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.

What is a Bond Claim?
A bond claim is a legal demand made against a construction bond to recover unpaid amounts owed by a contractor or project owner. Construction bonds are financial guarantees that protect project owners and subcontractors from financial loss if the prime contractor fails to meet their contractual obligations. When payment or performance issues arise, affected parties can file a bond claim to seek compensation from the bonding company.
There are several types of construction bonds, including payment bonds (which guarantee subcontractors and suppliers will be paid) and performance bonds (which ensure project completion).
For subcontractors, bond claims serve as an important safety net when general contractors fail to pay for completed work. Filing a bond claim can be complex and time-sensitive, often requiring specific documentation and adherence to strict deadlines. However, it provides subcontractors with a path to recovery when traditional collection methods fail, helping protect their business’s bottom line.
Siteline helps protect your bottom line too by streamlining billing processes and providing clear visibility into payment statuses, so you can identify and address collection issues before they require legal action. Learn more about Siteline here.
What is a Final Lien Waiver?
A final lien waiver is a legal document that serves as a formal release of a contractor’s or subcontractor’s rights to file a lien against a property owner or project after they’ve received full payment for their work. Its primary purpose is to provide assurance to the property owner, developer, and/or GC that no future claims or liens will be filed once the final payment has been made.
In the construction industry, subcontractors and material suppliers have the legal right to file a lien against a property if they have not been paid for their services or materials supplied. This lien acts as a security interest in the property, preventing the owner from selling or refinancing until the debt is settled. By signing a final lien waiver, the subcontractor or supplier acknowledges that they have received full payment and relinquishes the right to file a lien in the future.
For subcontracting businesses, obtaining final lien waivers from their lower-tier subcontractors and suppliers is crucial for these same reasons. It protects them from potential claims or liens that could arise after they’ve paid their lower-tier subcontractors in full. Failure to secure these lien waivers can expose subcontractors to legal and financial risks, as they may be held responsible for any unpaid debts owed to their lower-tier subcontractors or suppliers.
Overall, final lien waivers provide essential protection and peace of mind for all parties involved in a construction project, ensuring that all work has been satisfactorily compensated and preventing future disputes over payment.
Solutions like Siteline streamline the lien waiver process for subcontractors by:
- Automating collection from lower-tier subcontractors and suppliers;
- Providing a centralized view of lien waiver statuses across all projects; and
- Generating lien waivers (conditional or unconditional, progress or final) to submit to general contractors.
As such, Siteline helps enhance efficiency, mitigate risks, and enables subcontractors to focus on core operations while ensuring compliance and protecting against potential legal or financial complications that could arise from incomplete or missing lien waivers.

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.
