Lesson 3 ended with a riddle. You earned 11% and you can't make payroll. Here's why both are true.
Profit is measured over the life of a job. Cash is measured day by day. Between the day you pay for materials and the day the customer's check clears, your business is spending money it hasn't received. The job is profitable. Your bank account doesn't know that. The bank account only knows the calendar.
01
The gap, measured
Three dates decide everything:
- First pay-out. The day money leaves for materials, mobilization, first draws to subs.
- Last collection. The day the final check actually clears. Not the invoice date. The cleared date.
- The stretch in between. Every day in that window, your cash is financing the job. You are, whether you meant to or not, lending money to your customer.
Contractors who feel "busy but broke" aren't bad at business. They're good at business and blind to the calendar. The gap is the reason.
02
Two dimensions, two decisions
The gap has a depth and a duration, and they are set by different things. The depth, the maximum shortfall, is decided by what you spend and when, against what you have collected by then. The duration, how long the account stays below zero, is decided by when the money comes back. A customer who pays in sixty days instead of forty-five does not dig the hole deeper. The hole was dug by your own expenditures. The customer just leaves you standing in it longer.
To shrink the depth: move money in earlier, or spend later. To shorten the duration: collect faster. Deposits do both at once, which is why they are the strongest lever.

Move the final collection day and watch which result moves.
04
Three levers that shorten the gap
Deposits, draws, and terms. Deposits move the first collection before the first pay-out. Draw schedules move collections closer to the work. Terms move pay-outs later. Most contractors use none of the levers because none of them feel like "how we do things." The gap grows on custom.
MIKE'S EXAMPLE
Mike · General contractor, 43
Mike mapped the bathroom job on a calendar. Bid $43,300. The cash that actually left for this job: $33,700. The $4,800 invoice share is an allocation, not a check written for this bathroom.
Without structure, the money dates:
- Day 0: nothing happens. No deposit.
- Day 15: materials, $19,250. Balance: negative $19,250.
- Day 30: labor and subs, $14,450. Balance: negative $33,700.
- Days 30 through 44: the job holds him at negative $33,700.
- Day 45: the customer's check clears. Balance: positive $9,600.
Thirty days below zero, and the deepest point, negative $33,700, sat there for two weeks, in the same weeks his other jobs were in their own gaps. Run the counterfactual: had the customer paid on day 60 instead of day 45, the deepest point wouldn't move. Negative $33,700, set on day 30 when the sub invoices hit. What changes is the wait: forty-five days below zero instead of thirty.
Now the Lesson 3 connection. The bathroom's actual profit was $4,800. The job burned cash at $33,700 across 45 days, about $749 a day. Divide one by the other: $4,800 finances 6.4 days of that calendar. One job's profit barely funds a week of the next job's gap. That's how three profitable jobs can starve a company.
Mike's fix wasn't more profit. It was structure: a 30% deposit, $12,990, before materials, and a $16,000 progress draw on day 30. New timeline: bottom at day 15 at negative $6,260. Day 30 lands at negative $4,710. The check that clears on day 45 is $14,310 and the job finishes at positive $9,600, same margin, same customer. The deepest point fell from $33,700 to $6,260, because the first money in now arrives before the first money out.

Map Your Last Job's Money Dates
One job, three dates: first pay-out, last collection, and the day the account was lowest. Count the days between. Write one sentence: what would have to change to cut that stretch in half? Deposit, draws, or terms. Pick one and name the customer conversation it requires.
