Every subcontractor has been there: you win a job, mobilize your crew, start pulling materials, and then reality sets in. The first pay app won’t be submitted for four to six weeks. Even after approval, net-30 or net-45 terms push actual payment out another month or more. Add retainage on top, and you could be three months into a project before a single dollar lands in your account.

By then, you’ve already absorbed the cost.

The contractors who manage this well aren’t the ones with the most cash; they’re the ones who ask the right questions before the project starts. Here are five questions every subcontractor should answer before signing a contract on a new job.

Not when your pay app is due. Not when it’s approved. When will it hit your bank account?

Map it out from day one:

• ■ Mobilization date
• ■ First pay app submission window
• ■ GC’s approval timeline
• ■ Pay terms (net-30, net-45, pay-when-paid)
• ■ Your bank’s ACH processing time

If you can’t answer this question clearly before you mobilize, you’re carrying more risk than you realize.

Working capital is the difference between your current assets and your current liabilities. It’s what keeps you operational between payments. And on a growing project, it gets consumed faster than most subcontractors expect.

The instinct is to reach for the bank line of credit when cash gets tight. But here’s the problem: your line of credit isn’t just a cash reserve. It’s a signal to bonding companies, surety agents, and GCs evaluating your pre-qualification. Heavy utilization or a line that’s frequently drawn down can quietly hurt your bonding rate and raise flags on future bids.

The question isn’t just can you tap the line. It’s should you use it for day-to-day cash gaps, or should it stay clean and available for growth?

Well-run subcontractors treat their bank line like a strategic reserve, not a recurring cash flow tool. That means having another option ready for the gaps that will predictably come on every project.

Not all billing cycles are equal. Pay app number one — covering the first month of work — is almost always the riskiest from a cash flow standpoint. You’ve mobilized, you’ve spent on labor and materials, and you’re waiting for a payment cycle that hasn’t turned yet.

Before the project starts, model your expected monthly billing and identify the windows when outflows exceed inflows. Payroll continues weekly regardless of where you are in the billing cycle. Material purchases often front-load the job. If your GC pays on a 45-day cycle, you may have two or three pay apps outstanding before you’ve collected a single one.

Retainage is one of the most significant — and most overlooked — working capital levers in a subcontract. Most GCs default to 10%. Many will accept 5% if you simply ask. And if you’re an early-scope trade who completes your work before the project reaches substantial completion, you may be able to negotiate a retainage reduction at the 50% milestone.

None of this is guaranteed. But the ask costs nothing, and the upside is thousands — or tens of thousands — in what would have been otherwise inaccessible cash, depending on your contract size.

Before you sign, push on three things:

• ■ Retainage rate: Can you get to 5%?
• ■ Retainage reduction clause: Does your contract include language to reduce retainage to 50% upon project completion?
• ■ Retainage release timing: How quickly will retainage be released after your scope is complete, even if the overall project isn’t?

The worst time to explore financing options is when you’re already in a cash crunch. At that point, your options narrow, the urgency signals risk to lenders, and you’re making decisions under pressure instead of from a position of control.

For subcontractors looking for an option that doesn’t require notifying their GC, doesn’t create debt on the balance sheet, and doesn’t touch the bank line, there are now purpose-built solutions for exactly this situation. Quick Pay Direct by ProNovos, funded by Viva Capital, is one of them.

Here’s how it works:

This is spot factoring. You choose which invoices to fund, on which projects, and at which times. You’re not locked into a blanket arrangement. And because it’s structured as a receivable purchase rather than a loan, it doesn’t create debt on your balance sheet or touch your credit.

The Bottom Line

Cash flow problems in construction are rarely unpredictable — they’re just unplanned for. Every project has a first-pay app gap, a retainage pool, and a set of weeks in which outflows exceed inflows. The contractors who navigate this best are the ones who see it coming.

Ask these five questions before you sign. Map the gap. Negotiate your retainage terms. And have a working capital tool in place before you need to pull the lever.
