A legal claim registered against a property or asset when a subcontractor hasn't been paid for work or materials. It prevents the owner from selling or refinancing until the debt is settled. In oil and gas and construction, liens are a key tool for protecting payment rights.
Lien
Related Terms
LEM (Labour, Equipment, Materials)
Cash FlowA breakdown of costs on a field ticket or invoice, separating charges into labor hours, equipment usage, and materials consumed.
Early Payment Discount
Cash FlowA reduced invoice amount offered to prime contractors or clients who pay before the standard due date. Common terms like 2/10 Net 30 mean a 2% discount if paid within 10 days. Subcontractors must weigh the cash-flow benefit against the revenue they give up.
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.
Backcharge
Cash FlowA charge issued by an operator or general contractor to a subcontractor for costs incurred due to defective work, delays, or failure to meet contractual obligations.
Breakeven Cost
Cash FlowThe minimum amount a subcontractor must charge to cover all project expenses without making a loss. It includes labour, equipment, fuel, insurance, and overhead. Pricing below breakeven erodes margins and can threaten business viability.
Heating Oil Futures
Cash FlowContracts locking in future heating oil prices, traded on commodity markets. Subcontractors use these trends to forecast fuel-related operating costs on remote or winter job sites. Rising futures signal higher equipment heating and site fuel expenses ahead.
