Primus Maintain is a maintenance management platform built for manufacturing facilities and field service teams that operate in safety-critical, regulated environments. Most CMMS tools record what happened. Primus Maintain prevents what shouldn't. LOCKOUT/TAGOUT ENFORCEMENT Multi-technician LOTO is enforced, not just logged. Work orders stay locked until every assigned technician verifies their lock. Primus structurally prevents non-compliance instead of documenting it after the fact. QR-GATED WORK ORDERS Technicians scan an equipment QR code to start work, confirming they are at the right asset before any task begins. No guesswork, no wrong-machine errors. PM EFFECTIVENESS SCORING Preventive maintenance is measured, not just scheduled. Track which PMs actually reduce failures, with accountability chains that show who did what and when. PROCURE-TO-PAY PARTS MANAGEMENT A full spare parts catalog with bin-level location addressing, QR-labeled parts crib, purchase requisitions, bill of materials linked to equipment, and automatic reorder alerts. WORKFORCE INTELLIGENCE See coverage gaps, PTO impact, and technician availability so maintenance work gets assigned to people who are actually there. SAFETY AND COMPLIANCE OSHA-aligned incident workflows and audit-ready records built for facilities where compliance is not optional. Primus Maintain manages machines, processes, and people together — operational intelligence for teams that can't afford to get safety wrong. Requesters are always free. Pay only for maintenance technicians and administrators.
