Billing and cash flow

Which construction payment terms should contractors negotiate?

Negotiate when you get paid, what can stop payment, how much is held back, and what happens when payment is late. Those four areas decide your cash flow more than the contract price does.

The payment terms worth negotiating in any construction contract are: how many days after billing (or after the GC is paid) you get paid, whether payment is conditioned on the owner paying (pay-if-paid or pay-when-paid), the retainage rate and release trigger, interest on late payments, your right to stop work if unpaid, how change orders get paid, and what closeout documents are required for final payment. Get these right and a decent price turns into actual cash. Get them wrong and a great price can still break your cash flow.

Contractors often spend days on scope and price, then sign the payment section without reading it. That section is where the money is.

The payment terms that matter most

1. Payment timing

Look for a fixed number of days for payment after a proper pay application, or after the GC receives owner payment. Federal work sets a benchmark: under the FAR prompt payment clause for construction, progress payments are due 14 days after the government's billing office receives a proper payment request, and primes must pay subs no later than 7 days after they receive payment. Private contracts can say anything, so negotiate a specific number of days and an outside date.

2. Pay-if-paid vs pay-when-paid

A pay-if-paid clause can make owner payment a condition of your payment, shifting the owner's credit risk to you. A pay-when-paid clause is usually read as a timing rule: payment waits a reasonable time for owner payment but is still owed. Push for pay-when-paid with an outside date. Some states limit pay-if-paid clauses, so check your state. Read pay-if-paid vs pay-when-paid clauses explained.

3. Retainage rate, reduction, and release

Negotiate the rate, a reduction at a milestone (for example, at 50 percent complete), and release when your scope is complete and accepted rather than when the whole project closes. For comparison, the FAR clause for fixed-price construction allows a contracting officer to retain a maximum of 10 percent of a payment until satisfactory progress is achieved. Many states cap retainage on public work and some on private work. See prompt payment and retainage laws by state.

4. Interest on late payment

Ask for interest on any amount not paid by the due date. Many state prompt payment laws already provide it, but writing it into the contract removes debate.

5. Right to stop work or suspend

Negotiate a right to stop work after a stated number of days of nonpayment and written notice, with schedule time and remobilization costs added. Without it, stopping work can put you in breach.

6. Withholding and back-charge notice

Require written notice of any withholding or back-charge, with the amount and reason, within a set time, and a chance to cure. This prevents surprise deductions. Federal construction already requires this kind of written withholding notice from primes to subs.

7. Change order payment

Set how quickly approved changes can be billed, what markup applies, and how disputed changes get paid while being resolved. Insist that directed work can be billed even if pricing is still in negotiation.

8. Stored materials and deposits

If you order long-lead equipment, negotiate the right to bill stored materials, including off-site storage with clear backup rules. On residential work, set deposits within your state's limits.

9. Closeout and final payment

List exactly which documents trigger final payment (warranties, as-builts, waivers, O&M manuals) and the number of days after submission that payment is due. Vague closeout terms are how retainage gets held for a year.

Worked example: negotiating a $520,000 subcontract

Say a concrete sub is handed a $520,000 subcontract with pay-if-paid language, 10 percent retainage released "upon final completion of the project," and no stop-work right. The owner's prime contract holds 5 percent from the GC.

The sub asks for three changes and gets two. Retainage drops to 5 percent to match the owner's rate, and release is tied to acceptance of the concrete scope, which finishes about eight months before the project does. Pay-if-paid becomes pay-when-paid with a 45-day outside date. The GC refuses a stop-work clause, so the sub prices a little extra contingency into its next bid with that GC.

The retainage change alone cuts the money held from $52,000 to $26,000 on the full contract value, and gets it released eight months sooner. That is the kind of result a careful payment section produces without touching the price.

How to ask without losing the job

Contractors worry that pushing back on payment terms will cost them the work. Usually it does not, if you ask the right way. Send your requested changes as a short, specific list rather than a marked-up 40-page document. Explain the reason in business terms: matching retainage to the owner's rate is fair, and an outside payment date is standard risk sharing. Offer trades where you can, such as accepting a longer payment window in exchange for interest on late payment. And ask early, ideally with your bid, so the terms are part of the price conversation.

Mistakes to avoid

  1. Negotiating price for hours and signing the payment section unread.
  2. Accepting retainage higher than the owner holds from the GC.
  3. Agreeing to vague triggers like "upon owner acceptance" with no date.
  4. Assuming state prompt payment law covers you without checking whether it applies to private work.
  5. Ignoring flow-down clauses that import the owner's payment terms. See flow-down clauses explained for subcontractors.
  6. Asking for everything. Pick the two or three terms that matter most on this job.

Frequently asked questions

What is a fair payment term in a construction subcontract?

There is no single standard. A fixed number of days after the GC is paid, with an outside date regardless of owner payment, is a common target. Federal work requires primes to pay subs within 7 days of receiving payment.

Can I negotiate retainage as a subcontractor?

Yes. Common asks are a rate no higher than what the owner holds from the GC, a reduction at a milestone, and release when your scope is accepted.

Are pay-if-paid clauses enforceable?

It depends on the state. Some enforce them as written, some interpret them narrowly, and some limit them by statute. Check your state and negotiate pay-when-paid language where you can.

Should I walk away from bad payment terms?

Sometimes. If the terms leave you financing the job with no protection, price the risk in or pass. Track how each GC actually pays so the decision is based on history, not hope.
