The short version

  • Only Dolibarr has a free tier, so it costs nothing to try first.
  • Each has a real cost: Dolibarr the core is deliberately shallow, so a serious requirement such as advanced manufacturing, EDI or a specific payment gateway usually means buying a DoliStore module from a third-party author, and the quality and maintenance of those modules varies widely.; 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: Dolibarr covers Module toggles, IQMS covers Single database ERP and MES.
  • 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.

Dolibarr

  • The core is deliberately shallow, so a serious requirement such as advanced manufacturing, EDI or a specific payment gateway usually means buying a DoliStore module from a third-party author, and the quality and maintenance of those modules varies widely.
  • Accounting was designed around French practice, and the chart of accounts, VAT model and fiscal exports need real work to satisfy accountants in the United States, the UK or Australia.
  • The interface is functional rather than designed and shows its age against Odoo, which makes internal adoption harder when staff are comparing it to consumer-grade software.
  • Upgrades between major versions can break paid third-party modules, because module authors update on their own schedules and there is no guarantee your combination will work on version 24 the day it ships.
  • Support is community forums unless you buy a partner contract, and the documentation is a wiki of uneven quality with substantial parts written in French, so English-only teams hit dead ends.

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

Dolibarr: Is Dolibarr genuinely free?

Yes. The full application is GPL with no user limit and no paid edition of the core. You pay only for hosting, optional DoliStore modules and optional partner support.

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.

Dolibarr: Can it run on shared hosting?

Yes, that is its main practical advantage. It needs only PHP and MySQL or MariaDB, so an ordinary cPanel account is enough.

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.

Dolibarr: How does it compare to Odoo?

Odoo is deeper and better presented but its useful modules are in the paid Enterprise edition and it needs a proper deployment. Dolibarr is thinner but free end to end and far easier to host.

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.

Dolibarr: Does it handle UK or US accounting?

Not comfortably out of the box. The accounting module reflects French conventions and needs configuration and often a local module to satisfy an accountant elsewhere.

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.
