When a mid-sized company runs hundreds of assets across several sites (turbines, process lines, fleets, networks), the question is no longer “which CMMS should we buy?” It is “where does the truth about the asset live: in the ERP or in a specialist EAM tool?” Four names come up in nearly every shortlist: IFS Cloud, SAP S/4HANA, Infor EAM and IBM Maximo. This article compares them on criteria you can verify, and tells you which one to look at first for your profile.
Method: the functional capabilities below draw on vendor websites and documentation. Where a point could not be confirmed from a public source, we say so. No vendor performance figure is repeated without context: the “up to X%” gains in sales brochures are not comparable with one another.
CMMS vs EAM: where a CMMS stops
A CMMS (computerized maintenance management system) manages work orders, preventive maintenance and spare parts for a site. We covered it in our ERP and CMMS integration guide. EAM (Enterprise Asset Management) scales up on three points:
- The full asset lifecycle: design, commissioning, operation, renewal, decommissioning, with the associated capex logic.
- Multi-site operations: asset hierarchies, maintenance standards and master data shared across plants, networks or infrastructure portfolios.
- Risk and reliability management: criticality, reliability-centered maintenance (RCM), regulatory compliance, investment decisions.
If your assets amount to a few lines in one plant, a CMMS is enough and this article is not for you. If you manage assets with 20 to 40 years of service life spread across several sites, read on.
Comparison criteria
Six criteria structure the final table:
- Functional depth on assets: hierarchies, criticality, RCM, inspections, shutdown and turnaround management.
- Finance and procurement integration: valuation, fixed assets, maintenance cost allocation, spare parts sourcing.
- Field mobility: offline app, integration with technician scheduling.
- IoT and predictive: sensor data ingestion, asset health scoring, anomaly detection.
- Licensing model: per user, per module, per credit.
- European integrator ecosystem: availability of skills and risk of dependence on a single partner.
The 4 solutions
IFS Cloud EAM
Positioning. IFS offers a single platform covering ERP, EAM, supply chain and field service management (IFS). Its asset offering includes IFS Cloud EAM, IFS Ultimo (for lighter needs) and the Copperleaf investment planning tool, acquired recently according to IFS.
Strengths. Asset lifecycle from design to decommissioning, preventive, corrective and condition-based maintenance, RCM support, scheduling aligned with production, spare parts inventory tied to procurement. Multi-site support and capex planning (Copperleaf) are the differentiators for our angle.
Limitations. The gains IFS publishes (availability, maintenance costs) are vendor sales results: ask for verifiable customer references. Outside its flagship segments (energy, aerospace, heavy industry), its installed base in Europe is narrower than SAP’s.
Typical profile. An asset-intensive company that wants a single ERP + EAM + field system. See also our energy and utilities comparison (in French).
What this changes in a project. An EAM delivered on the same platform as the ERP removes most of the interfaces between work orders, parts procurement and accounting. The trade-off is a strong commitment: finance, procurement and maintenance are aligned on a single vendor and a single release cadence. Check that certified integrators are available in your country and sector before shortlisting the offer.
SAP S/4HANA Asset Management
Positioning. The historic Plant Maintenance module has become SAP S/4HANA Asset Management: equipment, functional locations, maintenance plans and work orders, natively inside the ERP. Around it, SAP offers SAP Asset Manager (a mobile app for technicians) and SAP Asset Performance Management (APM), a cloud service for asset health, reliability and risk analysis (SAP Learning).
Strengths. Native integration with finance, fixed assets, procurement and inventory, and a very large pool of integrators in Europe. APM adds the predictive and reliability layer.
Limitations. Predictive capabilities rely on complementary services (APM, mobile) that add to the license cost and to the complexity of the landscape. APM requires SAP EAM on S/4HANA or a recent ERP 6.0: it is a satellite, not a standalone engine. For ECC estates, standard maintenance ends at the end of 2027, with a possible extension to 2030 at extra cost (IBsolution). Migrating maintenance data (equipment records, plans, histories) is a project in its own right.
Typical profile. A group already on SAP, with centralized finance and procurement, that wants a single asset master.
What this changes in a project. If the SAP foundation already exists, the EAM builds on master data and financial flows that are already governed, which shortens the start-up phase. If you are starting from scratch, you are in effect buying a full ERP programme to get maintenance. The real work then lies in the quality of the equipment hierarchy, well before choosing mobile or predictive applications.
Infor EAM
Positioning. Infor EAM is a configurable asset management solution, available in the cloud, on-premises or hybrid, with mobility, barcode support and alerting on asset condition trends (Infor). A CloudSuite Facilities Management variant exists as a multi-tenant cloud offering for built-asset management.
Strengths. A long-established EAM product used in demanding maintenance environments, with the Infor OS platform for integration. Relatively light to deploy compared with a full ERP.
