Guaranteed Maximum Price (GMP)

What is a Guaranteed Maximum Price (GMP)?

A guaranteed maximum price (GMP) is a financial cap used in construction contracts, representing the highest possible price a client can expect to pay for a particular project. This cap encompasses raw materials, labor, indirect costs, and a margin for the contractor’s profit. 

While offering financial predictability and safety to the client, this method can significantly impact subcontractors. To transfer a portion of the financial risk, general contractors (GCs) typically offer subcontractors fixed-price (or lump sum) subcontracts. This setup incentivizes subcontractors to adhere to budgets and timelines, as cost overruns directly affect their profit margins (unless the client was the one who requested changes). Conversely, if the project is completed under budget, subcontractors may benefit by sharing the savings with the GC. Ultimately, GMP contracts foster transparency and collaboration, promoting shared responsibility for project success between all parties involved. 

In GMP contracts where payments are tied to milestones or completion percentages, accurate pay applications—a core feature of Siteline—are crucial to getting paid sooner. Siteline also enables subcontractors to track outstanding balances and monitor their cash flow in real-time, empowering them with insights to proactively manage their financial health—which is paramount in GMP contracts.

Prime Contractor

What is a Prime Contractor?

A prime contractor, also commonly referred to as a general contractor, is the main contractor responsible for managing an entire construction project. They are in direct contact with the build’s owner/developer and hold primary responsibility for the construction, execution, quality, and completion of the project under the agreed terms and schedules. As such, the prime contractor addresses concerns and resolves issues related to the project, contributing to the effective execution and timely delivery. The prime contractor also manages the procurement of materials, labor, and equipment, ensuring compliance with building codes and regulations.

A critical part of the prime contractor’s job is hiring and managing trade contractors, also known as subcontractors, who specialize in specific construction trades like electrical, plumbing, framing, etc. The prime contractor essentially acts as a hub, contracting out portions of the work to skilled trade contractors while retaining overall control of the project operations.

Prime contractors have a vested interest in working with subcontractors who not only are highly skilled in their respective trades but also have efficient, well-defined operational and financial workflows to ensure reliability and consistency in their performance. Streamlined billing processes are crucial in this regard. When subcontractors can quickly and accurately generate pay applications—complete with the necessary compliance documentation and lien waivers—it allows the prime contractor to bill the project’s owner promptly and get paid faster. Delays in subcontractor billing can significantly impede the prime contractor’s ability to get paid in time, thereby causing delays in payments to other contractors, too. 

This is where a solution like Siteline can ultimately benefit prime contractors by helping their subcontractors streamline billing processes. Siteline accelerates subcontractor billing by automatically generating pay apps per prime contractor specifications, tracking compliance requirements, managing change orders and lien waivers, and providing payment visibility. When subcontractors use Siteline to automate billing, prime contractors receive accurate, compliant pay applications faster, allowing them to bill project owners promptly and get paid quicker as a result.

Unit Price Contract

What is a Unit Price Contract?

A unit price contract is a widely used pricing model in the construction industry where general contractors (GCs) provide a fixed price for each unit of work and material (based on the anticipated quantities specified by the client). The final contract amount is calculated by multiplying the pre-agree unit prices by the actual quantities used or work performed.

This approach allows for flexibility as the total costs adjust to reflect actual usage. Therefore, unit price contracts are ideal for projects with uncertain material and work quantities, helping avoid cost overruns due to miscalculations.

For subcontractors, there are specific considerations when working with unit price contracts. It’s crucial to ensure precise unit price calculations to maintain profitability and implement sound systems for tracking and reporting actual quantities. Clear communication with the GC about quantity changes is also important, and subcontractors should be prepared to justify any discrepancies that may occur.

Siteline—an intuitive A/R management system—simplifies unit price billing for subcontractors, allowing them to:

  • Easily input and update unit prices;
  • Automatically calculate billing amounts based on reported quantities; and
  • Generate accurate, detailed pay applications that show up-to-date unit prices and quantities.

Estimate

What is an Estimate?

An estimate in construction is a calculated projection of the costs, time, and resources required to complete a specific project or scope of work. It includes direct costs like labor, materials, and equipment, as well as indirect costs such as overhead, insurance, and profit margins. 

Construction estimates serve as the foundation for project planning, budgeting, and decision-making, helping both contractors and clients understand the financial commitment required. Estimates can range from rough preliminary assessments to detailed breakdowns that are often refined as project details become clearer or circumstances change.

Accurate estimating is essential for subcontractors to win profitable work while maintaining healthy margins. Many successful subcontractors develop standardized estimating processes that incorporate historical cost data, current market rates, and lessons learned from previous projects to improve bid accuracy and build credibility with general contractors.

Siteline helps you be strategic with how you bid, letting you easily analyze historic payment and project trends, including seeing your fastest- and slowest-paying clients. If you're curious how Sitleine can help you make calculated bids that will yield the fastest payments and improve overall cash flow, request a demo here.
