Where every number comes from

Every rate carries

WD number · revision · modification date · SAM.gov deep link

If your rate is wrong, you eat the back wages. So every figure here shows you exactly which government record it came from.

Synced

August 29

DOL publishes modifications most Fridays. We diff every revision and flag what changed.

How we parse it

We skip what we can’t read — and log it.

A rate block we cannot parse is omitted and counted, not estimated. Our full method is public. Read the methodology

Stop retyping the WH-347

Certified payroll is due weekly on covered work, no-work weeks included. QuickBooks hands you a macro; the form still gets filled by hand. Here is the same Friday, done by the generator:

  1. Match the rate

    Type the classification. The current wage determination answers, with its provenance.

    Suggested from the current wage determination. Nothing is filled until you accept it. You are signing under 18 U.S.C. § 1001; confirm the classification and rate against your contract before you file.
