A general contractor payment schedule defines when, how, and how much a GC gets paid throughout a construction project. It is the financial backbone of every job. Get it wrong and you carry costs out of pocket for months. Get it right and your cash flow matches your expenditures.

On a $10 million commercial project, a poorly structured payment schedule can force a GC to carry $500,000 to $1 million in unreimbursed costs at any given time. That is working capital tied up in one project instead of funding the next one.

This guide covers every element of the general contractor payment schedule from contract negotiation through final payment.

How a General Contractor Payment Schedule Works

The payment schedule establishes the rhythm of billing and payment on a construction project. Most commercial construction projects use monthly progress billing, where the GC submits a pay application each month for the work completed during that period.

The typical cycle runs like this:

Billing cutoff date -- The last day of the billing period (often the 25th of the month)
Pay application submission -- The GC submits the application within 3-5 days of cutoff
Review period -- The owner/architect reviews the application (7-14 days)
Certification -- The architect certifies the amount due
Payment -- The owner pays the certified amount (typically within 30 days of submission)

From work performed to cash received, the cycle runs 30-60 days. This gap is the GC's financing obligation.

Components of a Payment Schedule

Every general contractor payment schedule includes these components.

The Schedule of Values (SOV)

The SOV breaks the total contract into line items that correspond to elements of the work. Each line item has a dollar value. Monthly billing is based on the percentage of each line item completed during the billing period.

A well-structured SOV has 20-40 line items that align with the project schedule. Too few line items and billing becomes imprecise. Too many and the monthly review process becomes unwieldy.

Retainage

Retainage is the percentage of each payment that the owner withholds until project completion. Standard retainage runs 5-10% depending on the state and the contract.

On a $10 million contract with 10% retainage, the owner holds $1 million from the GC's payments throughout the project. This money is released at substantial completion (or later, depending on the contract).

Progress Payments

Progress payments are the monthly amounts the GC receives based on the certified pay application. The formula is:

Gross billing (work completed + stored materials) minus retainage minus previous payments = current progress payment.

Final Payment

Final payment includes the release of retainage and payment for any remaining work. Final payment is typically conditioned on:

Substantial completion
Punch list completion
Receipt of all close-out documents (warranties, O&M manuals, as-builts)
Consent of surety (if bonded)
Release of liens from all subcontractors and suppliers

Payment Schedule by Project Type

Different project types follow different payment structures.

Project Type	Typical Billing Cycle	Retainage	Payment Terms	Special Conditions
Private Commercial	Monthly	10% (5% after 50%)	Net 30 from submission	Negotiable
Public (State/Local)	Monthly	5-10% (statutory)	Per prompt payment act	Prevailing wage verification
Federal	Monthly	5-10%	Net 14 from approval	FAR compliance required
Residential Custom	Draw schedule (milestones)	Varies	At milestone completion	Lender approval required
Design-Build	Monthly or milestone	5-10%	Per contract	Tied to design phase completion

Negotiating the Payment Schedule

The payment schedule is negotiable on private projects. These are the terms worth fighting for.

Billing frequency. Monthly is standard, but bi-weekly billing reduces your financing gap. On a $10 million project, bi-weekly billing cuts your average unbilled work-in-progress by approximately 50%.

Review period. Push for a 7-day review period instead of 14. Every day of review delay is a day you carry unreimbursed costs. The AIA A201 standard is 7 days for certification after receipt.

Payment terms. Net 30 from submission is standard. Net 15 or Net 20 improves your cash position. On public projects, prompt payment acts often mandate 7-day payment after certification.

Retainage reduction. Negotiate retainage reduction to 5% (or lower) after the project reaches 50% completion. Many contracts allow this. Some state statutes mandate it.

Stored materials billing. Ensure the contract allows billing for materials stored on-site and off-site. This lets you recover material costs before installation, improving cash flow during procurement-heavy phases.

Building a Payment Schedule That Protects Cash Flow

Cash flow problems on construction projects almost always trace back to the payment schedule structure.

Align the SOV with your cost schedule. If you spend heavily on structural work in months 3-6, your SOV should reflect that spending pattern. Front-loading the SOV (putting higher values on early line items) accelerates your billing, but over-doing it creates retainage release problems at close-out.

