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.

What is an Audit?
An audit, within the construction industry, is a systematic and independent examination of a project, contract, or business unit. It is a thorough and comprehensive assessment of a company's construction processes, internal controls, and business practices. This review is conducted to ascertain compliance with the set industry standards, regulations, as well as to verify the authenticity and legitimacy of financial statements. The audit ensures that every operation within the construction cycle, from procurement of materials to the completion of the building, is carried out accurately and fair. It helps a firm to understand the areas of inefficiency and mitigate any risks. Furthermore, an audit could provide opportunities for improvements, ensuring efficiency, productivity and profitability for construction businesses.
What is an Architect?
An architect is a professional who works within the construction industry and is responsible for designing and planning buildings and oversee their construction. They utilize their specialized skills in art, science, technology, and humanities to design safe and functional buildings, from residential homes to large commercial properties. Besides the aesthetic aspect, their work also involves understanding structural integrity, safety regulations, and building codes. The role extends beyond design, it includes meetings with clients, contractors, engineers, and other professionals. Their intricate hand in shaping environments makes them a vital cog in the construction industry.
What is AIA® billing?
AIA® billing is a standardized payment application process for construction projects. Developed by the American Institute of Architects (AIA®), it uses specific forms—primarily the G-702® Application and Certificate for Payment and G-703® Continuation Sheet—to document and request progress payments throughout a project. These forms create a uniform system for contractors that shows exactly what work has been completed, what materials have been stored, and what payment is due during each billing period. They also require detailed information about contract values, change orders, and retainage amounts. AIA® has become the industry standard, especially for larger commercial projects and government contracts.
For subcontractors, understanding AIA® billing is essential since most large general contractors (GCs) require these forms or customized versions of them. While AIA® billing can initially seem complex, it provides important benefits like reducing payment disputes, creating clear documentation of work progress, and often resulting in faster payments. Mastering AIA® billing opens doors to working with larger GCs and bidding on more substantial projects. That’s why we created this comprehensive guide, filled with detailed information on completing AIA® billing forms and managing the payment application process.
Siteline simplifies the AIA® billing process by automating form creation and submission. Our system currently maintains 15,000 custom billing forms from more than 10,000 GCs, enabling subcontractors to generate perfect pay apps in minutes for fewer delays and faster, more predictable payments.
