AUTHORITY, WORKING CAPITAL

THE SUBCONTRACTOR BALANCE SHEET EXPLAINED.

QUICK ANSWER

A subcontractor balance sheet shows what the business owns, owes, and is worth at a single point in time. The lines that count most for a sub are working capital, retention receivable, and under or overbillings, because bonding companies and lenders read those three first to decide how much risk they will extend to you.

Most owners can read a profit and loss statement and have never opened the balance sheet. That's backwards. The P&L tells you whether last month made money, and it has no say in how big your next job can be. The balance sheet is the document a surety and a bank use to set your bonding line and your borrowing room. Three lines carry almost all of the weight: working capital, retention receivable, and the billing position that reveals whether you're financing your customer or your customer is financing you.

THE DEFINITION

WHAT IT MEANS.

A balance sheet is a statement of a company's assets, liabilities, and equity at a single point in time.

The P&L covers a span of time and the balance sheet covers a single day, which is why the two reports disagree so often. A good month of earnings can sit next to a thin balance sheet when those earnings are still tied up in retention and uncollected receivables. Growth pushes the two further apart, because more work in progress means more of the business's value parked in lines that haven't turned into cash yet.

THE LINES THAT COUNT

WHAT BONDING AND LENDERS READ FIRST.

01

Working capital, current assets minus current liabilities

Working capital is the line that largely sets your bonding capacity, and sureties commonly estimate a bonding line at ten to twenty times the working capital number. It's the first figure an underwriter looks at, ahead of the P&L and ahead of the job list. A subcontractor with thin working capital gets a small bonding line no matter how good last year's net profit looked.

02

Retention receivable, the cash held back until closeout

Retention is cash you already earned that the GC is holding until the job closes, and it belongs on its own receivable line instead of buried inside AR. When it's buried, nobody is chasing it and nobody can say how much of it's sitting out there. Tracked as its own line, it becomes a collectible balance with a release date rather than money you forgot you were owed.

03

Under and overbillings, who is financing who

Underbillings mean you performed work you haven't billed yet, so you're financing the customer out of your own cash. Overbillings mean you billed ahead of the cost you incurred, so the customer is financing you. A healthy subcontractor runs slightly overbilled, and heavy underbillings on the balance sheet are a warning that cash is leaking through billing lag or profit fade.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

What good looks like

For a mature $12M sub, the destination looks like $650,000 in the bank, $1.2M in working capital, and zero debt. A current ratio above 1.3 is the CONTROL Book standard, which means current assets comfortably cover current liabilities. The published outside floor is lower, at the 1.15 to 1.20 minimum standard in CFMA's 2023 surety prequalification guidance, against a construction industry mean of 1.7. Below 1.0 means short term obligations exceed short term assets, and that's a serious liquidity warning regardless of how profitable the jobs look.

HOW SPM FIXES IT

HOW THE BALANCE SHEET OPENS THE DOORS.

Retention tracked as its own receivable, then collected

Retention comes out of AR and onto its own line with a release date attached to each job. Once it has a line, somebody can be accountable for collecting it, which is the whole point of separating it. Retention that nobody tracks is the most reliably forgotten money on a subcontractor's balance sheet.

The billing position corrected so underbillings stop piling up

The billing position gets reviewed against cost incurred every month so heavy underbillings don't build up unnoticed. A slightly overbilled position is the target, because that means the customer is funding the work rather than you. Correcting the position is a billing discipline problem long before it's a financing problem.

Working capital grown so the bonding line rises with it

Working capital grows by keeping profit in the business and by collecting faster, and those are the only two sources. Because sureties commonly size a bonding line at ten to twenty times working capital, every dollar retained buys ten to twenty dollars of capacity to bid larger work. That's the arithmetic that turns a balance sheet into bigger jobs.

COMMON QUESTIONS

FREQUENTLY ASKED.

A balance sheet is a statement of what the business owns, owes, and is worth at a single point in time, where assets equal liabilities plus equity. For a subcontractor it's the document bonding companies and lenders read to decide how much risk to extend, which makes it more important than the P&L for growth and credit.
Three lines carry it: working capital, retention receivable, and under or overbillings. Working capital largely sets your bonding capacity, often estimated at ten to twenty times working capital. Retention should be tracked as its own receivable rather than buried in AR. A slightly overbilled position is healthy, and heavy underbillings signal cash being drained by billing lag or profit fade.
Underbillings mean you've performed work you haven't yet billed, so you're financing the customer. Overbillings mean you've billed ahead of cost incurred, so the customer is financing you. A healthy subcontractor runs slightly overbilled, and heavy underbillings on the balance sheet are a warning that cash is leaking.
A current ratio above 1.3 is the CONTROL Book standard, meaning current assets comfortably cover current liabilities, and lenders and bonding agents read the same figure. Their published floor is lower: CFMA's 2023 surety prequalification guidance sets a minimum standard of 1.15 to 1.20 against a construction industry mean of 1.7, with closer to 1.50 suggesting strong trade partner relationships. Below 1.0 means short term obligations exceed short term assets, which is a serious liquidity warning regardless of how profitable the jobs look.
