What Is a Progress Payment and How Does It Work?

A progress payment in construction is a partial payment made to a contractor during a project, releasing funds as work is completed instead of holding everything back until the end. The contract sets the schedule, the contractor submits a formal application showing what has been built, an architect or engineer certifies it, and the owner pays the certified amount minus a holdback called retainage. That cycle repeats until the job is finished, keeping cash flowing to the contractor, subcontractors, and suppliers who would otherwise have to finance the entire job themselves.

How the Payment Schedule Gets Set

The payment schedule is locked into the contract before any work starts. A vague schedule is one of the fastest routes to a payment dispute, so the parties pick a structure that fits how progress can actually be measured on the specific job.

A milestone-based schedule ties each payment to a defined project stage: foundation pour, structural steel erection, roof completion. No verified milestone, no payment. This works well when the project has clear physical markers that are easy to inspect and hard to game.

A time-based schedule sets regular billing intervals, usually monthly. The contractor submits an application at the end of each period, and the amount reflects the value of work performed during that cycle. Monthly billing is probably the most common approach in commercial construction because it creates a predictable rhythm every party can plan around.

A percentage-of-completion schedule ties payments to the project’s overall completion status. If the project is certified 25% complete, the contractor has earned 25% of the total contract value, minus prior payments and retainage. This fits jobs where distinct physical milestones are hard to isolate but overall progress can be tracked through cost data or engineering estimates.

The Schedule of Values

The schedule of values, or SOV, is the backbone of nearly every progress payment calculation. It breaks the total contract price into individual line items — site work, concrete, electrical, mechanical, finishes — with a dollar value assigned to each one. Every payment request gets measured against it, and every dollar earned traces back to a specific line item.¹

Each billing period, the contractor reports what percentage of each line item has been completed. If the SOV allocates $200,000 to electrical rough-in and the contractor certifies 50% of that work is done, the earned value for that line item is $100,000. Add up the earned values across every line item, subtract prior payments and retainage, and you have the current payment amount. The SOV lets the architect or owner evaluate the payment request line by line rather than taking the contractor’s total on faith.¹

Front-End Loading

Contractors sometimes inflate the dollar values assigned to early-stage work on the SOV, a practice called front-end loading. The goal is to pull cash forward: if mobilization and early site work are overvalued relative to later trades, the contractor collects more money earlier in the project. Within reason, this is a common cash-flow strategy, and experienced project managers expect to see some degree of it.

Aggressive front-loading creates real problems. If the contractor walks off or gets terminated halfway through, the owner may have already overpaid relative to the work in place, leaving insufficient funds to hire a replacement. On federal and many public projects, excessive front-loading can cross into false claim territory, carrying steep civil and criminal penalties. Even on private work, owners who feel gamed will scrutinize every future request, slowing every payment cycle for the rest of the job.

The Payment Application and Certification

The formal payment request begins with the contractor assembling an application package. In the U.S. construction industry, AIA Document G702 is the standard form; it summarizes the contract status, including work completed to date, retainage, previous payments, change orders, and the current amount requested.² The companion form, G703, provides the line-item breakdown that maps directly to the SOV, showing the percentage of each work category completed during the billing period.³

Supporting documentation rounds out the package: invoices for stored materials, daily field reports, and photographs of the work in place. For materials stored off-site, common with custom-fabricated items that aren’t ready to install, the documentation burden is heavier. You’ll generally need the supplier’s invoice, proof of payment, photographs of the materials and their storage location, proof of insurance covering the stored items, and sometimes a warehouse receipt confirming the materials are being held for the project.

Once the package is complete, the contractor submits it to the architect or engineer serving as the certifying authority. The architect inspects the site, compares the claimed percentages against observable progress, and verifies that the work meets quality standards. If everything checks out, the architect signs the G702, certifying the payment amount. That certification turns the contractor’s request into a verified obligation for the owner.²

Why Applications Get Rejected

A rejected application doesn’t just delay one check. It pushes the entire billing cycle back, and that cascades down to every subcontractor and supplier waiting to get paid. The most frequent rejection triggers are avoidable with careful preparation:

Wrong billing form. Some general contractors require their own custom forms rather than standard AIA documents, and submitting the wrong one gets the application kicked back before anyone reviews the numbers.
Missing lien waivers from the prior payment period.
Billing for work covered by a change order that hasn’t been formally approved.
Insufficient proof of stored materials, such as missing warehouse receipts, insurance, or photographs.
Missed billing deadline. Each project has a specific submission window, and late applications usually wait until the next cycle.
Expired compliance documents, including lapsed insurance certificates, expired licenses, or missing safety certifications.

Retainage

Retainage is the portion of each progress payment the owner holds back as a security deposit. The withheld amount is typically between 5% and 10% of each payment. Many states cap retainage by statute, and those caps are roughly split between states setting a 5% maximum and those allowing up to 10%.

