Cbiz, Inc.
A provider of accounting, tax, benefits, insurance, and business-advisory services to small and mid-sized companies across the US. It was founded in the 1990s as Century Business Services before shortening its name to CBIZ, a blend that stuck because the old name was a mouthful. The company grew by folding in dozens of local accounting and insurance firms under one umbrella, so a client's tax or benefits team often carries the CBIZ name today.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: -19.97M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
