5 Signs a GC Will Pay You Late (And What to Do)

Late payments are the number one cash flow killer for subcontractors. But here's the thing: you can usually see them coming. There are warning signs that tell you early enough to protect yourself, tighten cash flow, or stop work before you're owed thousands.

We've talked to hundreds of subs, and the ones who avoid disaster all have one thing in common: they read the signals. Let's walk through the five biggest red flags.

Sign #1: They're Slow Responding to Your Pay Applications

A GC that's having cash flow problems gets quiet. They don't return emails about pay apps quickly. When you follow up, they blame someone else—the owner, the lender, the architect. They start giving vague timelines instead of concrete dates.

This is often the first sign. A healthy GC processes pay apps fast and clearly. They're organized because their finances are organized. If responses slow down or become evasive, it's time to get serious.

What to Do Now

• Start documenting the exact dates you submit pay apps and when you receive responses
• Put follow-ups in writing via email with read receipts
• Ask for a specific payment date, not just "soon"
• Request a meeting to discuss payment schedules

Sign #2: The Owner or Lender Hasn't Released Funds Yet (That You Know Of)

The best source of information is the owner or their representative. If you can figure out whether the owner has released funding to the GC, you know whether they can pay you. Many subs don't ask because they assume it's none of their business. It is.

If the owner is withholding funds or has withheld them before, that's a red flag. If the lender is slow with draws, that's a red flag. These delays cascade down to you.

What to Do Now

• Ask the GC directly: "When do you expect the draw payment from the owner?"
• If they're evasive, ask a more direct question: "Has the owner released payment yet?"
• On larger jobs, connect with the owner's rep directly and ask about payment schedules
• Check with other subs on the job—they know what's happening

Sign #3: They're Requesting Extended Payment Terms

A GC that's healthy pays on time because they've been paid. One that's not healthy asks for extended payment terms. They might say, "Can we push payment to net-45 instead of net-30?" or "Can you wait 10 extra days on this invoice?"

When the GC starts negotiating payment terms downward, they're managing cash flow, not yours. This is a sign they're short on money.

What to Do Now

• Don't agree to extended terms unless your contract allows it
• If you do agree, add specific payment dates in writing
• Tighten retainage—ask for higher paid percentages and lower retention
• Consider front-loading your invoicing so you get paid earlier for earlier work

Sign #4: They're Taking on New Subcontractors for the Same Work

You're the electrical sub. Suddenly, they hire a second electrical sub for "additional work" that could easily go to you. Or they bring in a general labor sub to do work that's normally your responsibility at a higher markup.

This usually means one of two things: they're bringing in another sub because you won't front money anymore, or they're trying to squeeze margin by substituting cheaper labor. Either way, it's a sign of problems.

The more reliable indicator is when they bring in subs to do work that should be yours, especially if it's work you've been bidding on. That's them shopping for better terms—and it means they're desperate enough to create inefficiencies.

What to Do Now

• Ask directly why they're bringing in another sub
• If it's for additional work, ask why they didn't expand your contract
• Document your conversation
• If patterns emerge, prepare to limit your exposure or stop new work on this GC

Sign #5: Their Other Subs Are Complaining About Payment

You talk to other subs on the job. One says they're 30 days late on a bill. Another mentions they had to stop work last week waiting for payment. A third tells you they're considering filing a lien.

This is the most reliable indicator. If multiple subs are having payment problems with the same GC, it's a systemic issue. It's not miscommunication or a one-time delay. It's a cash flow crisis affecting the whole project.

What to Do Now

• Coordinate with other subs if possible—collective pressure gets attention
• Document all conversations about payment delays
• Send a formal demand for payment in writing
• Review your lien rights and deadlines immediately
• Consider holding work if you're comfortable doing so and your contract allows it
• Prepare to file a lien if payment doesn't come within your state's deadline

The Escalation Plan

If you see any of these signs, follow this sequence:

1. Week 1-2: Document everything. Track payment dates, communication delays, and conversations with other subs.
2. Week 3: Have a direct conversation with the GC about payment. Get a specific date in writing.
3. Week 4: If payment doesn't arrive on that date, send a formal payment demand via email.
4. Week 5: If still unpaid, file a preliminary lien notice (if required in your state).
5. Week 6: Consult a construction attorney if you're close to your lien filing deadline.
6. Before deadline: File the actual lien if payment hasn't been received.

What NOT to Do

While you're managing the risk, avoid these mistakes:

• Don't keep quiet. Hoping it works out is how you end up with a $50K debt 6 months later.
• Don't work without getting paid. If they're already late, don't keep fronting labor and materials.
• Don't sign documents you don't understand. Waivers, change orders, and amended contracts are tools they'll use to reset your position.
• Don't miss lien deadlines. Nothing you do after the deadline matters. Your right to lien expires, period.

The Bottom Line

Late payments aren't random. They follow patterns. The GCs who pay late usually show signs first—slow responses, cash flow language, requests for extended terms, and complaints from other subs. If you see these signs, act immediately. Document everything, communicate in writing, and prepare to protect your lien rights.

The subs who avoid late payment disasters are the ones who read the signals early and respond decisively. Be that sub.
