How to Extract AIA G702 Payment Application Data
to a Spreadsheet Automatically
The AIA G702 Application and Certificate for Payment and its companion G703 Continuation Sheet are the standard billing documents on virtually every commercial construction project in the United States. A mid-size general contractor managing five active projects receives roughly 10 to 15 payment applications per month from subcontractors. Each application includes a G702 summary page and a G703 continuation sheet listing 20 to 50 line items — every line item containing ten columns of cumulative and period-specific values. That's 200 to 750 values to verify per application, and 2,000 to 7,500 values per month across all projects. Every one of those numbers is either typed manually into a payment tracking spreadsheet, or transcribed from one spreadsheet into another. The form is standard. The data entry is not.
Key Takeaways
- The AIA G702/G703 is the most standardized form in US construction, yet mid-size GCs manually re-type 2,000 to 7,500 payment application values every month — numbers that get entered into three separate systems by three different people.
- Template extraction — the obvious fix for standard forms — breaks on G702/G703 not because forms vary, but because the same standard form gets filled by different PDF editors, contains wildly different line item counts, and is often submitted as handwritten scans that defeat pixel-position matching.
- Column-name extraction reads fields by meaning instead of position, letting ImageToTable.ai capture all 300 values per application across both the G702 summary and G703 line items in one pass — turning a 45-minute review into roughly 30 seconds of extraction plus 9 minutes of actual verification work.
The G702/G703 Billing Cycle: Same Numbers, Multiple Keyboards
The payment application workflow on a standard AIA contract project follows a predictable path: a subcontractor fills out the G703 Continuation Sheet — listing every line item from the schedule of values, entering the value of work completed this period, materials stored on site, and the cumulative total to date. The G702 summary page pulls forward the totals from the G703 and adds contract-level figures: the original contract sum, approved change orders, retainage withheld, and the net amount currently due.
The sub submits this package — typically as a PDF, sometimes as a printed form, occasionally as a filled Excel template — to the GC's project manager. The PM reviews the numbers for accuracy, checks that the G703 line item totals match the G702 summary figures, verifies retainage is calculated at the correct contractual rate, and then enters the approved values into the GC's payment tracking system. If the owner or architect requires their own review before certification, the data is entered a third time into the owner's system.
The same set of numbers — contract sum, change orders, work completed, materials stored, retainage held, amount due — is typed into three different systems by three different people. The G702/G703 format standardizes the presentation of the data but does nothing to reduce the number of times it gets manually transcribed.
A single payment application with 30 line items on the G703 contains roughly 300 individual numeric values across the ten columns. At 15 applications per month across five projects, a GC's project management team handles approximately 4,500 numbers per billing cycle — every one of which must be reviewed, and most of which must be typed into the GC's system for payment processing and project cost tracking.
The G702 and G703 are among the most standardized forms in construction. That standardization is exactly what makes them ideal candidates for automated data extraction — every field means the same thing on every form. The problem isn't format variety. It's volume.
Two Levels of Data: G702 Headers and G703 Line Items
Understanding the extraction requires understanding the two-tier structure of the payment application.
The G702 Application and Certificate for Payment is the summary. Its fields cover the contract-level financial picture:
Original Contract Sum | Net Change Orders | Contract Sum to Date
Total Completed & Stored to Date | Retainage % | Retainage Amount
Total Earned Less Retainage | Less Previous Certificates
Current Payment Due | Balance to Finish (including Retainage)The G703 Continuation Sheet is the detailed backup. Each row represents a line item from the project's schedule of values, and each column tracks a different aspect of that line item's financial progress. A single row contains:
Item No | Description | Scheduled Value
Work Completed: Previous Application | Work Completed: This Period
Materials Presently Stored | Total Completed & Stored to Date
% Complete | Balance to Finish | RetainageBoth levels must be extracted and cross-verified: the sum of all G703 line item "Total Completed & Stored to Date" values must equal the G702 "Total Completed & Stored to Date" on the summary page. The sum of all G703 "Work Completed This Period" values must equal the period's contribution to the G702 current payment calculation. Extraction that captures both levels in one pass eliminates the need to reconcile two separate data entry workflows.
Why Column-Name Extraction Handles G702/G703 Better Than a Template
At first glance, the G702/G703 seem like the ideal use case for template-based extraction. They're standard forms. The field positions are known. A template configured once should work forever.
