The season sets the shape. In most markets the paving window runs spring through fall; in northern states it is tighter still. Everything the season earns must carry the off-season’s fixed costs — retained operators and foremen, equipment payments that do not hibernate, insurance, the yard — plus the pre-season spend: maintenance and rebuilds on the fleet, mobilization for early jobs, and material commitments as plants reopen. The cash low point is predictably late winter, right when next season’s prep bills arrive. A seasonal line of credit, drawn through the trough and repaid across the season, is the standing answer — sized from last year’s monthly cash curve, not from annual revenue.
The iron is both the cost and the answer. Paving equipment is expensive, durable, and — crucially — holds appraisal value in a deep resale market. New units belong on equipment financing matched to their working life. But the underused move in this trade is the reverse: an equipment refinance or sale-leaseback on machines owned free and clear, converting parked equity into the working capital the season demands. For an established paving company, the fleet is usually the cheapest capital it can raise — cheaper than any unsecured loan, and much cheaper than the advances too many contractors take instead.
Public work pays like public work. DOT resurfacing, municipal streets, and school or utility lots are bedrock revenue with excellent credit behind them — and payment cycles stretched by measurement, inspection, and processing, often with retainage on contract work. Crews, fuel, and asphalt were paid weeks earlier; see payroll between draws for that mechanism. Government receivables are strong collateral precisely because the payer is certain: receivables financing against them converts the state’s timeline into yours. Growing paving companies bidding bonded public work should also read the bonding capacity page — the working-capital math there decides how much of that bedrock you can bid.
