A specialty subcontractor we recently worked with was dealing with a familiar construction cash flow problem. The company completed the work, paid crews and vendors, and then waited for the general contractor to receive payment before cash flowed downstream.
On paper, that looked like a simple payment term. Financially, it meant something bigger, because by accepting a pay-when-paid clause, the company was using its own working capital to fund the payment gap without being separately compensated for that financing.
We recommended putting a dollar value on that delay and making sure the pricing reflected it.
The same dynamic may be affecting your margins, and putting a dollar value on the delay can help you decide which payment terms your business can afford.
What Does a Pay-When-Paid Clause Mean for a Subcontractor?
A pay-when-paid clause generally ties the timing of a subcontractor’s payment to when the general contractor receives payment from the owner.
That’s different from a pay-if-paid provision, which may attempt to make owner payment a condition of whether the subcontractor gets paid at all. The exact effect and enforceability depend on state law and contract language, so legal counsel should review the terms on a specific project.
From a finance perspective, the concern is simpler, because when you perform the work today and receive the cash weeks or months later, your company has to fund the gap.
What Does Slow GC Payment Really Cost You?
The cost of slow payment often sits outside the job cost report.
If a subcontractor uses a line of credit to cover payroll, materials, or vendor bills while waiting on a GC, the interest expense may appear elsewhere on the income statement.
The project can look more profitable than it really is if the financing burden is never connected back to the payment terms that created it.
How Do You Calculate the Cost of Carrying a GC’s Receivable?
Start with the cash tied up, the additional days you expect to carry it, and your company’s cost of capital.
A practical way to estimate it looks like this:
Amount billed × annual cost of capital × additional days outstanding ÷ 365
Suppose you hold a $2 million subcontract, the GC pays each progress billing about 60 days later than standard terms, and your relevant financing cost is 9 percent annually.
$2,000,000 × 9% × 60 ÷ 365 = $29,589
You won’t have the full $2 million outstanding at once, but every dollar billed over the life of the project remains outstanding for an additional 60 days. On an eight-month project with relatively even billing, that’s economically equivalent to carrying roughly $500,000 of additional receivables for about eight months, which brings the total financing cost to approximately $29,589.
Should You Simply Add Your Interest Rate to the Job Price?
No. An annual financing rate and a pricing premium aren’t the same thing.
Using the example above, the $29,589 carrying cost equals roughly 1.5 percent of the $2 million contract value.
That gives the estimating team a specific, defensible starting point for a premium instead of a round-number guess. Management can then decide whether additional margin is appropriate for uncertainty around timing, administrative effort, or concentration with a particular GC.
What Can You Ask for Instead of Simply Accepting Longer Terms?
If a GC wants more flexibility on subcontractor payment terms, make that flexibility part of the commercial negotiation.
For this client, we recommended negotiating extended terms in exchange for a pricing premium. It changes the tone of the conversation, because instead of asking the GC whether they can pay faster, the subcontractor can show what slower payment costs and what price makes those terms work for both sides.
Depending on the project, other options may include shorter payment terms, different billing milestones, a mobilization payment where appropriate, or another structure that reduces how much capital remains tied up.
Which GCs Are Using the Most of Your Working Capital?
Companywide accounts receivable can hide large differences between customers.
One GC may routinely pay close to agreed terms, while another adds several weeks to every payment cycle. If both relationships are blended into one DSO number, the slower customer can look less expensive than it is.
We review four items for each major GC:
- Contract terms: How many days you agreed to carry the receivable
- Actual payment days: How long the GC typically takes to pay
- Average receivable balance: How much cash is routinely tied up
- Financing cost: What the additional carrying period costs your business
Looking at DSO by major customers turns a reporting metric into a pricing and account management tool. It shows where working capital is being consumed and which relationships may deserve different terms.
How Do Pay-When-Paid Terms Fit Into Your Broader Construction Cash Flow Strategy?
Negotiating GC payment terms is one lever among several, and it works best alongside the rest of your cash strategy.
How quickly you bill and collect, how deliberately you use vendor terms, and how accurately you forecast project cash needs can all change the amount of working capital tied up in operations.
That side of the equation can matter as much as the GC negotiation, as we showed in our breakdown of how a few days of DSO and DPO freed up $600,000 for a contractor.
FAQs About Pay-When-Paid Clauses
What happens if the owner never pays the general contractor?
It depends on the clause and state law. Under many pay-when-paid clauses, the GC may still have to pay within a reasonable time, while lien or payment bond rights may provide another recovery path.
Can a subcontractor charge interest on late payments?
Often, yes. State prompt payment laws may allow interest on late amounts, and the contract may include separate late payment terms.
Can I negotiate the pay-when-paid clause itself?
Yes. Options may include an outside payment date, joint checks, or separate retainage terms, depending on the project and applicable law.
Will adding a pricing premium make my bid less competitive?
It can. One approach is to offer pricing for standard terms and separate pricing for extended terms so the cost of slower payment is visible.
