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;

What is Enterprise Resource Planning (ERP)?
Enterprise Resource Planning (ERP) in the construction industry refers to a suite of integrated software applications designed to automate and control the core processes of a construction company. It serves as a central platform that facilitates the flow of information among different business functions such as accounting, human resources, procurement, project management, risk management, and compliance. ERP systems simplify data-driven decision making by providing real-time insights into every aspect of the construction project which include, but aren't limited to, project costing, inventory management, and workforce allocation. By enhancing visibility and streamlining workflows, ERP systems can significantly boost productivity and efficiency in the construction sector.
What is Actual Cost?
Actual cost, in the construction industry, refers to the accurate amount reasonably spent on a project. This includes every expense incurred during the planning, development, and execution phases. The actual cost often encompasses material expenses, labor charges, equipment costs, and any additional overhead related to the project. For instance, the cost of bricks, cement, construction tools, and an hourly wage for workers constitutes the actual cost. It may differ from the estimated cost due to unforeseen circumstances or changes in the project scope. Monitoring the actual cost is vital for maintaining a project's budget and preventing financial oversights.
What is overhead allocation?
Overhead allocation in construction is the accounting method of distributing indirect operational costs—such as equipment rental, insurance, field supervision, and software—across specific projects, jobs, or cost codes.
Because indirect expenses cannot be billed directly to a single line item, trade contractors allocate overhead using baseline metrics like direct labor hours, direct labor costs, or total contract value. Proper overhead allocation ensures accurate job costing, prevents underbidding, and protects profit margins across all active jobs.
How Siteline Helps:
Uncovering true job profitability requires steady, predictable cash flow. Siteline streamlines pay application workflows, lien waiver tracking, and billing cycles so trade contractors get paid faster and recover allocated overhead expenses on schedule.
