Cost-Escalation Clause
Cash FlowA contract provision allowing subcontractors to adjust their rates when material, labour, or fuel costs rise beyond a set threshold. It protects field service companies from absorbing unexpected cost increases on long-term projects. Without one, subcontractors are locked into original pricing regardless of market changes.
Rule 144a
Cash FlowA U.S. securities regulation allowing large private companies to raise capital without a public stock listing. For subcontractors, it signals a major client may have access to significant private funding. This can affect contract stability and payment capacity on large projects.
Job Costing
Cash FlowThe process of tracking all costs associated with a specific job or project, including labor, equipment, materials, and overhead. Accurate job costing is essential for understanding profitability.
Breakeven Price
Cash FlowThe minimum rate a subcontractor must charge to cover all direct and indirect costs without losing money. It includes labour, equipment, fuel, overhead, and mobilisation expenses. Pricing below breakeven erodes working capital and threatens project viability.
FCF (Free Cash Flow)
Cash FlowCash remaining after covering operating costs and equipment or tool purchases. For subcontractors, strong FCF means you can take on new contracts, absorb payment delays, and avoid emergency borrowing. It is one of the clearest signs of a financially healthy field service business.
DSO (Days Sales Outstanding)
Cash FlowThe average number of days it takes to collect payment after a sale. For field service companies, DSO measures how long between completing work and receiving payment. Industry benchmarks range from 30-60 days.
