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.Â
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,Â
- missing documentation,Â
- lien waiver oversights,Â
- submitting pay apps through the wrong GC portal,Â
- general project delays and disputes, orÂ
- 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:

What are Payment Applications (Pay Apps)?
A payment application (or pay app) is a comprehensive collection of documents that construction contractors submit to request progress payments throughout a project. Rather than just a simple invoice, payment applications include multiple forms and supporting documentation that prove what work was completed, which materials were used, and what payment is due. The typical pay app package includes:Â
- an application for payment form,Â
- a continuation sheet with schedule of values details,Â
- lien waivers, andÂ
- often backup documents like material receipts and payroll reports.Â
Payment applications are submitted on predetermined schedules—whether monthly, at project milestones, or when specific percentages of work are completed—and serve as the primary billing mechanism for longer, higher-budget construction projects.
For subcontractors, mastering payment applications is critical because they directly impact cash flow and project profitability. The process involves coordinating between accounting teams, project managers, and vendors to gather all required documentation before submission deadlines. Common mistakes—like using incorrect forms, missing documentation, math errors, or late submissions—can delay payments and disrupt cash flow. Many GCs have their own custom forms and specific requirements, making attention to contract details essential.Â

What is Cost Accounting?
Cost accounting in construction is a specialized accounting practice that captures, records, and analyzes all costs incurred during construction projects. This includes direct costs like materials, labor, and equipment, as well as indirect costs such as project management, insurance, and overhead allocation.Â
Unlike general accounting, which focuses on overall financial reporting, cost accounting drills down into the specifics of where every dollar goes on each project. It's designed to provide detailed insights into project profitability by tracking costs against budgets in real-time, helping construction teams understand not only how much they're spending, but also whether that spending aligns with projected margins and timelines.
Siteline helps subcontractors maximize the value of their cost accounting by streamlining the entire accounts receivable (A/R) process that turns project costs into collected payments. Our platform generates custom pay applications, manages compliance documentation, tracks change orders, and provides real-time A/R reporting, ensuring that all the financial insights from your cost accounting translate into faster, more predictable cash flow.

What is a Budget Analysis?
A Budget Analysis in the context of the construction industry is a comprehensive review and assessment of all estimated costs associated with a construction project to ensure fiscal responsibility and efficiency. This includes analyzing labor costs, material expenses, equipment needs, subcontractor bids, project timeline, contingencies, and overheads among others. The aim is to determine the economic viability of the project, identify any potential financial risks, and devise strategies to manage and control costs. It plays a critical role in project management, helping construction companies to plan, organize, and regulate their budget, therefore enabling them to deliver projects within the allocated finances. The budget analysis also helps in future forecasting and strategic planning, thereby enhancing profitability and competitiveness in the industry.
