# ProofLog > ProofLog is a QR-based service history and intervention verification platform for service companies, maintenance teams, technicians, facility managers, and equipment owners. ProofLog connects each physical asset or piece of equipment to a digital service history through a QR code. Authorized users can record interventions, photos, documents, checklists, customer signatures, server-recorded time, and optional location validation. Asset owners can review maintenance history, manage service requests, assign work to technicians, and create controlled before-and-after comparisons. ## Core purpose ProofLog helps organizations keep a clear, searchable, and verifiable record of work performed on equipment. It replaces fragmented paper logs, mobile photo galleries, spreadsheets, and chat histories with records organized around the asset itself. ## Main capabilities - QR identification and fast asset access - Service and intervention history for each asset - Service reports with notes, photos, videos, documents, and checklists - Customer signatures on service reports when enabled - Server-recorded timestamps and optional location validation - Before-and-after service documentation and secure read-only sharing - Service requests submitted by QR code - Technician accounts with scoped permissions and assigned assets - Maintenance reminders, dashboards, audit information, and report exports - Memo QR stickers and durable Hard QR stickers for physical equipment ## Intended users - Service and maintenance companies - Facility management teams - HVAC and boiler maintenance providers - Industrial maintenance providers - Fire protection, elevator, solar, medical equipment, vehicle, and machinery service teams - Organizations that need an accessible maintenance history and evidence of completed interventions ## Important product definition ProofLog is a service documentation and intervention verification SaaS. It supports operational traceability and evidence collection, but it does not independently guarantee regulatory or legal compliance.
