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.; SAP S/4HANA implementation and integration costs routinely run to several times the software cost, and the subscription clock typically starts long before go live, so the first contract year buys much less usable production time than the headline suggests.
  • They diverge on capability: iDempiere covers Application dictionary, SAP S/4HANA covers HANA in-memory database.
  • 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Localisation depends on community contribution, so tax, payroll and statutory reporting for your country may be absent, out of date or maintained by one person, and you may end up funding it yourself.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.

SAP S/4HANA

  • Implementation and integration costs routinely run to several times the software cost, and the subscription clock typically starts long before go live, so the first contract year buys much less usable production time than the headline suggests.
  • Custom ABAP from an ECC installation must be assessed against the simplification list and either retired or rebuilt, and this remediation is normally the largest and most underestimated line in a brownfield conversion.
  • The public cloud edition constrains modification by design, so organisations that depend on non-standard processes are pushed either to change the process or to pay for the private edition, and that decision is often made after the contract is signed.
  • SAP intends extensions to live on the separately licensed Business Technology Platform, so the extensibility model that makes upgrades safe also adds a second subscription and a second set of skills to the total cost.
  • Exit is effectively impossible at reasonable cost, because the data model, the accumulated configuration and the trained staff around a large installation represent a switching cost that outweighs any competing vendor's discount, so the decision binds for a decade or more.

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.

SAP S/4HANA: What is the actual deadline for leaving ECC?

SAP has set mainstream maintenance for the older Business Suite to end in 2027, with paid extended maintenance available for a further period to 2030. Confirm the current dates and terms with SAP directly, because the commercial detail has been adjusted more than once and it determines your negotiating window.

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.

SAP S/4HANA: Greenfield or brownfield?

Brownfield carries your existing configuration and custom code forward, which is faster to start and slower to finish because everything must be remediated. Greenfield rebuilds on standard processes, which costs more in change management and leaves a cleaner system. The right answer depends mostly on how much of your existing configuration you would defend to a board.

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.

SAP S/4HANA: Is the public cloud edition cheaper?

To run, generally yes. Whether it is cheaper overall depends on whether your processes fit within its extensibility limits. If they do not, the savings evaporate into workarounds or into a move to the private edition.

iDempiere: Which database does it need?

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

SAP S/4HANA: How should I approach pricing negotiation?

Treat licence, infrastructure, BTP, the integrator and the internal backfill as one number and negotiate against it. Also settle indirect and digital access terms explicitly in writing, since usage from connected systems has been a recurring source of unbudgeted cost.
