Convertible Notes
Cash FlowShort-term loans that convert into equity if not repaid by a set date. Subcontractors may encounter these when seeking growth capital to fund equipment or crew expansion. They carry risk: lenders can become part-owners of your company.
Unplanned Outage
Cash FlowA sudden, unscheduled shutdown of equipment or operations that halts field work without prior notice. For subcontractors, it often triggers standby time disputes and delayed milestone billing. Contracts should clearly define compensation terms for crew and equipment during unplanned downtime.
Progress Billing
Cash FlowInvoicing for work completed to date on a longer project, rather than waiting until project completion. Helps subcontractors maintain cash flow on extended jobs.
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.
Operating Breakeven
Cash FlowThe minimum revenue a subcontractor must generate to cover all field operating costs without profit or loss. It includes direct costs like labour, fuel, and equipment. Knowing this figure helps crews avoid underpriced bids that drain cash.
Fuel Cost Escalator
Cash FlowA contract clause that adjusts your billing rate when diesel or fuel prices shift beyond a set threshold. It protects subcontractors from absorbing sudden fuel cost spikes on long-term or remote field assignments. Negotiate the trigger percentage and index reference before signing.
