Pricing (as publicly stated)Basic free forever (limited work orders with attached procedures and repeating work orders). Essential $20/user/month billed annually ($25 monthly). Premium $65/user/month billed annually ($75 monthly). Enterprise custom pricing. Requester accounts free. Correction: our Oct 15, 2026 note recorded Premium and Enterprise as quote/sales, which was wrong for Premium (an archived Sept 22, 2026 copy of the pricing page already lists it at $65 annual / $75 monthly); only Enterprise is custom (Premium adds unlimited work orders with attached procedures, analytics, meter-based maintenance, parts/PO, REST API; Enterprise adds multi-site, SSO, IoT, MaintainX Assist). Re-checked Oct 17, 2026: the pricing page lists Premium at $65 per user/month billed annually ($75 billed monthly), with unlimited work orders with attached procedures, unlimited Advanced Analytics, meter-based maintenance, purchase order management and open REST API access; Enterprise is "Custom pricing" (adds IoT sensor integrations, SSO, multi-site tools, Global Procedures, MaintainX Assist, Asset Health Insights and Resource Planning).

Where the vendor descriptions differ

  • Not like-for-like: MaintainX is a system of record for maintenance work. Willow sits above building systems as an AI layer that diagnoses live conditions and acts on them; its homepage says its agents route work orders with supporting context, but the pages we read do not say which CMMS products it routes to.
  • Maintenance work: MaintainX lists work orders across sites, preventive and condition-based maintenance, parts inventory with low-stock alerts and automated re-orders, checklists and inspections, asset management, field service and an integrations marketplace. Willow lists Functional Testing within diagnostic and preventive maintenance workflows and tracking conditions after an intervention.
  • AI: MaintainX describes AI that turns manuals, procedures and work history into troubleshooting recommendations, AI-assisted summaries, natural-language reporting, anomaly detection, work-time estimates and predicted part needs. Willow describes insights prioritized by cost, energy, comfort and risk, Willow Copilot for questions about assets, spaces, live conditions and work history, agents for multi-step workflows, and Active Control with defined permissions, visible actions and operator overrides. AI tag: MaintainX is tagged AI features added to an established product; Willow is tagged AI-first.
  • Data: Willow is built on a buildings knowledge graph and digital twin that connect equipment, spaces, systems and live data. MaintainX lists industrial controls and IoT for collecting real-time asset data.
  • Who it's for: MaintainX's industry menu leads with manufacturing and also lists facility management, property management, government, retail and others. Willow names higher education, healthcare, retail and aviation, with solution pages for education, airports and healthcare.
  • Ownership and security: MaintainX's homepage says it joins Autodesk and lists SOC 2 Type 2, ISO/IEC 27001:2022 and GDPR. Willow names Microsoft, Carahsoft (public sector) and HPE as partners.
  • Pricing (checked Oct 29, 2026): MaintainX lists Basic free, Essential $20 per user/month billed annually ($25 monthly), Premium $65 billed annually ($75 monthly) and Enterprise custom, with free requester accounts. Willow shows no pricing link and offers Get a demo. See each tool page for detail.
  • Not used here: MaintainX's company count and case-study percentages, and Willow's cost, downtime and carbon figures and customer stories (vendor material). Neither tool has been tested by Means & Methods Lab.

Questions to ask in your review

  • Whether Willow can route work orders into MaintainX, and what that takes
  • What building data Willow needs before its AI is useful in an older building
  • What each costs for one building versus a portfolio
  • What did you use it for, on what kind of work and project size?
  • How long did setup and training take, and who on your team did it?
  • What does it cost you in practice, compared with what the sales call said?