Limitations. We could not confirm Infor EAM’s current AI and predictive roadmap from public vendor sources: get it clarified in writing. If your ERP is not Infor, Infor EAM effectively becomes a best-of-breed EAM with interfaces you have to build. Our industrial ERP comparison (in French) details Infor’s positioning on the ERP side.
Typical profile. A manufacturer or infrastructure operator looking for a proven EAM, with or without an Infor ERP.
What this changes in a project. In a non-Infor landscape, plan the interfaces to the ERP from the scoping stage: parts procurement, cost allocation, fixed assets. Their cost and long-term upkeep often make the difference against an integrated ERP. Also get the roadmap, the available hosting modes and the integrators active in your region confirmed in writing, as these points are not exhaustively documented in public.
IBM Maximo Application Suite
Positioning. Maximo is a best-of-breed EAM, not an ERP. The suite includes Manage (EAM), Health, Monitor, Predict, Assist, Schedule Optimizer, visual inspection and inventory optimization (IBM). It can be deployed on-premises, on a hyperscaler under customer management, or as SaaS on AWS.
Strengths. Functional depth and an IoT/predictive layer built into the suite, with free choice of deployment. Maximo plugs into any ERP (SAP, Oracle, Microsoft, others).
Limitations. Credit-based licensing (AppPoints): each application and user type consumes a defined number of points (IBM). This makes cost comparison tricky and requires a precise simulation of your usage. ERP integration is your responsibility. Prices reported by third-party firms circulate but are not public on IBM’s side: we do not use them.
Typical profile. A multi-ERP group, or an operator whose EAM requirements exceed what the ERP offers, with the teams to carry the integration.
What this changes in a project. Choosing Maximo turns maintenance into a standalone product, with its own steering team, its own update cycle and its own interfaces to each ERP. That is an asset when your equipment spans more than one ERP, and a permanent burden otherwise. Ask for a credit-consumption simulation based on your real usage before any budget decision.
Comparison table
| Criterion | IFS Cloud EAM | SAP S/4HANA AM (+ APM) | Infor EAM | IBM Maximo |
|---|---|---|---|---|
| Asset depth and lifecycle | High, full lifecycle + capex (Copperleaf) | High on maintenance, lifecycle via related modules | High on maintenance and built assets | Very high, pure-play EAM |
| Finance and procurement integration | Native (same platform) | Native (same ERP) | Native with Infor ERP, otherwise interfaces | Via interfaces (any ERP) |
| Field mobility | Built in (field service management) | SAP Asset Manager | Infor EAM Mobile | Mobile app in the suite |
| IoT and predictive | IFS.ai, anomaly detection | APM (separate service) | Trend-based alerts; AI to be confirmed | Monitor, Health, Predict in the suite |

Cells marked “to validate” flag information that is not public: insist on a priced proposal that is comparable across vendors for the same scope.
How to read this table without being misled
A six-criterion table gives a direction, not a verdict. Three precautions avoid the most common misreadings.
Do not compare different scopes. “SAP” here means a bundle: the ERP’s Asset Management module, plus possibly the mobile app and APM. “IFS Cloud” includes the EAM within a single platform. “Maximo” is a suite in which each application is licensed separately. Comparing the price or depth of one component against that of an entire platform produces artificial gaps. Ask each vendor to price the same scenario: same sites, same number of maintenance users, same predictive scope.
Separate what is demonstrable from what is promised. A demo on the vendor’s own clean data says nothing about the quality of your data. Most EAM projects stumble less on the software than on the state of the asset base: duplicate equipment records, inconsistent nomenclatures from one site to another, intervention histories kept in spreadsheets. No EAM can fix a master data set that nobody governs.
Weight the criterion that is specific to you. For a network company, linear asset hierarchies and investment planning outweigh mobility. For a process site with an annual shutdown, shutdown scheduling and permit management come first. Assign your own weights to the six criteria before you see any offers, otherwise the demo will choose for you. The evaluation grid offered at the end of the article serves exactly this purpose.
The real issue: asset data
Whatever the vendor, the value of an EAM depends on three layers of data, and each has a different owner in the company.
- Technical master data (equipment, locations, bills of materials, maintenance plans) belongs to maintenance and methods. It drives the quality of work orders and failure analysis.
- Financial data (fixed assets, cost centers, cost allocation of interventions) belongs to finance. In an integrated ERP it is shared natively. With a separate EAM it flows through interfaces, and you must decide who handles reconciliation.
- Condition data (sensors, inspections, measurements) belongs to operations and industrial IT. Predictive maintenance only exists if these flows are reliable, timestamped and linked to the right asset in the master data.
A project that treats EAM as a mere software choice, without settling these three ownerships, often ends up with a technically compliant solution that teams work around. Conversely, a project that starts with a data quality workstream (even a modest one, on critical assets) significantly reduces risk, whichever solution is chosen. This echoes what we say about data migration in every ERP project: cleansing happens before migration, not after.
