Legal protections allowing subcontractors to place a claim against a property or project if payment is withheld. Filing a lien can prevent an owner from selling or refinancing until your invoice is settled. Deadlines to file are strict and vary by province, so act quickly when payment stalls.

Contingent Payment
Cash FlowPayment tied to a specific condition being met, such as project completion or client approval. Subcontractors must track these triggers carefully to invoice on time. Delayed conditions can create serious cash-flow gaps in the field.
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.
Project-Level Debt
Cash FlowFinancing borrowed against a specific project's revenue, not the owner's overall assets. Subcontractors should know this because payment depends on that project performing financially. If the project underperforms, your invoices may be delayed or disputed.
Fixed-Rate Contract
Cash FlowA contract where the subcontractor agrees to complete a defined scope of work for a set price, regardless of actual labour or material costs incurred — meaning cost overruns come directly out of your margin. Common in construction and turnaround work, these contracts reward efficient crews and tight project management but carry significant financial risk if scope creep or site conditions aren't carefully managed upfront.
Quantity Drift
Cash FlowThe gradual increase or decrease in actual field quantities compared to original contract estimates. For subcontractors, untracked drift leads to unbilled work or disputed invoices at project close-out. Monitor quantities continuously to support change order claims.
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.
