For the people who answer “which rates applied, and when?”
Certified payroll runs on wage determinations, but SAM.gov only shows you what's current. When a GC, agency, or auditor asks about rates from eight months ago, the document that governed has been superseded, sometimes twice. WagePin keeps the whole trail.
Every revision, archived permanently
We store every revision of every active determination we cover, including superseded annual decision numbers, with the full classification tables parsed out. The revision that applied to your project stays citable long after SAM.gov has moved on. Look any determination up by number from the home page, or find your county by name or ZIP.
Diffs between any two revisions
Pick any two revisions of a determination and see exactly which classifications changed rate or fringe, what was added, and what was removed, with cosmetic reformatting filtered out. When someone asks “did the plumber rate change mid-project?”, the answer is one link, not an afternoon of side-by-side PDFs.
Alerts when rates move
Watch a determination, or a whole county, from its page and get an email diff the night a substantive change publishes. No more discovering a modification at certified-payroll time, three weeks after it landed.
CSV exports
Every revision's classification table exports to CSV from its determination page, ready for your payroll system, rate sheets, or audit workpapers.
Estimating side of the house? WagePin also pins bids to the revision that governs them under FAR 22.404-6.
