Callbacks

A formal written amendment to an existing contract that modifies scope, cost, or schedule. Subcontractors should never perform out-of-scope work without a signed change order. Undocumented changes are a leading cause of unpaid invoices and disputes.

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.

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

A court order declaring a prime contractor in default on financial obligations, often freezing payments to subcontractors. It signals serious insolvency risk and can delay or eliminate outstanding invoices. Subcontractors should file liens immediately upon receiving notice.

A breakdown of costs on a field ticket or invoice, separating charges into labor hours, equipment usage, and materials consumed.

Financing borrowed against a specific project's revenue, not the owner's overall assets. Subcontractors should know this because payment depends on that project performing financially. If the project underperforms, your invoices may be delayed or disputed.
