Typical payment terms for subcontractors in commercial construction follow a Net 30 billing cycle with 5-10% retainage, monthly pay application submission, and conditional lien waivers. But "typical" varies by project size, region, and trade. The Construction Financial Management Association found that GCs who align their payment terms with industry norms attract 22% more competitive bids than those using non-standard or overly aggressive terms.

This tool guide breaks down what typical looks like across the industry, where your terms should match the norm, and where best practices push beyond typical to reduce risk.

Industry Standard Payment Terms: The Baseline

These are the payment terms most commonly used in commercial construction across the United States.

Payment Term	Typical Standard	Range	Best Practice
Payment timing	Net 30 from approval	Net 15 to Net 45	Net 30 or faster
Billing cycle	Monthly (calendar month)	Semi-monthly to monthly	Monthly with fixed dates
Retainage percentage	10% until 50%, then 5%	5-10% throughout	Reduce to 5% at 50% completion
Retainage release	At substantial completion	Final completion to 30 days after	Within 30 days of sub's completion
Pay app submission deadline	25th of month	20th-last day of month	25th with 5-day GC review
Lien waiver type	Conditional with pay app	Varies by state	State-mandated forms
Change order markup	10-15% O&P	5-20%	10% self-performed, 5% lower-tier
Interest on late payment	1-2% per month	0-2%	Match state statutory minimum
Final payment timeline	30 days after close-out	30-60 days	30 days maximum

These numbers come from industry surveys conducted by AGC, CFMA, and NASBP between 2024 and 2025. Regional variations exist, but these figures represent the national median.

Best Practice 1: Set Payment Timing That Attracts Good Subcontractors

Payment timing directly affects your subcontractor pool. Subs with the best crews, equipment, and track records have choices. They pick GCs who pay on time.

Net 30 from approved pay application is the standard. Some GCs push this to Net 45 or even Net 60. That saves short-term cash flow but costs long-term competitiveness. Subcontractors build financing costs into their bids when payment terms are slow.

A GC paying Net 30 on a $500,000 subcontract saves the sub roughly $2,500 in financing costs compared to Net 60 terms. Many subs pass that savings through in their bid price. Faster payment does not just improve relationships; it lowers project costs.

Best practice: Pay subcontractors within 7 business days of receiving owner payment, or within 30 calendar days of approving the pay application, whichever comes first. This gives subs certainty regardless of owner payment delays.

Best Practice 2: Structure Retainage to Balance Risk and Cash Flow

Retainage protects the GC against incomplete or defective work. But excessive retainage harms subcontractor cash flow and can trigger disputes.

The typical approach holds 10% retainage until the project reaches 50% completion, then reduces to 5%. Retainage releases after the subcontractor achieves substantial completion of their scope, completes punch list items, and submits a final lien waiver.

Best practices push beyond typical:

Track retainage by subcontractor, not just by project. A mechanical sub who finishes at 60% of the overall project timeline should not wait for retainage until the project hits substantial completion. Release retainage when that specific sub completes their scope.

Set a calendar deadline for retainage release. "Within 30 days of subcontractor's substantial completion" is better than "upon project completion." The latter can hold retainage for months after the sub finishes.

Do not hold retainage on change orders separately from the base contract. Some GCs retain on change orders even after reducing retainage on the base contract. This creates accounting complexity and sub frustration.

Best Practice 3: Use Fixed Calendar Dates for Billing

Vague billing schedules cause missed deadlines and delayed payments. Fix your calendar.

The most effective billing schedule uses these dates:

25th of each month: Subcontractor pay application due to GC
1st-5th of following month: GC review and approval period
5th-10th: GC submits consolidated pay application to owner
10th-15th: Owner review period
By the 30th: Owner processes payment to GC
Within 7 business days of receipt: GC pays subcontractor

Post this schedule in the subcontract, at the preconstruction meeting, and in your project management system. Every participant should know every date.

When a subcontractor misses the 25th deadline, their billing moves to the next cycle. This rule must be enforced consistently. Accepting late pay apps for some subs but not others creates fairness complaints and legal exposure.

Best Practice 4: Require Compliant Lien Waivers Every Cycle

Lien waiver collection protects the GC and the owner from duplicate payment claims. Typical practice collects waivers, but best practice collects the right waivers at the right time.

