Tenon is construction management software for working contractors, bringing project and business workflows into one system. Its tools cover estimates, proposals, Gantt scheduling, daily logs, budgets, invoicing, change orders, RFIs, and client portals. Sage, the AI assistant, answers project questions, cites records, drafts change orders and proposals, and uses per-user permissions. Native iOS and Android apps provide field logs, timers, and RFIs; the iOS app also supports Apple Watch and CarPlay. Tenon lists QuickBooks sync for invoicing and an MCP integration for Claude.ai and other MCP clients. Field workers, subcontractors, and clients are free on every plan, while paid seats are for office users. Starter costs $49 a month billed per user and includes up to three Builder seats and unlimited Field seats; Pro is $129 a month billed per user, and Enterprise is $249 a month billed per user. There is no free plan, but a 30-day trial is offered. Customer data is stored in AWS Canada (ca-central-1); customers can export it to CSV, PDF, or JSON, and Tenon says it does not hold data after cancellation. SOC 2 Type II is in audit.
