Nonresidential Inputs

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 contract where the subcontractor agrees to complete a defined scope of work for a set price regardless of actual labour, equipment, or material costs incurred — meaning cost overruns come directly out of your margin. Unlike time-and-material agreements, these contracts reward efficiency but expose field service companies to significant financial risk if scope creep or unforeseen site conditions arise.

A legal claim registered against a property when a subcontractor hasn't been paid for work or materials provided. It secures your right to payment by encumbering the owner's title. Filing deadlines are strict, so act quickly if invoices go unpaid.

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 standardised daily report documenting rig operations, hours worked, and downtime on a drilling project. Subcontractors often must align their own daily reports with the IADC DDR for invoicing and performance verification. Discrepancies between your records and the DDR can delay payment or trigger billing disputes.

Revenue that is earned but never collected due to operational inefficiencies. Common causes include lost field tickets, unbilled equipment hours, forgotten third-party charges, and documentation errors. Industry estimates suggest 1-5% of revenue is lost to leakage in paper-based operations.
