5 Best CMMS Software Tools with Spare Parts & MRO Inventory Management (2026 Review)

What is OEE-linked MRO inventory management?

OEE-linked MRO inventory management is a maintenance strategy where spare parts levels and reorder triggers are natively synchronized with real-time machine cycle counts and performance data to ensure critical components are available precisely when needed.

For Mike (the Tactical Manager), this is the end of the "Parts Hunt."

Instead of discovering an empty bin during an emergency breakdown, Fabrico identifies that a "Bad Actor" asset is approaching its failure threshold and ensures the part is staged and ready.

1. Fabrico: The Integrated System of Action

Fabrico is the only platform built to natively unify Native OEE pulses with a Field-Ready CMMS and inventory engine.

Why it wins for high-speed lines:
Fabrico treats inventory as an extension of the "Fault-to-Fix" cycle. When a technician scans a machine's QR Code, the system instantly shows the specific MRO parts required for that asset and their exact bin location.

Because it’s a System of Action, technicians can write off parts directly at the machine via the mobile app, even while offline. This real-time consumption tracking ensures your Maintenance Cost per Unit is always accurate and your "Value Fulcrum" is protected.

2. Fiix (by Rockwell Automation)

Fiix is a robust, enterprise-grade CMMS with deep capabilities in asset hierarchy and multi-site inventory standardization.

The Trade-off:
It is a "System of Record" designed for large procurement workflows. The implementation is often heavy, and the inventory module can feel overly administrative for technicians like Tom. In high-volume Plastics or FMCG plants, the lack of native, high-frequency PLC integration means reorder points are often based on the calendar rather than actual machine wear.

3. eMaint (by Fluke Reliability)

eMaint is a highly customizable EAM/CMMS that excels at tracking large volumes of parts across complex industrial environments.

The Trade-off:
Customization creates a "Complexity Tax." Many users find that eMaint requires significant IT overhead to maintain and lacks the "Field-Ready" simplicity of a native offline app. While it tracks inventory well for financial auditing, it often remains a "Data Silo" disconnected from the live production OEE.

4. MaintainX

MaintainX is widely praised for its intuitive mobile interface that makes parts consumption and simple inventory counts accessible for every operator.

The Trade-off:
It is a "Maintenance-First" tool. While it digitizes the stockroom brilliantly, it lacks the deep Visual RCA (Computer Vision) and OEE Performance tracking required to identify why specific parts are failing prematurely. It acts as a system of record for consumption but not an engine for predictive reliability.

5. UpKeep

UpKeep is a mobile-first CMMS known for its user-friendly inventory management and facility care modules.

The Trade-off:
UpKeep is designed for general asset maintenance rather than high-speed production reliability. It lacks the native maintenance-aware scheduling and the high-frequency connectivity needed to capture the Hidden Factory losses that drive parts consumption in a heavy manufacturing plant.

The Strategic ROI: Reclaiming Dead Capital

For Paula (the Strategic Leader), the business case for integrated inventory is built on "MRO Optimization."

By moving from a "Safety Stock" mindset to a Condition-Directed mindset, you eliminate the 15% of your inventory that is typically obsolete or overstocked. This reclaimed capital can be reinvested into high-impact optimizations like Inefficiencies Zoom-In.

As you build 12 months of clean consumption data, you are preparing your plant for the Fabrico Agent (AI Roadmap) to automate your entire MRO supply chain.

Stop stocking and praying. Start engineering your inventory with a System of Action.