With every pay application, require:

A conditional lien waiver from the sub for the current billing period
An unconditional lien waiver from the sub for the prior billing period
Conditional lien waivers from all lower-tier subs and suppliers for the current period

Track waiver collection digitally. Paper waivers get lost, misfiled, or submitted in non-compliant formats. A digital tracking system flags missing waivers before payment processing and stores them for audit access.

States with mandatory waiver forms include California (Civil Code 8132-8138), Florida (Chapter 713), Texas (Property Code Chapter 53), and Georgia (O.C.G.A. 44-14-366). Using the wrong form can make the waiver unenforceable.

Best Practice 5: Define Change Order Payment Before It Is Needed

Most GC-subcontractor disputes involve change orders. Setting payment terms before the first change request prevents arguments about pricing, markups, and billing.

Typical change order terms allow 10-15% markup for overhead and profit on self-performed work and 5-10% on work subcontracted to lower-tier subs. These percentages should be stated in the subcontract.

Best practice also addresses:

Time and materials caps. When change order work is performed on a time and materials basis, set a not-to-exceed amount. This prevents open-ended billing.

Pricing response timelines. Give the subcontractor 5-10 business days to price a change order proposal. This prevents delays in the change management process.

Billing method. Change orders appear as separate line items on the schedule of values and get billed through the regular monthly pay application. No separate invoicing.

Best Practice 6: Build a Pay Application Review Process

Typical practice has the PM review pay applications alone. Best practice adds structure.

Create a review checklist that the PM completes for every pay application:

Does the billed percentage match field observations?
Are stored materials documented with invoices, photos, and insurance?
Is the conditional lien waiver for the current period attached?
Is the unconditional lien waiver for the prior period attached?
Do change order line items match approved change orders?
Is retainage calculated correctly?
Are any back-charges applied correctly?

This checklist takes 15-20 minutes per pay application. It catches errors before they become disputes. SubcontractorAudit automates this review against your payment terms, flagging discrepancies for PM attention.

How the Pay App Calculator Supports Best Practices

The Pay App Calculator helps GCs verify subcontractor pay applications against contract values, approved changes, and retainage requirements. Enter the original contract amount, approved change orders, prior billings, and current billing. The tool calculates the correct retainage, verifies that billing does not exceed the contract balance, and flags over-billing.

Use the calculator during every pay cycle to maintain accuracy and consistency across all subcontractors.

FAQs

What is the standard retainage percentage for subcontractors? The most common retainage structure is 10% until the project reaches 50% completion, then a reduction to 5%. Some projects use a flat 5% throughout. Several states cap retainage by law. Florida limits retainage to 10% until 50% complete, then 5%. Federal projects follow agency-specific rules. Always verify state caps before setting retainage terms.

How long should a GC take to review a subcontractor pay application? Best practice is 5-7 business days from receipt. Longer review periods delay the entire payment chain and may violate state prompt payment laws. If a pay application requires significant revision, return it to the sub with specific comments within the review period rather than holding it indefinitely.

Is it legal to pay subcontractors slower than the typical Net 30? Many state prompt payment laws set maximum payment timelines that cannot be extended by contract. If state law requires payment within 30 days, a contract term saying Net 60 is unenforceable. Even where longer terms are legal, they increase sub bid prices, reduce subcontractor quality, and create lien risk. Net 30 or faster is both the legal and practical best practice.

What markup should a GC allow on change orders? Industry standard is 10-15% overhead and profit on self-performed work and 5-10% on work subcontracted to lower-tier subs. Federal projects typically allow 10% O&P on self-performed and 5% on subcontracted. Set these percentages in the original subcontract to avoid negotiations on every change order.

Should payment terms differ between large and small subcontractors? The core terms (payment timing, retainage, lien waivers) should be consistent. However, you may adjust stored materials thresholds, billing frequency, and change order pricing methods based on subcontract value. A $2 million mechanical sub may warrant monthly billing with stored materials provisions, while a $15,000 painting sub may work better with milestone billing and no stored materials allowance.

How can I track payment terms compliance across multiple projects? Use a digital compliance platform that monitors billing deadlines, retainage calculations, lien waiver collection, and payment timelines across all projects and subcontractors. Manual tracking with spreadsheets works for 1-2 projects but breaks down at scale. SubcontractorAudit provides this tracking with automated alerts and compliance dashboards.
