GROWTH EATS CASH BEFORE IT MAKES ANY.
Every additional million dollars of revenue requires cash up front for labor, material, and mobilization, and collects 60 days later. That's why a contractor can double revenue and end the year with less money than they started with. Working Capital is the CFOS module that sets how much growth your balance sheet can carry and builds the reserve that makes the next size of work possible.
Working capital is your current assets minus your current liabilities, and it's the number a bank or a surety looks at first because it answers whether you survive a bad month. The target is 10 to 15 percent of annual revenue, and 13 percent is where a company stops being fragile. A contractor at $10M with $500,000 of working capital is at 5 percent, which reads as overextended however profitable the jobs are, and that number is what caps the bond and prices the loan. Growth without a balance sheet plan doesn't fail because the work was bad, it fails because the company outran its own reserve.
WHAT HAPPENS WITHOUT THIS SYSTEM.
Revenue grows and cash gets worse
Taking on a job 40 percent larger than your usual size means funding 40 percent more labor and material before the first pay application is approved. The job may carry an excellent margin and still consume every dollar of reserve for four months. Owners read the shrinking bank balance as a profitability problem when it's the cost of the growth they chose.
The bonding limit stops moving
A surety sets your single job and aggregate limits from working capital and equity, not from your backlog or your reputation. A contractor who wants bigger work but has a thin balance sheet gets the same limit renewal after renewal, with no explanation that changes anything. The limit moves when the balance sheet moves, and nothing else does it.
Equipment purchases become short term debt
Buying a skid steer or a truck out of operating cash converts a current asset into a fixed one, which drops working capital and the current ratio at the same time. Financing it over five years instead keeps the reserve intact, but only if the payment was planned against the forecast. A profitable year followed by a December equipment run is how a company ends up with strong equity and a current ratio below 1.0.
WHAT OWNERS THINK IS WRONG. WHAT IS CAUSING IT.
What owners think: Owners assume the answer to a tight balance sheet is more revenue, so they bid more work and take on the largest job they've ever run.
What's causing it: Revenue is the multiplier and the balance sheet is the constraint, so adding revenue to a thin balance sheet accelerates whatever is already happening. If the jobs earn 10 percent net, growth compounds it, and if they earn nothing, growth compounds that too while consuming the reserve either way. The order of operations is to fix margin, shorten the collection cycle, build working capital to 13 percent, and then grow into the capacity you built.
WHAT THIS MODULE DELIVERS.
WHERE IT HITS HARDEST.
Equipment heavy balance sheets with seasonal revenue
Civil contractors carry the most fixed assets and the most seasonal revenue of any trade we work with, which is the hardest combination for a current ratio. Equipment notes are due all twelve months while billings happen in eight. Building the reserve to carry the two slow months is the difference between a strong balance sheet and an annual line of credit.
Large equipment purchases inside a single job
A mechanical sub can be asked to buy a rooftop unit or a chiller representing a quarter of the contract value before any of it's billable. That single purchase can move working capital by six figures for a quarter. Whether it's funded from reserve, from a supplier term, or from the line changes the balance sheet for the rest of the year.
Material bought at the front of the job
Steel is purchased and fabricated well before erection, so the cash goes out at the beginning and comes back at the end. On a large project the negative position can run four to six months. Sureties know this, which is why steel fabricators are underwritten harder on working capital than most trades.
THE OUTCOME IN PLAIN NUMBERS.
The change here is slower than the other modules and it's the one that decides what the company can become. Moving working capital from 5 percent of revenue to 13 percent takes retained profit, a shorter collection cycle, and a deliberate stop on cash equipment purchases, and it usually takes three to six quarters.
What it buys is capacity. The bonding limit moves, the borrowing rate drops, the company can take a job 50 percent larger than its previous largest without gambling, and a slow quarter stops being a threat. A contractor running the full system holds roughly $650,000 in the bank at all times, and that number is what lets the owner take a week off without the business needing them.
