Revenue over time
Every filing period on record, as reported. One column per filed period — a period with no column is a period with no filing, not a zero.
Basis · Amendments and terminations supersede the original report for the same registrant, client and period, so a revised quarter is counted once at its latest filed value. Registration-only filings carry no activity money and are excluded from these totals.

The filings
The 20 most recent of 415 filings. Every figure above is built from these records.
This record groups every filed spelling of the registrant's name into one entity, so punctuation variants of the same firm read as one. The grouping is the registrant's normalized name — firms that file under genuinely different names appear separately. Handle: the-hamm-consulting-group-llc.
