How this service works
Read a construction pay application (AIA G702/G703, Procore, Textura) or change order PDF into structured figures, with arithmetic checks. $0.04 per page (up to 25 pages), quoted per document.
Output
A structured JSON object containing parsed financial figures from the pay application, including schedule of values line items, amounts completed to date, work completed this period, stored materials, retainage, contract amounts, and the net payment due — along with arithmetic check results flagging any discrepancies between line-level figures and stated totals.
Example use cases
Subcontractor invoice review workflow
“I just received a pay app PDF from our drywall subcontractor — it's an AIA G702/G703 — can you extract all the scheduled values, amounts completed this period, and the net payment due, and tell me if the math checks out?”
Change order PDF digitization
“Parse this change order PDF from our GC and give me the structured breakdown of the cost items and the total approved change order amount so I can enter it into our accounting system.”
Procore pay app audit
“Pull out all the line item figures from this Procore pay application PDF and verify the arithmetic — I want to know if the total billed matches the sum of the individual schedule of values rows before I approve it for payment.”
Technical details
Endpoint
POSThttps://subpay.ai/mcp?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically extract and validate financial data from construction pay application PDFs (AIA G702/G703, Procore, Textura) or change orders, especially when you need arithmetic verification rather than just raw text extraction. Prefer it over general-purpose PDF extractors when the document is specifically a construction billing document and you need structured schedule-of-values data with math validation.
Side effects
- Unreadable or scanned PDF with poor OCR quality may result in extraction errors or missing fields
- Unsupported pay application format not matching AIA G702/G703, Procore, or Textura templates
- Password-protected or encrypted PDFs cannot be parsed
- Heavily redacted documents may produce incomplete structured output
- Arithmetic checks may produce false positives on documents using rounding conventions
