The short version

  • 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.; Zip it is a layer on top of systems you already pay for, so the business case rests on adoption and cycle time rather than replacing a licence, and that is harder to defend to a finance director cutting software spend.
  • They diverge on capability: iDempiere covers Application dictionary, Zip covers Unified 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.

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depends on community contribution, so tax, payroll and statutory reporting for your country may be absent, out of date or maintained by one person, and you may end up funding it yourself.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

Zip

  • It is a layer on top of systems you already pay for, so the business case rests on adoption and cycle time rather than replacing a licence, and that is harder to defend to a finance director cutting software spend.
  • Value depends entirely on integration depth into your specific ERP and ticketing tools, and a shallow connector reduces it to a workflow tool that someone rekeys out of.
  • Pricing is not published and is structured around company size and integration scope, so buyers cannot benchmark without peer references.
  • If procurement policy itself is unclear, Zip encodes the confusion: the tool routes requests according to rules someone must first write, and organisations without that clarity see slow implementations.
  • It does not do sourcing, auctions or spend analysis, so organisations expecting a full procurement capability will still need a suite or specialist tools alongside it.

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.

Zip: Is this the buy now pay later company?

No. This is Zip at ziphq.com, a procurement orchestration platform, unrelated to the payments company of the same name.

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.

Zip: Does it replace Coupa or Ariba?

No, and that is the point. It sits in front of them, providing the intake and approval experience employees actually use, and writes back into the suite.

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.

Zip: What does it cost?

Not published. Quoted by company size, modules and the integrations you need. Get peer benchmarks before negotiating.

iDempiere: Which database does it need?

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

Zip: What is the prerequisite for success?

A written procurement policy. Zip automates the routing rules you give it; if nobody can say who approves what, implementation stalls.