In practice, three things undermine template reliability even on standard forms:
Fill-in displacement. When a subcontractor fills a G702 PDF electronically, the values they type often shift the pre-printed field labels slightly. A template expecting "Contract Sum to Date" at a fixed pixel coordinate will miss the value if the font size, line spacing, or field overflow moved it by even a few pixels. PDF fill-in tools from different software (Bluebeam, Adobe, browser-based editors) render filled values differently.
Variable line item count. A G703 sheet might contain 12 line items for one sub and 47 for another. A template that expects a fixed number of rows either misses data or captures empty cells as values. Column-name extraction reads the table dynamically — it finds all rows, regardless of count, and extracts every populated value.
Handwritten or scanned submissions. Smaller subcontractors still submit paper G702/G703 forms with handwritten or typewriter-filled values. A template expecting clean digital text fails on a scanned image. Column-name extraction works on scanned forms because the AI reads the visual content rather than relying on a digital text layer.
Column-name extraction handles all three cases because it searches for information by meaning rather than position. The field name "Total Completed & Stored to Date" tells the AI to find the cumulative dollar amount in the summary section of the G702. The field name "Work Completed This Period" tells the AI to find the current-period values in each row of the G703 line item table. The AI doesn't care whether the form was filled electronically or by hand, whether the line count is 12 or 47, or whether the font shifted the label by two pixels.

What the AI Extracts, and What the PM Still Verifies
An important distinction: the AI extracts the numbers from the form. It does not independently verify that the subcontractor's arithmetic is correct. The G703 line item values are the sub's reported numbers — the AI captures what the form says, whether or not the individual line items sum correctly to the G702 totals.
This means the project manager still owns two verification steps that no extraction tool should be trusted to perform:
Line item total reconciliation. The sum of all G703 "Work Completed This Period" values must equal the value used in the G702 current payment calculation. The AI provides both numbers. The PM confirms they match. When they don't — and subcontractor arithmetic errors are common — the discrepancy is flagged before payment processing.
Retainage calculation verification. Retainage is typically 5% or 10% of the completed work value, but the contractual rate can change at project milestones (often reducing to 50% of the original rate after 50% project completion). The AI extracts the retainage percentage as shown on the form. The PM verifies it matches the contract terms for the current project stage. This is a contractual judgment call, not a data extraction task.
The AI's role is to eliminate the typing — turning 300 numbers per application from manual entry into automated capture. The PM's role is to verify what matters — the reconciliation, the retainage calculation, and the approval decision. Together, the workflow reduces a 45-minute per-application review cycle to roughly 10 minutes: 30 seconds of extraction, 9 minutes of verification.
Frequently Asked Questions
Does this work with both digital PDFs and scanned paper G702/G703 forms?
Yes. Electronic PDFs with typed values produce the highest accuracy — near 99% for numeric fields. Scanned paper forms reduce accuracy proportionally to scan quality: a clean 300 DPI scan performs well; a low-resolution or skewed scan will produce more flagged fields. Handwritten values on scanned forms extract with lower confidence and require review. For best results, request electronic submissions whenever possible.
Can the AI handle G703 sheets with different numbers of line items from different subcontractors?
Yes. Column-name extraction reads the line item table dynamically — it finds all populated rows regardless of count. A G703 with 12 line items and a G703 with 47 line items process through the same field definitions and produce outputs with the same column structure. The row count adapts to each document automatically.
Does this integrate with Procore, Sage, or other construction management software?
The extraction outputs to Excel and CSV. Most construction management platforms — Procore, Sage 300 CRE, Viewpoint, Foundation, Jonas — accept Excel or CSV imports for payment application data. Export the extraction results and import into your platform. The data extraction step is independent of your construction management software; it feeds into whatever system you use for payment processing.
What about change orders on the G702 — can the AI distinguish original contract values from change order values?
Yes. The G702 has separate line items for the Original Contract Sum and Net Change Orders, leading to the Contract Sum to Date. Define separate columns for each, and the AI extracts them independently. The AI also captures change order line items that may be listed separately on the G703 if the sub has broken them out from the original schedule of values.
How many payment applications can I process in a single batch?
Upload an entire month's payment applications in one batch — 10 to 20 G702/G703 packages from multiple subcontractors. The AI processes each set independently, and the output merges all line items into a single spreadsheet with the subcontractor name and project reference repeated in each row for filtering and pivoting. The practical batch size depends on your plan tier rather than any technical restriction.
