The short version

  • Only ADempiere has a free tier, so it costs nothing to try first.
  • Each has a real cost: ADempiere there is no company behind it, so there is no support contract to buy, no SLA, no escalation path and no roadmap commitment; if your implementation partner leaves the market you own the problem entirely.; 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: ADempiere covers Application dictionary, Omnea covers Intelligent intake.
  • 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.

ADempiere

  • There is no company behind it, so there is no support contract to buy, no SLA, no escalation path and no roadmap commitment; if your implementation partner leaves the market you own the problem entirely.
  • The official website adempiere.net does not resolve, which strands most of the historic documentation and tutorials that search engines still point at and makes onboarding a new developer considerably harder.
  • The last conventional stable release, 3.9.4, is from January 2023, so despite ongoing GitHub activity a buyer evaluating on release cadence sees a project moving slowly.
  • iDempiere, a later fork of the same codebase, absorbed much of the developer community, so ADempiere competes for contributors with its own descendant and is the smaller of the two ecosystems.
  • The interface and the Java Swing heritage feel dated, and staff coming from a modern cloud ERP will need training and will complain; expect resistance from finance and warehouse users during rollout.

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

ADempiere: Should I choose ADempiere or iDempiere?

Look at iDempiere first. It is a later fork of the same codebase with a more active community and a modular OSGi architecture. Choose ADempiere if a specific partner or localisation you need only exists there.

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.

ADempiere: Is ADempiere free?

The software is GPL licensed with no licence fee. The cost is implementation, customisation and permanent in-house maintenance, which for a real deployment is substantial.

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.

ADempiere: Is the project still alive?

Development continues on GitHub with commits into 2026, but the official website is down and the last stable release is from January 2023. Treat it as maintained rather than actively advancing.

Omnea: What does it cost?

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

ADempiere: What is the application dictionary?

It is the metadata layer inherited from Compiere that stores the definition of every window, field and validation rule as data, so you can change the application without touching source code.

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.
