Progress Billing

A pricing model where the contractor bills for actual time spent and materials used, plus markup. Common for work where scope is uncertain.

A contract clause requiring the client to pay for a minimum volume of services or materials, whether used or not. For subcontractors, it provides revenue protection when a project slows down or scopes are cut. Negotiate these clauses carefully to ensure your standby rates and mobilisation costs are covered.

An accounting category tracking costs for projects not yet complete or placed into service. For subcontractors, your invoiced work may sit in a client's CWIP account until project completion. This can affect payment timing and how clients prioritise approving your billings.

A pricing structure where subcontractors charge a marked-up "rack" rate for materials, plus a separate fee for delivery or handling. It allows field service companies to recover supply chain costs beyond base labour rates.

A buffer of extra labour, equipment, or budget set aside to cover unexpected delays or scope changes on a project. Subcontractors use it to avoid cost overruns when field conditions shift. Typically expressed as a percentage of the total estimated project value.

Time when a subcontractor's crew or equipment is on-site but unable to work due to client-caused delays. Most contracts allow billing at a reduced standby rate during this period. Tracking and documenting standby time is critical to recovering these costs.
