  • 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.; Maintenance Connection implementation is a project measured in months, and the cost of that work frequently exceeds the first year of licensing
  • They diverge on capability: iDempiere covers Application dictionary, Maintenance Connection covers Deep asset hierarchies.
  • 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.

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depends on community contribution, so tax, payroll and statutory reporting for your country may be absent, out of date or maintained by one person, and you may end up funding it yourself.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

Maintenance Connection

  • Implementation is a project measured in months, and the cost of that work frequently exceeds the first year of licensing
  • Pricing is entirely quote-based with no published entry point, so early comparison is impossible
  • The interface reflects its age and is a common objection from technicians used to consumer-grade mobile apps
  • Overpowered for single-site operations, where the configuration burden buys capability that will not be used
  • Accruent sells a broad portfolio, so the buying process involves more product than a maintenance team asked for

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.

Maintenance Connection: Who is Maintenance Connection for?

Multi-site organisations with large asset registers and formal maintenance governance. Below that scale, the configuration effort is not repaid.

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.

Maintenance Connection: What does it cost?

Not published. It is quoted, and implementation is a separate line that often exceeds first-year licensing.

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.

Maintenance Connection: How does it differ from MaintainX?

Almost entirely. This is an enterprise system configured to enforce an existing process; MaintainX is a mobile app a team adopts in a day. They rarely appear on the same shortlist honestly.

iDempiere: Which database does it need?

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

Maintenance Connection: Is it good for regulated industries?

That is its strongest case. Audit trails, evidence of preventive regimes and multi-site consistency are what it is built to produce.

Maintenance Connection: What is the biggest risk in adopting it?

Under-resourcing implementation. A partially configured enterprise CMMS is worse than a well-run simple one, and this is the most common way these projects disappoint.
