The short version

  • Each has a real cost: IQMS dassault Systemes acquired the product in 2018 and renamed it, which changed the sales channel, the support relationship and the roadmap owner, so a buyer needs explicit commitments on release cadence rather than a history of independence that no longer applies.; Maintenance Connection implementation is a project measured in months, and the cost of that work frequently exceeds the first year of licensing
  • They diverge on capability: IQMS covers Single database ERP and MES, Maintenance Connection covers Deep asset hierarchies.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

IQMS

  • Dassault Systemes acquired the product in 2018 and renamed it, which changed the sales channel, the support relationship and the roadmap owner, so a buyer needs explicit commitments on release cadence rather than a history of independence that no longer applies.
  • This is a discrete and repetitive manufacturing system, not a process one, so a batch producer needing formulation, potency, catch weight or co-product handling will hit capability gaps that configuration cannot close.
  • The product has an on premise heritage with an underlying commercial database, so a deployment carries database licensing and administration skills as costs that sit outside the ERP quote.
  • Its depth is on the shop floor rather than in the office, so organisations with complex multi-entity consolidation, international statutory reporting or sophisticated financial planning needs generally find the finance side thinner than the manufacturing side.
  • The knowledge base is split across two product names and two eras, so searching for help returns a mixture of IQMS-era community material and current DELMIAworks documentation, and it is not always obvious which applies to your version.

Maintenance Connection

  • Implementation is a project measured in months, and the cost of that work frequently exceeds the first year of licensing
  • Pricing is entirely quote-based with no published entry point, so early comparison is impossible
  • The interface reflects its age and is a common objection from technicians used to consumer-grade mobile apps
  • Overpowered for single-site operations, where the configuration burden buys capability that will not be used
  • Accruent sells a broad portfolio, so the buying process involves more product than a maintenance team asked for

Answered from the vendors’ own pages

IQMS: Is IQMS the same as DELMIAworks?

Yes. Dassault Systemes acquired IQMS in 2018 and markets the product as DELMIAworks. The underlying application, EnterpriseIQ, is the same lineage, but contracts, support and the sales channel are now Dassault's.

Maintenance Connection: Who is Maintenance Connection for?

Multi-site organisations with large asset registers and formal maintenance governance. Below that scale, the configuration effort is not repaid.

IQMS: Why choose this over an ERP plus a separate MES?

Because the interface between them is the usual failure point. One database means production status, scrap and costing agree by construction. The cost of that is a narrower product that suits a specific kind of manufacturer rather than any manufacturer.

Maintenance Connection: What does it cost?

Not published. It is quoted, and implementation is a separate line that often exceeds first-year licensing.

IQMS: Does it suit process or batch manufacturing?

No. It was built around discrete and repetitive production. Formulation, potency adjustment and co-product handling are the domain of process ERP and you should look at a specialist for that.

Maintenance Connection: How does it differ from MaintainX?

Almost entirely. This is an enterprise system configured to enforce an existing process; MaintainX is a mobile app a team adopts in a day. They rarely appear on the same shortlist honestly.

IQMS: What should I check before buying under the current ownership?

Ask for the published release history since the acquisition, the support escalation path, who implements it in your region and whether they are Dassault staff or a partner, and what integration with the rest of the Dassault portfolio is assumed in the roadmap.

Maintenance Connection: Is it good for regulated industries?

That is its strongest case. Audit trails, evidence of preventive regimes and multi-site consistency are what it is built to produce.

Maintenance Connection: What is the biggest risk in adopting it?

Under-resourcing implementation. A partially configured enterprise CMMS is worse than a well-run simple one, and this is the most common way these projects disappoint.
