You run five active projects simultaneously. Each has a different GC, different payment schedule, different retainage terms, and different subcontractor obligations. Cash flows in from one project while it flows out to mobilize another. A single delayed progress payment on one job cascades across the others.
A $2M commercial project requires $400K in mobilization costs before the first application for payment. Subcontractors need progress payments within 30 days. The GC pays applications on a 30-45 day cycle. Retainage holds 10% until final completion, 12-18 months from mobilization. Across five projects, retainage alone locks up $800K-$1.2M in capital you have earned but cannot access. Meanwhile, bonding capacity depends on working capital ratios that these timing gaps erode.
