CASH FLOW CYCLE

SUBCONTRACT FINANCIAL TERMS, DEFINED.

QUICK ANSWER

The contract terms that decide when a subcontractor gets paid include retainage, pay-when-paid versus pay-if-paid, the schedule of values, the pay application, lien waivers, and backcharges. Each one moves cash timing, and misreading any of them is how a profitable job turns into a cash problem. Plain-language definitions are below.

Most subcontractors learn these terms the expensive way, after a pay-if-paid clause leaves them holding a loss or a backcharge eats a job's margin. Buried in the language is everything that decides how fast you bill, how much gets held back, what you have to sign before a check moves, and who can charge what against your work. The definitions below are grouped by the part of the cash cycle each term touches, so you can read a subcontract for what it does to your money rather than for what it says about scope.

THE DEFINITION

WHAT IT MEANS.

A subcontract is a cash flow document before it's anything else: the financial terms inside it decide how fast you bill, how much gets held back, what you have to sign to get paid, and who can charge what against your work.

Billing and collection, how and when you bill. The schedule of values divides your contract price into line items you bill against as work completes. A pay application is the formal request for payment, submitted on the GC's schedule, showing work completed against the SOV. Time-and-material work is billed at actual labor and material plus a markup, instead of a fixed price.

Holdbacks and payment risk, what gets held and who pays. Retainage, also called retention, is a percentage of each payment, often 5% to 10%, that the GC holds until the job is complete. Pay-when-paid means the GC pays you within a reasonable time after the owner pays them, so the risk is timing. Pay-if-paid means the GC only pays you if the owner pays them, so the risk is the entire loss. Liquidated damages are a pre-agreed dollar amount charged per day of delay you cause.

Changes and charges, what moves the contract value. A change order is a written modification to the contract value for work added or changed. A backcharge is a deduction the GC or another trade applies to your payment for cost they claim your work caused, whether cleanup, damage, or delay. A lien waiver is a document releasing your right to file a mechanic's lien for the amount paid.

WHERE THE MONEY GOES

WHAT THESE TERMS COST YOU.

01

Billing and collection: a back-loaded SOV starves the early months

A flat or back-loaded schedule of values starves the early months, when your costs are highest, because the billing curve sits behind the cost curve for the whole first half of the job. T&M billed monthly instead of within 48 hours creates permanent uncollected float, since the cost goes out now and the bill goes in weeks later. Both are structural, and both get decided before the first crew reaches the site.

02

Holdbacks and payment risk: retention gets forgotten and pay-if-paid gets signed

Forgotten retention is the most common uncollected cash a subcontractor is owed, because it's money you earned that nobody tracks as its own receivable. Pay-if-paid moves the owner's nonpayment onto you, and it's the single most dangerous clause in a subcontract. Liquidated damages sit alongside both of those, priced per day, in language most subs read once and never model against a real schedule.

03

Changes and charges: unsigned work and unchallenged deductions

Work built without a signed change order is work you gave away, and the conversation about it gets harder every week that passes. An undocumented or disputed backcharge can take margin off a job without anybody deciding to let it. Signing an unconditional waiver before the check clears can leave you with no claim and no payment, which is the worst of both outcomes.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

The two figures to hold onto

Retainage is often 5% to 10% of each payment, held until the job is complete, and it belongs in your books as its own receivable rather than buried inside general AR. T&M tickets should be billed within 48 hours of the work rather than at the end of the month, because every day between the cost going out and the bill going in is float you're financing yourself.

COMMON QUESTIONS

FREQUENTLY ASKED.

Pay-when-paid means the GC pays you within a reasonable time after the owner pays them, so the risk is timing. Pay-if-paid means the GC pays you only if the owner pays them, moving the entire risk of the owner's nonpayment onto you. Pay-if-paid is the most dangerous clause in a subcontract.
Retainage, also called retention, is a percentage of each payment, often 5% to 10%, that the general contractor holds back until the job is complete. It's money you earned but can't collect yet, and it should be tracked as its own receivable. Forgotten retention is the most common uncollected cash a subcontractor is owed.
A schedule of values divides your contract price into billable line items you bill against as work completes. How you structure it decides cash timing: front-loading mobilization and early phases, within reason, brings cash in sooner, while a back-loaded SOV starves the early months when costs are highest.
A backcharge is a deduction the GC or another trade applies to your payment for cost they claim your work caused, such as cleanup, damage, or delay. An undocumented or disputed backcharge takes margin off a job without anybody deciding to allow it, so it should be challenged in writing with evidence rather than absorbed.
Because the subcontract decides when and whether you get paid. Retainage, pay-if-paid clauses, the SOV structure, lien waivers, and liquidated damages each move cash, risk, or margin.
