Pay application software for general contractors: extract-and-verify vs create-and-submit
The short answer: pay application software splits into three categories, and only one is built for the party receiving the documents. Create-and-submit billing networks such as GCPay, Textura, Siteline, and Procore Pay run the subcontractor’s billing workflow and require both parties on the platform. Extract-only document tools, generic OCR and PDF converters, turn a pay app into a spreadsheet and never check a number. Extract-and-verify software, which is what pay application review software means, reads the inbound G702 and G703 and recomputes the arithmetic: on every line G = D + E + F, the sum of Column G must equal G702 Line 4, Line 3 = Line 1 + Line 2, Line 6 = Line 4 - Line 5, and Line 8 = Line 6 - Line 7. If your subs are not all on one billing platform, and almost no one’s are, the third category is the one that checks the math before you certify it.
What does “pay application software” actually mean?
The phrase covers three different products, and search results mix them together freely. Which one you need depends entirely on which side of the document you sit on.
Create-and-submit billing networks. GCPay, Textura, Siteline, and Procore Pay exist so a subcontractor can build a G702/G703 inside the platform, attach lien waivers, and submit up the chain while the GC approves and pays in the same system. They are genuinely good at this. Because the platform generates the form, the arithmetic is controlled at the source and the approval trail is clean. The structural requirement is that both parties are on the network: the sub bills through it, the GC receives through it, and a sub who never onboards is invisible to it.
Extract-only document tools. Generic OCR services and PDF-to-Excel converters take any document and return cells. They do not know what a G703 is, so a misread digit, and OCR misreads digits, lands in your spreadsheet with no warning. Converting is a real need, and the guide on how to convert a PDF pay application to Excel covers doing it well, but conversion is where these tools stop.
Extract-and-verify software. This is the category “pay application review software” names, and it is the receiver’s side of the workflow. It reads an inbound pay application in whatever form it arrives, native PDF, Excel, or scan, maps it to the G702/G703 structure, then recomputes every arithmetic identity the forms are built on and flags each mismatch with the expected figure and the dollar delta. PayAppCheck is this category. Nothing is auto-corrected without a human confirming it, and the result exports to Excel, CSV, and JSON.
The three categories side by side
| Billing networks (GCPay, Textura, Siteline, Procore Pay) | Extract-only tools (generic OCR, PDF converters) | Extract-and-verify (PayAppCheck) | |
|---|---|---|---|
| Who uses it | The sub and the GC together, on shared projects | Anyone with a PDF and a deadline | The receiver alone: GC, owner, lender, or bookkeeper |
| Do subs have to onboard? | Yes. Every sub bills through the platform, and adoption is the hard part | No | No. Subs keep sending whatever they already send |
| Inbound math errors | Prevented for in-network billing, because the platform computes the form; off-platform documents are out of scope | Passed through silently, including errors the OCR itself introduced | Recomputed and flagged with the expected figure and the dollar delta |
| Pricing shape | Per seat or per project, annual contract, sales-led | Per page or free, general purpose | Per document, self-serve (plans and pricing) |
| Export targets | Its own dashboards plus ERP integrations | A raw spreadsheet | Excel, CSV, JSON, and the developer API |
To be fair to the incumbents: this is not a ranking. A billing network on a project where every sub complies is the strongest control there is, because bad math never gets written down in the first place. The comparison exists because that condition fails on most projects. Subs on official AIA forms, subs on their own “G702-style” spreadsheets, scans, and faxes all arrive outside any network, and the receiving side still has to verify them before certifying payment. The categories are complements, not substitutes: many receivers run a network for their largest subs and review software for the inbound remainder.
How to choose, by role
General contractors. If you can mandate one billing network across every sub on every project, and they all comply, the network controls the math at the source and you need nothing else for those subs. The stack that arrives outside it, and on most jobs that is the majority, needs extract-and-verify. The full pre-certification sequence is in the review checklist.
Owners. An owner receives one application from the GC that rolls up everything beneath it, and has no lever to force anyone onto a platform. What an owner can verify is the rollup itself: the sum of Column C must equal Line 3, the sum of Column G must equal Line 4, and Line 7 must equal the prior application’s Line 6. Review software runs those checks on the single monthly document in minutes.
Lenders. A construction lender receives draw packages in whatever format each borrower’s GC produces, across many borrowers at once. The questions that matter before funding are whether the draw ties, whether retainage was taken at the contract rate, and whether Line 9 = Line 3 - Line 6 leaves enough balance to finish the work. Per-document review software answers them without asking any borrower to change tools.
Construction bookkeepers and accountants. A bookkeeper needs the numbers inside the accounting system, and needs them correct, because a wrong figure posted this month is a reconciliation problem next month. Extract-only tools get numbers in; extract-and-verify gets them in checked. Per-document pricing also fits a practice whose volume spikes around each billing cycle rather than sitting flat all year.
What does pay application review software have to prove?
Review software earns the name by recomputing the identities the two forms are built on. Each is one sentence, and each is a hard pass or fail:
- On every G703 line, total completed and stored to date is G = D + E + F.
- Percent complete is H = G / C, and a line over 100 percent is billed beyond its scheduled value.
- Balance to finish is I = C - G on every line.
- The sum of Column C must equal G702 Line 3, and Line 3 = Line 1 + Line 2.
- The sum of Column G must equal G702 Line 4; when it does not, work through what to do when a G703 does not match the G702.
- Retainage is 5a = rate × completed work and 5b = rate × stored material, and Line 5 = 5a + 5b.
- Line 6 = Line 4 - Line 5, Line 7 = the prior application’s Line 6, Line 8 = Line 6 - Line 7, and Line 9 = Line 3 - Line 6.
A tool that extracts these numbers without recomputing these identities is a converter. A platform that never sees the document because the sub is off-network is a billing system. Review software is the thing that takes the document you actually received and proves whether it ties.
Questions people ask
No. PayAppCheck works on the documents you already receive, in the form they arrive: native PDFs, Excel workbooks, and scans. That is the structural difference from billing networks such as GCPay or Textura, which verify billing by controlling it at the source and therefore need every sub onboarded. Extract-and-verify software only needs the receiver.
No. It sits in front of the accounting system and cleans what goes in. The review step extracts the G702 and G703 figures, checks the arithmetic, and exports Excel, CSV, or JSON that your ERP or accounting package imports. Posting, job costing, and payment stay where they are now.
The arithmetic the forms are built on. Per line it recomputes G = D + E + F, H = G / C, and I = C - G; across the forms it confirms the sum of Column C equals Line 3, the sum of Column G equals Line 4, retainage follows Line 5 = 5a + 5b, and the payment chain holds through Line 8 = Line 6 - Line 7. It also compares this application to last month’s, so Line 7 must equal the prior Line 6 and Column D must equal the prior D + E per line.
Yes. Scanned and photographed pay applications are read with a vision model, and every extracted number then passes through the same deterministic checks as a native file. The redundancy in the forms means a misread digit breaks an identity and gets flagged rather than slipping through, and a human confirms every correction before anything is exported.
The pricing shapes differ more than the amounts. Billing networks price per seat or per project on annual contracts, because both parties use them all year. PayAppCheck prices per document on self-serve plans, so a receiver pays for the stack actually reviewed each month.
