Best AIA Billing Software: Features, Tools, G702/G703 Automation, and Contractor Billing Guide
Choosing the best AIA billing software can make construction invoicing, payment applications, and financial management significantly easier. Contractors, subcontractors, and general contractors regularly handle complex billing processes involving progress payments, retainage, change orders, and project costs. Managing these activities manually can lead to calculation errors, delayed payments, and administrative problems.
AIA billing software helps automate these workflows by supporting standardized payment applications, including G702 and G703 forms. Whether you operate a small contracting business or manage multiple construction projects, selecting suitable software can improve financial accuracy, streamline approvals, and simplify payment tracking.
This guide explores essential AIA billing features, popular software solutions, integration options, and practical considerations for choosing the right platform.
What Is AIA Billing Software?
AIA billing software is a specialized financial tool designed to prepare, manage, and track construction payment applications using standardized American Institute of Architects (AIA) documents.
It helps construction businesses create payment requests, calculate completed work, track retainage, and manage financial documentation throughout a project’s lifecycle.
Common capabilities include:
- Generating G702 and G703 payment applications.
- Managing construction progress billing.
- Tracking completed work and stored materials.
- Calculating retainage and outstanding balances.
- Managing subcontractor invoices.
- Monitoring project costs and payments.
- Automating payment application approvals.
Understanding AIA Billing Forms
Two important documents are commonly used in construction payment applications.
AIA G702 Application and Certificate for Payment
The G702 billing software functionality helps contractors prepare the main payment application and certificate. It summarizes contract values, previous payments, completed work, retainage, and the current payment requested.
AIA G703 Continuation Sheet
G703 billing software functionality supports detailed breakdowns of project work through a schedule of values (SOV). It shows individual work items, scheduled values, completed work, stored materials, and remaining balances.
Together, these documents provide a structured approach to construction payment applications.
Key Features of the Best AIA Billing Software
The best AIA billing software for contractors should provide more than basic invoicing. It should support the entire construction billing workflow.
1. Automated Pay Applications
Automated pay applications reduce repetitive administrative work by generating payment documents using project information already stored in the system.
Contractors can review completed work, update billing amounts, and prepare payment requests without manually entering every calculation.
2. Retainage Tracking and Calculations
Retainage tracking helps businesses monitor the percentage of payments withheld until specific project milestones or contractual requirements are satisfied.
Accurate retainage calculations are important because incorrect deductions can create payment disputes and financial reporting problems.
3. Stored Materials Billing
Stored materials billing allows contractors to request payment for eligible materials purchased or stored for a construction project.
Software should support documentation and tracking to help verify these materials before submitting payment applications.
4. Change Order Management
Change order management helps contractors document modifications to project scope, pricing, and timelines.
Connecting approved change orders with payment applications keeps contract values and billing records consistent.
5. Lien Waiver Management
Lien waiver management organizes documents confirming payment-related rights and obligations. Digital workflows can help collect, review, and store lien waivers before releasing payments.
6. Construction Financial Management
Effective construction financial management requires visibility into accounts receivable, accounts payable, job costing, and project cost tracking.
A suitable platform should connect these activities to help businesses understand project profitability and cash flow.

How to Automate AIA Billing
Businesses can improve billing efficiency through a structured implementation process:

- Establish a schedule of values (SOV).
- Enter completed work and stored materials.
- Apply approved change orders.
- Review retainage calculations.
- Generate payment applications.
- Submit documents for approval.
- Track payments and outstanding balances.
How to Generate G702 and G703 Forms
Start by entering contract details and schedule-of-values information. Update completed work, previous payments, and eligible stored materials. Calculate retainage and the current payment due, then review the G702 and G703 documents before submission.
How Does AIA Progress Billing Work?
Construction progress billing allows contractors to request payments based on completed project work during a billing period. The contractor updates the schedule of values, calculates the amount earned, applies retainage, and submits the payment application for review.
What Is the Difference Between G702 and G703?
G702 summarizes the overall payment application, while G703 provides the detailed schedule-of-values breakdown supporting the requested payment.
How to Calculate Retainage in AIA Billing
Retainage is generally calculated by multiplying the applicable retainage percentage by the eligible amount of completed work, subject to contract terms and applicable adjustments.
How to Track Change Orders and Stored Materials
Use dedicated project records to document approved scope changes, material descriptions, costs, storage information, and supporting approvals. Connect these records with the relevant billing period.

Solutions such as Procore, Sage 300 CRE, FOUNDATION Software, GCPay, Oracle Textura, and Acumatica Construction Edition offer different approaches to construction financial management.
