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.; Zycus implementations run long and are consultant-led, so the gap between the sales demonstration and a configured live system is measured in quarters, during which the licence is already being paid.
  • They diverge on capability: IQMS covers Single database ERP and MES, Zycus covers Spend analysis.
  • Prices and features above were last checked on 31 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.

Zycus

  • Implementations run long and are consultant-led, so the gap between the sales demonstration and a configured live system is measured in quarters, during which the licence is already being paid.
  • The AI capability is marketed well ahead of what is typically enabled in a customer instance, and buyers should insist on seeing agentic features running on their own data before valuing them in a business case.
  • A large share of engineering and support capacity sits in India, so North American and European customers need coverage windows and escalation paths written into the contract rather than assumed.
  • The user interface across modules is inconsistent, reflecting different development eras, which raises training cost and reduces adoption among occasional requisitioners.
  • Pricing is entirely quoted and structured around spend under management, so a business whose spend grows faces increases unrelated to how much it uses the software.

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.

Zycus: Is it cheaper than Coupa or Ariba?

Usually on licence, and that price gap is the most common reason organisations shortlist it. Compare total cost including implementation, where the gap narrows.

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.

Zycus: Which module is strongest?

Spend analysis. Classifying dirty purchase data across multiple ERPs is where Zycus consistently performs well against alternatives.

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.

Zycus: How long is an implementation?

Plan for several quarters for a multi-module deployment. Phase it so one module delivers value before the rest go live.

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.

Zycus: What about support coverage?

Much of the delivery and support organisation is in India. Get the coverage hours, response times and escalation route into the contract explicitly.
