $2,000,000
Estimated total cost: $1,600,000
| Period | Cost to Date | % Complete | Earned Revenue | Revenue This Period |
|---|---|---|---|---|
| Month 1 | $320,000 | 20% | $400,000 | $400,000 |
| Month 2 | $640,000 | 40% | $800,000 | $400,000 |
| Month 3 | $1,120,000 | 70% | $1,400,000 | $600,000 |
| Month 4 | $1,600,000 | 100% | $2,000,000 | $600,000 |
Total gross profit: $400,000 (20% margin). Recognized proportionally as costs are incurred.
Cost-Based vs. Output-Based
The cost-to-cost method (shown above) is most common in construction. Some industries use output-based measures like physical units completed or milestones achieved. The key is that percent complete must reasonably reflect actual progress—not just time elapsed or cash collected.
Cost-to-Complete Estimates: The Critical Input
The estimated cost to complete is the most important—and most subjective—number on your WIP schedule. This forecast of remaining costs drives your percent complete, earned revenue, and reported profit. Get it wrong, and your entire financial picture is distorted.
Why Cost-to-Complete Is Hard
- Optimism bias: Project managers naturally underestimate remaining work
- Unknown unknowns: Problems not yet discovered cannot be estimated
- Change orders pending: Scope changes in negotiation create uncertainty
- Subcontractor risk: Sub performance affects your costs
- Weather and delays: Schedule compression increases costs
Best Practices for Cost-to-Complete
Update Monthly
Review every active job monthly. Do not let estimates go stale. What was true last month may not be true today.
Challenge Assumptions
Have finance or a CFO review estimates with project managers. Push back on "everything is fine" when data suggests otherwise.
Track Fade History
If jobs historically lose 3% margin in the final 20% of completion, build that pattern into estimates for current jobs.
Document Assumptions
Record the basis for estimates. When estimates change, document why. This creates accountability and audit trail.
Understanding variance analysis between estimates and actuals helps improve future cost-to-complete accuracy and identify patterns in estimating errors.
Revenue Recognition Timing
Under percentage of completion, revenue is recognized when earned—meaning when work is performed—not when billed or when cash is received. This creates timing differences between revenue, billings, and cash flow that the WIP schedule reconciles.
Three Different Amounts
Earned Revenue (POC)
Revenue recognized based on work completed. This appears on your income statement.
Billings
Invoices sent to customers. May be ahead of or behind earned revenue.
Cash Collected
Actual payments received. Often 30-90 days after billing due to payment terms.
The difference between earned revenue and billings creates the over/underbilling position explained in our guide to overbilling and underbilling. This position is critical for understanding your true financial health.
Completed Contract Alternative
For shorter contracts (typically under one year), some companies use the completed contract method, recognizing all revenue and profit when the project finishes. This is simpler but can create lumpy financial results and is not allowed for GAAP financial statements on longer contracts.
WIP Adjustments
Each month, changes in cost-to-complete estimates, contract values, or billing positions create WIP adjustments that affect your financial statements. These adjustments can significantly impact reported revenue and profit.
Types of WIP Adjustments
Cost Overruns Recognized
When estimated total cost increases, gross profit decreases. If the job is 50% complete, you recognize 50% of the profit reduction immediately. This is called a "catch-up" adjustment.
Contract Value Increases
When change orders are approved, contract value increases and profit is recognized proportionally based on percent complete. Only recognize when change orders are formally approved and collectible.
Loss Job Recognition
If estimated total cost exceeds contract value, the entire loss must be recognized immediately—regardless of percent complete. Do not defer loss recognition.
Prior Period Adjustments
If prior estimates were materially wrong, you may need to adjust previously recognized revenue. Significant adjustments should be disclosed and explained.
Example: Cost Overrun Impact
Project: $1,000,000 contract, originally estimated at $800,000 cost (20% margin)
Month 3: 60% complete ($480,000 costs incurred), earned revenue = $600,000, gross profit recognized = $120,000
Revised estimate: Total cost now estimated at $900,000 (10% margin)
Adjustment needed: Total expected profit now $100,000. At 60% complete, should have recognized $60,000. Previously recognized $120,000. Current month adjustment: -$60,000 to gross profit.
Bank and Bonding Company Requirements
Banks and surety companies rely heavily on WIP schedules to assess contractor financial health. Understanding what they look for helps you present your business in the best light—and avoid surprises that could affect credit or bonding capacity.
What Banks Look For
Over/underbilling trend: Chronic underbilling signals cash flow risk
Job profitability: Are jobs actually making money?
Backlog quality: Margin expectations in remaining work
Estimate accuracy: History of adjustments
Concentration: Dependence on single large jobs
What Sureties Look For
Gross profit fade: Do jobs finish at estimated margins?
Work types: Experience in the types of work being bonded
Single job size: Largest job relative to capacity
WIP consistency: Stability in reporting over time
Aging: Are old jobs dragging on?
WIP Schedule Best Practices for External Review
- Clean presentation: Use a consistent format that is easy to read and follow
- Complete information: Include all required fields; do not leave blanks
- Explain variances: Provide notes on significant changes from prior periods
- Reconcile to financials: WIP-derived revenue should tie to income statement
- Show history: Provide comparative data when requested
Net Overbilling Position
A significant net overbilled position (billings exceeding earned revenue company-wide) is a yellow flag for bankers and sureties. It means you have collected cash for work not yet performed—creating an obligation to complete that work. While normal in construction, excessive overbilling can signal front-loading problems or cash flow dependence on future projects.
Putting It All Together
Effective WIP reporting requires discipline across the organization. Here is a monthly WIP review process that keeps your financial position accurate and transparent.
Monthly WIP Review Process
Project Manager Updates
Each PM updates cost-to-complete estimates for their jobs, documenting assumptions and known risks.
Finance Review
Finance or CFO reviews estimates against job cost data, challenging optimistic projections.
WIP Schedule Preparation
Calculate percent complete, earned revenue, and over/underbilling for each job.
Financial Statement Integration
Post WIP adjustments to the general ledger; reconcile to balance sheet and income statement.
Management Review
Leadership reviews WIP results, identifies problem jobs, and discusses implications.
This process connects to your broader job profitability analysis—the WIP schedule provides the data, but leadership must act on what it reveals.
