According to research by Mobilization Funding, commercial construction firms report strong backlogs and steady demand, but cash flow timing continues to limit how much work they can take on.
A 2026 survey of 250 U.S. contractors and subcontractors found that upfront project costs, including materials, labor and equipment, often arrive well before payments, creating pressure on working capital.
That gap is affecting business decisions. Ninety percent of respondents said they have passed on profitable projects due to cash flow timing, while all respondents said it influences whether they pursue new work.
The challenge is contributing to a broader industry dynamic: companies remain busy but are unable to scale at the same pace.
Growth Meets Constraints
More than three-quarters of firms described their businesses as growing, yet that expansion is adding strain across operations. Contractors cited equipment availability as the top constraint on taking on additional work, followed by cash flow, bonding capacity and labor.
Financial pressure often intensifies when projects are awarded. Multiple job starts, upfront material purchases and labor ramp-up were identified as leading cost drivers before billing begins.
Cash Flow Drives Decisions
Cash flow timing is shaping which projects move forward. Nearly 60% of respondents said it frequently or always acts as a deciding factor, with many firms adjusting hiring, delaying investments or limiting growth to manage risk.
The strain is also personal. Most respondents said managing upfront costs while pursuing growth creates ongoing stress, reflecting the uncertainty around when payments will be received.
Fragmented Funding Strategies
Contractors are relying on a mix of funding sources to bridge the gap, including owner deposits, lines of credit, internal reserves and supplier financing. No single approach dominates, with many firms piecing together multiple options.
Survey respondents indicated that improved access to capital could accelerate project timelines, reduce financial pressure and strengthen vendor relationships.
Outlook
While demand remains strong, the timing mismatch between project costs and payments continues to shape contractor growth strategies. For many firms, the ability to manage that gap will determine how aggressively they can pursue new opportunities.
