Picture this: You've just completed a $500,000 construction project. The work is done, your crew has moved on, but you've only received $450,000. Where's the other $50,000? It's sitting in retention and if you're not tracking it properly, you might never see it.
For construction owners, general contractors, and subcontractors working with AIA contracts, retention isn't just a line item on payment applications. It's working capital that's temporarily out of reach, and in today's environment of rising material costs and razor-thin margins, every dollar matters. Poor retention accounting doesn't just create compliance headaches, its can strangle your cash flow and distort the financial picture you're presenting to banks and sureties.
In this article, you'll learn the proper way to account for retention in AIA contracts, avoid critical mistakes that trap cash on your balance sheet, and implement strategies to optimize your working capital.

Understanding Retention in AIA Contracts
Retention (also called retainage) is a percentage of each progress payment that owners or general contractors withhold as security until a project reaches substantial or final completion. In most AIA contracts, retention typically ranges from 5% to 10% of each payment application.
The purpose is straightforward: retention protects owners and general contractors against incomplete work, defects, or contractor default. It's essentially a security deposit that gets released once you've fulfilled your contractual obligations which might include substantial completion, final completion, lien waivers, or punch list resolution.
How Retention Appears in AIA Documentation
If you're working with AIA contracts, you're familiar with the G702 (Application and Certificate for Payment) and G703 (Continuation Sheet) forms. Here's how retention flows:
Line D (Work Completed): The gross amount you've earned based on percentage of completion
Line E (Retention): The percentage withheld (e.g., 10% of Line D)
Line G (Current Payment Due): Net amount after retention (Line D minus Line E)
Many contractors focus only on Line G, the cash they're about to receive and forget that Line D represents revenue they've actually earned. This is the first critical mistake.
Common Retention Release Structures
Standard Retention: Full percentage withheld throughout the project, released at final completion
Milestone-Based Reduction: Retention drops after hitting benchmarks (e.g., from 10% to 5% after 50% completion)
Partial Release at Substantial Completion: 50% of retention released when project is substantially complete
Zero Retention Programs: Performance-based arrangements where retention is waived for contractors with proven track records
The problem? Many contractors don't have systems to track which structure applies to which project, when release triggers occur, or how much retention is sitting with each client.
The Accounting Challenge: Where Contractors Go Wrong
Mistake 1: Recording Only Cash Received
The most damaging retention accounting mistake is recording revenue only when cash hits your bank account. This feels intuitive money in, money recorded but it's wrong.
Generally Accepted Accounting Principles (GAAP) require construction companies to use accrual accounting and the percentage-of-completion method. This means you must recognize revenue when you earn it when the work is performed not when you receive payment.
When you only record cash received, you're:
Understating revenue by the full retention amount
Distorting profit margins on your work-in-progress (WIP) reports
Misrepresenting project performance to banks, sureties, and stakeholders
Creating compliance issues that can affect bonding capacity
Mistake 2: Losing Track of Retention Balances
Retention has a nasty habit of getting lost. Unlike regular accounts receivable that you chase every 30-60 days, retention can sit for months or even years on long-term projects. Without systematic tracking, contractors often fail to bill for retention release when triggers are met, miss substantial completion deadlines, or forget about retention on completed projects entirely.
The real-world consequence: The average commercial contractor has 8-12% of their annual revenue tied up in retention at any given time. For a $5 million contractor, that's $400,000 to $600,000 of working capital sitting idle money that could be paying down debt, purchasing materials, or making payroll.
Mistake 3: Improper Balance Sheet Classification
When contractors do track retention, they often lump it into regular accounts receivable. This creates problems because retention isn't the same as standard A/R. Retention is contractually withheld and won't be paid until specific conditions are met sometimes 6, 12, or even 24 months later.
Proper financial reporting requires distinguishing between current assets (retention expected within 12 months) and non-current assets (retention on multi-year projects). This classification affects your current ratio and working capital calculations critical metrics that banks and sureties scrutinize.
Proper Retention Accounting Method
Let's walk through the correct way to account for retention using proper accrual accounting.
Step 1: Revenue Recognition When Work is Performed
Record 100% of earned revenue immediately when work is performed, following the Percentage-of-Completion method.
Timing | Journal Entry |
When Work is Performed | Debit: Contract Assets - $100,000 Credit: Revenue - $100,000 |
This records the full amount you've earned, regardless of retention. You're recognizing economic reality, you've created $100,000 in value not just cash movement. Skipping this step understates your revenue and distorts WIP reports.
