Corrections and additions
This is a living census, not a closed report. If a company is missing, sits under the wrong service line, carries a verdict you can argue with, or has a better primary source, send it with a link. Useful for anyone who sees a gap in a service line they know, and for vendors who want the record accurate.
The calculator prices the lines marked replaced against your own revenue, in dollars.
