Why business credit matters more for GCs than anyone else
For most contractors business credit affects the rate. For a general contractor it affects the size of the job you are allowed to bid, which is a different order of consequence.
The multiplier that runs your business
Most contractors know bonding is gated by financials. Fewer know the arithmetic.
Sureties size capacity as a multiple of adjusted working capital — frequently cited around ten times for aggregate program capacity, with some underwriters working in a ten-to-twenty-times band and setting single-job limits lower than aggregate. A working rule that shows up repeatedly: working capital should be at least 10% of aggregate bonded backlog.
Illustrative only. There is no universal formula — sureties differ, and most weigh working capital against net worth and set limits off the lower figure. Character and claims history matter alongside the numbers.
Read that table backwards and the point lands: every dollar that leaves working capital costs you roughly ten dollars of bonding capacity. That is the lever nobody manages.
Where equipment debt quietly destroys capacity
Here is the mechanic that catches good contractors.
Working capital is current assets minus current liabilities. The current portion of an equipment note — the next twelve months of principal — sits in current liabilities. Shorten the amortization and you increase that current portion, which reduces working capital, which reduces bonding capacity at the multiplier.
A worked illustration. Say you buy a $120,000 telehandler:

Notice the third row. Paying cash removes the liability entirely but removes the cash too — and cash is a current asset. For a bonded GC, buying equipment outright is frequently the worst of the three options for capacity, because it takes the full amount out of working capital immediately rather than spreading it.
Two more things surety underwriters do that contractors rarely anticipate: receivables aged beyond ninety days are commonly excluded from working capital entirely, and heavily held retainage on completed work is a recognized capacity killer. If you are carrying old receivables and a stack of retainage, your bondable working capital is smaller than your balance sheet suggests.
The business credit file itself
Separate from bonding, a real business credit file is what moves a GC from personally guaranteeing everything to borrowing on the company's own strength. The scores that matter:
PAYDEX is worth understanding precisely, because the scale is not intuitive. 80 does not mean excellent — it means you pay exactly on terms. A 100 requires paying roughly thirty days early. A 70 corresponds to about fifteen days late, and a 50 to about thirty days late. Most contractors who think they have good payment behavior are sitting in the seventies.
On the SBSS side, note that the SBA's minimum for 7(a) Small Loans moved to 165, up from 155, effective mid-2025. A great deal of published guidance still cites the old figure.
The trade line problem, which is worse than people think
Here is the part that frustrates contractors who have done everything right.
Of the several hundred thousand suppliers operating in the US, only around ten thousand report account activity to the business credit bureaus — and each decides independently whether and when to report. You can pay every material supplier, every equipment dealer, and every subcontractor on time for three years and still have a nearly empty file.
D&B needs two reporting trade lines and three trade experiences before it will even generate a PAYDEX, and only invoices with payment terms count. From a standing start: a D-U-N-S number in days, vendors reporting over the following months, and a score appearing somewhere around 90 to 120 days. A genuinely strong file usually takes one to three years.
So the practical move is not "pay everyone on time." You are already doing that. It is deliberately concentrating spend with vendors and lenders who report, and asking directly rather than assuming. When you take equipment financing, ask the lender whether they report payment experience and to which bureaus. Many do not, and it costs you nothing to find out before you sign rather than after.
UCC filings: what they do and do not do
When a lender finances equipment it perfects its interest by filing a UCC-1, effective five years and extendable. Those filings appear on your D&B and Experian reports.
Two corrections to common advice. First, a UCC filing does not directly lower your score — it is a cautionary item, not a derogatory mark. Second, and more important: a UCC filing is not a trade line. It is a lien notice. It records that an asset is pledged; it records nothing about whether you pay on time. Advice that says equipment financing builds credit "through the UCC filing" is mechanically wrong — equipment financing builds credit only if the lender reports payment experience.
What does matter is the scope of the filing. An equipment-specific lien encumbers one machine. A blanket lien across all business assets can block future lenders entirely and signals to a reviewer that your assets are already pledged. For a GC trying to preserve borrowing and bonding flexibility, that distinction is worth negotiating.
The bottom line
General contracting runs on thin margins — commonly 12% to 16% gross and 5% to 8% net for well-run firms — against some of the slowest payment cycles in any industry. In that structure, capacity is the constraint, and capacity is arithmetic.
Protect working capital, structure equipment debt over terms that keep the current portion small, chase down receivables before they cross ninety days, and build a reportable credit file on purpose rather than by accident. Our guide to corporate only equipment financing covers what it takes to borrow without a personal guarantee once that file exists.
Frequently asked questions
How is bonding capacity calculated?
Sureties generally set capacity as a multiple of adjusted working capital, frequently around ten times for an aggregate program, with single-job limits set lower. Many underwriters compare working capital against net worth and base limits on the lower of the two. A common working rule is that working capital should equal at least 10% of aggregate bonded backlog. There is no universal formula and practices vary by surety.
Does equipment financing hurt a contractor's bonding capacity?
It can, depending on structure. Working capital is current assets minus current liabilities, and the next twelve months of principal on an equipment note sits in current liabilities. A shorter amortization increases that current portion, reducing working capital and therefore bonding capacity at the surety's multiplier. Paying cash removes the liability but also removes the cash, which for a bonded contractor is often the worst outcome for capacity.
What is a good PAYDEX score for a contractor?
80 is the threshold figure, and it means paying exactly on terms rather than paying well. Scores approaching 100 require paying roughly thirty days ahead of terms, while 70 corresponds to about fifteen days late and 50 to about thirty days late. Anything in the 80 to 100 band reads as low risk to a reviewer.
Why does my business credit file look empty when I pay everyone on time?
Because most suppliers do not report. Of the several hundred thousand suppliers operating nationally, only roughly ten thousand report account activity to the business credit bureaus, and each chooses independently whether and when to do so. D&B also requires two reporting trade lines and three trade experiences before generating a PAYDEX at all. Paying on time only builds a file if the counterparties actually report it.
Do UCC filings lower business credit scores?
No, not directly. UCC-1 filings appear on business credit reports as cautionary items rather than derogatory marks. What matters more is scope: an equipment-specific filing encumbers one machine, while a blanket lien across all business assets can block future lenders and signals that assets are already pledged. It is also worth noting that a UCC filing is a lien notice, not a payment trade line, so it does not build credit on its own.
