Lien

A fee billed to clients to reserve your crew, equipment, or services during a set period — whether fully utilised or not. It protects subcontractors from revenue loss during standby or low-demand phases. Common in long-term service agreements for drilling, frac, or maintenance contracts.

Expected fluctuations in workload, crew demand, and billing cycles tied to specific times of year. In oil & gas and construction, busy seasons drive higher rates and faster payments. Slow seasons often mean delayed invoices, reduced headcount, and tighter cash flow.

A signal that a client or project poses serious financial or operational risk to a subcontractor. Common triggers include late payments, scope disputes, or sudden crew access restrictions. Recognising these early helps subcontractors protect revenue and avoid costly disputes.

A measure of a subcontractor's core operating profitability, stripping out financing and accounting costs. It helps field service companies assess whether their contracts and crews are generating real operational value. Clients and lenders often use it to evaluate a subcontractor's financial health before awarding work.

A pre-agreed financial penalty charged when a subcontractor misses deadlines or fails to meet contract milestones. The amount is fixed in the contract, not calculated after the fact. LDs can seriously erode your project margins if schedule risks aren't managed upfront.

A 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.
