The 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.
Operating Days
Related Terms
Adjusted Ebitda (earnings Before Interest, Taxes, Depreciation and Amortisation)
Cash FlowA profitability measure that strips out non-cash costs and one-time charges, showing true operational earnings. For subcontractors, it reveals how much cash your field operations actually generate. Clients and lenders use it to assess your financial health before awarding contracts or extending credit.
Work on Hand (WOH)
Cash FlowThe total value of contracted work that has not yet been completed. Used by bonding companies to assess contractor capacity and risk.
Estimating Backlog
Cash FlowThe queue of pending bids and quotes a subcontractor has not yet completed or submitted to clients. A large estimating backlog can delay securing new work and strain small estimating teams. Tracking it helps prioritise high-value opportunities and allocate quoting resources effectively.
Pay-When-Paid
Cash FlowA contract clause where a general contractor delays paying subcontractors until the owner pays them first. This shifts financial risk downstream to subcontractors and field service companies. Review these clauses carefully, as they can significantly impact your cash flow on long projects.
RFQ (Request for Quote)
Cash FlowA formal document issued by prime contractors or operators asking subcontractors to submit detailed pricing and specifications for specific field services, equipment, or labour. RFQs typically include project scope, timelines, and technical requirements that subcontractors must address to compete for the contract.
Brent Futures
Cash FlowContracts that lock in a future price for North Sea crude oil, used as a global benchmark. When Brent prices drop, operators often cut budgets and delay projects, directly reducing subcontractor workloads. Tracking Brent futures helps field service companies anticipate slowdowns and plan their crews and bids accordingly.
