Percentage of Completion (POC) accounting is a revenue recognition method specifically designed for long-term
construction contracts that extend beyond a single accounting period. This method allows contractors to
recognize revenue and expenses proportionally as work progresses, providing a more accurate financial picture
than waiting until project completion.
The Alliance for Contractors ecosystem provides comprehensive POC accounting solutions that automate
calculations, optimize revenue recognition, and integrate seamlessly with progress billing systems. This
approach ensures contractors maintain accurate financial reporting while maximizing cash flow and profitability
throughout project lifecycles.
1. Revenue Recognition Accounting Method Setup
1.1 Understanding Percentage of Completion Method
The Percentage of Completion method recognizes revenue based on the progress of contract completion rather than at
the completion date. This method is required under Generally Accepted Accounting Principles (GAAP) for long-term
contracts when:
Reliable estimates of progress and costs can be made
Contract duration extends beyond one accounting period
The contractor has enforceable rights and obligations
Collection of payment is reasonably assured
1.2 Key Components of POC Setup
Contract Revenue Recognition
Total contract revenue includes the initial contract amount plus approved change orders, claims, and incentive
payments that are probable of collection.
Cost Accumulation System
Establish comprehensive cost tracking for:
Direct materials and labor costs
Subcontractor expenses
Equipment costs and depreciation
Indirect costs allocated to the project
Progress Measurement Methods
Select the most appropriate method for measuring completion:
Cost-to-Cost Method: Most common, based on costs incurred vs. total estimated costs
Units of Work Performed: Based on physical completion milestones
Efforts Expended: Based on labor hours or machine hours
2. Long-Term Construction Contracts
2.1 Contract Classification
Long-term construction contracts typically include:
Progress billing systems must align with POC accounting requirements while maintaining positive cash flow:
Billing Frequency Options
Monthly Billing: Most common for long-term projects
Milestone Billing: Based on completion of specific phases
Percentage Completion Billing: Directly tied to POC calculations
Billing Components
Current period work completed
Stored materials (if applicable)
Approved change orders
Less previous billings
Retention withholding
Alliance Integration Advantage
The Alliance for Contractors platform automatically synchronizes progress billing with POC calculations,
ensuring billing accuracy and reducing administrative overhead. Real-time integration between project
management, accounting, and billing systems provides seamless workflow automation.
3.2 Billing vs. Revenue Recognition Timing
Understanding the difference between billing and revenue recognition is crucial:
Overbilling Situation: When billings exceed earned revenue (creates a liability)
Underbilling Situation: When earned revenue exceeds billings (creates an asset)
Balanced Billing: When billings approximate earned revenue
4. Cost-to-Cost Method Implementation
4.1 Cost-to-Cost Calculation Framework
The cost-to-cost method is the most widely used approach for measuring completion percentage:
Revenue Recognized = Total Contract Revenue × Completion %
Current Period Revenue = Total Revenue Recognized - Previously Recognized Revenue
4.2 Cost Categories and Inclusion Criteria
Includable Costs
Direct labor and benefits
Direct materials incorporated into the work
Subcontractor costs
Equipment usage and depreciation
Allocated indirect costs
Excludable Costs
General and administrative expenses not specifically allocable
Interest expense
Costs of materials not yet incorporated
Advance payments to subcontractors for unperformed work
4.3 Estimate Revision Procedures
Regular estimate revisions are essential for accurate POC accounting:
Monthly Reviews: Assess progress and cost performance
Quarterly Comprehensive Reviews: Detailed analysis of remaining costs
Change Order Integration: Update estimates for approved changes
Loss Recognition: Immediate recognition of anticipated losses
5. Completion Percentage Calculations
5.1 Calculation Methodologies
Method 1: Simple Cost-to-Cost
Most straightforward approach for homogeneous projects:
Element
Example Amount
Total Contract Value
$1,000,000
Total Estimated Costs
$800,000
Costs Incurred to Date
$400,000
Completion Percentage
50% ($400,000 ÷ $800,000)
Revenue to Recognize
$500,000 ($1,000,000 × 50%)
Method 2: Weighted Progress Method
Used for projects with distinct phases requiring different measurement approaches:
Assign weights to different project phases
Calculate completion for each phase
Apply weighted average for overall completion
5.2 Common Calculation Challenges
Front-End Loading
Address situations where early costs don't represent proportional progress:
Exclude mobilization costs from POC calculations
Use modified completion methods for setup-intensive projects
Apply progress caps for initial project phases
Material Storage and Procurement
Handle materials purchased but not yet installed:
Exclude stored materials from cost-to-cost calculations
Include only when materials are incorporated into the work
Track stored materials separately for billing purposes
