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 WH-347?
WH-347 is a form utilized in the construction industry by contractors and subcontractors engaged in federal or federally-assisted construction contracts. This certified payroll form, issued by the U.S. Department of Labor, requires contractors to report detailed wage information for employees including hours worked, job classification, rates of pay, and deductions. The purpose of the WH-347 form is to ensure contractors are compliant with the Fair Labor Standards Act regulations. Witnessed and attested to by an assigned company official, this form plays a crucial role in the transparent and fair operation of the construction industry, ensuring that workers are compensated according to stipulated guidelines and in line with labor law regulations.
What is are costs in excess of billings?
Cost in excess of billings (CEB), or underbilling, refers to a cost incurred by a subcontractor for work performed that has yet to be billed to the general contractor at any point in time. This is a somewhat common scenario that can arise when the cost of work expenses (labor, materials, subcontractors, etc.) hit before billings go out.
There are a few factors that can create this timing gap and lead to underbilling. These include:
- Progressive billing schedules: Many construction projects have billing schedules that are based on predefined milestones or stages of completion. However, costs are being incurred continuously as work progresses. This causes costs to build up ahead of invoices between billing cycles.
- Upfront and early-stage mobilization: Significant upfront costs go into things like materials, equipment, permitting, and mobilizing job sites before physical work even begins—especially for subcontractors. These costs typically accumulate before clients are billed.
- Pending change orders: Costs related to change orders often hit weeks or months before details are finalized and approved for billing. Diligently tracking pending change orders is crucial to ensure you ultimately collect on all revenue owed from approved changes.
- Project delays: In construction, delays are inevitable. If and when delays push out project milestones, billable events can slide further out from when the costs were incurred. These timeline gaps widen the difference between accrued expenses and billings-to-date.
CEB is reflected on financial statements as assets because it represents an unbilled receivable for revenues that will later come. Therefore, regularly monitoring CEB is critical to maintaining healthy business operations as it helps subcontractor accounting teams:
- Understand true project economics: CEB helps reveal the full profitability picture by linking incurred costs with unbilled receivables, which in turn supports more accurate revenue forecasting and job costing projections.
- Gain greater cash flow visibility: Because CEB tracking shows how much money is flowing out that’s tied up in work completed but not yet paid for, it helps them better plan and manage their cash for future expenses.
- Monitor project health: Unexpected CEB spikes could signal problems like cost overruns. Regularly comparing CEB status with the original budget is key to assessing a project’s overall health.
- Collect revenue in full: No one wants to work for free. Tracking CEB ensures that all pending receivables are ultimately invoiced and collected.
- Stay compliant: CEB reporting is required for percentage-of-completion revenue recognition, which is an important accounting standard for billing teams to adhere to.
Effective CEB oversight is much simpler with the right tools in place. With Siteline, you can easily track costs in excess of billings on each project to ensure no completed work goes unbilled. Siteline monitors all pending change orders through a project's lifespan, too, helping teams get approval quicker and convert unbilled work into invoiced revenue.

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.
