Daily oil & gas and construction news for subcontractors

Cash FlowGlossary Term

Diesel Surcharge

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.

Related Terms

Natural Gas Futures

Cash Flow

Contracts that lock in a future price for natural gas, traded on commodity markets. When futures prices drop, upstream clients often cut budgets and delay field work. Subcontractors should monitor futures as an early signal of upcoming project slowdowns or cancellations.

Base Load

Cash Flow

The guaranteed minimum volume of work a client commits to a subcontractor over a contract period. It provides predictable revenue and helps justify keeping crews and equipment on standby. Subcontractors use base load commitments to stabilise cash flow between project spikes.

SRF (State Revolving Fund)

Cash Flow

A government-backed loan programme that funds municipal water, wastewater, and infrastructure projects. These funds often finance large construction contracts, creating steady work for subcontractors and field service crews. Knowing a project is SRF-funded signals stable, government-secured payment on long-term builds.

Tolling Agreement

Cash Flow

A contract where a subcontractor processes or treats a client's raw material using your equipment or facility, without taking ownership of it. You charge a fee for the service rather than buying and reselling the material. Common in midstream and processing work, it directly affects how you invoice and recognise revenue.

Joint Check

Cash Flow

A payment cheque issued by a general contractor made payable to both the subcontractor and their supplier or creditor simultaneously. It ensures supplier invoices are paid directly from project funds, reducing lien risk. Subcontractors must endorse the cheque alongside the named party before cashing it.

DPO (Days Payable Outstanding)

Cash Flow

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.
