Description

Stop paying per seat for maintenance software. A4B is a CMMS for small and mid-sized teams tired of enterprise pricing — one flat rate of $19.99/month for 50 users, free tier to start. Asset Management Every asset gets an auto-generated ID, searchable metadata (serial numbers, manufacturer, warranty dates), and custom fields. Workspaces separate sites or business units. CSV import handles migrations from spreadsheets or legacy systems. Every edit is versioned. Preventive Maintenance and Work Orders Schedule PMs on a cadence, raise reactive work orders when things break, assign priorities and owners, and let daily email reminders keep tasks from slipping. Export full history to CSV for auditors. QR Codes for the Shop Floor Print a QR label for every asset. A technician scans with whatever phone is in their pocket, the browser opens the asset page, and they log work without hunting for a desktop. No app, no MDM rollout. AI You Can Actually Use on Your Data A4B ships with a Model Context Protocol (MCP) server secured by OAuth 2.1 — the layer Claude, ChatGPT, Cursor, and Claude Code use to work with external systems. Ask what's overdue, draft a work order from a photo, or pull a report in plain English. Every tool call is audited. Capital Planning That Keeps Pace With Operations The Capital Overview dashboard tracks fleet book value, monthly depreciation, and the assets bleeding the most value — then rolls up a 12-month replacement forecast. Plan capital spend on the same calendar as your PM schedule instead of scrambling after a failure. Admin-only. - Free: 5 users, 50 assets, 2 workspaces - Premium: $19.99/month for 50 users, 500 assets, 5 workspaces For manufacturing, warehouses, facilities, schools, nonprofits, and multi-site operators.