Recommendation by profile
Energy and utilities. IFS Cloud and SAP (with its utilities vertical) are the two natural candidates. IFS wins if the asset is at the center of the model; SAP if customer billing and finance dominate. Details in our dedicated comparison (in French).
Process industry. Planned shutdowns, criticality and compliance weigh heavily. Maximo or IFS for EAM depth; SAP if the ERP is already in place and the teams master PM.
Multi-site discrete manufacturing. If production is the core, an ERP with integrated EAM (SAP, IFS, Infor) avoids interfaces. Maintenance scheduling aligned with production is the decisive criterion.
Transport and infrastructure. Linear assets, fleets, built assets: IFS (linear assets and investment planning), Maximo or Infor depending on what you already have. Long-term capex favors offerings that cover investment, not just maintenance.
Integrated with the ERP or best-of-breed? A decision rule
The rule we apply: stay integrated as long as the cost of interfaces and data governance exceeds the functional gain. In practice:
- Choose the integrated EAM if your assets are mainly production equipment, if your ERP is already selected and if your maintenance teams accept a less deep tool.
- Choose a best-of-breed EAM (Maximo) if you run several ERPs, if the asset is the core of the business (networks, infrastructure), or if your reliability requirements go beyond the ERP standard.
Interface costs to estimate: synchronization of asset master data, spare parts order and receipt flows, cost feedback to finance, and version management when either side upgrades. Budget for them at tender stage, not after signing.
One governance point is often forgotten: with a separate EAM, two upgrade calendars coexist. Every ERP or EAM update means retesting the interfaces, and the maintenance window must be coordinated between two vendors, sometimes two integrators. With an integrated EAM this cost largely disappears, but in exchange you accept the ERP’s pace of change and, often, less functional depth on extreme reliability cases. There is no universal answer: the right question is how much friction your organization can absorb.
8 demo questions and contract traps
- Can you show an end-to-end scenario: sensor alert, work order, parts order, accounting allocation?
- Which predictive functions are native, and which are separate paid modules?
- How is the multi-site asset hierarchy standardized and governed?
- Does the mobile app work offline, and on what scope?
- How will you migrate our equipment histories and maintenance plans?
- What is the AI roadmap, and what do you actually commit to contractually?
- Which certified integrators operate in Europe, and what references do they have in our sector?
- What is the five-year total cost on our scope, interfaces included?
Contract traps. Credit-based licensing with no consumption simulation; predictive modules sold outside the base package; upgrade fees; caps on the number of sensors or connections; roadmap commitments that are not contractual.
5 classic mistakes in an EAM project
- Choosing the tool before cleaning up the asset hierarchy. Consequence: duplicated equipment records, unusable failure codes, and predictive features with nothing reliable to analyze. Countermeasure: freeze a common asset and failure taxonomy across all sites before the demo.
- Confusing a predictive demo with real capability. Consequence: a module bought for predictive maintenance that sits unused for lack of sensors, history or skills. Countermeasure: require a predictive use case run on your own data, and budget for sensors, connectivity and data science.
- Underestimating interfaces in a best-of-breed setup. Consequence: fragile procurement and accounting flows, mismatches between spare parts stock and the ERP, unbudgeted run costs. Countermeasure: include interfaces and their upkeep in the five-year total cost, and name one person accountable end to end.
- Forgetting the technicians. Consequence: a mobile app judged too heavy, entries made after the fact, poor field data, and therefore an EAM that does not reflect reality. Countermeasure: involve technicians and planners from the demos onward, and test offline use on site.
- Signing without a reversibility clause. Consequence: asset data held captive by a vendor for equipment that will live for decades. Countermeasure: write an export in an open format, data ownership and an exit plan into the contract.
Recommended selection approach
For a mid-sized company, a serious EAM tender runs in four stages, with no need to stretch it out.
- Scoping (a few weeks). Map your asset classes, identify the assets that are truly critical, formalize the target maintenance processes and decide who arbitrates between maintenance, finance and industrial IT. Without that sponsor, the three logics clash during demos.
- Shortlisting. Rule out offers that conflict with your hard constraints: ERP imposed by the group, required hosting (public cloud, sovereignty, on-premises), language and local presence of integrators. You are usually left with two or three candidates, rarely all four.
- Scripted demos. Impose your scenarios, not the vendor’s, using your real asset data, even if partial. Involve technicians and planners, not just management. The eight questions above provide the framework.
- Proof of value. Before signing, validate the full chain on a pilot site or a set of critical assets: signal, work order, part, cost in the ledger. A short pilot on one process is worth more than one more scoring table.
Add a reversibility clause to the contract, with export of your asset data in an open format. It is the best antidote to vendor lock-in, especially for assets whose lifespan outlasts any software generation.
