Cash flow: why profitable contractors still go broke
You can be booked solid and profitable on paper and still not make payroll. Cash flow — not profit — is what actually keeps the doors open.
Here's the trap that sinks busy trades businesses: profit and cash are not the same thing. You can finish a great month on paper and still be unable to buy materials or pay your crew, because the money's tied up in unpaid invoices and upfront costs. Understanding cash flow - the actual timing of money in and out - is what separates the shops that survive from the ones that fold mid-growth.
The gap that kills you
You pay for materials and labor now; the customer pays you later - sometimes much later. That gap is where businesses die. A big job can actually drain your cash before it ever pays out, so 'more work' without managing the timing can make things worse, not better.
Get money upfront
The single biggest cash-flow fix: stop financing your customers' projects out of your own pocket. Take a deposit before you start, and progress payments on bigger jobs. It's standard, customers expect it, and it keeps your materials and payroll covered.
- Deposit before you start work or order materials.
- Progress payments tied to milestones on larger jobs.
- Final balance due on completion, not 'whenever.'

Scan my businessKeep a cushion
Aim to keep enough cash to cover a slow stretch - a few weeks of payroll and fixed costs. It's your shock absorber for a dead season, a late-paying customer, or a surprise repair. Build it in the good months so the lean ones don't become emergencies.
“I was profitable and still sweating payroll every month. Once I started taking deposits and invoicing same-day, the stress just... went away.”
Profit is theory; cash flow is survival. Get deposits, invoice immediately, get paid fast, and keep a cushion - so a slow month or a late-paying customer doesn't take you down.
Common questions
Profit is revenue minus costs over time. Cash flow is the actual timing of money entering and leaving your account. You can be profitable but cash-poor if you're paid slowly - and that's what causes failures.
Enough to cover materials and early labor - often a meaningful percentage upfront, with the rest on milestones or completion. Standard practice customers expect.
That's a red flag. Serious customers understand deposits; the ones who refuse are often the ones who'll be hardest to collect from later.
