WHY PROFITABLE
CONTRACTORS
RUN OUT OF CASH.
Profitable subcontractors run out of cash because profit and cash are two different things. Revenue sits in unpaid invoices. Overhead runs whether work is billed or not. Equipment, labor, and materials are paid before the GC pays you. A $5M contractor can net 8% on paper and still miss payroll.
The P&L says you're making money. The bank account says something else. This isn't a math error — it's how construction works. The gap between when you spend and when you collect is the financial operating problem that kills more subcontractors than bad bids do. You can win every job right and still go broke if you don't understand the cash cycle.
THE THREE GAPS THAT
DRAIN PROFITABLE SUBS.
Mobilization Comes First
You pay labor and equipment on week one. Your first draw doesn't come for 30–45 days. On a $2M project, that's $80K–$150K out of pocket before you see a dollar.
GC Pay Terms Are One-Sided
Net 30 in the contract becomes Net 60 in practice. Retention sits for 6–18 months. A $500K job with 10% retention has $50K locked up until final punch — sometimes longer.
Overhead Doesn't Stop Between Jobs
Your crew, office, insurance, and equipment cost the same every month whether you're billing $400K or $40K. The slow month hits your cash before it hits your P&L.
WHAT IT LOOKS LIKE
AT $5M REVENUE.
A $5M subcontractor netting 8% has $400K in annual profit. But at any given time they may have $600K–$800K in outstanding AR, $50K–$100K in retention, and $200K+ in current month overhead obligations. Profitable on paper. Cash-constrained in reality.
The real problem: Most subcontractors don't track cash and profit separately. They look at the bank balance and assume it reflects their business health. It doesn't. The bank balance is a lagging indicator — it shows what happened, not what's happening.
WHAT CFOS
FIXES FIRST.
13-Week Cash Forecast — Week by Week
Every inflow and outflow mapped by week. Not a monthly guess — a weekly plan. You see the hole before you fall into it. A $6.7M civil contractor used this to go from a maxed $348K LOC to $309K in the bank in 30 days. See the case study →
Billing Velocity — Front-Load Every Pay App
Schedule of values structured to bill as much as legally defensible in early draws. Mobilization, submittals, and stored materials billed before the GC can push back. This alone moves 15–30 days of cash forward on every project.
AR Recovery — Systematic Not Panic-Driven
A collections routine that runs on a schedule — not when you notice the bank balance dropping. Regular follow-up, lien rights preserved, leverage used before it expires.
