Working Capital Limits Bonding Capacity

Contractors often face a hidden barrier when trying to expand their bonding capacity. A 2026 study by an industry group found that bonding capacity ranks among the top three constraints to growth. Only equipment access and cash flow are more frequently cited as obstacles. Despite this, many wait until they’re desperate for a bond before seeking help, missing opportunities to build the financial foundation that sureties require.

Surety companies don’t operate like lenders. Their role is to guarantee a contractor’s performance on a job, with the contractor personally liable if things go wrong. This means sureties look beyond credit scores or accounts receivable. They want to see a track record of successful projects, systems for managing costs, and a history of timely payments to subcontractors and suppliers. A key factor they scrutinize is working capital—the liquidity a business has available.

Sureties use a formula to determine bonding capacity, with working capital as a central variable. That liquidity can come from cash on hand, lines of credit, or other liquid assets. The high multiplier reflects the risk sureties take on. Contractors often overlook how this ties into their banking relationships, which can further limit their options.

Building a relationship with a surety should start long before a job requires a bond. Contractors who approach surety brokers with a clear business story—detailing their strengths, systems, and lessons from past challenges—often get better results. Transparency about past struggles and how they were addressed can build credibility more effectively than a polished but untested presentation.

When meeting with a broker, contractors should ask targeted questions. Have the broker placed similar companies before? What constraints did those companies face, and how did they overcome them? Contractors looking to grow should ask for real examples of how others increased their bonding capacity. A good broker will provide specifics, not generic reassurances.

Even after securing a bond, risk management remains critical. The indemnity agreement means sureties can pursue personal assets if a job fails. This isn’t a reason to avoid bonded work but a reminder to be selective. Contractors should only take on bonded projects they’ve handled before, with teams, cost histories, and production records in similar environments.

The 2026 study shows contractors recognize this potential. But capturing it starts with intentional financial planning—building relationships with lenders before they’re needed and ensuring working capital supports long-term bonding capacity. The choices made early shape the outcomes later.
