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.; Omnea it covers intake through contract only, so invoicing, payment and spend analysis remain with other systems and the promised end-to-end view is partial.
  • They diverge on capability: iDempiere covers Application dictionary, Omnea covers Intelligent intake.
  • 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 Omnea
  • 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 Omnea
  • 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 Omnea
  • 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 Omnea

Omnea

  • A regulated European business that must evidence supplier due diligence for every third party it engagesnot iDempiere
  • A company where security review is the slowest step in every software purchase and nobody can see where a request is stucknot iDempiere
  • An organisation renewing dozens of supplier contracts a year with no owner assigned to any renewal datenot iDempiere
  • A procurement team wanting to configure approval rules themselves rather than raising a ticket with engineeringnot 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.

Omnea

  • It covers intake through contract only, so invoicing, payment and spend analysis remain with other systems and the promised end-to-end view is partial.
  • As a younger vendor its integration library is narrower than the established suites, and connections into older on-premise ERP systems may require custom work.
  • Pricing is entirely quoted with no published tiers, and the vendor is small enough that comparable public reference points are scarce.
  • Third-party risk depth is good for questionnaire-driven assessment but lighter than a dedicated GRC platform on continuous monitoring and control mapping, so heavily regulated firms may still need both.
  • Its value is concentrated in organisations with a formal procurement policy and a compliance obligation; a company without either gets an approval workflow tool at enterprise pricing.

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.

Omnea: How does it differ from Zip?

Both do intake and approval orchestration. Omnea puts third-party risk assessment inside the same workflow and has a European base and compliance orientation, which matters under GDPR and DORA.

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.

Omnea: Does it replace our ERP?

No. It handles the request through contract stage and hands off to the finance system for purchase orders, invoicing and payment.

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.

Omnea: What does it cost?

Not published. It is an annual subscription quoted by company size and modules.

iDempiere: Which database does it need?

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

Omnea: Do we still need a GRC tool?

Possibly. Omnea handles supplier due diligence well; continuous control monitoring and framework mapping remain a dedicated GRC job.