Bill stored materials aggressively. When you purchase $200,000 in curtain wall materials in month 4 but do not install them until month 7, bill the stored materials in month 4. This closes the cash flow gap between procurement and installation.

Submit pay applications on time, every time. Late submissions delay the entire payment cycle. If your billing cutoff is the 25th and your submission is due on the 28th, have the pay application ready on the 27th. One late submission can push payment back an entire month.

Track subcontractor billing against your billing. Your subcontractors submit pay applications to you. You include their work in your pay application to the owner. If you pay subs before you collect from the owner, you are financing the owner's project with your working capital.

Subcontractor Payment Schedule Management

The GC's payment schedule creates a cascade. The owner pays the GC. The GC pays the subcontractors. The subcontractors pay their suppliers.

Pay-when-paid clauses tie the GC's obligation to pay subs to receipt of payment from the owner. These clauses are enforceable in most states but create financial strain on subcontractors.

Pay-if-paid clauses condition the GC's payment obligation on actual receipt from the owner. These are more restrictive and unenforceable in several states including California, New York, and North Carolina.

Prompt payment obligations require the GC to pay subcontractors within a statutory timeframe after receiving payment. Most states mandate payment within 7-10 days. Penalties for late payment include interest charges and potential attorney's fee exposure.

Payment Clause Type	GC's Obligation	Enforceable?	Risk to Sub
Pay-when-paid	Pay within reasonable time after receipt	Most states yes	Moderate delay risk
Pay-if-paid	Pay only if owner pays	Several states no	High non-payment risk
Prompt payment (statutory)	Pay within 7-10 days of receipt	Yes (state law)	Low risk

Common Payment Schedule Problems

Problem 1: Billing cutoff misalignment. The GC's billing cutoff does not match the subcontractors' billing cutoffs. Result: the GC includes incomplete subcontractor billing in their pay application, leaving money un-billed for a month.

Problem 2: Retainage tracking errors. The GC's retainage calculation does not match the owner's. The discrepancy compounds monthly and creates a reconciliation nightmare at close-out.

Problem 3: Change order billing delays. Approved change orders are not added to the SOV in the month they are executed. The GC delays billing for work already completed and approved.

Problem 4: Final payment disputes. The contract requires conditions for final payment that take months to satisfy (close-out documents, lien releases). The GC carries the retainage balance and final billing until all conditions are met.

Frequently Asked Questions

What is a typical general contractor payment schedule on a 12-month commercial project?

Monthly progress payments based on the percentage of work completed during each billing period. Retainage of 10% is held for the first half of the project, reduced to 5% at 50% completion. Final payment (retainage release) occurs 30-60 days after substantial completion, conditioned on close-out document delivery.

How does the payment schedule change on a cost-plus contract?

Cost-plus contracts bill actual costs plus a fee. The payment schedule still follows a monthly cycle, but the billing is based on documented costs (labor, material, equipment, subcontractor invoices) rather than percentage completion of SOV line items. The fee may be billed as a percentage of costs or as a lump sum prorated over the project duration.

Can a GC charge interest on late owner payments?

The contract determines whether interest accrues on late payments. AIA A201 provides for interest at the rate prevailing at the place of the project. On public projects, state prompt payment acts specify the interest rate for late payment, which ranges from 1% to 2% per month depending on the state.

How should a GC handle a payment schedule on a fast-tracked project?

Fast-tracked projects benefit from bi-weekly or accelerated billing cycles because work progresses faster and costs accumulate more quickly. The SOV should be structured with more granular line items to capture the overlapping work phases. Stored materials billing is especially important when procurement runs ahead of installation.

What is the GC's obligation if the owner fails to pay?

The GC's options include filing a mechanic's lien (on private projects), making a claim on the payment bond (on public projects), suspending work after proper notice, and pursuing breach of contract claims. The specific rights depend on the contract terms and applicable state law.

How does retainage release work at the end of the project?

Retainage release is typically triggered by substantial completion. The owner may release 50% of retainage at substantial completion and hold the remainder until final completion (punch list, close-out documents, final lien releases). Some contracts release retainage in a single payment after all close-out conditions are satisfied.
