AIA Billing
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.

What is ASC 606, Revenue from Contracts with Customers?
ASC 606, Revenue from Contracts with Customers, is an accounting standard that provides a comprehensive, industry-neutral revenue recognition model intended to increase financial statement comparability across companies and industries. For the construction industry, it has substantial implications as it changes how and when revenue from contracts is recognized. Under this model, construction companies recognize revenue by transferring promised goods or services to customers in an amount that reflects the consideration they expect to receive. ASC 606 can affect a construction company's financial statements, operations, and tax obligations. It demands that companies disclose more detailed revenue and contract information than before. Therefore, understanding ASC 606 is critical for construction industry stakeholders to assess a company's performance and future prospects accurately.
What is a Milestone?
A milestone in the construction industry refers to a significant event or achievement in the life of a project. It marks a turning point that indicates the completion of a major phase, or a key deliverable. For instance, it could be the conclusion of the design phase, acquiring a building permit, or completion of site excavation. These markers serve as checkpoints to monitor progress, assess risks and ensure that the project is on schedule. They function as tools for communication among stakeholders about the status of the project, providing a clear picture of the project's trajectory. Furthermore, milestones can also provide a basis for payment, wherein a contractor may be paid upon reaching specific milestones. In essence, milestones are pivotal in construction project management, underpinning successful planning, coordination, and execution of projects.
What is Depreciable Life?
Depreciable Life, in the context of the construction industry, refers to the estimated period during which a tangible asset like a building, machinery, or equipment used for construction purposes, can generate income before it becomes outdated or reaches the end of its useful economic life. The Internal Revenue Service (IRS) often stipulates the depreciable life of an asset, typically ranging from 15 to 39 years for commercial real estate. This expected lifespan is vital in determining depreciation rates for businesses to recover the cost of assets over time via tax deductions. It assists in shaping financial and investment decisions on repairs, replacements, and asset acquisitions in construction businesses.