Step 2: Billing the Client via AIA G702/G703
When you submit the AIA G702/G703, you separate the expected cash from the retained amount.
Timing | Journal Entry |
When Submitting AIA G702/G703 | Debit: Accounts Receivable - $90,000 Debit: Retention Receivable - $10,000 Credit: Contract Assets - $100,000 |
The $10,000 retention goes into its own dedicated receivable account, not lumped with regular A/R. This is how you track retention by project and avoid losing money. Your A/R of $90,000 reflects what you'll receive in 30 days; retention has different payment terms.
Step 3: Receiving Payment
You record the actual cash received, while the retention balance remains on your books, waiting for the release trigger.
Timing | Journal Entry |
When Net Payment Arrives | Debit: Cash - $90,000 Credit: Accounts Receivable - $90,000 |
Step 4: Retention Release
Once release conditions are met (substantial completion, final completion, lien waivers submitted):
Timing | Journal Entry |
At Completion/Release Trigger | Debit: Cash - $10,000 Credit: Retention Receivable - $10,000 |
Now you've collected the full $100,000 you earned, and your books accurately reflect the complete transaction from start to finish.
Cash Flow Management Strategies
Proper accounting is only half the battle. Here's how to actively manage retention to optimize your working capital:
Strategy 1: Implement Aggressive Retention Tracking
Create a dedicated retention aging report showing project name, total retention withheld, aging buckets (0-90 days, 91-180 days, 181+ days), expected release date, and status of release conditions.
Review this report monthly not quarterly, not annually. Set calendar reminders for 30 days before substantial completion dates so you can prepare documentation in advance. The moment you hit a release trigger, submit your retention billing immediately.
Strategy 2: Negotiate Better Retention Terms Upfront
Before you sign the contract, everything is negotiable. Use these tactics:
Reduce the rate: Request 5% instead of 10%, or 3% if you have a strong track record
Front-load the release: Negotiate 50% retention release at substantial completion
Tie to milestones: Link retention reduction to specific project milestones
Earn zero retention: If you have excellent bonding and strong financials, push for zero retention programs
Strategy 3: Factor Retention Into Your Bidding
Many contractors underbid because they don't account for the true cost of retention. Consider the time value of money if retention is held for 6-12 months, calculate the opportunity cost or interest expense on that capital. Build these costs into your overhead or markup.
Strategy 4: Use Retention Metrics as Key Performance Indicators
Track these metrics monthly:
Retention as % of total receivables: High percentages indicate you're over-leveraged
Average days to retention release by client: Identifies slow-paying clients
Total retention outstanding: Should decrease as projects complete
Every day that retention sits unreleased is a day you're not deploying that capital productively. For a $3 million contractor with $300,000 in retention, releasing that capital even one month earlier translates to $2,000-$2,500 in avoided interest costs (at 8-10% annual rates).
Compliance and Best Practices for AIA Contracts
WIP Report Accuracy for AIA Projects
Your WIP schedule is the single most important financial report in construction. Banks review it monthly. Sureties scrutinize it before bonding new projects.
Proper retention accounting on AIA contracts is essential for accurate WIP reporting because over/underbilling calculations require correctly stated contract assets and billings. When retention from AIA G702/G703 applications isn't properly recorded, your WIP reports will show distorted gross profit margins and incorrect over/underbilling positions red flags that can limit your bonding capacity.
AIA Billing Documentation Requirements
For every AIA contract, maintain organized records of:
All AIA G702/G703 applications showing retention calculations from each billing period
Contract sections specifying retention rates and release conditions
Substantial completion certificates documenting when retention release triggers are met
Final lien waivers from subcontractors and suppliers
Correspondence regarding retention release requests and any disputes
This documentation protects you when owners or general contractors delay retention release beyond contractual terms. Without proper AIA billing records, you have no leverage to enforce release conditions.
Retention Release Triggers in AIA Contracts
Different AIA contract documents have different retention release provisions. Know which applies to your projects:
AIA A101: Standard form often releases retention at substantial completion
AIA A401: Subcontractor agreement may tie retention to prime contract release
Custom modifications: Many contracts modify standard AIA retention terms
Review your AIA contract's retention language before project start. Set calendar reminders for substantial completion dates, and prepare your G702/G703 retention release billing in advance so you can submit immediately when triggers are met.
