The short version

  • Only iDempiere has a free tier, so it costs nothing to try first.
  • Each has a real cost: Comarch no pricing is published anywhere on the site for any product line; the only route to cost is a Kontakt z konsultantem (Consultant Contact) request for a quote; 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.

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

Where each one falls short

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

Comarch

  • No pricing is published anywhere on the site for any product line; the only route to cost is a Kontakt z konsultantem (Consultant Contact) request for a quote
  • The ERP line is split across three separately scaled products (Optima for SMBs, XL, Enterprise) with no published criteria distinguishing which a given company should quote

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Localisation depends on community contribution, so tax, payroll and statutory reporting for your country may be absent, out of date or maintained by one person, and you may end up funding it yourself.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

Comarch: How much does Comarch cost?

Comarch does not publish pricing online. The company offers enterprise ERP solutions like Comarch ERP Enterprise, Comarch ERP XL, and Comarch ERP Optima. Pricing is determined through custom quotes based on organization size and specific requirements. Contact Comarch sales at (12) 646 1000 or through their consultant contact form to request a quote.

Source
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.

Comarch: What is Comarch's pricing model?

Comarch uses a quote-based pricing model tailored to enterprise customers. The company does not offer self-serve pricing or standardized subscription tiers. Customers must request personalized pricing from the sales team based on their deployment requirements.

Source
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.

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.

iDempiere: Which database does it need?

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