The short version

  • Only iDempiere has a free tier, so it costs nothing to try first.
  • Each has a real cost: Acumatica pricing is not published; the vendor directs buyers to a pricing review or an industry calculator instead; 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.
  • They diverge on capability: Acumatica covers Financial management, iDempiere covers Application dictionary.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Acumatica

  • Construction industry ERPnot iDempiere
  • Manufacturing business managementnot iDempiere
  • Distribution operationsnot iDempiere

iDempiere

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

Where each one falls short

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

Acumatica

  • Pricing is not published; the vendor directs buyers to a pricing review or an industry calculator instead
  • Cost is driven by transaction volume, data storage and resource levels, so spend rises with business activity rather than staying fixed
  • Charged per application implemented, so adding a module changes the price

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

Acumatica: How does Acumatica's pricing model work compared to traditional per-seat ERP systems?

Acumatica charges based primarily on the number of applications you implement, not user seats. Pricing adjusts based on business usage and resources (transaction volumes, user count, data storage needs) plus your chosen deployment license type. Unlimited users are included; you only pay for the functionality you need.

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.

Acumatica: Are there separate pricing calculators for different industries?

Yes, Acumatica offers industry-specific pricing calculators for Construction, Manufacturing, and Distribution to help estimate costs. You can also schedule a custom pricing review with an Acumatica partner for a tailored assessment.

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.

Acumatica: What happens if my business usage and data storage needs grow over time?

Acumatica allows you to adjust resource levels and data storage as you add users or expand usage. The transparent pricing model ensures you always know your costs, and you do not pay overages for unused features or unnecessary functionality.

Source
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.
