What Is Retainage and Why It’s Used
Retainage keeps a small percentage of progress payments in reserve to ensure work is completed to spec. Clear retainage terms in the contract reduce disputes and help both parties plan cash flow.
- Typically 5–10% withheld from each progress payment
- Released at substantial or final completion per contract
- Applies to prime and subcontracts; check pass-through clauses
- Goals: quality assurance, timely completion, and clear closeout
Common Retainage Rates & Contract Rules
Retainage terms live in the contract. Know the percentage, milestones for partial release, and any special rules for stored materials or change orders.
- Standard rate (e.g., 10%) may step down after a % complete threshold
- Partial releases may occur at milestones (e.g., MEP rough-in complete)
- Stored materials may carry retainage at the same or adjusted rate
- Change orders should mirror base retainage terms unless specified
How Retainage Appears on AIA/Progress Billing
On AIA pay apps, retainage is shown on the G702 summary and within G703 line items tied to the Schedule of Values (SOV). Accurate math prevents delays.
- Show retainage % and dollar value on the G702 Application for Payment
- Apply retainage per SOV line on the G703 Continuation Sheet
- Adjust retained amounts when change orders add scope/value
- Carry forward balances cleanly month to month to avoid disputes
Retainage Release & Closeout
Retainage is typically released at substantial completion, with any remainder held until final completion. Documentation and timely punch list work speed up release.
- Deliver closeout docs: warranties, O&M manuals, as-builts
- Complete punch list items and obtain sign-offs
- Verify lien waivers and vendor/sub balances
- Request partial or final release per contract language
Common Retainage Mistakes
Retainage disputes often stem from inconsistent math or unclear documentation. Standardize your process across all projects.
- Applying different percentages across SOV lines
- Not updating retainage after change orders
- Forgetting stored-materials retainage rules
- Missing paperwork at closeout delays release

FAQs About Retainage
Is retainage required on every project?
No. It depends on the contract and jurisdiction. Many commercial and public projects include retainage by default, but terms can be negotiated.
Can retainage be reduced during the project?
Sometimes. Contracts may allow step-downs (e.g., from 10% to 5%) after a completion threshold or at specific milestones.
How do I get retainage released faster?
Stay proactive: keep SOV math accurate, submit clean pay apps, finish punch list items, and deliver closeout docs on time to avoid approval delays.
TL;DR Recap
- Retainage holds back 5–10% to ensure quality and completion
- Spell out rates, milestones, and release terms in the contract
- Show retainage clearly on AIA/Progress billings (G702/G703)
- Werx automates retainage across SOV lines, changes, and stored materials
