What PayAppDelta does

PayAppDelta compares two consecutive monthly US construction pay application tables that you provide (last month’s approved document and this month’s draft) and lists differences: lines missing from either period, changed scheduled values, prior totals that differ from current previous billed amounts, cumulative arithmetic that does not add up, totals above scheduled values and repeated line or change order IDs. Lines match only on an exact normalized line ID; nothing is guessed. Amounts are US dollars only.

No guarantees; your responsibility

Results depend entirely on the documents you supply. PayAppDelta is not an approval, audit, legal, accounting or compliance review, does not reproduce or replace any official form, and does not guarantee that a document is correct or will be accepted. Spreadsheet formulas are not recalculated; cached values stored in the file are used. Check every finding against your own records before you act on it.

Pricing

The free tier compares up to 10 distinct lines with a basic CSV. Unlocking a comparison costs $49 USD, once, for that comparison ID only: every line, plus a detailed Excel report and PDF report with the exact source cells. There is no subscription and no expiry. A new comparison has a new ID and needs its own unlock. Payment is taken by Square or PayPal on their hosted pages.

Refunds

If something prevents an unlocked comparison from working as described, contact support and we will make it right or refund the purchase.

Your data

Your documents stay in your browser; see the privacy page. Keep your own copies: we cannot recover comparisons or purchase records removed from your browser.

Availability

The service is provided as is, without warranty, to the extent the law allows.
