How to Automate AIA Billing in NetSuite: A Step-by-Step Guide for Construction Companies

If you've ever spent a week chasing down completion percentages from project managers, reconciling a Schedule of Values against change orders in a spreadsheet, and then manually assembling G702 and G703 documents for a pay application, you already know the problem. AIA billing is one of those processes that's straightforward in theory and brutal in practice.

Here's the uncomfortable truth most construction firms don't want to hear: the billing process itself isn't broken. What's broken is the infrastructure around it. When your estimate lives in one spreadsheet, your change orders in another, your Schedule of Values in a third, and your actual cost data in your ERP, the monthly pay application becomes a manual reconciliation exercise. Every month. And every month, it takes longer than it should and carries more risk than you'd like.

This guide walks through how AIA billing actually works, where construction firms typically lose time and accuracy, and how to set up a workflow inside Oracle NetSuite that eliminates the manual assembly. We'll also be transparent about where FullClarity fits into the picture.

What AIA billing is (and why it exists)

AIA billing is the standard billing format used across commercial construction in the US. It's named after the American Institute of Architects, which created the standardized forms that most general contractors, subcontractors, and owners use to request and approve progress payments.

The format exists for a good reason: it creates a consistent, auditable structure for billing on long-duration projects where work is completed incrementally. Instead of sending a simple invoice that says "pay us $200,000 this month," AIA billing documents exactly what percentage of each line item has been completed, what's been billed previously, what's being billed now, and what's left. That transparency protects both sides.

The two documents at the center of every AIA pay application are the G702 and the G703.

The two key documents: G702 and G703

G702: Application and Certificate for Payment

The G702 is the summary sheet. It shows the total contract value, the total completed and stored to date, the retainage withheld, the previous payments, and the current amount due. Think of it as the cover page that tells the owner or GC how much you're requesting and why.

G703: Continuation Sheet

The G703 is where the detail lives. It's the Schedule of Values broken down line by line, showing each item of work, its scheduled value, the work completed from previous periods, the work completed this period, the total completed and stored to date, the percentage complete, and the balance to finish. The G703 is the backup that substantiates everything on the G702.

Together, these two documents form the pay application. They're straightforward when a project is small and the scope hasn't changed. They get complicated fast when you're dealing with multiple change orders, retainage at different rates, and a Schedule of Values with 50 or 100 line items.

Where AIA billing goes wrong

Most of the problems with AIA billing aren't conceptual. They're operational. Here are the ones that come up repeatedly.

Manual data assembly. The biggest time sink is pulling data from multiple sources. The original contract value is in one place. Change orders are tracked separately (sometimes by different people). Completion percentages come from project managers via email or a shared spreadsheet that may or may not be current. Previous billing amounts need to be pulled from accounting. Putting all of that together into an accurate G702/G703 is a manual assembly job, and it typically takes days, not hours.

Change order confusion. Every approved change order modifies the contract value, which means it modifies the Schedule of Values, which means it modifies every subsequent G703. When change orders are tracked outside the billing system, there's always a risk that one gets missed or double-counted. That risk compounds month over month.

Overbilling and underbilling risk. Overbilling (billing for more work than has been completed) and underbilling (billing for less) are both problems. Overbilling creates legal and contractual exposure. Underbilling delays cash flow. Both are usually the result of stale completion data or misaligned Schedules of Values, and both are avoidable with better connected data.

Delayed cash flow. When the billing process is slow because it's manual, pay applications go out late. Late pay applications mean late payments. In an industry where cash flow is already tight, losing a week or two on every billing cycle has a real cost. In the US, more than 63% of firms reported that a project was postponed, scaled back, or cancelled in the past six months. (Sage/AGC, 2026 Construction Hiring and Business Outlook) Cash flow discipline matters more now than it has in years.

How NetSuite + FullClarity automates AIA billing

We'll be transparent: FullClarity is our product. What follows describes our workflow, and you should evaluate it with that context. That said, the best way we can earn your trust is to give you enough specific detail to verify everything independently.

FullClarity is built inside NetSuite and extends it with construction-specific workflows, including a complete AIA billing process. Here's how it actually works.

Step 1: Build the estimate. Every project starts with a Sales Estimate inside NetSuite. This is a spreadsheet-style worksheet where you build out the cost structure by category: concrete, framing, electrical, plumbing, whatever applies to your project. The estimate includes quantities, rates, amounts, contingency, margin, and sale price. This estimate becomes the financial foundation for everything that follows.

Step 2: Create the contract and Schedule of Values. Once the estimate is approved, you create a Contract directly from the project record. The contract pulls from the estimate data and generates a Schedule of Values (SOV), which is the line-by-line breakdown that defines what can be billed. This SOV is the basis for every future G703. Because it's built from the estimate, there's no manual re-entry.

Step 3: Process change orders. When scope changes, the change order is processed inside the same system. It updates the contract value, adjusts the Schedule of Values, and flows through to billing automatically. There's no separate spreadsheet to reconcile. The next time you generate a pay application, the change order is already reflected.

Step 4: Monthly progress claims. Each month, the project manager reviews each SOV line and records a cumulative completion percentage. FullClarity calculates the current month's claim automatically: the difference between what the new completion percentage implies and what has already been billed. For example, if a $50,000 SOV line is at 60% completion and $10,000 has been previously billed, the system generates a $20,000 claim for the current period. No manual math. No reconciliation against prior months.

