Automated AIA G702/G703 Application for Payment Preparation Workflow

Manual billing cycles typically take 5-10 days of project accounting labor each month, delaying invoice submission and payment receipt. This workflow automates data aggregation from ERP systems (Sage, CMiC, Viewpoint), timesheets, and material invoices to generate a complete, auditable G702/G703 application in hours. By submitting applications 1-2 weeks faster, you improve DSO and unlock working capital tied up in the billing cycle.

The core bottleneck is manually pulling data from fragmented systems—job cost reports, stored material tickets, subcontractor invoices—and transposing it into the standardized AIA forms. A custom workflow uses orchestrated agents (browser or API) to extract, validate, and map this data. For example, an agent queries the ERP for completed work values, another pulls lien waivers from a document management system, and a third validates totals against the schedule of values. This eliminates human error and frees project accountants for exception handling and analysis.

Inconsistent or poorly documented payment applications lead to owner queries, delayed approvals, and strained relationships. This workflow enforces business rules: it cross-references billed amounts against approved change orders, attaches mandatory backup documentation (like certified payrolls), and generates a complete audit trail. The output is a professional, consistent, and fully supported package that minimizes back-and-forth and strengthens your position during audits or claims.

As your project portfolio grows, manual billing becomes a scalability constraint, requiring more staff or leading to burnout and delays. This automated workflow acts as a force multiplier. One project accountant can oversee billing for 10x the projects because the system handles the repetitive assembly. The architecture is designed for multi-tenancy, allowing you to run parallel billing cycles for dozens of projects from a single orchestration layer, turning a fixed cost center into a variable, highly efficient operation.

Construction software stacks are fragmented; critical data often sits in legacy systems or web portals with no API. This workflow uses a hybrid integration architecture: browser automation (via Playwright or RPA) to log into and scrape data from vendor portals, combined with direct API calls to modern cloud ERPs. An orchestration framework like LangGraph manages the stateful workflow—triggering data collection, running validation rules, pausing for human review of exceptions, and finalizing the PDF package—creating a unified layer atop your disparate tech stack.

Deployment is not a "black box" replacement. A production-grade implementation includes configurable approval gates: a project manager reviews the calculated completed work value before submission, and the controller approves final release. The system provides a clear dashboard showing data sources, validation flags, and any missing documents. This controlled rollout minimizes risk, builds user trust, and ensures the workflow complements—rather than replaces—critical financial oversight.

The workflow's foundation is an orchestration layer that connects to disparate, often API-less systems. Browser-driven agents log into ERP portals (e.g., Sage, CMiC, Viewpoint) to extract job cost ledgers, approved invoices, and stored material reports. Concurrently, it ingests validated timesheet data from field apps and payroll systems. A normalization engine maps this fragmented data to the standardized line-item structure of the AIA G702 application, resolving discrepancies in cost codes, vendor names, and units of measure before calculation begins.

At the core of the workflow is a rules-based calculation agent that determines the value of work completed during the payment period. It applies contract-specific billing rules (e.g., percentage-of-completion, unit price) to the normalized cost and schedule data. The agent cross-references the schedule of values (G703) with actual progress, accounts for retainage, and calculates the current period's billing amount. This replaces error-prone manual spreadsheet calculations, ensuring mathematical accuracy and contract compliance.

A document generation agent populates the final G702/G703 PDF forms using the calculated values and ingested data. It then assembles the complete payment package by attaching the required supporting documentation: lien waivers for paid items, certified payroll reports (if applicable), and material invoices. The agent retrieves these documents from integrated document management systems (e.g., Procore, SharePoint) or vendor portals, creating a single, audit-ready submission package. This eliminates the manual hunt-and-peck process of compiling dozens of supporting files.

Before submission, the draft application and compiled package are routed through a configurable approval chain. Using a state machine (e.g., LangGraph), the workflow notifies the Project Manager, Controller, and Owner's Representative via their preferred channels (email, Slack, MS Teams). Approvers can review in a centralized dashboard; any line-item disputes or exceptions trigger a pause and route the package back to the project team with comments. Only fully approved packages proceed, creating a defensible audit trail for all financial decisions.

Upon final approval, a browser automation agent submits the complete package directly to the owner's designated portal or via email, handling login and form navigation where APIs don't exist. Simultaneously, the workflow updates the project's accounts receivable within the ERP system, flags the expected payment date based on contract terms, and triggers a reminder for follow-up if payment is delayed. This closes the loop between billing preparation and cash collection, directly improving working capital management.

The entire workflow is instrumented for observability. A monitoring dashboard tracks cycle times, exception rates, and data quality scores for each source system. Every data point used in the calculation, every approval action, and every submission attempt is logged to an immutable audit trail, essential for project audits or disputes. This data also feeds a retraining loop for the normalization and calculation agents, allowing the system to improve its handling of new contract types or unusual billing clauses over time.
