Subcontractor (SC)
What is a Subcontractor (SC)?
A subcontractor, also known as a trade contractor, is a specialized construction professional that a general contractor (GC), construction management property, owner, developer, or other entity hires to perform specific work on a construction project. Subcontractors typically specialize in a particular trade or craft, such as electrical work, plumbing, HVAC installation, framing, roofing, glazing, flooring, or drywall installation. They are bound by a contract that outlines the tasks they need to perform as well as deadlines and terms of payment.
Subcontractors are distinguished from GCs in several ways. GCs oversee the entire construction project, managing all aspects from start to finish, including coordinating subcontractors, obtaining permits, and ensuring compliance with building codes and regulations. Subcontractors, on the other hand, focus solely on their specialized area of work and are responsible for completing their specific tasks according to the project's plans and specifications.
Subcontractors face extensive payment cycles, as they cover all labor and material costs upfront for a project yet receive payment last. Progress billing further complicates the matter, mandating that GCs only reimburse subcontractors based on project completion percentage. This system requires subcontractors to invoice GCs every month for the work completed, which exposes them to various factors that can delay progress billing further. These include:
- using the wrong pay application form,
- missing documentation,
- lien waiver oversights,
- submitting pay apps through the wrong GC portal,
- general project delays and disputes, or
- the GC’s own cash flow issues.
As a result, most subcontractors wait about 90 days to get paid for the work they’ve already done, which can strain their cash flow and hamper their ability to take on new projects or pay their employees and suppliers.
This is where Siteline comes in. Siteline is a construction billing solution built specifically to streamline the subcontractor A/R workflow. With Siteline, trade contractors can easily generate and submit detailed pay apps tailored precisely to each GC's requirements. The platform also:
- tracks all compliance requirements and stores pertinent documents;
- tracks, collects, and submits lien waivers for the sub and their lower tiers;
- ensures approved change orders are incorporated into the schedule of values;
- provides full visibility into billing statuses across projects—including which GCs pay fastest to better anticipate cash flow; and
- creates accurate billing projections to monitor progress and effectively manage backlog.
By eliminating manual spreadsheets and centralizing all billing data, Siteline helps trade contractors accelerate their payment cycle by an average of three weeks. Discover how Siteline can get your subcontracting business paid faster by scheduling a demo today.

Other construction terms
What is a G702?
A G702 is a document form used in the construction industry known as the Application and Certificate for Payment. It is issued by the American Institute of Architects (AIA) and is used by contractors to apply for payment for the work completed and materials supplied on a project. It details the contractor's progress on the project, summarizing the total project to date, change orders, previous payments, and the current payment due. The form needs to be signed by the contractor, the architect, and the owner, certifying that the work has been completed and payment is deserved.
What are Uninstalled Materials?
Uninstalled materials refer to construction materials that have been purchased but are yet to be put in place or installed in a construction project. They are typically stored on-site or at a secure location and are accounted for in a contractor's Work-In-Progress report. These materials may include items like bricks, steel, concrete, wood, electrical wiring, piping, insulation, and fixtures. It is crucial for project managers to properly track and manage these materials as they represent a significant investment and, if misplaced, lost, or damaged, could lead to costly delays and overruns in the project. Their handling requires proper planning to ensure safe storage, timely installation, and effective use in the construction process.
What is percentage of completion?
Percentage of completion (POC) is a metric that represents the proportion of work completed on a construction project at a given point in time. It is expressed as a percentage of the total contracted work. The POC is important to subcontractor workflows for several reasons:
- Payment schedules: Most construction contracts stipulate that subcontractors receive payment based on the percentage of work completed rather than a lump sum payment at the end of the project. The POC determines the amount of payment that a subcontractor can request from the general contractor (GC) or the project owner for the work performed during a specific billing period.
- Cash flow management: Subcontractors rely on progress payments to maintain a healthy cash flow and cover expenses such as labor, materials, and equipment. The POC directly impacts the timing and amount of progress payments received, allowing subcontractors to plan and manage their financial resources effectively.
- Project monitoring and control: Tracking the POC helps subcontractors monitor their progress against the project schedule and budget. It enables them to identify potential delays or cost overruns early on, allowing for prompt corrective actions.
- Dispute resolution: In the event of disputes or claims related to payment or project delays, POC documentation can serve as evidence to support the subcontractor's position and substantiate their claims for outstanding payments or compensation.
- Resource allocation: By monitoring the POC, subcontractors can better plan and allocate their resources (labor, materials, equipment, etc.) across multiple projects, ensuring efficient utilization and avoiding resource conflicts or shortages.
- Project closeout: The POC is crucial during the project closeout phase, as it helps determine the final payment due to the subcontractor and ensures that all work has been completed according to the contract terms.
Overall, POC serves as a versatile tool throughout the entire project lifecycle, from initial payment requests to final closeout. And with Siteline, managing POC workflows becomes effortless. Siteline makes progress billing a cinch by:
- Generating custom pay applications with real-time POC calculations
