In their own words
One by Lessen
One by Lessen manages property and facility maintenance from work order creation through vendor sourcing and invoicing. It is designed for owners and managers of large, distributed residential and commercial portfolios, as well as property managers, technicians, vendors, and portfolio owners. The client portal covers work orders, data insights, reporting, cost controls, asset inventory, compliance management, and open APIs. Vendor tools handle work orders and projects, proposals, invoices, communications, task priorities, and scorecards.
One Insite helps property managers assign, schedule, track, and optimize technician workflows, with rule- and capacity-based dispatch recommendations and lifecycle cost controls. One Onsite supports vendor jobs, routes, in-route notifications, and property and issue details. One Maintenance lets residents submit requests and receive updates on arrivals, status, and approvals. Commercial asset tools include QR code tagging, preventive maintenance, facility management, and inventory for repair-or-replace decisions. The product runs on web, Android, and iOS, with API access. Lessen says support is available 24/7 through the client portal, phone, or email. Pricing is paid and available on request; prospective customers are directed to contact sales for a demo.
