A three-minute branching check against the official NAICS definitions — practices, DSOs, labs, staffing, suppliers, vendors — then a personalized filing kit: the exact field on every form you’re facing, an SBA size check run on your own receipts, and a paste-ready basis-for-classification memo for the audit file.
