The short version

  • 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.; Tryton ordinary series are supported for only one year, so any deployment not pinned to a long term support major version needs a funded upgrade project every twelve months, which is the largest hidden cost of running Tryton.
  • They diverge on capability: iDempiere covers Application dictionary, Tryton covers Modular installation.
  • Prices and features above were last checked on 31 August 2026.

iDempiere

  • A distributor needing multi-company books in one database with analytic accounting on topnot 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Localisation depends on community contribution, so tax, payroll and statutory reporting for your country may be absent, out of date or maintained by one person, and you may end up funding it yourself.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.

Tryton

  • Ordinary series are supported for only one year, so any deployment not pinned to a long term support major version needs a funded upgrade project every twelve months, which is the largest hidden cost of running Tryton.
  • There is no vendor to buy support from, only a list of independent service providers, so procurement teams that require a single accountable supplier with an SLA have to construct one themselves.
  • The module ecosystem is far smaller than Odoo or ERPNext, so region-specific tax rules, payroll and industry add-ons frequently have to be written rather than installed.
  • Out of the box reporting is thin and there is no built-in business intelligence layer, so most deployments end up exporting to an external tool to get management reporting.
  • Documentation and community discussion are functional but sparse compared with commercial ERPs, which lengthens implementation for teams that have not worked with Tryton before and makes hiring experienced consultants harder.

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.

Tryton: What licence is Tryton under?

The platform and official modules are GPL-3.0-or-later. There is no paid enterprise edition.

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.

Tryton: How long is a release supported?

Series are released every six months and supported for one year. Major versions get five years of long term support, so pin to an LTS release unless you can fund annual upgrades.

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.

Tryton: Is there a hosted version from the project?

No. The foundation lists independent service providers who offer hosting and support commercially.

iDempiere: Which database does it need?

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

Tryton: How does it differ from Odoo?

Tryton has no open core split, so there is no paid edition holding back features, but the module ecosystem and partner network are much smaller.
