Loaded Labour Rate

A measure of how long a company takes to pay its invoices after receiving them. For subcontractors, a high DPO from your client means slower payment and tighter cash flow. Tracking client DPO helps you anticipate payment delays and manage operating costs.

The process a prime contractor or operator uses to review, approve, and finalise invoices before releasing payment to subcontractors. Understanding the settling system helps subs forecast cash flow and avoid payment delays. Timelines vary widely between clients, so confirm the cycle before mobilising.

An arrangement where costs for equipment, mobilisation, or resources are split between the contractor and client. Subcontractors should confirm cost-sharing terms in writing before mobilising. Unclear agreements often lead to disputed invoices and delayed payments.

A directive where a contractor is authorised to begin work before a formal purchase order is issued. The subcontractor agrees on a price verbally or in writing, then mobilises immediately. Common in urgent field situations, but carries payment risk if terms aren't confirmed in writing.

A variable fee added to invoices to recover fuel cost fluctuations on equipment-heavy jobs. Subcontractors often tie it to a published index, such as the weekly rack price. Review prime contracts carefully — some owners cap or exclude surcharges entirely.

A disconnect between what a subcontractor quoted and what the client expects to pay for. This often surfaces during invoicing when scope, rates, or billing terms were not clearly agreed upon upfront. It can delay payments and strain relationships with prime contractors.
