PayAppCheck - 2026 Pricing, Features, Reviews & Alternatives

PayAppCheck checks construction pay applications and tells you which numbers do not tie.

Dozens of tools help subcontractors create and submit AIA-style pay applications. Almost nothing serves the general contractor, owner, lender or construction bookkeeper on the receiving end, who opens a stack of inbound G702/G703 packets every month and has to verify each one by hand before money moves.

PayAppCheck reads a pay application in native PDF, Excel (.xlsx), or a custom G702-style layout, extracts every figure, and runs a deterministic reconciliation engine over the result. The G703 to G702 arithmetic is fully determined, so the math is not just output, it is the verification mechanism: it catches transcription and extraction errors and localizes them to a specific cell.

Checks include:

- Sum of Column G must equal G702 Line 4

- Column G must equal D plus E plus F on every line

- Line items must sum to the printed grand totals

- Completed and stored to date on a line cannot exceed that line's scheduled value, which surfaces over-billing

- Period-over-period carry-forward, which catches front-loading across billing cycles

- Retainage continuity month over month, including the separate 5a and 5b bases

- Cell-by-cell comparison of a resubmission against the prior version

- Lien waiver checks on amount, type, dates and signature

Every flag is reviewable and correctable in the browser next to the rendered source document. Nothing posts automatically. Export to Excel, CSV or JSON, or use the developer API.

There are also two free tools that need no account and no document to upload: a G702/G703 tie-out checker and a retainage calculator. You type the figures off the form and the same reconciliation engine that runs on uploaded pay applications checks them, so the free tool and the paid product return the same answer on the same figures. Nothing you type is stored.

PayAppCheck is in Early Access, so the whole product is free. No card and no trial clock. Pricing is set after Early Access.