The holdback does two things. It motivates the contractor to push through to final completion, because the accumulated retainage can be significant on a large project and the contractor doesn’t collect it until the job is truly done. It also creates a reserve the owner can tap if defective work needs correction or outstanding claims from subs and suppliers surface.

Retainage is usually released in stages tied to specific project milestones. The first release typically happens at substantial completion, the point when the project is functional and usable for its intended purpose even though minor punch list items remain. That first release often covers the bulk of the withheld amount. The remainder is released at final completion, once every punch list item is resolved, closeout documentation is submitted, and final inspections pass.⁴

Lien Waivers

Every progress payment typically comes with a lien waiver, a document in which the party receiving payment gives up the right to file a mechanic’s lien against the property for the dollar amount covered by that payment. Owners and lenders require these because an unresolved mechanic’s lien clouds the property title and can block a sale or refinancing.

Waivers come in four basic varieties along two axes. The first is timing: a conditional waiver takes effect only once the payment actually clears, while an unconditional waiver takes effect immediately upon signing. The second is scope: a partial waiver covers only the current payment period, while a final waiver covers all work performed on the project. The conditional-versus-unconditional distinction matters more than most people realize. Signing an unconditional waiver before confirming the check has cleared means you’ve surrendered your lien rights even if the payment bounces.

Most states have specific statutory forms for lien waivers, and a handful require notarization. If the general contractor provides a custom form rather than the standard statutory version, read it carefully. Some custom forms include broad release language that waives not just lien rights but other contract claims as well.

How Payments Flow Down to Subcontractors

Progress payments don’t stop with the general contractor. After the GC receives payment from the owner, funds have to flow down to subcontractors, and from subcontractors down to their suppliers and lower-tier subs. How quickly that happens, and whether it happens at all, depends on the subcontract’s payment clause.

A “pay-when-paid” clause sets the timing of the subcontractor’s payment. The GC pays the sub within a reasonable time after receiving payment from the owner. If the owner is slow, the sub waits longer. But the GC is still obligated to pay eventually, regardless of whether the owner ever pays. The clause only controls when, not whether.

A “pay-if-paid” clause is far more aggressive. It makes the owner’s payment a true condition of the GC’s obligation. If the owner doesn’t pay the GC, the GC doesn’t owe the sub anything. The entire risk of owner nonpayment shifts onto the subcontractor, who has no contract with the owner and limited ability to influence whether the owner pays. Courts generally disfavor this arrangement. If the contract language isn’t explicit about making owner payment a condition precedent to the GC’s obligation, most courts will interpret the clause as pay-when-paid and hold the GC responsible. For a subcontractor reviewing a contract, this is one of the first clauses to scrutinize.

Prompt Payment Deadlines Under Federal and State Law

Both federal and state law impose deadlines on construction payments that override whatever the contract says. On federal construction projects, the government must pay a proper progress payment request within 14 days of receipt. If payment runs late, the government owes interest computed under Office of Management and Budget regulations. For retained amounts, the due date is either the date specified in the contract or, if none is specified, 30 days after the contracting officer approves the release.⁵

Nearly every state has its own prompt payment act, and most apply to both public and private construction. State deadlines for paying subcontractors after the higher-tier party receives its own payment tend to be short, generally 7 to 14 days. Penalties for late payment usually include statutory interest and, in some states, attorney’s fees. A contract that gives the owner 90 days to pay may be unenforceable if state law mandates a shorter deadline, so check local requirements before signing.

When a Progress Payment Is Wrongfully Withheld

If you’ve submitted a proper payment application and the owner or GC won’t pay, you have more leverage than you might think, but you need to act fast because the deadlines for most remedies are strict.

Under AIA A201, the most widely used general conditions document in U.S. construction, the contractor can stop work if the architect fails to certify a payment within seven days of receiving the application (through no fault of the contractor), or if the owner doesn’t pay within seven days of the date established in the contract. The contractor must give seven additional days’ written notice before stopping, but after that, the tools are down until the money arrives. Contractors can’t finance someone else’s building indefinitely, and the contract explicitly authorizes stopping work for that reason.

A contractor or subcontractor can also file a mechanic’s lien against the property. A mechanic’s lien encumbers the title and can prevent the owner from selling or refinancing until the debt is resolved. Filing deadlines and notice requirements vary by state, but they’re typically tight, often 60 to 90 days after the last work performed, and missing the deadline forfeits the right entirely.

On bonded projects, subcontractors and suppliers have an additional remedy. Federal law requires a payment bond on all federal construction contracts exceeding $100,000, and most states impose similar requirements on public projects.⁶ If you haven’t been paid in full within 90 days after your last day of work on a federal project, you can bring a claim against the payment bond. A subcontractor who worked under another subcontractor rather than directly under the GC must also give written notice to the GC within that same 90-day window. The lawsuit itself must be filed within one year of the last day of work or material delivery.⁷
