For General Contractors
Run your own audit before the owner's rep runs theirs.
XOPON audits your G702/G703 pay application before you submit it. Catch math errors, documentation gaps, and sequencing flags before they become rejected pay apps and payment disputes.
The owner's rep is running a review before they certify your pay app. The lender is running their own check before they fund. If your numbers are wrong — or your documentation is thin — payment gets delayed, disputed, or rejected. XOPON gives you the same audit they're running, before you submit.
What XOPON catches before you submit
Your retainage math is right
Wrong retainage percentages mean you leave money in holdback that you're entitled to. XOPON recalculates every line.
Your stored materials are documented
Undocumented stored materials get rejected or held. XOPON flags every claim that needs backup before you submit.
Your sequencing makes sense
Claiming MEP at 80% when structural is at 30% is a red flag that stalls approval. XOPON checks physical sequence logic.
Your schedule of values adds up
Arithmetic errors on the G703 are the fastest way to lose credibility with an owner's rep or lender. XOPON catches every one.
Your previous billing reconciles
Discrepancies between this pay app and what was previously certified trigger disputes. XOPON reconciles the numbers before you submit.
How it works
01
Paste your G703
Copy your schedule of values from Excel, your project management software, or a PDF. XOPON parses any format.
02
Get the audit in 60 seconds
XOPON runs 12 checks including math verification, retainage recalculation, sequence analysis, and documentation flags.
03
Fix it before you submit
Every finding tells you exactly what to correct, what documentation to attach, and what the dollar impact is. Submit with confidence.
$299 vs. a rejected pay app.
A rejected pay application delays your cash flow by 30 days minimum. A dispute over retainage math can stretch to 90. A full billing dispute can hold up project completion.
The full XOPON report costs $299. It shows you every error in your pay app before the owner's rep or lender finds it for you.