Step 5: Generate AIA documents. The system produces G702 and G703 documents directly from NetSuite. These are formatted PDF outputs that match the standard AIA layout. Retainage is calculated automatically based on the rates configured in the contract. The documents are linked back to the project, the contract, and the underlying transactions, creating a complete audit trail.

The entire workflow, from estimate to contract to monthly billing, runs inside NetSuite. There are no external spreadsheets, no data exports, and no manual assembly of billing documents.

Real results from construction firms

The difference this makes shows up most clearly in time savings and error reduction.

Claremont Homes is a residential developer running a multi-entity model. Before NetSuite + FullClarity, their loan draw processing took roughly 40 hours per cycle. After implementation, that dropped to 4 hours. Project setup went from two weeks to one to two hours. (FullClarity, Claremont Homes Case Study)

Rendition Homes replaced 12 pre-construction spreadsheets with a single unified system. Their Operations Manager noted that "the system automates so much of what was manual before. Our staff quickly embraced it once they saw how much simpler their jobs became." Project setup time fell from two weeks to one to two hours. (FullClarity, Rendition Homes Case Study)

These aren't theoretical projections. They're published outcomes from firms that were dealing with the same manual billing processes most construction companies are running today.

Getting started with AIA billing automation

If you're running NetSuite and want to move from manual AIA billing to an automated workflow, here's a practical starting point.

1. Audit your current process. Before you change anything, map out exactly how your billing cycle works today. How many handoffs are involved? Where does data live? How long does a pay application take from start to finish? You can't improve what you haven't measured.

2. Clean up your Schedule of Values. If your SOV structure is inconsistent across projects, standardize it. Automation works best when there's a consistent framework to build on.

3. Get your change order process under control. If change orders are being tracked informally (email threads, side conversations, sticky notes on a whiteboard), formalize them first. The billing system can only be as accurate as the data feeding it.

4. Evaluate your options. If you're already on NetSuite, look at what's available in the SuiteApp.com marketplace. Construction for NetSuite covers AIA billing as part of a broader construction financial management workflow. If you're not yet on NetSuite, consider whether it's the right ERP foundation for your firm. As the world's leading cloud ERP, NetSuite gives construction firms a single platform for financials, procurement, and reporting, with the ability to extend it with industry-specific tools like AIA billing.

5. Plan the implementation carefully. A great product poorly implemented is worse than a decent product well implemented. Ask about implementation timelines, who handles the setup, and what ongoing support looks like. Talk to reference customers. Ask them what went differently than expected.

Honest advice: fix your processes before you buy software. If your completion percentages are unreliable, if your change order tracking is informal, if your SOV structures are inconsistent across projects, automation will speed up a broken process. Get the foundation right first.

Why NetSuite is the right foundation

It's worth noting why NetSuite works so well as the platform for construction billing automation. As the world's leading cloud ERP, NetSuite gives construction firms a unified system for financials, accounts payable, accounts receivable, procurement, and reporting. All of that data is already in one place.

When you extend NetSuite with construction-specific workflows like AIA billing, retainage, and job costing, the billing data connects directly to the general ledger, the project record, and the cost structure. There's no sync delay, no duplicate entry, and no reconciliation between systems. That's the advantage of working inside the platform rather than alongside it.

For firms currently assembling pay applications from data scattered across spreadsheets and disconnected systems, moving to NetSuite with Construction for NetSuite is often the step that makes real-time, accurate billing possible for the first time.

Frequently Asked Questions

Can you do AIA billing in NetSuite?

NetSuite provides a strong ERP foundation for construction firms, but AIA-specific billing — G702/G703 document generation, Schedule of Values management, and cumulative progress billing — requires extending the platform with a construction-specific SuiteApp. Construction for NetSuite by FullClarity adds AIA billing directly inside NetSuite, including automated claim calculations, change order integration, and formatted G702/G703 output.

What are the G702 and G703 forms?

The G702 (Application and Certificate for Payment) is the summary document showing the total contract value, work completed to date, retainage withheld, and the current payment amount requested. The G703 (Continuation Sheet) is the detailed Schedule of Values showing each line item, its scheduled value, prior billing, current billing, and percentage complete. Together, they form the standard AIA pay application used in US commercial construction.

How does FullClarity handle change orders in AIA billing?

When a change order is approved in FullClarity, it automatically updates the contract value and the Schedule of Values. The next pay application reflects the change without manual recalculation. This eliminates the risk of missed or double-counted change orders that's common when billing and change management live in separate systems.

How long does it take to set up AIA billing in NetSuite with FullClarity?

Implementation timelines depend on project complexity, the number of entities, and data migration requirements. Claremont Homes reduced project setup from two weeks to one to two hours after implementation. The broader system implementation for a mid-market construction firm typically takes three to six months, with AIA billing configuration as part of the overall construction workflow setup.

Do I need to fix my processes before automating AIA billing?

Honestly, yes. If your completion percentages are unreliable, your change orders are tracked informally, or your Schedule of Values structures are inconsistent across projects, automation will speed up a broken process. The firms that get the best results from billing automation are the ones that standardize their workflows first, then automate.
