The construction payment chain is the sequence of payments from lender to owner to general contractor to subcontractor to supplier, and each link adds delay and risk. Subcontractors report waiting an average of 51 days to be paid after submitting a pay application, so how you structure the schedule of values and manage retainage shapes your cash flow.
From lender to owner to GC to subcontractor to supplier. Each link adds delay and risk. Understanding the chain is essential for protecting your cash flow.
Average time subcontractors report waiting to be paid after submitting a pay application. General contractors in the same survey estimate they send payment in 35 days.

The schedule of values (SOV) is a detailed breakdown of the contract sum into individual line items, each representing a portion of the work. How you structure it determines your cash flow for the entire project duration.
A detailed breakdown of the contract sum into individual line items, each representing a portion of the work. Submitted at project start and approved by the architect. Each month, you report percent complete on each line item to calculate the payment due.
Allocating more value to early-phase work (mobilization, site prep, foundations) improves early cash flow. Legitimate front-loading includes properly valuing preconstruction effort and overhead-heavy early phases. A well-structured SOV can improve cash position in the first quarter.
You can bill for materials purchased and stored (on-site or off-site) before installation. Requires proof of purchase, insurance coverage, and proper storage. Off-site storage needs a bill of sale and evidence the materials are specifically allocated to your project.
Approved change orders are added to the SOV as new line items. The challenge: billing for CO work performed before formal approval. Best practice is to document directed changes in writing and bill monthly even if the formal CO is not yet executed.
The AIA G702 is the cover sheet that summarizes the total payment request, and the G703 is the continuation sheet (the schedule of values) that breaks it down line by line. These two AIA forms are the backbone of commercial construction billing. Understanding every field is critical for accurate, timely pay apps.
The cover sheet summarizing the total payment request. Six key fields drive the math.
The initial agreed contract amount before any changes.
Total of all approved change orders (additions minus deductions).
Cumulative value of all work performed and materials stored to date.
Total amount withheld (typically 5–10% of completed work).
This period's billing minus retainage, minus any prior overpayments.
Remaining contract value including retainage held to date.
The detailed line-by-line breakdown attached to the G702. Each row contains item number, description, scheduled value, previous applications, this period, materials stored, total completed, % complete, balance to finish, and retainage.
Retainage is a 5–10% share of every payment that is withheld until release. Most commercial contracts withhold 10% until 50% completion, then reduce to 5%, and release it at substantial completion, though punch list holdbacks may continue. On a $10M project, that is $500K–$1M of your working capital trapped for the project duration. Managing retainage well is a major cash lever.
Most commercial contracts withhold 10% until 50% completion, then reduce to 5%. Some owners maintain 10% throughout. Federal projects (Miller Act) typically hold 5% under prompt payment requirements. Retainage is released at substantial completion, though punch list holdbacks may continue.
Many states cap retainage: Texas at 10%, California at 5% on public work, New York at 5% on private work. Some require escrow with interest. Know your state's prompt payment act — it overrides contract language. Currently 48 states have some form of prompt payment statute.
Negotiate reduction to 5% at 50% completion. Request release at substantial completion rather than final completion. Ask for interest-bearing escrow. On a $50M contract, even 0.5% less retainage equals $250,000 of working capital.
GCs typically retain the same percentage from subs as the owner retains from them. When the owner releases, the GC should promptly release sub retainage. Many prompt payment acts require this within 7–14 days. Retaining more than the owner retains from you creates a cash float — but damages relationships.
Pay-when-paid is a timing mechanism: the GC pays the sub after receiving owner payment but still has an independent obligation to pay. Pay-if-paid is a condition precedent: the GC pays only if the owner pays, which shifts the owner's credit risk entirely to the subcontractor. They sound similar but the legal difference can mean the difference between getting paid and never getting paid.
If you see language like "receipt of payment from the Owner is a condition precedent to Contractor's obligation to make payment to Subcontractor," that is a pay-if-paid clause. Negotiate to change "condition precedent" to "timing mechanism" or add a reasonable payment deadline (e.g., 45 days) regardless of owner payment status. See the Contract Types Guide for negotiation strategies. Trueleveler's Contract Review engine flags pay-if-paid and pay-when-paid language automatically when it reads a subcontract, so the distinction surfaces before you sign — not after the owner stops paying.
Forecast monthly. Manage proactively. Four habits separate survivors from casualties.
Map out expected billing (from the SOV), expected collection (billing minus retainage, plus 30–45 day payment lag), and expected outflows (sub payments, material purchases, payroll, equipment). Update monthly with actuals. The gap between collection and outflow is your financing requirement.
Submit pay applications on time every month, without exception. A late or incomplete pay app costs you 30+ days of cash flow. Pre-populate the G703 weekly so monthly billing is a review exercise, not a scramble. Track percent complete daily on high-value line items.
With suppliers, negotiate net-45 or net-60 for materials. With the owner, push for 21-day payment cycles instead of 30. Early payment discounts (2/10 net 30) from suppliers can save 1–2% on material costs while improving your payment reputation.
Maintain a revolving line of credit sized at 10–15% of annual revenue. Draw to bridge payment gaps, not to fund operations. The cost of a line of credit (prime + 1–3%) is far less than the cost of late payments to vendors (damaged relationships, higher future pricing, lien exposure).
The six most common payment disputes are percent complete disagreements, unapproved change order work, back-charges, retainage release delays, lien waiver disputes and stored material disputes. These six patterns account for the vast majority of payment disputes. Prevention comes from documentation, not from lawyers.
The architect says 60%; the contractor says 80%. The most frequent pay app dispute. Use measurable milestones, date-stamped photos, and meet with the architect before submitting each pay app to align on progress.
Work performed under verbal direction but without a signed CO creates billing disputes. Confirm all changes in writing before performing. Bill under protest if you must proceed without approval.
The GC deducts costs from a sub's payment for alleged defects, cleanup, or damage — often without proper notice. Require written notice before any back-charge, document site conditions, and dispute unauthorized deductions in writing immediately.
After substantial completion, owners often delay retainage release citing punch list items worth far less than the retainage. A $500K retainage hold for a $15K punch list is disproportionate. Negotiate a holdback limited to 150% of punch list value.
Conditional vs. unconditional waivers create confusion. Never sign an unconditional waiver until payment clears your bank. Some owners demand unconditional waivers as a condition of receiving payment — this is improper and potentially illegal in statutory-waiver states.
Owner refuses to pay for stored materials citing insufficient documentation or segregation. Photograph all stored materials, maintain bills of lading, provide insurance certificates for off-site storage, and mark materials clearly with project identification.
