The Construction Cash Flow Cycle

Construction has a brutal cash timing: you pay first and get paid last.

The cycle

1. You spend — labor weekly, materials on delivery, mobilization up front.
2. You bill — usually monthly, for work already done.
3. You collect — often 30–60+ days after billing.
4. Retainage — a slice (5–10%) is held back until the very end.

The gap between spending and collecting is where the cash crunch lives — and retainage means part of your profit is locked up until closeout.

Going Deeper (Intermediate)

The construction cash cycle is brutal by design:

1. You pay labor weekly and buy materials up front.
2. You bill monthly (in arrears) for work already done.
3. The owner pays 30–60+ days after that.
4. Retainage is held until the job finishes — sometimes months later.

The gap between cash out and cash in is the "cash trough" every job digs before it climbs back out.

Advanced / Pro-Level

Managing the trough:

• Quantify the gap in days and dollars per job, then make sure you have working capital or a line of credit to cover the deepest point of all jobs combined.
• Shrink the gap: negotiate deposits/mobilization, faster draw cycles, stored-material billing, and retainage reduction.
• The cardinal sin: funding Job B's costs with Job A's deposit ("robbing Peter to pay Paul"). It works until one job slips and the whole house of cards falls — a leading cause of contractor failure.

Practice Challenge

You pay $40k/week in labor, bill monthly, and get paid 45 days after billing. Roughly how long is your cash outlaid before the first payment returns? (Answer: ~75 days (up to a month of work performed + ~45 days to collect) — you must fund ~10+ weeks of costs, before retainage, from working capital or a credit line.)

In Practice

You pay the crew weekly and buy materials on delivery, but the owner pays 45 days after you bill — and holds retainage. That gap is the cash crunch; plan for it.

Common Mistakes to Avoid

• Not planning for the pay-first-collect-later gap
• Forgetting retainage ties up your profit
• Underestimating mobilization costs

Takeaway: You pay first and get paid last — plan for the gap between spending and collecting.
