RevQR is a focused document control product for manufacturing teams that need the current approved work instruction available at point of use. It is designed for the ISO 9001 document-control problem: release the right revision, keep traceability around approval and effective dates, and show evidence without buying a broad QMS stack. Teams use RevQR for approval before publish, scheduled release by effective date, controlled register visibility, audit-ready evidence, and optional named acknowledgement where reader-level proof is required. RevQR is intentionally narrow: it is not a full QMS, not a PLM system, and not a training LMS.
