The short version

  • Only iDempiere has a free tier, so it costs nothing to try first.
  • Each has a real cost: iDempiere there is no vendor, so there is no support contract, no service level agreement and nobody to escalate to; you either build the skills internally or you depend entirely on a local partner whose quality you must judge yourself.; 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.
  • They diverge on capability: iDempiere covers Application dictionary, IQMS covers Single database ERP and MES.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

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

iDempiere

  • A distributor wants multi-organisation, multi-currency accounting and warehouse costing without a per-user ERP licence that scales with headcount.not IQMS
  • An organisation that has been caught by an open core vendor moving features into a paid tier wants an ERP with no company that can make that decision.not IQMS
  • A team needs heavy customisation of screens, fields and approval workflows that must survive version upgrades, which the application dictionary makes possible without forking.not IQMS
  • A public sector or university body in Latin America or Indonesia needs a locally supportable ERP where the source and the implementation skills are both available in-country.not IQMS

IQMS

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

Where each one falls short

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

iDempiere

  • There is no vendor, so there is no support contract, no service level agreement and nobody to escalate to; you either build the skills internally or you depend entirely on a local partner whose quality you must judge yourself.
  • It demands real Java, OSGi and PostgreSQL administration, so the running cost is a systems engineer rather than a subscription, and that engineer is harder to hire than a PHP developer.
  • The ZK-based interface is dense and dated, with a data-entry feel inherited from Compiere that staff used to modern software find hostile, which drives up training cost.
  • Localisation depends on community contribution, so tax, payroll and statutory reporting for your country may be absent, out of date or maintained by one person, and you may end up funding it yourself.
  • The documentation is a community wiki with gaps and stale pages, and much of the practical knowledge sits in forum threads and partner heads rather than in anything you can hand to a new administrator.

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.

Answered from the vendors’ own pages

iDempiere: Is iDempiere the same as ADempiere or Compiere?

It shares the lineage. iDempiere forked from ADempiere in 2011 to rebuild the platform on OSGi, and it is the branch that remains actively developed.

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.

iDempiere: Is there a paid or enterprise edition?

No. There is no commercial owner and no feature gating. Money is spent on implementation partners and hosting, not on licences.

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.

iDempiere: What does it actually cost to run?

Nothing in licence fees, and a great deal in skills: expect a partner implementation and ongoing Java and PostgreSQL administration, which for a mid-sized company is comparable to a commercial subscription.

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.

iDempiere: Which database does it need?

PostgreSQL or Oracle. PostgreSQL is the mainstream community choice and the one most partners deploy.

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.
