Surety isn’t insurance. A surety company isn’t pricing the odds you’ll have a loss, it’s deciding whether to guarantee you’ll finish the job. That decision comes down to three things.
Capital. Your balance sheet, your working capital, and your access to cash. Sureties want to know you can absorb a bad job without putting the project at risk.
Capacity. Whether you can actually do the work. Your track record on jobs this size, your backlog, your equipment, and the people who’d run it.
Character. How you do business. Whether you pay your subs on time, finish what you start, and tell the truth when a job goes sideways. It’s the least quantifiable of the three and often the one that decides close calls.
