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.; Litmus Edge pricing is by site and data point, so a large tag count at one plant can cost more than a modest tag count spread over several, which is the opposite of how most manufacturers plan a rollout.
  • They diverge on capability: IQMS covers Single database ERP and MES, Litmus Edge covers Prebuilt driver library.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

IQMS

  • An injection moulding or plastics processor that needs cycle level machine data to cost jobs accuratelynot Litmus Edge
  • A repetitive discrete manufacturer running many short jobs where scheduling depends on knowing real machine availabilitynot Litmus Edge
  • An automotive component supplier that must meet EDI release schedules and hold traceability to satisfy a customer auditnot Litmus Edge
  • A plant currently reconciling an ERP against a separate MES and finding the two never agreenot Litmus Edge

Litmus Edge

  • A manufacturer with twenty plants and five PLC brands that needs one data acquisition standard rather than twenty bespoke integrationsnot IQMS
  • Feeding a cloud data warehouse or lakehouse with normalised production data without asking the controls team to write cloud connectorsnot IQMS
  • Retrofitting data collection onto old CNC machines and robots where the protocol support is the hard part, not the analyticsnot IQMS
  • Adding local buffering and computation at sites with unreliable WAN links so cloud outages do not create gaps in production historynot IQMS

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.

Litmus Edge

  • Pricing is by site and data point, so a large tag count at one plant can cost more than a modest tag count spread over several, which is the opposite of how most manufacturers plan a rollout.
  • The entry package sits around $1,500 per month, an awkward number for a single-site pilot given that the product is infrastructure with no visible output of its own until something downstream consumes it.
  • Litmus does no analytics, so the business case always depends on a second purchase; the platform on its own produces no result a plant manager can see.
  • Full pricing beyond the entry tier is not published and the Growth and Scale packages are quoted, so scaling costs are unknown at the point you commit to the architecture.
  • A capable controls team can approximate a single-site deployment with an open-source broker and a driver gateway for a fraction of the cost, so the value case depends entirely on how many sites you are managing centrally.

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.

Litmus Edge: Does Litmus Edge do analytics or dashboards?

Only lightweight edge computation and basic visualisation. It is a data acquisition and normalisation layer; the analysis happens in whatever you send the data to.

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.

Litmus Edge: How is it priced?

By number of sites and number of data points, in packages. The entry package starts around $1,500 per month; larger tiers are quoted.

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.

Litmus Edge: Can it replace my historian?

No. It buffers and forwards but is not a long-term historian. Most deployments send data into a historian, warehouse or lakehouse.

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.

Litmus Edge: Does it need Litmus hardware?

No. It runs on standard industrial PCs, virtual machines or containers; there is no proprietary appliance requirement.
