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.

Omie

  • Specific plan pricing not listed; pricing varies based on company size and revenue
  • Pricing model defined as 'conforme o porte e o faturamento da empresa' (based on company size and revenue)
  • Offered in Portuguese only with Portuguese 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.

Omie: How much does Omie cost?

Omie ERP pricing is determined based on company size and revenue rather than fixed tiers. Specific plan prices are not listed on the website; contact a consultant for pricing based on your business needs.

Source
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.

Omie: Does Omie offer a free trial?

Yes, Omie offers a 7-day free trial at R$0.00 with no credit card required. The trial includes cloud-based system access, premium customer support, and full access to core features with quick cancellation available anytime.

Source
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.

Omie: What is included in the Omie free trial?

The 7-day free trial includes a 100% online cloud-based system, premium customer support, simple online contracting, and full access to core features without credit card requirements.

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.
