The short version

  • Each has a real cost: Aras Innovator aras publishes no prices at all, so you cannot sanity-check a quote against a list price and every negotiation starts from the vendor knowing more than you do.; 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.
  • They diverge on capability: Aras Innovator covers Model-based configuration, iDempiere covers Application dictionary.
  • 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.

Aras Innovator

  • A manufacturer whose current PLM cannot be upgraded because past customisations would break, and who wants configuration that survives releasesnot iDempiere
  • An engineering organisation that needs requirements, quality and change management under one data model without buying three modulesnot iDempiere
  • A medical device or aerospace firm needing full traceability from requirement to as-built serial numbernot iDempiere
  • A company piloting PLM on a real programme using the free 50-user Community Edition before committing budgetnot iDempiere

iDempiere

  • A distributor wants multi-organisation, multi-currency accounting and warehouse costing without a per-user ERP licence that scales with headcount.not Aras Innovator
  • 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 Aras Innovator
  • 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 Aras Innovator
  • 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 Aras Innovator

Where each one falls short

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

Aras Innovator

  • Aras publishes no prices at all, so you cannot sanity-check a quote against a list price and every negotiation starts from the vendor knowing more than you do.
  • The platform ships as a toolkit rather than a configured process, so a first implementation is typically a six to twelve month engagement with an integrator, and services frequently cost more than the first two years of subscription.
  • The Community Edition is capped at 50 named users, gets only annual releases and excludes Aras-performed upgrades, so it is a genuine free tier but a deliberately awkward place to stay.
  • Configuration flexibility invites over-customisation; organisations that model every local exception end up with a system only two internal people understand, which is the same trap they left their previous PLM to escape.
  • CAD connectors are not all equal in maturity, and some are excluded from the base subscription, so a shop standardised on a less common CAD tool should confirm connector scope in writing before signing.

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.

Answered from the vendors’ own pages

Aras Innovator: Is Aras Innovator open source?

No. The source is not open. The Community Edition is free of licence fee for up to 50 named users under a revocable licence, which is not the same thing.

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.

Aras Innovator: Can I buy a perpetual licence?

No. Aras sells subscription only. If a perpetual PLM licence is a procurement requirement, Aras is out.

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.

Aras Innovator: Do upgrades cost extra?

No, and that is the central commercial claim. Aras performs upgrades of subscriber environments, including customised ones, as part of the subscription.

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.

Aras Innovator: How many modules do I have to buy?

One subscription covers all applications. Some CAD connectors are the exception, so confirm yours is in scope.

iDempiere: Which database does it need?

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