A formal document filed by a subcontractor to preserve lien rights on a project before work begins or early in the job. It notifies the property owner and general contractor that you have a financial stake in the project. Without it, you may lose the right to file a lien if payment is withheld.

Operating Days
Cash FlowThe number of days equipment or crews are actively deployed and generating billable revenue on a job site. Subcontractors use this figure to track utilisation, forecast earnings, and negotiate day-rate contracts. Downtime, mobilisation delays, or weather shutdowns typically do not count as operating days.
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.
Face Exposure
Cash FlowThe total dollar value of unpaid invoices a subcontractor has outstanding with a single client at any given time. High face exposure increases financial risk if a client delays payment or becomes insolvent. Subcontractors should monitor face exposure closely to avoid over-reliance on one payer.
Policy Rate
Cash FlowThe interest rate set by the Bank of Canada that influences borrowing costs across the economy. When it rises, lines of credit and equipment financing become more expensive for subcontractors. It also affects how quickly clients pay invoices, tightening cash flow across the field service sector.
Buyout
Cash FlowA lump-sum payment made to a subcontractor to settle or terminate a contract early. It compensates for remaining work, mobilisation costs, or lost profit margins. Subcontractors should verify buyout terms are clearly written into their agreements before signing.
Day Rate
Cash FlowA pricing model where contractors are paid a fixed daily rate for equipment and/or personnel, regardless of the amount of work completed that day.
